INTRO
Congratulations and welcome to the Revv family! Thank you for trusting
Revv Amplification with such an important part of your musical endeavors.
Enjoy tone, durability, and ease of use designed to inspire.
Please note that this manual applies to both our Dynamis head & combo
amplifiers.They feature the same tone & controls - the only difference is in
setup & safety instructions given the combos have built in speaker(s).The
short version is to leave the speaker plugged into your combo, & never
turn on your head without using the right cabinet.

safety instructions & warnings
Please read, understand and follow all safety instructions in this manual,
as well as those on the rear panel of the amplifier. These instructions and
warnings must be followed for your safety, and also to ensure that the am-
plifier will serve you for many years. Please use common sense when
operating, this instrument is designed for electric guitar amplification, and
should only be used with electric guitar signals.
• Do not store or operate the amplifier in
damp/wet areas.
• Do not keep items that contain liquid
on or near the amplifier
• Allow for 4-6 inches of space around
the unit when operating. This unit
produces heat and should be kept
away from flammable items/objects.
• Do not expose the amplifier to high
temperature, keep away from radiators
or heat producing/supplying items.
• Be sure to connect to an AC power
supply that meets the power supply
specifications listed on the rear of the
unit.
• Do not use an AC power cord that is
damaged, has been pinched or is miss-
ing prongs.
• This amplifier must be properly
grounded to local standards when
being operated. Do not use 2 pole
extension or power cords to supply
power to this amplifier.
• Remove the AC power cord from the
amplifier when changing tubes, fuses
or when moving the amplifier. Always
replace fuses with the correct type
and rating. Always remove AC power
cord when removing chassis.
• The AC power cord should be
removed from the outlet when left
unused for long periods or when there
is risk of electrical storms.
• No user serviceable parts inside, all
service should be done by qualified
personnel only.
• Always make certain the proper load
is connected to the amplifier before
operating. Always make connections
to the amplifier with the power off.
• Your amplifier is designed to produce
high volume/sound pressure levels.
Long term exposure to these levels
can damage your hearing. Please use
hearing protection when exposed to
these levels for extended periods to
prevent loss of hearing or hearing
damage.
• Keep away from children.

set up & power up
Only keep your Revv in a dry place that keeps 6” of space between the
rear and any other objects. Tubes produce heat, and anything flammable
should be kept away.
First,make sure that the power and standby switches are in the off (down)
positions. Next, connect the AC power cord to the amplifier Mains con-
nector on the rear of the amplifier - then to an AC outlet. At this point, all
other peripherals can be connected to the amplifier as well: Foot Switch,
FX Loop, Guitar, and cable
Note: A high quality, shielded instrument cable is recommended for guitar
input as well as FX loop connections to prevent unwanted noise.
Once all your connections are made, move the power switch to the On
position and give the tubes at least one minute to warm up. Now is a great
time to begin setting all controls while we wait. We recommend setting
the master volume, channel level, and gain controls to the lowest setting
or zero (fully counterclockwise) and all treble,mid and bass controls to the
12 o’clock positions to begin. Now set the standby switch to the Revv (up)
position and you are ready start!
Note: Upon power up, you will notice that all LED’s light up for a couple
seconds and then only the Channel 1 LED remains lit.This is normal as the
amp does a start up sequence at power up, then arms channel one to
begin.

Front Panel Layout
Input
1/4” Instrument cable input.
Low Input
This input jack is to be used with guitars that have high output or active
pickups if you desire a cleaner sound & it provides the proper circuit to
keep the tone of the amp articulate & prevent unwanted compression &
noise. If you are finding the tone weak to your personal tastes - do not
hesitate to plug any guitar into the normal input to experiment with new
sounds. This operation is safe & will just hit the front end of the amp
harder if you are going for that sound.
Normal Input
This input jack is to be used with guitars that have passive pickups &
require high impedance for proper signal transfer.This jack is designed
to get the strongest signal from a passive pickup to the first tube stage.

