AM1
AUTOMATIC MIXER
OPERATORS MANUAL
WEAR PARTS: is product contains no wear parts.
QUICK START
If you’re setting up the AM1 automixer, but your life depends
on getting back to Twitter® feeds and Facebook® posts, then this
Quick Start is for you. It’s intended to get your audio working
quickly in slightly more than 140 characters.
Plug microphones into the Mic Inputs using standard XLR
mic cables. Condenser mics need the MIC +48V switch posi-
tion. Use the MIC +0V middle position for dynamic mics. Use
the WIRELSS MIC position when a wireless receiver output is
connected.
When using the USB Charge-Only port, connect charg-
ing MP3 player audio into AUX 1 or AUX 2. Other line-level
sources (e.g., DVD/CD) may also use AUX 1 or AUX 2. Use the
USB Charge-Only port for keeping the iPod’s battery charged
during playback.
Connect the Main Output XLR to your amplier or powered
loudspeaker and select the LINE switch position. If the Main
Output feeds a microphone input, select the MIC position.
Connect the computer’s USB port to the USB Audio jack.
Once the Windows® or Apple® operating system recognizes the
AM1 as a stereo I/O device, the rear green USB light illuminates.
Start with all the front panel gray knobs turned all the way
down – fully counterclockwise. One at a time for each mic, talk
very loudly with a microphone at an appropriate distance for the
application and adjust the corresponding front panel LEVEL
control so only the loudest speech just barely ickers the red
overload (OL) indicators. Once the input gains are set, the AM1
automatically controls the mic mix to avoid feedback. (You won’t
need to ride these controls.)
Sources with output volume controls (e.g., iPods) need to be
turned up most of the way to get the hottest signal, but without
making the AM1 overload lights ash.

Play audio from your computer’s audio software application
and select the Rane AM1 as the playback and/or recording de-
vice (See USB Audio later in this Manual). If the software oers
playback volume, turn it up all the way.
Turn on the amplier/loudspeaker and turn it up about
half way. Also turn the AM1 OUTPUT gray knob up until the
volume is appropriate for your application. Use the four gray Mix
knobs to adjust the relative volume of the sources.
If the system feeds back (that horrible squeal), something is
turned up too much. First try moving the mics farther from the
loudspeaker and/or pointing the mics and loudspeakers away
from each other. If this does not reduce feedback, don’t reach for
the black Mic Input knobs, instead turn down the gray Mic Mix
knob. While turning down the output or amplier may help,
this also turns down the iPod, CD or USB Audio, only hiding
the feedback problem.
If your system uses the AM1’s rear panel RAD Port, connect
a shielded CAT 5e cable (or better) from the AM1 to either the
wall plate RJ-45, or to a Rane HAL, EXP or Mongoose RAD
port. See the Rane RADX product for useful RJ-45 wall plates.
When cascading one or more AM2 automixers into the
AM1, be certain each Cascade In connection feeds a Cascade
Out. In a cascaded chain, the AM1 must be the last device
before the analog audio connection to the ampliers, powered
loudspeaker, or the digital RAD connection to a Rane HAL,
EXP or Mongoose RAD port. Only one AM1 can be included in
a cascaded system of AM1s and AM2s. And only the AM2 can
be cascaded into Halogen’s Gain-Sharing Auto Mixer and Room
Combine Processor DSP blocks.
Now you can tweet that your AM1 is working ne.

indicators warn of excessive signal levels.
2MIC MIX LEVEL control adjusts the volume of all mixed microhones, including all upstream microphones when cascading
additional mics from a Rane AM2 (sold separately). Signal and Overload indicators inform and warn.
3AUX 1 & AUX 2 MIX LEVEL controls alter the mix volume of the Aux 1 and Aux 2 inputs, respectively. Corresponding Signal
and Overload indicators ank each.
4USB MIX LEVEL control adjusts the mix volume of the USB audio received from a computer connected to the rear panel USB
Audio jack. Signal and Overload colors are reminiscent of holiday lights.
5Main OUTPUT LEVEL control adjusts the level of the mix exiting the XLR output and the RAD Port output. e Record
Output level is not aected by this control.
6PHONES SOURCE cue switch selects which audio is heard in the headphone outputs: the mix of all Mics, the Aux 1 input, the
Aux 2 input, the USB audio input, or the Main Output. is allows listening in headphones to any single input before turning
each up in the mix using the MIX controls, or listening to the main mix before turning it up in the PA for the world to hear.
7PHONES LEVEL control adjusts the volume of both the 3.5 mm and ¼" headphone jacks.
8PHONES include both 3.5 mm and ¼" headphone jacks for either size headphone plug.

