e Rane AM1 is part gain-sharing automatic mic mixer, part
manual line mixer, part USB audio I/O device, and simultaneously a Rane RAD. Use it as a standalone mic/line mixer, add
more gain-shared mics using up to seven Rane AM2 Automixers
(sold separately), and/or use the RAD Port to transport the main
mix via a Rane Mongoose to a CobraNet network.
Each of the four XLR Mic Inputs oers front panel input
Level controls feeding a gain-sharing automatic mixer. Rear panel,
3-position switches for each Mic Input support dynamic mics (no
phantom power), condenser mics (48 V), or wireless receiver outputs (+10 dBu max). A front panel Mic Mix Level control adjusts
the volume of all automixed mics.
e AM1’s mic inputs are optimized for automixing speech.
e mic inputs have a xed 100 Hz to 7 kHz bandpass lter
(2nd-order Butterworth) to provide the best voice-only automatic
mixing using a gain-sharing algorithm.
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 monoed, 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-powered devices. e separate orange USB Audio Input also oers a
front panel Level control for the 16-bit, 48 kHz digital audio that
is monoed immediately upon entry.
Signal and Overload indicators monitor the Mic and Aux
Inputs, the Mic Mix and the Main Mix. Indicators ank the corresponding Level controls.
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 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 aects 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.
e RAD Port sends the AM1 output mix to a Rane Mongoose for routing to output RADs and/or a CobraNet network.
e Cascade IN accepts audio and data from a Rane AM2’s Cascade OUT. is adds the AM2’s eight mic channels to the AM1,
creating a 12 channel gain-sharing automix. Up to seven AM2s
can be cascaded to a single AM1, oering up to 60 gain-shared
mics. 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 AM1’s physical location,
positive USB audio device OS registration and AC power status.
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 headphone jacks with a Level control are provided. 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.

Facilities and rental agencies are called upon to provide either
equipment, or equipment and operators, for meetings or conferences 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 presenters who have no audio experience. If an operator is sent with the
equipment to set up and manage the system during the presentation, that operator may have little audio experience. Pitfalls
abound when interconnecting the system, and managing multimicrophone gain before feedback, mixing and volume. Handling
iPod and laptop playback and/or recording adds even more
complexity. Enter the Rane AM1.
Example AM1 System
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 AM1 oers 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 dierent (noncoherent) talkers, and 6 dB per doubling for the same
(coherent) talker who is directly between two mics. Appropriately,
line audio sources are 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, trainings, and family
karaoke nights for AV contractor employees.

General Description
e Mongoose and its Tracker software work with Rane’s Remote
Audio Devices (RADs) and your CobraNet network to deliver
digital audio to the “last mile” of installations – between the
equipment room/rack and remote spaces. OK, it’s not a mile, we
lied: it’s actually 150 meters (492 feet to those in Liberia, Myanmar and the USA).
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 Secondary/backup ports. e 32 matrix router outputs transmit 16
channels to eight RADs and 16 more channels to two CobraNet
transmit (Tx) Bundles.
A family of RAD models is shown to the right. Each converts
analog audio to or from 24-bit, 48 kHz digital audio. Many
RADs mount in a standard US electrical gang box, typically scattered throughout a facility. Shielded CAT 5 cable and termination
transport four digital audio channels – two channels in each direction – as well as power, ground and a communications channel
via Rane’s proprietary RAD Network.
