supply utilizes a toroidal mains transformer
for quiet audio operation.
Model 69 Control Console
The Model 69 Control Console is a com-
pact, self-contained unit designed to be
located at the operator’s position. It allows
fingertip control of all monitoring para-
meters. Numerous LEDs provide complete
status information. The Model 69 supports
two 6-channel (surround) and two
2-channel (stereo) input sources, along
with one 6-channel monitor output.
The Model 69 provides four buttons and
associated LEDs for selection of the input
source to be monitored. While in most
cases only one input source will be moni-
tored at a time, multiple inputs can be
selected for simultaneous monitoring.
This allows two, three, or all four of the
inputs to be combined (“summed”). While
there is no independent control of the
input levels, this feature can be useful
for creating rough mixes from the source
signals. It is also a fast, effective means
of making a “seat-of-the-pants” check
on the phase relationship between syn-
chronized signals.
The monitor output level is controlled
either through the use of a large, easy-
to-use rotary control, or by enabling the
preset reference level. For operator con-
venience, the dim function allows the
monitor output level to be reduced by a
fixed dB amount. The mute all function
disables all monitor outputs by activating
the mute relays on the Model 68 Central
Controller.