REAR PANEL DESCRIPTION
1AC Power IEC input accepts electrons to power up the AM1. ough it is rst in this list, it’s best to connect it last.
2FAULT indicator lights when something goes awry.
LOCATE indicator ashes when toggled from the Mongoose Tracker or Halogen software. When using multiple AM1 devices in
a Rane Mongoose or HAL system, this uniquely identies a specic AM1.
USB indicator lights when a Windows or Apple operating system recognizes the AM1 as a stereo I/O sound card.
POWER indicator glows when owing electrons pass in and out of the AC Power IEC input.
3USB AUDIO connector allows simultaneous 16-bit, 48 kHz playback and recording via a computer. e AM1 registers as a
standard sound card with either Windows or Apple operating systems.
4CASCADE IN port permits adding up to 56 more microphones to the AM1’s 4 mic inputs using up to 7 Rane AM2 automixers,
sold separately. Use shielded Ethernet CAT 5e cable connected from the AM2’s Cascade Out.
5RAD PORT connects to either a Rane HAL or Mongoose Remote Audio Device port to transport the single-channel, Main Mix
of the AM1 to Rane’s expandable DSP or to a CobraNet network, respectively.
6CASCADE IN & RAD PORT status indicators prove that proper cable termination and device conguring has occurred when all
four indicators illuminate. If any of these are o or ashing, a conguration or wiring error is the culprit.
7MAIN OUTPUT XLR connector contains the main mix of all mics, Aux 1, Aux 2 and USB Audio input signals. e front panel
Output Level control adjusts the level exiting this jack.
MIC/LINE Output switch changes this Main XLR Output to mic-level, for feeding the output mix to a mic input device; or
line-level for feeding line-level input devices.
8RECORD Output RCA jacks contain the same audio mix as the Main Output. e signal is not aected by the Output Level
control.
9USB CHARGE-ONLY port powers and charges many USB devices such as iPods®.
0AUX INPUT 2 stereo 3.5 mm jack is internally monoed immediately and useful for connecting MP3 players of all kinds.
qAUX INPUT 1 dual RCA jacks are internally monoed immediately and enjoy being fed audio from CD, DVD, 8-Track tape
players, reel-to-reel machines, docking stations or iPhone®, iPod® or iPad® headphone jacks.
wMIC INPUTS 1 thru 4accept dynamic or condenser microphones, or the output of a wireless microphone receiver. ese inputs
are optimized for speech and have a xed 80 Hz low-cut and 7 kHz high-cut lter. Both lters are 2nd-order Butterworth lters.
e3-position switches support:
MIC +48V phantom power Mic position for condenser mics.
MIC +0V Mic position for dynamic mics.
WIRELESS MIC position intended for wireless mic receiver outputs.

