tricks for getting the most out of this unique piece of gear.

The JamHub team wants to do everything possible to inspire you to play more music, create more music, and have more

fun doing it. Isn’t that what being a musician is all about?

Owner’s Manual: a new approach

Owner’s manuals are funny things. They are often written for (and by) “left brain” analytical types. Yet they most benet

“right brain” creative people who usually disregard them. So we decided to try something different. Since musicians are

left and right brain individuals, why not design a manual that satises both sides of the brain. So in our manual, from

time-to-time, the pages will split like this:

Left Brain: analytical, verbal, numeric Right Brain: creative, visual, emotional

On this side of the page you’ll nd things On this side of the page you’ll nd things

that are more left brain targeted, like: that are more right brain targeted, like:

• Numbers • Feature benets

• Specs • Tips and tricks

• Feature descriptions • Comic relief

• Technical facts

How to make the most of this document

Read the JamHub Quick Start Guide twice and you’ll be 90% of the way there. You should thoroughly understand the

“Connections” and “Setting the Levels” sections. If you know this stuff well, you’ll always have a great jam session. If you

don’t, you could be frustrated at times. All musicians need to understand setting levels. You’ll need it for recording, live

performances and for JamHub rehearsals. It’s easy stuff and essential to having a great jam session. So please learn it.

JamHub® Silent Rehearsal Studio Safety Guide

This Safety Guide contains important safety and handling information for JamHub.

Handling JamHub and Using Power Supply Cord

Do not bend, drop, crush, puncture, incinerate or open JamHub. Power supply cords should be routed so that they are

not likely to be walked on or pinched by items placed upon or against them.

Water and Moisture JamHub should not be used near water (e.g. near a bathtub, washbowl, kitchen sink,

laundry tub, in a wet basement, or near a swimming pool, etc.). Do not use JamHub in

rain. Take care not to spill any food or liquid into or onto JamHub.

Non-use Periods The power cord of the JamHub should be unplugged from the outlet when left unused for

a long period of time.

Use of Power Adapter The JamHub Power Adapter may become warm during normal use. Always allow adequate

ventilation around the JamHub Power Adapter and use care when handling. Unplug the

JamHub Power Adapter if any of the following conditions exist:

• The power cord or plug has become frayed or damaged.

• The adapter is exposed to rain, liquids, or excessive moisture.

• The adapter case has become damaged.

• You suspect the adapter needs service or repair.

• You want to clean the adapter.

Avoiding hearing damage Permanent hearing loss may occur if headphones are used at high volume. If you

experience ringing in your ears or mufed speech, stop listening and have your hearing

checked. The louder the volume, the less time is required before your hearing could be

affected. Hearing experts suggest that to protect your hearing you should limit the amount

of time you use headphones at high volume.

Heat and Ventilation JamHub should be situated away from heat sources such as radiators, heat registers,

stoves, or other appliances (including ampliers) that produce heat, and in a manner that

allows for proper ventilation.

Cleaning JamHub should be cleaned with a soft, damp cloth.

Damage requiring service Never attempt to repair JamHub yourself. JamHub does not contain any user-serviceable

parts. For service information, go to www.JamHub.com. JamHub should be serviced by

qualied service personnel when:

• the power cord or the plug has been damaged; or

• objects have fallen, or liquid has been spilled into JamHub; or

• JamHub has been exposed to rain or moisture; or

• JamHub does not appear to operate normally or exhibits a marked change in

performance; or

• JamHub has been dropped, or the enclosure has been damaged.

Read all safety information below and operating instructions before using JamHub to avoid

injury. For detailed operating instructions, see the User Guide that follows this Safety Guide.

Failure to follow these safety instructions could result in re,

electric shock, or other injury or damage.

JamHub® – What is it?

Left Brain:

The Table of Contents below will help guide you

through each section of the manual and get you to

things quickly and efciently.

Right Brain:

The Table of Contents below is probably not necessary

because we know you’re just going to ip through

the manual until you nd the picture you think best

answers your question. That’s why we included so

many illustrations.

Left Brain:

A JamHub is a multi-input, multi-audio channel device

designed specically to allow musicians to jam or re-

hearse quietly and play more often. This typically leads

to improving the band’s skills very rapidly. Scientic

studies show that better quality practicing leads to faster

skills development. Some say, “Practice doesn’t make per-

fect, perfect practice makes perfect.” Use your JamHub

to make the best rehearsals possible.