Channel One (Clean)
Selected by: 1) pushing the designated front panel momentary toggle
switch up (LED turns blue), 2) footswitch button #1 or a footswitch
preset mode setting, 3) MIDI & CC commands.
Passive treble, middle, bass, & level controls with a wide range. Small
turns = large tonal change!
Bright changes top end response for a more sparkly tone. It is normally
best to choose the bright setting you prefer (on or off) & then dial treble
to taste. Also useful when switching between humbuckers & single coils!
Very warm & full-bodied clean channel. Takes pedals very well - or
decrease power to 7 watts for a more broken up sound with the Output
Power Switch. Channel output power is independent so you can use
this to control both tone & volume separately from the gain channel.
2.2

Revv Owner’s Manual - 8
Channel Two (Distortion)
Selected by: 1) pushing the designated front panel momentary toggle
switch up (LED turns red), 2) footswitch button #2 or a footswitch preset
mode setting, 3) MIDI & CC commands.
Gain, treble, mid, bass & level (volume) control knobs with a wide range
of operation - small adjustment = large tonal change!
The Dynamis contains 3 Dynamic Levels: crunch (green), open gain
(blue), & warm high saturation (red).This is an idea we borrowed from
the Generator’s Aggression Modes & applied to the Dynamis’ vintage
tones.You could easily cycle through these for crunch, rhythm & lead, or
find the mode you like the feel of best & always use it for all of your gain
tones!
2.3

Revv Owner’s Manual - 9
These dynamic levels can be cycled through both by repeatedly press-
ing the designated momentary toggle switch & by repeatedly pressing
the Channel #2 footswitch.
The amplifier has a midrange focus & to modify this you can either slight-
ly dial back the mid control or switch between the two Contour options
for a bright upper-mid focused sound (on) or a thick lower-mid focused
sound (off).
The Bright switch also controls Channel 2 (independently) & as above
can be set to taste to help you find your desired top end response.
As with Channel One, Channel Two has an independent 40 watt / 7 watt
Output Power Switch. 7w mode will help achieve satisfying sounds at
lower volume and/or give you the option of a tone featuring more power
amp saturation. All else being equal this will result in a more broken up
oldschool sound, compared against letting the preamp take care of
much of the gain in the higher headroom 40w mode.

Reverb, Level, & Decay Switches
The Dynamis includes a lush onboard reverb with 3 decay lengths.
These decay lengths & the level of the reverb are independently con-
trollable per channel using the front panel controls.
Upon startup, reverb is engaged with a short decay. To turn reverb on or
off, simply press the reverb toggle switch in the up position. The LED will
turn on or off depending on the setting.To cycle through different decay
options, simply press the toggle switch down towards the decay posi-
tion. The decay options are indicated by LED: short decay (off), medium
decay (blue), long decay (Red).
Note: These levels can be cycled through by holding footswitch button
#4. Reverb can be turned on & off entirely with a single momentary
press of button #4.

Standby & Power Switch
The Dynamis includes a lush onboard reverb with 3 decay lengths.
These decay lengths & the level of the reverb are independently con-
trollable per channel using the front panel controls.
Upon startup, reverb is engaged with a short decay. To turn reverb on or
off, simply press the reverb toggle switch in the up position. The LED will
turn on or off depending on the setting.To cycle through different decay
options, simply press the toggle switch down towards the decay posi-
tion. The decay options are indicated by LED: short decay (off), medium
decay (blue), long decay (Red).
Note: These levels can be cycled through by holding footswitch button
#4. Reverb can be turned on & off entirely with a single momentary
press of button #4.
The power & standby switches give the amp power from the mains, as
well as high voltage through the circuit. First turn on the power switch &
wait one minute to allow the tubes to warm up. Turn on the standby
switch to the Revv position once you are ready to play.
Note: NEVER power up the Dynamis Head without the proper speaker
load connected, or the Dynamis combo with the speaker disconnected!
Each channel reverb level control is independent & decay settings +
on/off states are retained for each as long as the amp is powered on.
Note: Reverb settings are also footswitch saveable options should the
foot controller be used in preset mode. See foot controller section of
this manual for more information.

