The M3 contains two separate limiters that are controlled by one front panel
mounted switch. This switch has three settings: Off, Separate (S), and Ganged
(G). In the off position, no limiting occurs.
In the separate position, the limiters act independently of each other. This is
especially useful when recording split tracks. I.E. interviewer and interviewee on
separate channels. Thus, if one person un-expectantly raises their voice, that
limiter will activate, but the other will not. In the ganged mode, both limiters are
tied together and can be triggered by either input. This is useful in recording
stereo as independent limiting would alter the stereo image.
PRACTICAL USE NOTE: IT IS HIGHLY RECOMMENDED THAT THE
LIMITERS BE USED AT ALL TIMES WHEN RECORDING TO BETACAM
TYPE CAMERAS.
Most video cameras have limited audio track headroom and can easily be
overloaded resulting in distortion of the recorded audio. Play it safe, use the
limiters!

TRANSCRIPTION OUTPUTS
The M3 Mixer also contains two dedicated outputs used to feed transcription
recorders. These connectors are located directly below the main XLR outputs.
They are 3.5mm Stereo connectors wired as follows: Tip = Left, Ring is Right,
Sleeve = Ground. These connectors provide switch-able line level (-10dBv) or
microphone level (–50dBv) signal. This is compatible with most transcription
cassette recorders. The level setting switches are located on the bottom panel of
the M3 mixer.

HEADPHONE OUTPUT
The Headphone output is located on the left side panel of the mixer. The M3
Mixer's headphone amplifier circuitry is designed to drive virtually any headphone
with an impedance rating of 32 to 600 Ohms.
controlled by the use of two switches and a volume control that are conviently
located on the front panel. The two switches are used to control what the
operator listens to. The most commonly used switch is located on the front panel
and is used to allow the operator to chose between monitoring right channel to
both ears "R", normal stereo "S", left channel to both ears "S"' Mono sum of left
and right signals "M" and well as pre-fader monitoring of channels 1,2 and 3 and
M-S decoding of MS stereo signals. The second switch is located on the upper
right corner of the front panel.