Simply plug in your practice gear, like a modeling amp,

a keyboard, your microphone, and your headphones.

Have your band mates do the same. Everyone can cre-

ate a mix that’s right for them and you’re ready to go.

You’ll nd with a JamHub that you can play longer,

without disturbing others, and without burning out your

ears. Most importantly, because there aren’t several loud

amps in a small room muddying up the music, the clarity

of your jam is greatly enhanced and rehearsals are much

more productive.

Lastly, with the JamHub’s SoleMix™ controls, you control

what you hear. So volume wars are a thing of the past.

Bass player too loud? Just reach over to your JamHub

section and turn him/her down. And the bass player can

turn up the drums and turn down your guitar so he/she

can lock into the groove. Everyone hears what they need

to hear to ensure the band is improving faster.

Right Brain:

A JamHub lets you jam with your band anywhere,

anytime in near silence. And the experience rocks.

Each musician picks a color section and plugs in their

instruments, microphones and headphones, then,

using their section’s SoleMix controls, creates

their own perfect mix.

You’ll hear yourself with amazing new clarity and no

more volume wars. So, not only will you be jamming

more often, but you’ll also be getting better faster and

working out totally new arrangements to the same old

songs.

Improving and enjoying your music has never been this

easy.

Step 2: Connections

1. Plug in the power adapter. The blue LED light tells you when the JamHub

is ready.

2. Pick a section to call your own.

3. Plug in your instrument with a Stereo (TRS) cable using your instrument’s or amp’s headphone jack for the best

results. Often the headphone jack’s output is optimized for headphone listening.

4. Plug in a microphone.

5. Plug in your headphones.

6. Tell your band mates to follow steps 2 through 5.

7. OK, you’re almost ready to rock. But rst some very important info:

IMPORTANT! Connect your instruments with a stereo instrument cable or stereo adapter!

When connecting your instrument, it’s important to use a stereo cable, here’s why. Your JamHub is a stereo environment,

just like the real world. Because your instrument’s output often includes reverb and other stereo effects, we designed the

JamHub to accept a stereo signal and make the listening experience great. If you connect to the JamHub with a mono

cable, like a standard guitar cable, your sound will be 100% in the left ear, this is because of the way a mono cable works

with a stereo jack.

You can use the included mono 1/4” female to stereo 1/4” male adapter if you need to use a mono cable. But we recom-

mend against using this solution in the long run. Audio coming from this “spit mono” signal is not as good as a stereo

signal. This is because of the way the human hearing system works. In a live jam, each ear hears something slightly

different because of reections in the room. With “split mono” each ear hears the exact same thing and that reduces our

perception of clarity. Therefore “split mono” is not as optimal as a true stereo signal, so we recommend using a stereo

signal and a stereo cable.

Left Brain:

Turn all the knobs on the JamHub® to zero (100%

counterclockwise) to protect the device and your

headphones from grounding and connection pops.

Now that everyone’s connected, a good starting mix is

your control at 2:00 and every one else at 12:00.

Right Brain:

Protect your ears and your gear: turn all knobs down

on every section of the JamHub before putting on the

headphones. Okay, do this NOW.

Now that everyone’s connected a good starting mix is

your control at 2:00 and every one else at 12:00.

Step 5: Turn up the headphone volume

(A plea from the JamHub inventor: Please be careful with your hearing. You’re going to want to keep play-

ing for a long, long time and you’ll want your ears in good working order.)

Step 3: Setting the trim levels

1. Use the double knob labeled “trim” to set your input gain (note: you don’t need to put on headphones to do this step).

Use the light under the dual trim knobs to set this knob to the right level for your inputs by follwing steps 2 and 3.

2. Speak into the mic and turn the outer/bottom knob up (clockwise) until the LED turns yellow. Then turn it back a little.

3. Play your instrument and turn the inner/top knob up (clockwise) until the LED turns yellow. Then turn it back a little.

4. Watch your trim settings throughout the jam session. Sometimes input levels can change as the band gets warmed up.

Use the table below as your guide.

In summary

Step 4: Pick a virtual location with the stage control

Left Brain:

Start with the headphone output control at zero

(100% counterclockwise) and slowly turn it up.

Because every section of the JamHub® has its own

individual mix, output adjustments will vary by player.

So start low and turn up slowly. Also, headphones have

a wide variety of impedances. While your JamHub is

designed to handle them all, the setting of each head-

phone volume knob might be different.

