AM1
AUTOMIXER
Data Sheet - 1
General Description
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, or add
more gain-shared mics using up to seven Rane AM2 Automixers
(sold separately). Use the RAD Port to transport the main mix
digitally via CAT 5 to either a Rane HAL’s RAD Port, or to 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 out-
puts (+12 dBV max). A front panel Mic Mix Level control adjusts
the volume of all automixed mics.
e AM1 is optimized for automixing speech. e mic inputs
have a xed 80 Hz to 7 kHz bandpass lter 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-pow-
ered 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 cor-
responding 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 either a Rane
HAL’s RAD Port for further signal processing and control, or to
a Mongoose for routing to 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 cas-
caded 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 head-
phone 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.
