QUICK START
If you’re setting up the AM2 automixer, then this Quick Start is
for you. It’s intended to get your audio working quickly in just
422 words.
Plug microphones into the Mic Inputs using standard XLR
mic cables. Condenser mics need the MIC +48V switch position.
Use the MIC +0V middle position for dynamic mics. The LINE
position is used when a wireless microphone’s receiver output is
connected.
Connect the Main Output XLR to your amplifier or powered
loudspeaker and select the LINE switch position. If the Main
Output feeds a microphone input, select the MIC position.
Start with the gray OUTPUT LEVEL knob turned all the
way down – fully counterclockwise. One at a time for each mic,
talk very loudly and very closely to the mic and adjust the cor-
responding black LEVEL control so only the loudest speech just
barely flickers the red overload (OL) indicators. Once the input
gains are set, the AM2 automatically controls the mic mix to
avoid feedback. (You won’t need to ride these controls.)
Turn on the amplifier/loudspeaker and turn it up about half
way. Also turn the OUTPUT LEVEL knob up until the volume
is appropriate for your application.

If the system feeds back (that horrible squeal), your mics
are hearing too much from your loudspeakers. First try moving
the mics farther from the loudspeaker and/or pointing the mics
and loudspeakers away from each other. Next, try turning down
the gain on the amplifier or loudspeaker. If this does not reduce
feedback, don’t reach for the black Mic Input knobs, instead turn
down the OUTPUT LEVEL.
Daisy-chain up to eight AM2s together by connecting
CASCADE IN to CASCADE OUT. The Main Output on each
AM2 delivers a gain-sharing automix of it’s Mic Inputs and all
upstream Inputs. This means the mix of all Mic Inputs is on the
Main Output of the last AM2 in the daisy-chain. Though each
AM2’s OUTPUT LEVEL control always adjusts the volume of
it’s respective XLR OUTPUT, the last OUTPUT LEVEL affects
all
Mic Inputs to it’s Main Output including the RAD PORT.
If your AM2(s) connect to a Rane Mongoose, the last AM2
in the cascade needs its RAD PORT connected with a shielded
CAT 5 cable to one of the Rane Mongoose’s rear panel Remote
Audio Device ports. Some systems may provide a wall plate loca-
tion to connect the RAD Port cable.
If you have line sources such as iPods® or CD/DVD players
you would like to mix with these mics, or would like USB audio
playback or recording, look at the Rane AM1.