CONNECTION
Connect the AC power cord last to avoid loudspeakers hurting
your sensitive ears.
MIC INPUTS
e four mic jacks are balanced XLR inputs. Unbalanced mics
or wiring can also be used with their inherent lower quality and
higher potential for hum and noise. Standard microphone cable
with a two-conductor twisted pair plus a shield is best. Rane
follows the AES recommended practice of pin 2 positive (hot),
pin 3 negative, and pin 1 to shield. If your microphone is unbal-
anced (only two conductors), see the Sound System Interconnec-
tion RaneNote elsewhere in this manual or on Rane’s website for
the proper cable to use. Or better yet, get a balanced mic.
For condenser microphones which require phantom power,
use the MIC +48V switch position. Dynamic mics use the cen-
ter, MIC +0V position. When connecting a wireless microphone
receiver, use the WIRELESS MIC position.
AUX INPUTS
e two Aux inputs accept line-level audio for connection to
CD/DVD players and portable MP3 players utilizing the USB
Charge-Only port or its external charger.
While the physical ¼" and 3.5 mm jacks are both stereo, the
internal audio on both Aux inputs is immediately monoed since
the AM1 Mix is mono.
USB CHARGE-ONLY PORT
e USB Charge-Only port supplies 5 volts DC at up to 500
mA to charge iPods® and many other USB-powered devices. e
3.5 mm Aux 2 input is optimized to accept audio from devices
plugged in to the USB Charge-Only port.
RECORD OUTPUT
e RCA line-level outputs are unbalanced. Both RCA jacks
contain the same mono mix of the Mic, Aux, and USB Audio
inputs.
MAIN OUTPUT
e Main Output is a mono balanced XLR jack. Connect the
Main Output XLR using mic cable to your amplier or powered
loudspeaker and select the LINE position on the adjacent switch.
If the Main Output feeds a microphone snake or mic input,
select the MIC switch position.
USB AUDIO PORT
Connect a USB cable from this port to the computer’s USB port.
Once the operating system recognizes the AM1 as a stereo input
and output “sound card,” the rear panel USB indicator lights.
e AM1 can simultaneously playback and record via a com-
puter using this USB audio port.
RAD PORT
If your audio system delivers the AM1’s Main Output audio
mix using Rane’s digital audio transport technology exiting the
RAD Port, connect a shielded Ethernet patch cable to the RAD
Port. When the Rane Mongoose or HAL at the other end of
this connection recognizes the AM1’s RAD Port, audio nirvana
is achieved and all four adjacent RAD Port Status indicators
illuminate.
CASCADE IN
Connect a shielded Ethernet patch cable from the CASCADE
IN port to a Rane AM2’s CASCADE OUT port to add more
mics to the mic mix of an AM1. All four CASCADE IN Status
Indicators illuminate when the two devices recognize each other.
Connect up to seven Rane AM2 Automixers to add up to 56
more mics. Be certain to connect CASCADE OUT to CAS-
CADE IN throughout – otherwise, nirvana won’t be achieved.
Note: Only one AM1 Automixer is permitted in a cascaded
system. When cascading mixers, the AM1 must be the device
that feeds the Mongoose or HAL. In other words, the AM1
RAD Port wires to the Mongoose or HAL, and up to seven
AM2 mixers chain together into the AM1’s CASCADE IN. See
the illustration below.

MIC INPUTS
e rear panel three-position switch sets the appropriate gain for
condenser, dynamic and wireless microphones as well as select-
ing phantom power for condenser microphones. e Mic Inputs
are automatically mixed using a gain-sharing algorithm. Set
the inputs using the black knobs so they do not (or rarely) clip.
en, sit back and relax. If you’ve already set up the inputs and
someone starts talking louder/closer than you expected, feel free
to turn them down a little.
e green Signal indicators should easily light for soft talk-
ers even at relatively low Level settings. e Overload indicator
should light only occasionally for only the loudest talkers.
e gray Mic Mix knob adjusts the level of the automatic
mix of all Mic Inputs. Use it to change the mix of all the Mics
relative to the Aux 1, Aux 2 and USB Audio Line Inputs. Even
when multiple Rane AM2 Automixers are cascaded into an AM1
providing additional microphones, the Mic Mix knob on the
AM1 still adjusts the overall mix of all microphones – up to 60
mics when using seven AM2s. e Overload indicator adjacent
to the Mic Mix knob indicates that the mix of all mics is getting
too loud for the internal circuitry. It can light occasionally, but
only during the loudest talking.
Since these Mic Inputs and their underlying gain-sharing au-
tomix algorithm are designed and optimized for speech signals,
do not use these Inputs with non-speech audio signals such as
musical instruments or CD/DVD.
AUX INPUTS
e 3.5 mm Aux 2 input jack is optimized for use with devices
connected to the adjacent USB Charge-Only port. For other
audio sources , use the Aux 1 RCA jacks. Since the AM1 mix is
mono, audio at these two stereo inputs is monoed upon entering
the AM1. Adjust the front panel Aux Level controls for Aux 1
and Aux 2 to set the relative mix of these sources. e Overload
indicators light when the incoming audio is getting too loud.
Only the very loudest audio sources should occasionally light the
Overload indicator.
If you’re using an iPod® or other aux/line source that allows
output volume adjustments, turn the volume up as far as possible
without lighting the Overload indicator too often.
MIXING
e Mic Inputs are automatically mixed. Use the four gray Mix
knobs to adjust the relative volume of the four inputs: Mic Mix,
Aux 1, Aux 2 and USB Audio from the PC. e red overload
indicators should light only when the loudest source sounds are
running at full-tilt boogie.
OUTPUTS
All the AM1 audio outputs, digital and analog, contain a mono
mix of the automatically mixed Mics and manually mixed Line
Inputs from the four gray Mix knobs.
RECORD OUTPUT
e level or volume of the Record Output is not altered by the
AM1’s front panel Output level control. is permits consistent
recording levels on your favorite recording device, while adjust-
ing the volume in the room / PA system.
MAIN OUTPUT
e front panel Output Level control adjusts the level of this
output.
HEADPHONE AND CUEING
Plug in headphones and adjust the Phones Level knob to a com-
fortable volume. All headphone audio is mono – just like all the
other AM1 outputs.
e Source knob allows cueing each mix source indepen-
dently. is allows verication that a source is working properly
before bringing it into the mix.
With the Source set to Output, the entire mix is heard. Use
the four gray Mix knobs to adjust the relative volume of each
source. Select Mic Mix to hear the automatic mix of all micro-
phones in the system. Select Aux 1, Aux 2 or USB to hear each
of these inputs individually.
Use only one of the headphone jacks at a time.