Right Brain:

Don’t burn out your ears. Bring the volume up

s-l-o-w-l-y. Also, while the JamHub does work with

most headphones, it can’t make cheap or poor quality

ones sound better. Sorry, we’re gear makers not miracle

workers.

Left Brain:

green = signal

yellow = near clipping (-6dB)

red = preamp clipping (+6dB)

Right Brain:

green = good

yellow/orange = caution

red = bad

Left Brain:

The stage control is simply a pan or balance control

that helps ensure that musicians don’t crowd the mix.

Because our hearing system has two receptors sepa-

rated by about 6 inches (known as your ears) we have

the ability to perceive sounds coming from different

locations due to slight delays in arrival time. Great audio

engineers have known for a long time that by “moving”

things to their own sonic location, our hearing system is

optimized and we experience greater clarity. There’s a

great article on Wikipedia about this amazing property

of our hearing system. Read all about it here:

http://en.wikipedia.org/wiki/Cocktail_party_effect

Right Brain:

Does everyone in your band stand in the middle of the

stage when jamming? Of course not. So spread out

sonically with the Stage Control. The experience will be

similar to what happens when you’re playing live. You’ll

hear things with greater clarity and the jams will be

more enjoyable. If you want to understand why great

recordings have instruments panned to different

locations, read the “left brain” side of this box and

the article on Wikipedia mentioned over there. Learn-

ing to spread out sonically will help your band get ready

for the recording studio as well.

Step 7: SoleMix remote setup

All JamHub® models allow you to add a SoleMixTM remote. If you purchased a

JamHub GreenRoom or TourBus model, it is included. The BedRoom model has 1

SoleMix remote connector. GreenRoom and TourBus both have 4. If you want to

add one or more SoleMix remotes to your JamHub system, they are available at

your authorized JamHub dealer.

The SoleMix remote lets you create a unique mix for the output jack on the

remote. Each remote has its own headphone jack so you can have complete con-

trol over your mix and output level with one cable from the JamHub main unit.

It is not connected to any specic section because it controls output only.

The SoleMix remote was created so that drummers, keyboard players and

musicians who are “stuck” behind their gear can make mix changes without

moving to the main JamHub unit. The remote acts just like the SoleMix section

on the JamHub but without the input section (input trims, jacks and stage con-

trol). Below is an illustration of a remote setup option.

You are now ready to start jamming. We encourage you to read the full manual. There are still a few things about your

JamHub that need to be explained. And don’t forget to visit the “Community” section at www.JamHub.com to let us know

you’re out there and learn about other JamHub owner experiences.

Step 6: Using the SoleMix control section

See the “Effects Section” on page 14 for more information

JamHub GreenRoom

JamHub

SoleMix Remote

Left Brain:

The SoleMix remote is its own output section that

taps all of the input busses. For example, a JamHub

GreenRoom has 7 SoleMix sections on the main unit,

plus one remote. So there are 8 possible unique mixes

right out of the box. Should you buy three additional

remotes, and maximize the output capability of the

GreenRoom model, you’ll have 7 output sections on

the main unit and 4 output sections via remotes for a

grand total of 11 potential mixes from one JamHub. We

believe that this capability will allow for a wide array of

setup options, giving you a lot of choices and capacity

for years to come.

Right Brain:

The SoleMix remote is like adding another output to the

system; it’s like a mixer without any inputs. And, you

can add a remote to any JamHub system.

(Note: Even though the SoleMix remote has 7 mix

controls like GreenRoom and TourBus, it works just

as well with BedRoom; audio controls 5 and 6 are

simply inactive.)

Effects return is

located under

the headphone

volume on each

SoleMix section

of the JamHub’s

main unit. It’s

also its own knob

on the SoleMix

remote.

Want to hear less of the musician in

section 4? Turn down the #4 knob.

Want to hear more of the musician

in section 3? Turn up the #3 knob.

Left Brain:

Each SoleMixTM control section allows you to tap the

many stereo busses located within your JamHub®, giv-

ing you an exceptional level of control over what each

musician hears as their output mix.

Right Brain:

Each SoleMix control section is like an individual mixer.

You get to create the mix that’s right for you while

the other band members do the same. Think of the

JamHub‘s controls as many mixers put together in one

portable, affordable unit. Each person controls their

own mix and their own creative space.

Want to hear more or less effects?