Rear Panel Layout
Main Power Connection
When plugging the amplifier into the mains A/C wall receptacle, always
make sure the amplifier power & standby switches are in the off position.
The Required voltage & fuse ratings are marked on the amplifier, verify
that they are correct before plugging in.
Main & HT Fuses
The mains fuse & HT fuse are in place to protect you & your amplifier
from overload conditions. Always replace them with the same type &
rating only! Always unplug the amplifier from the mains before replacing
the fuses. Fuse requirements are marked on the rear panel of the amplifi-
er.

Bias Test Points
This amplifier is designed to allow the user to set the bias of the power
tubes without removing the chassis from the head shell.
Each pair of power tubes needs to be set according to the tubes being
used.
Power Tube Fault Fuses
The power tubes are fused in pairs. Should a power tube fail, the fuse will
blow & take the pair of power tubes out of service. This has the benefit
of protecting the amplifier, & also allows for continued playability, so as to
allow the user to finish the gig on the remaining pair. The volume & tone
will change but the show will go on.
Note: Should the amp be run with 2 power tubes removed from service
(bad or blown fuse), in order to achieve a tone more consistent with
normal 4 tube operation the amp should be run with an impedance
setting of half the speaker cabinet rating. For example, if the speaker
cabinet is 8 ohms, set the amplifier to 4 ohms, & if the speaker cabinet is
16 ohms, set the amplifier to 8 ohms.
3.2

Revv Owner’s Manual - 14
Impedance & SpeakerJacks
The amplifier must always be connected to a speaker cabinet or load
when it is powered up.This amplifier can be used with cabinets that
provide a load of 4, 8 & 16 ohms.
Note to combo users: The combo can only be used with external cabi-
nets of 4 or 8 ohms
Because the amplifier provides multiple speaker jacks, it can also power
2 cabinets directly from the amplifier, but the impedance will need to be
set correctly.
Most setups are simple, one cabinet plugged into the amp, set the
impedance to that marked on the cabinet & you’re ready to go! Howev-
er, when it comes to adding more cabinets to the rig, more care must be
taken to prevent damage. Most rigs will not utilize more than 2 cabinets
so we won’t go beyond 2 cabinets here.
3.3

Revv Owner’s Manual - 15
Some multi-cabinet head examples:
2 - 8 ohm cabinets would be run to the amplifier (one per speaker jack),
the correct impedance would be 4 ohms as they are being run in paral-
lel.
2 - 16 ohm cabinets would be run to the amplifier (one per speaker
jack), the correct impedance would be 8 ohms as they are being run in
parallel.
2 - 4 ohm cabinets cannot be run in parallel with this amplifier. This will
cause damage.
Note: No damage will result when running the amplifier set at a lower
impedance (Ex: 4 ohms) into a cabinet rated at a higher impedance (Ex:
8 Ohms). However the opposite will possibly cause damage to the
output transformer or other components & it is suggested that the
amplifier never be run into a lower load than what the amplifier is set to
when hooking up speakers in different configurations.
Some combo examples:
1 - 8 ohm cabinet AND the provided 8 ohm combo speaker: In this con-
figuration, plugging the provided speaker into one of the 4 ohm jacks &
the 8 ohm speaker cabinet into the other 4 ohm jack will provide the
perfect load to maintain the best possible tone & keep the amplifier safe
from harm. The 8 ohm jack MUST NOT be used!
2 - 8 ohm cabinets: In this configuration, one of the 8 ohm cabinets
would be plugged into a 4 ohm jack, & the other 8 ohm cabinet would
be plugged into the remaining 4 ohm jack. The provided speaker MUST
be disconnected from the 8 ohm jack, & the 8 ohm jack MUST NOT be
used.

Revv Owner’s Manual - 16
FX Loop Connections
The FX loop connections are to be hooked up to external pedals or
effects units.The Send level will supply the signal required & needs to
be set accordingly with the send level control.
1 - 8 ohm cabinet WITHOUT the provided 8 ohm combo speaker: In this
configuration, the provided speaker would be disconnected from the 8
ohm jack & the 8 ohm speaker cabinet would be plugged into that same
jack. The remaining 4 ohm speaker jacks MUST NOT be used. The pro-
vided speaker cannot be used in this configuration & must remain
disconnected.
1 - 4 ohm cabinet: In this configuration, only one 4 ohm speaker cabinet
can be used with this amplifier. The provided 8 ohm combo speaker
MUST NOT be used, the remaining 4 ohm and 8 ohm speaker jacks
must also NOT be used.
2 – 4 ohm cabinets cannot be run in parallel with this amplifier. This will
cause damage.