CASCADE IN PORT
e Cascade Input allows more mics to be added to the gain-
sharing mic mix algorithm of the AM1’s four Mic Inputs. When
a shielded Ethernet patch cable fed from an AM2 is connected
here, all cascaded AM2 microphones are automatically added to
the automatic Mic Mix of the AM1. (US Patent Pending.)
Cascade audio is 24-bit, 48 kHz, xed-point for the curious
audio nerd.
To add more microphones to your system, use a Ethernet
patch cable to connect an AM2 CASCADE OUT port to the
AM1 CASCADE IN port. Doing so allows all 12 mixed micro-
phones (eight AM2 + four AM1) to be heard at the AM1’s Main,
Record, USB Audio and RAD Port Outputs.
When all four Cascade Status indicators light, this means
the cable is wired properly. If any of the Status indicators are
ashing, the cable is not wired properly or damaged. In this case,
perhaps an Ethernet crossover cable was accidentally connected,
or the cable crimp has an error.
We recommend using shielded twisted-pair for the best EMI
performance.
CASCADE IN Status indicators are dened below:
AUDIO TX LED – lights when the AM1’s audio is successfully
transmitted to, and received by, the AM2. If this is o, check
the cable.
AUDIO RX LED – lights when the connected AM2 successfully
sends audio which also proves this twist in the cable is correct.
COMM LED – lights green when the AM2’s Cascade Out is
properly communicating with the AM1 and proves that the
twisted pair for Comm in the cable is good. If this indicator is
o, the cable is not a happy camper.
POWER LED – is always on when the AM1 is powered. If the
AM1 is powered and this is o, make sure the power twisted
pair in the connected cable is not shorted.
RAD PORT
e RAD Port contains a Rane-specic digital audio transport
protocol allowing audio delivery to either a Rane HAL, EXP or
Mongoose RAD port (each sold separately). e audio exiting
the RAD Port contains the main mix and is attenuated by the
AM1’s front panel Output Level control. is port can only be
used to connect to a Rane Mongoose or HAL.
For inquisitive technophiles, RAD Port audio is 24-bit,
48kHz, xed-point.
RAD PORT Status indicators are dened below:
AUDIO TX LED – lights green when communications with the
Mongoose or HAL has been established and is receiving the
AM1’s Tx audio. If this indicator is o, either the cable is bad,
or there is a communications error between the Mongoose or
HAL and AM1 RAD Port (see COMM LED below).
AUDIO RX LED – lights green when the RAD Port successfully
receives audio from the Mongoose or HAL. If this indicator is
o, you may have a bad cable, or the Mongoose or HAL at the
other end of the cable is not powered or connected.
COMM LED – lights green when communication is established
between the Mongoose or HAL and the AM1. is indicator
turns o if the RAD Port cannot communcate with the
Mongoose or HAL for some reason – most likely due to a
faulty cable.
POWER LED – lights green when the RAD Port is receiving 24
volt power from the Mongoose or HAL. is also indicates
that the twisted pair for power within the cable is wired and
crimped properly. If the Power LED is o and the other end
of the cable is plugged into a powered Mongoose or HAL,
there is a problem with the cable.