Turn the effects return knob up

or down.

The 1- R switch for auditing your recording mix

The 1 - R switch is for listening to the mixes coming from section 1 and the

R section. If you’re the person responsible for the recording mix, you’ll

need to hear both the R mix as well as your own mix on section 1. So we

designed the JamHub® with a handy little switch that allows you to quickly

ip back and forth between these two sections.

Effects engine and settings

The effects engine in your JamHub silent rehearsal studio allows you to

create a “room” inside the unit and decide how much of it you want to hear.

Or, you can try one of the pure effects like anger or phaser for something a

little different.

Each section, and each remote, can set how much of the effects engine

they would like in their mix. It allows each player can decide how much they

want to “wet out” the vocals.

The effects engine is connected to the mic inputs only. We did this because

most modeling amps, keyboards and electronic drums have their own built-

in effects. If you’ve ever heard one reverb put on top of another reverb, you

understand why we avoided mixing the two.

The SoleMix controls

The SoleMixTM controls found on each JamHub section

and on the SoleMix remote are easy to understand

and use once you know the basic layout and design of

a JamHub system.

First, look at your JamHub from the top. You’ll see

that there are 4 or 6 numbered sections that are also

color-coded. (the “R” section is reviewed below)

Typically you’ll want to use one section per musician.

If you are the guitar player, you connect your mic and

amp modeling device into section 1. Now everyone

in the band can use their SoleMix controls to balance

section 1’s level in their headphones by simply turning

up or down the control marked “1” on their SoleMix

section. The same applies to the “2”, “3” and “4” con-

trols in each section.

Don’t forget about the effects return knob. This allows

you to decide how much of the effects engine you

want to hear. The “dry” signal comes through each

person’s numbered SoleMix controls and the “wet”

signal comes through the “FX” control (under the headphone volume).

What’s cool about a JamHub is that once you know one section of the product, you know all the sections of the product.

Pretty easy, huh?

What’s up with the “R” section?

Here’s a little secret. The R section (for “rear” or “recording”) functions exactly the same as all the other SoleMix sections.

While it may look a little different, take a closer look. You’ll see that all the knobs are the same. The only difference is

how they are laid out on the JamHub.

Want to jam along with a recording of a song? Plug your MP3 player into the R section. Then each musician can decide

how much of the song to hear by turning up (or down) the R knob in their SoleMix section.

The R section is also designed for recording your jams. Just like one musician’s mix is different from another’s, a record-

ing mix is unique and you’ll want to use this section to make the right mix for recording. Can you use the “R” section for

another musician? Sure! Remember, it is simply another section of the JamHub.

To record, create a recording mix with the “R” section controls and connect to a computer or a portable recorder to the R

section and create a rehearsal recording. Make sure whoever you want in charge of the recorded mix is also plugged into

section 1. Read on to nd out why.

Left Brain:

The stereo effects engine is coupled to a set of 24-bit

48kHz audio codecs to ensure great sound quality. The

effects engine has 16 preset algorithms which cover all

of your basic needs and a few unusual effects thrown

in for fun. The codecs are wide bandwidth (100dB) and

low noise (s/n of 105dB).

Right Brain:

The types of effects cover a variety of options and each

musician can use the FX knob to control how much, or

how little, of the effects they want to hear.

Left Brain:

This switch takes the output of the R section and redi-

rects it to section 1 headphone jack. When the switch

is in the 1 position, the SoleMixTM output for section 1

is sent to the headphone jack of section 1. When the

switch is in the R position, the SoleMix output set in the

R section is sent to both the R section headphone jack

and the headphone jack in section 1.

Right Brain:

If you’re in charge of the recording mix, you need to

hear your mix for playing and the mix for recording.

To do this, you can disconnect your headphones from

your section’s headphone jack and plug them into the

R section’s headphone jack to hear the recording mix.

Or, make section 1 your mix, leave your headphones

plugged into section 1, and use the 1-R switch to quick-

ly alternate between your mix and the recording mix.

A more detailed review of setting trim controls

A simple analogy for trim and headroom

Let’s think of music as a person bouncing up and down on a trampoline. They can bounce a small amount or a large

amount. This is “dynamics.” Sometimes we bounce low, sometimes high. Most musicians are always changing the

“bounce” because most songs have both soft parts and loud parts.