Revv Owner’s Manual - 17
MIDI Connections
Note: The Dynamis Combo does not include midi.
The MIDI IN connection is for external equipment connections when
your rig necessitates control of your Revv with third party gear.
Foot Switch Connection
This connection both powers your footswitch & allows it to control your
Revv.
Should the provided footswitch cable fail, any Ethernet cable can be
used. However, this cable sends data between the amplifier & footswitch
& if a lower quality cable is used incorrect switching or erratic behavior
may occur. A high quality cable is recommended, which can be provided
by Revv should you need a replacement.
Speaker Cab Lighting
Revv speaker cabinets each have an illuminated up logo which is pow-
ered from the cab lighting jack on Revv amplifiers. This is a 4 pin DIN jack
that should be connected to the 4 pin DIN jack of a Revv speaker cabinet
only. The logo will change colors in conjunction with the channel switch-
ing of your head.
Note: This jack can only be used with Revv speaker cabinets.
Solo Level Control
This knob sets the level of the Dynamis’ solo boost which is engaged
when pressing button #3 on the footswitch. You could also use this to
reduce volume.

Revv Owner’s Manual - 18
Serial Effects Loop
This effects loop is foot switchable, preset recallable, & MIDI + CC con-
trollable. It has also been given an On & Off control ability to have the
send level control & FX Loop jacks removed from the signal path entirely
- even though it was designed from the start to be as transparent as pos-
sible.Tube driven with the send output buffered at 900 ohms.
FX Loop On/Off
The amplifier’s footswitch (button #5 in control mode) is used to switch
the effects loop in & out of the signal path to make it easier to apply &
remove effects to the guitar signal on the fly.
If you do not use the footswitch, the FX loops will always default to an on
state.If the footswitch is plugged in - the FX loop defaults to off unless acti-
vated via the footswitch.
Midi will always be able to control FX loop state as well.
SEND Level Control
This effects loop has a Send Level control to make sure your effects
volume is optimal. Always make sure to check this knob if you are experi-
encing any overly loud, or quiet effects - or level issues of any kind.
If your effects start clipping - you are driving the loop too hard with this
control.

Revv Owner’s Manual - 19
Note: The level controls on each channel will also affect the send level
being sent from the effects loop - when one is set higher than the rest
you will find your signal changes when using that channel. Be sure to test
each channel & the send level coming from the effects loop. For this
reason it is normally preferable to set the level of your channels first then
adjust your effects loop send level.
FX Loop Hook up
First, you need to hook up your effects units to the amplifier. The send
jack will need to be connected to the input of the first (oronly) effects unit
in your chain. The out jack on the effects unit (or last pedal in your chain)
will then connect back to the return jack on the amp.
Adjust each channel’s level control to your liking & set your send level
control as above.
Note: If you hear no sound - your effects loop level control knob is proba-
bly set at zero, or your FX loop is disabled! Refer to the above on/off sec-
tion.

Tubes & Bias
Power Tubes
Our lower wattage amplifiers are designed with 6V6 tubes for the best
tonal & feel performance at a wide range of volumes.REVV-brand 6V6GT
tubes are always recommended when replacement is required.
Note: While we designed the amplifier to be easy to maintain, we advise
that all tubes be set up by a qualified service technician to prevent
damage to the amp from improper bias settings.
Preamp Tubes
This amplifier uses 12AX7 preamp tubes in tube positions V1 V2 V3, & V5.
A 12AT7 preamp tube is used in the V4 position for the FX Loop & only a
12AT7 tube should be used in this socket.
Preamp tubes do not need to be biased & usually have a long life unlike
power tubes, but it is possible for a preamp tube to become faulty at any
stage of its rated lifespan.
Power Tube Bias
The power tubes can be biased without taking the chassis out of the
wood head shell.You will need a voltmeter or digital multimeter set to the
lowest DC voltage range. (Make sure you refer to the meter’s user
manual).
Note: Use tubes that are matched! A matched quad is best but matched
pairs will also suffice.