Manual-7
USB AUDIO I/O
Since the AM1 appears as a standard Windows or Mac stereo
playback and record device, you can simultaneously record the
AM1 Main Mix and playback audio via the USB. is makes
many popular audio software programs instantly compatible
with the AM1. Once the computer’s operating system nishes
registering the AM1 via USB, the rear panel USB indicator
lights. e AM1 always registers as a 16-bit, 48 kHz device.
Most audio programs work after setting the AM1 as a default
device, but a few programs may need their preferences manually
set to play or record at 16-bit, 48 kHz.
Play audio from your computer’s audio software applica-
tion and select the Rane AM1 as the playback and/or recording
device. If your audio software oers a playback volume control,
turn it up most or all of the way, but without ashing the front
panel USB input Overload indicator too much. e front panel
USB Mix Level knob adjusts the mix volume of the incoming
USB audio.
WINDOWS OPERATION
When Windows detects the AM1 it automatically sets it as the
default Recording and Playback device. With Windows XP® and
Vista®, any audio applications currently running will continue to
use the previously selected default device. Restart the application
to make it use the AM1 for recording or playback. Windows7®
and 8® automatically switch a running application to the newly
connected AM1. To avoid surprises, we recommend turning the
USB Level down while connecting.
Remember that Windows likes to play dierent bleeps and
bloops when updates install, devices are plugged in and un-
plugged, or other operating system events happen. If you do
not want these sounds played into your mix, turn o Windows
system sounds. is can be found in:
Start -> Control Panel -> Sound -> Sounds (tab) -> Sound Scheme -> No Sounds.
Finding the audio properties and devices in Windows varies

MACINTOSH OPERATION
When OSX® detects the AM1, it adds it to the list of audio

select the device you want to use. Other applications only use
the device specied as the OSX default. We recommend that you
set the default audio input and output device to the AM1 before
starting the application you want to use.

AM1 and AM2 Common Features
e Rane AM1 and AM2 may be each be used on their own as a
standalone mixer, or add more gain-shared mics using up to seven
AM2 Automixers.
Each of the XLR Mic Inputs oers front panel input Level
controls feeding a gain-sharing automatic mixer. e AM1 has
four Mic Inputs, the AM2 has eight. Rear panel, 3-position
switches for each Mic Input support dynamic mics (no phantom
power), condenser mics (48 V), or wireless receiver outputs (+12
dBV max). A front panel Mic Mix Level control adjusts the vol-
ume of all automixed mics.
e Mic Inputs are optimized for automixing speech. ey
have a xed 80 Hz to 7 kHz bandpass lter (2nd-order Butter-
worth) to provide the best voice-only automatic mixing using a
gain-sharing algorithm.
Signal and Overload indicators monitor every Input Level
control and the Output Mix Level. Indicators ank each corre-
sponding Level control.
e XLR Main Output can be set to Mic- or Line-level to feed
a mic snake or a +20 dBu max balanced input. e front panel
Output Level control aects the XLR Output and the RAD Port
output.
AM2 mixers may be cascaded, but only one AM1 may be
used, and it must be the nal unit in a chain of no more than
eight AMs. Simply connect Cascade OUT ports to Cascade IN
ports and the nal Output level on the last AM controls the main
mono output mix.
Use the RAD Port to transport the main output mix digitally
via shielded CAT 5e to either a Rane HAL’s RAD Port for further
signal processing and control, or to a Mongoose for potential
routing to a CobraNet network.
Both the RAD and the Cascade IN port have status indicators
to aid setup and troubleshooting. Rear panel Fault, Locate, USB
and Power indicators inform head-scratchers of device errors, the
AM’s physical location, positive USB audio device OS registration
and AC power status. Duplicate Locate and Power indicators are
on the front and rear.
Universal IEC power on the rear supports 100 to 240 VAC
and 50/60 Hz.
AM1 Unique Features
e Rane AM1 is part gain-sharing automatic mic mixer, part
manual line mixer, part USB audio I/O device, and simultane-
ously a Rane RAD. Use it as a standalone mic/line mixer with
up to four mics, or add more gain-shared mics using up to seven
AM2 Automixers for up to 60 gain-shared mics.
ree manually-mixed audio inputs provide a simple user
interface and installation. e Aux 1 Input dual RCA and Aux 2
3.5 mm jacks are independently mono’ed, each with a front panel
Level control. A dedicated USB Charge port adjacent to Aux 2
provides power to USB devices such as iPods® or other USB-pow-
ered devices. e separate orange USB Audio Input also oers a
front panel Level control for the 16-bit, 48 kHz digital audio that
is mono’ed immediately upon entry.
e AM1 appears in Windows and Apple OS X computers
as a standard USB Audio Device, immediately compatible with
dozens of audio recording and playback audio applications. e
AM1 registers with the OS as a 16-bit 48 kHz device for both
incoming and outgoing audio. e USB Audio port doubles as a
rmware update port if future updates become available.
e front panel Output Level control aects the XLR Output
and the RAD Port output. e analog RECORD RCA Outputs
and the digital USB Audio output are both mono, pre-Output
Level, containing the same mix as the Main Output.
A front panel pre-Output Selector permits headphone cueing
so users can verify input and output operation before bringing
new sources into the live Output mix. Both ¼" & 3.5 mm head-
phone jacks with a Level control are provided.
AM2 Unique Features
e Rane AM2 is both an 8 channel, gain-sharing automatic mic
mixer and simultaneously a Rane RAD. Use it as a standalone
mic-only mixer, or add more gain-shared mics using up to seven
additional AM2 Automixers for up to 64 gain-shared mics.
When an AM2 is used standalone, both the XLR Output
and the RAD Port output audio are aected by the front panel
Output Level control. When the AM2’s Cascade Output feeds a
downstream Rane AM1 or AM2, the front panel Output Level
control only aects the XLR Output.
e USB port is solely used as a rmware update port if future
updates are needed.