Now let’s move that trampoline into a room with a ceiling. Ever heard of the term “headroom?” Well, headroom is the

distance between our head and the ceiling in our trampoline room. The ceiling isn’t moving, but we can raise and lower

the trampoline to give us more headroom, right? If our music is not very dynamic, that is our bounces are small, we

need less headroom. If some of our bounces are big, we’d better make sure the trampoline is far enough below the

ceiling that when we bounce hard we don’t hit our head and run out of headroom.

So how do we move the trampoline up or down? With the “trim” control. The trim control sets the trampoline higher or

lower. We can see how close we are getting to the ceiling by watching the LEDs: green = ok, yellow/orange = getting

close, red = bumping our heads.

Clipping is the term engineers use to describe when the amp is out of room (when our heads are bumping on the

ceiling). It describes what’s happening to the electrical signal. Our ears perceive clipping when we hear a sound that

has been distorted or compressed. With a guitar, distortion can sound good, but with vocals it usually does not sound good.

Signal to noise is the ratio of good stuff to bad stuff in your system. Signal is music. Noise is stuff you don’t want. If

we don’t get the trim set right, then the electronics noise that is in the atmosphere will start to be as loud as the music.

Think of the noise as the oor in our trampoline room. We want to be as far off the oor as possible, so we can really

bounce high. If the trampoline is too close to the oor, we’ll limit the power in our jumps because our feet will

When setting up your trim levels, there are a few things to keep in mind. First, leave plenty of headroom so that as

you get going you won’t get distortion from the system. Ideally, when you set the trim control, you should be playing at

the loudest volume. For example, a singer should not whisper in the mic to set the trim control, but sing as loud as

possible. If they whisper, they will set the trim (trampoline height) too high and run out of headroom the rst time they

yell “HEY”. Conversely, if they yell too loudly in the mic, the trim control will be set too low. Then when our singer

whispers, we won’t hear her above the rest of the instruments.

If you’re setting the trim for an instrument, leave room for solos. Your solo volume should be solid green with a little

yellow in the LED. Then turn yourself down a bit with your device’s foot pedal or a volume control. That will leave room

for you to jump to the top of the mix when it’s time for a solo.

For a vocal mic, you can simply move away from the mic, or “back off” the mic, to lower the volume. You see the pros

do this all the time. It’s a great technique to know and is easy to learn, especially with a JamHub silent rehearsal studio.

We hope this section helped with the mystery of setting trim control. Over the years we’ve heard some crazy things about

trim controls like, “always set it to 9:00” or “keep it as low as possible” or “set all trims the same” and worse. The truth

is, there is no “magic setting.” Every mic, instrument and piece of gear is different and needs its own unique setting. And

even if your band has the exact same mic for two singers, their individual voices are different. So they’ll need their own

unique trim settings. Just follow the LED’s guidance, watch the trim levels throughout the jam and you will be ne.

Additional GreenRoom and TourBus Features: Phantom Power

The GreenRoom and TourBus models both provide +48V phantom power for condenser mics. To turn it on, simply push

the button found on the back of the unit and the red +48V LED will illuminate red. You may hear a little static as it turns

on. This is normal and will go away after a second. What if only one person uses a condenser mic? No problem. Phan-

tom power is for condenser mics, yet won’t damage dynamic mics. Check out the Wikipedia article on how phantom

power works if you want to learn more: http://en.wikipedia.org/wiki/Phantom_power.

For instrument connections please use a stereo cable or the

included mono-to-stereo adapter.

Left Brain:

As with other equipment (mixers, recording interfaces,

some old tube amps, etc.) getting the trim right matters.

So we’ve simplied things by using a familiar structure:

green = signal, yellow = warning, red = clipping. We

believe it’s important for you to understand gain

structure completely so read below. It’s applicable to

nearly every piece of music gear you’ll own.

Right Brain:

Read below, this is just good stuff to know for

recording, live sound and getting great sound into and

out of your JamHub silent rehearsal studio. When in

doubt, red means stop (or turn down in the case of

the JamHub®).

Metronome

Let’s go through the Metronome functions. Hit the left most soft key below “Met”.

Now you can access these functions:

BPM=100 – This is the default tempo. You can change the tempo by pressing the soft keys under the BPM indicator.

The + key will increase the tempo and the – key will decrease the tempo. The tempo range is 30 BPM to

240 BPM (just for you crazy speed metal bands). If you hold the button down, the BPM advances faster.

Or click the button to change the BPM one increment at a time.

