may consist of a “true” stereo signal, a
dual-channel monaural signal, or one or
two independent monaural signals.
Associated with the left channel input are
two buttons, labeled OUT L and OUT R.
When both buttons are in the off (out)
position, the left input signal can’t be
connected to the left or right output bus.
(The final connection to the buses actually
occurs by means of the bus assignment
buttons.) Placing the OUT L button in the
on (in) position allows the left input signal
to be connected to the left output buses;
OUT R allows the left input to be con-
nected to the right output buses. Placing
both buttons to the on (in) position allows
the left input signal to be connected to
both the left and right output buses. Two
buttons are associated with the right
channel input and function in the same
manner.
The number of routing possibilities may
seem almost endless but you math
experts know there are actually only 16!
If you spend a bit of time thinking about
the routing you’ll see how a variety of
stereo and monaural inputs can be routed
and combined to create virtually any
desired stereo or monaural output.
Bus Assignment
Signals from the left/right assignment
buttons are sent to the main and AUX bus
assignment buttons. These two buttons
operate in the same fashion as described
for the mic/line input channels. The main
button assigns the line input signals to the
main bus. The AUX button assigns the line
input signals to the AUX mix bus and
enables the AUX interrupt control bus.
Setup Functions
The Model 750’s setup section will be a
“new animal” to most operators, but is
really quite simple and intuitive to under-
stand and use. (The simple and intuitive
part will become more obviously after you
read the following section!)
The setup section allows the recording
and playback of voice identification sig-
nals, along with the generation of sine-
wave audio tones.
Setup Direct Output and Bus
Assignment
A separate stereo output is provided on
the back panel, giving direct access to
the voice and tone signals generated by
the setup section. Whenever one of the
setup section’s voice identification or tone
functions is active, the signal generated
will always appear on the setup direct
output. Only if the bus assignment buttons
are activated will the setup signals be
connected to the main and AUX audio
buses. This allows the buses to continue
to be used for normal audio signals, even
while voice identification or sine-wave
tones are being generated. What a con-
cept—your entire audio mixer doesn’t
have to be “tied-up” so you can generate
a 1kHz tone for some geek at a TV station
in North Dakota. (The author is living
dangerously—he has family in Minot!)
Voice Recording
Three push-button switches allow you to
record custom voice identification mes-
sages; 12 seconds maximum for the L+R
segment, 4 seconds maximum each for
the L Only and R Only segments. One
status LED, red in color, is associated with
the three record buttons. The LED will light