RADs
An entire family of RAD models interface with HAL or Mon-
goose Systems for digital conversion at the wall. Each converts
analog audio to and/or from 24-bit, 48 kHz digital audio.
Shielded CAT 5e (or better) cable and termination transport four
digital audio channels – two channels each direction – as well as
power, ground and a communications channel, with status indica-
tors at each RAD, host unit, and host software. All RADs are
both “location-aware” and hot-swappable with 500-foot homerun
connections (66% farther than Ethernet). Most RADs mount in
standard US electrical boxes, and are available in white, ivory, or
black, with a matched Decora™ plate cover included.
Mongoose
Mongoose can replace the analog mic and line level portions of an
audio system with digitized audio over shielded CAT 5e cable (or
better). Mongoose can be used with or without CobraNet.
e Mongoose’s 32-by-32 digital audio matrix router receives
its rst 16 audio channels from up to eight RADs via the eight
rear panel 8P8C (RJ-45) Remote Audio Device ports. e second
16 matrix input channels come from two eight-channel CobraNet
receive (Rx) Bundles via standard CobraNet Primary and Second-
ary/backup ports. e 32 matrix router outputs transmit 16
channels to eight RADs and 16 more channels to two CobraNet
transmit (Tx) Bundles. Mic inputs can be greatly increased by
connecting a RAD output from an AM1 and/or cascaded AM2s.

HAL1
Meet HAL, an expert in room combining, paging and distributed
audio systems. is groundbreaking architecture is dimensions
beyond any other solution. HAL easily guides even novice us-
ers through what used to be complex tasks in just minutes. No
intricate matrix mixing or presets are required for room combin-
ing and paging. No virtual wiring required to distribute pages and
background music to multiple zones.
AM1 and AM2 as RADs with Mongoose or HAL
Seamlessly interface HAL to your facility with a broad variety
of peripheral devices including smart Digital Remotes, RADs,
portable and in-rack automixers, audio I/O and control logic ex-
pansion devices, wall sensors, ambient sensing mics, small remote
ampliers, and an advanced Paging Station.
e HAL and Halogen software check the status, location,
CAT 5 wiring integrity, and that audio is owing in all peripheral
devices, so you know your system is properly connected and ready
to go. HAL is more than just another DSP drag-and-drop system
— it has revolutionized system design and installation.
ree HAL Multiprocessors provide various audio I/O and
control options for both large and small installations, with
expandable systems capable of hundreds of mics (HAL1) or eco-
nomical and adaptable 4 in x 8 out (HAL3).
Find out more at rane.com/hal
AM Automixers with HAL
An AM1 is a RAD, and an AM2 is a RAD, and the nal output
of cascaded AM mixers is a RAD. Any of these allow the manu-
ally created mono mix to be sent digitally to a Rane HAL’s RAD
port via a shielded CAT 5e cable (or better). e Rane RADX
supports doing so portably – with the AM mixer(s) in a padded
rack or on a portable AV cart, for example. Once the AM mix is
in the HAL, additional signal processing such as EQ and com-
pression can be added. Control of the mix’s level using Rane’s
DR1 or DR3 Digital Remotes is a breeze.
AM1 use with HAL
e AM1 does not have a Cascade Out Port, therefore it is not
possible to cascade the AM1 mix into Halogen’s Gain-Sharing
Auto Mixer or Room Combine Processor. You must use the AM2
mixer for cascading with these DSP blocks.
AM2 use with HAL
e AM2 mixer digitally cascades into Halogen’s Gain-Sharing
Auto Mixer or Room Combine Processor. is means the gain-
sharing algorithm automatically treats AM2 microphones and any
other microphone wired into these DSP blocks as being part of
the same gain-share. is provides superior gain before feedback
since all mics in the room, regardless of where and how they are
plugged in to the audio system, all work as one. is maintains
your feedback stability margin.
To maintain PAG & NAG like you never have before, connect
the AM2’s Cascade Out jack with a shielded CAT 5e (or better)
cable into any HAL’s RAD port. In Halogen software, in the Pro-
cessing Workspace, drag the AM2 onto the Cascade In on either a
Gain-Sharing Auto Mixer or a Room Combine Processor.
You can cascade as many AM2 mixers into these two DSP
blocks as you have RAD Ports available. With a maximum of 36
total RAD ports in a HAL1 full with EXP1s, and a maximum of
8 AM2s cascaded externally, over two thousand possible channels
are possible!