4/4 – This is the type of beat. You can change it to another type by hitting the “More” key. We’ll go into this in

detail below.

More – This key is where you can change the beat type or you can tap in a tempo.

Tap – This button allows you to tap the tempo. Simply tap in a tempo by pressing the button in time to the

music and the JamHub metronome follows your lead and displays the current BPM. Hit the Esc button to

return to the Met main menu where you can ne tune the BPM using the + and – key.

Type – Hitting this key changes the beat type. There are 9 types of tempos in the JamHub metronome: 1/4,

2/4, 3/4, 4/4, 5/4(23), 5/4(32), 7/8(223), 7/8(232) and 7/8(322) where the numbers in the parenthesis

disclose the accent beats locations. Keep hitting Type to scroll through the options.

Esc – Takes you back to the prior menu.

Utility

There are three functions in the Util menu: Format SD Card, Show Capacity and LCD Contrast. You can switch between

them by using the + and – keys. Hit OK to enter the selected function or Esc to exit.

Format SD Card – Use this function to rewrite an SD memory card that is unformatted or has been damaged.

Formatting will overwrite all data on the card and in the process may x a card that has been

damaged by a cell phone or magnet. Some damage is irreparable, but the JamHub will do it’s

best to x the card. Hit OK to reformat the card or Esc to leave the Util menu.

Show Capacity – This function shows how much room is left on the SD card in Gigabytes and percentage used.

LCD Contrast – Hit the + and – key to change the contrast level of the LCD.

Additional TourBus Features: Recording Functions

The JamHub® TourBus model has the ability to record your jam sessions directly onto a removable Secure Digital (SD)

RAM card. Once you’re done jamming, you can play the recording back right from the TourBus, or simply take the SD

RAM card to your computer and move the les for sharing and reviewing with the band (or others). TourBus recordings

are stereo and written as .WAV les at CD quality audio (16-bit 44.1kHz).

There are just a few things you need to know about the recording capability of the TourBus to get started. First, the R

section’s SoleMixTM controls are where you’ll create the mix for recording. If the person who’s going to manage the

recorded mix is also one of the musicians, they should connect their headphones into section 1 and use the 1–R switch to

quickly ip back and forth between their own mix and the recording mix. See the 1–R switch section on page 13 for more

details.

Menu Structure

and Soft Keys

The soft keys are software dependent. That

is, their functions change as you are using

JamHub’s recording capabilities. This is similar

to soft keys on your cell phone. Just watch the

LCD for clues as to what the keys do.

Transport (recording) functions:

The transport functions are designed like

those you’ve probably used before with a few

special capabilities. Let’s go through them

one at a time.

Rewind key: Hit once and the device

rewinds the current song at 5 seconds

per second playing 1 second of audio as it

rewinds. Double click the button and the

device rewinds at a fast speed (10 times

faster). Triple click the button and it takes

you to the beginning of the current song.

Triple click within the rst 3 seconds of a

song and you will be taken to the prior song.

Fast Forward key: Hit once and the

device advances through the current song

at 5 seconds per second playing 1 second of

audio as it advances. Double click the button

and the device advances at a fast speed (10 times faster). Triple click the button and it takes you to the next song.

Stop: This key stops the play, recording, fast forward and rewind functions.

Play: This key is used for playback of what’s been recorded.

Record: This key is used to arm the JamHub to record.

When you hit the record key once, you’ll see the button’s outer ring starts to blink red. This means the JamHub is ready

to record. Hit the Record key again and you’ll see the outer ring changes to solid red. This tells you that the JamHub is

recording. To turn on the metronome during recording, before hitting the record button a second time, hit the right most

soft button to turn on, or off, the metronome. Hit the Stop button to stop the recording process. The LED will turn off

indicating that the JamHub is no longer armed for recording.

When you hit the Stop button your TourBus will ask you if you want to keep the recording. Hit the soft key button under

the word “YES” to keep the le and hit the “NO” soft key to discard the recording. Note, there is no “undo” function.

When you are recording you will see “New” over the third soft key button. To start a new song le, simply hit “New” and

the TourBus will save your existing recording and start a new le. This allows you to have one song per le which helps

you nd songs after a jam. Having many small les is easier to manage than having one large le to listen through, so

use this button often. Also, after the jam, you can use a computer to rename the les for easier playback.

