Bat" indicator comes on, you have approximately 15 to 30 minutes of battery life
remaining.
The AlphaMix is equipped with meter lamps used for night viewing of the meters.
The light source for this meter back lighting is provided by a 18,000mc (18
candela) high performance "green" LED in conjunction with a specially made
woven fiber optic light transmission panel. These two new technologies were
chosen as they provide good quality back lighting without adding noise to the
mixer as some electro-luminescent systems do. The use of the meter back
lighting adds approximately 40mA of power consumption to the mixer.
ADDITIONAL FEATURES:
A.
SLATE MICROPHONE
The AlphaMix 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 AlphaMix.
microphone is activated, the input channels are automatically muted.
B.
REFERENCE OSCILLATOR
The AlphaMix 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 AlphaMix'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 can monitor levels from the mixer only. We have chosen 440Hz simply
because it is much more pleasant in your headphones than the typical 1Khz used
by other manufacturers. We have used 440 Hz on our mixers for many years.
The reference oscillator is equipped with a level adjustment trim pot located on
the bottom panel of the AlphaMix. This adjustment is factory calibrated and
should not be adjusted without proper measurement equipment.
C.
BATTERY TEST
In addition to the low battery indicator on the LCD meter, the AlphaMix is
equipped with a push button activated battery test function: When this "Batt Test"
button is pressed the remaining battery life is displayed on the top (left meter). A
full battery will indicate approximately "0" on the meter. A dead battery will not
indicate on the meter. You can read the meter as a "fuel gauge". Full bar = full
battery, half bar = half battery, etc. This battery level meter can be adjusted for
the differences in NP-1 battery voltages.
adjusted to specific NP-1 type batteries via a bottom panel mounted rotary
switch.