Applications
Facilities and rental agencies are called upon to provide either
equipment, or equipment and operators, for meetings or con-
ferences needing A/V support. e equipment providers must
ensure audio quality throughout the event to get repeat business.
However, the provided equipment may be operated by present-
ers who have no audio experience. If an operator is sent with the
equipment to set up and manage the system during the presen-
tation, that operator may have little audio experience. Pitfalls
abound when interconnecting the system, and managing multi-
microphone gain before feedback, mixing and volume. Handling
iPod and laptop playback and/or recording adds even more
complexity. Enter the Rane AM Automixer.
e AM1 makes it easy for an inexperienced operator to
quickly set up and manage audio for a multimedia presentation
involving up to four participants with microphones (wired or
wireless) and several program audio sources (e.g., DVD, Laptop,
MP3 player).
e AM2 easily handles an eight-person discussion panel or
board meeting. Additional AM2 mixers easily handle more mics
when needed, all gain-sharing, making operation simple.
e AM1 provides line audio sources, manually mixed since
there is no acoustic feedback potential. e AM1’s exible line
input combination of RCA, 3.5 mm and separate USB Charge
and Audio I/O ports makes integration and cabling easy. And
since the USB Audio port can simultaneously playback audio and
record the AM1’s output, the same laptop can be a source and a
recording device to document AV meetings, presentations, train-
ings, and family karaoke nights for AV contractor employees.
e AM Automixer oers a professional integrated solution
that provides superior automatic gain before feedback while
eliminating operator error with simple controls. e microphone
gain-sharing algorithm automatically and appropriately attenuates
mics not in use while maintaining the 3 dB per doubling of mics
for dierent (noncoherent) talkers, and 6 dB per doubling for the
same (coherent) talker who is directly between two mics. ink of
the person wearing a live lavalier or headset, while approaching a
live podium mic...no problem!

Interconnection-1
Introduction
is note, originally written in 1985, continues to be
one of our most useful references. It’s popularity stems
from the continual and perpetual difficulty of hooking
up audio equipment without suffering through all sorts
of bizarre noises, hums, buzzes, whistles, etc.— not to
mention the extreme financial, physical and psycholog-
ical price. As technology progresses it is inevitable that
electronic equipment and its wiring should be subject
to constant improvement. Many things have improved
in the audio industry since 1985, but unfortunately
wiring isn’t one of them. However, finally the Audio
Engineering Society (AES) has issued a standards
document for interconnection of pro audio equip-
ment. It is AES48, titled “AES48-2005: AES standard
on interconnections —Grounding and EMC practices
— Shields of connectors in audio equipment containing
active circuitry.”
Rane’s policy is to accommodate rather than dic-
tate. However, this document contains suggestions for
external wiring changes that should ideally only be
implemented by trained technical personnel. Safety
regulations require that all original grounding means
provided from the factory be left intact for safe op-
eration. No guarantee of responsibility for incidental
or consequential damages can be provided. (In other
words, don’t modify cables, or try your own version of
grounding unless you really understand exactly what
type of output and input you have to connect.)