The red ring around the Record button is designed to be viewable from a distance. Simply look over at the JamHub

while you’re playing to know if it’s recording your jam. If there is a solid red light, you’re recording. If the light is blinking

or off, you’re not recording.

Left Brain:

Recording to the built-in recorder creates a stereo

recording with a bit depth of 16-bit and a sample rate

of 44.1kHz, known as “CD Quality” recording. Today’s

studio standards are around 24bit/96kHz (some go up

to 192kHz). The JamHub® is a very high quality “sketch

pad” for recording. A JamHub is not the right piece of

gear for creating your next album. A studio with a great

engineer is the right place for that. But using a JamHub

to get the songs right and tight, is a great way to

prepare your band for the studio.

Right Brain:

The JamHub records a stereo mix that is the same

quality as a CD. If you’re into creating music you realize

that songs, not sample rates, equal success. So focus

on writing great songs and practice them using your

JamHub silent rehearsal studio. Once you and the

band have the songs where you want them, you’re

ready to head to the recording studio and, with the

help of a great recording engineer, build an album

you’ll be proud of.

FAQs

An updated list of FAQs can be found on our website www.JamHub.com and there are helpful “how to” videos on our

YouTube channel www.YouTube.com/HubHed. For help with “not so frequently asked” questions, come to the JamHub®

community section of our website where there are musicians, engineers and tech support people answering questions

that have come up since we printed the manual.

No questions? Great, we’ve done a good job with the manual, but please come by our community. Who knows, maybe

you can help someone else with their JamHub.

Q: Can I use a JamHub with acoustic drums?

A: Yes! In fact, reheasals still sound clear and controlled. Just hang a microphone or two above the drum kit and plug

them into the JamHub. Or, use a small mixer and three microphones to create a stereo drum sound and connect that

mix to your JamHub. We recommend a microphone over the snare, one over the toms/ride and a kick drum. Pan the

two area microphones left and right, put the kick pan in the center and send that stereo mix into one of the JamHub

sections.

Q: If I use acoustic drums, will the JamHub make them quiet?

A: No. You’ll still have to deal with loud drums, but you can still keep the overall volume lower if there isn’t a loud bass

amp, guitar amp(s), keyboard amp and PA speakers. While it isn’t as quiet as electronic drums, you can still prevent

that next level of volume that comes with amps competing with each other in a room.

Q: How do I use an acoustic guitar with a JamHub?

A: Does it have a pickup? If no, put a microphone in front of the guitar and plug the microphone into an open microphone

input on the JamHub studio.

A: Does it have a pickup? If yes, and you want to go direct, grab a mono-to-stereo jack and plug it into the guitar end

of your stereo cable. You might nd that with one of the new “for acoustics” Direct Inject (DI) boxes or oor pedals,

that you like the sound and control of the acoustic better. There are a lot of engineering reasons for this (impedance

matching is the biggest of them) and that’s why DI boxes are used by the pros. If you’re going to play an acoustic,

you’re going to need a DI box someday.

Q: What instruments do not work with a JamHub?

A: We don’t know of any yet. There may be some out there, but we haven’t found them. Some companies have dedicated

their existence to creating instruments that can be played anywhere and anytime ... some even have an electronic

accordion line (not just one model, but an entire line!!!). Horn players can use silent practice inserts and cases to quiet

horns and create a headphone signal that you can send to your JamHub. Guitars, bass, drums, hand percussion,

keyboards, accordions, wind instruments, even a theremine will work! Just look for a headphone jack on the gear and

you’re ready to start jamming quietly with your JamHub studio.

Q: Do you have any tips for new users?

A: Yes. Since we invented them, and have played a lot of hours on them, we know a lot about how to make it easy to get

started. Here are our top tips:

1. Use good TRS (Stereo) cables and plug the cable going to the JamHub instrument jack directly into your

headphone output on your modeling amp, keyboard or electronic drums.

2. Get headphone cable extensions so you can move around as much as you want.

3. Use good headphones for good listening. The JamHub is acoustically transparent. It won’t change your sound.

So if your headphones lack quality, the JamHub can’t x it.

4. Get a microphone for each player, even if you don’t sing. Once you put on the headphones, it’s easier to

communicate if everyone has a microphone to speak into.

5. Guitarists: a modeling amp with a foot pedal allows you to control the volume of your sound so you can turn up

for leads. Keyboard player: use your instrument’s volume control to do the same.

6. Turn down (off) any input trim controls that are not being used to minimize the outside noise.
