METERS:
A.
PEAK READING METERS
The M3 Mixer is equipped with a custom made LCD meter. We designed this
meter to be easy to read and camera emulating. Because the most common use
of this type of mixer is with Betacams, we designed the M3's meters to emulate
the peak reading attributes found on many Betacams. In this manor, you can be
confident of your recording levels even when the Betacam is being fed via
Betasnake cable or wireless transmission. The LCD meter also displays Left and
Right Limiter functions as well as Low Battery Warning. When the "Lo Bat"
indicator comes on, you have approximately 30 minutes of battery life remaining.
You should replace the batteries at your earliest convenience. This low battery
indicator can be set to sense the use of various battery types including AA
alkaline, and various voltage NP-1 rechargeable batteries.
The M3 Mixer is equipped with meter lamps used for night viewing of the meters.
The use of the meter back lighting adds approximately 80mA of power
consumption to the mixer. The continuos use of the meter lamps will shorten
your battery life by as much as 35%.
ADDITIONAL FEATURES:
A.
SLATE MICROPHONE
The M3 Mixer is equipped with a slate microphone. This microphone is activated
when the front panel "slate" momentary push button switch is pressed. The slate
microphone allows the operator to put voice slates (notes) on tape for later
reference. These are normally notes for editing tape. A level adjustment trim pot
is located on the bottom panel of the M3 Mixer.
clockwise will increase the slate microphone level.
counter-clockwise will lower the level. Audio from the three input channels is
automatically muted whenever the Slate microphone button is pressed. This
assures that the slates are clean and easily understood.
B.
REFERENCE OSCILLATOR
The M3 Mixer is equipped with a reference oscillator used for setting of levels
between the mixer and recorder. This known reference level is also used when
transferring tape during editing. The M3's oscillator operates at 440Hz at "0" on
the meters. When setting up typical Betacams with LCD bar graph meters you
simply adjust the Betacams inputs until "0" is reached. From that point on, you
