Each input can also be configured to
operate as a mono input. In this manner,
a signal connected to the left input is
routed to both the left and right outputs.
For convenience, input 7 is located on
the front panel of the Model 50; inputs 1
through 6 are located on the back panel.
Control Room Monitoring
The control room section provides two
stereo line-level outputs for driving two
power amplifiers associated with monitor
loudspeakers. Seven buttons are used to
select the input source to be monitored.
The control room level is adjusted using
a smooth-feeling rotary potentiometer. The
Dim button allows the control room level
to be temporarily reduced. The Control
Room A/B button allows the control room
A or B outputs to be activated. The Mono
button allows the sum (L+R) of the select-
ed source to be sent as the control room
output.
Meter Output
The meter output provides a stereo output
that “follows” the source selected for the
control room. The signal is not affected
by the control room level circuitry, but is
“post-mono.” The meter output is intend-
ed to be connected to VU- or PPM-type
meters or meter panels that contain series
current-limiting resistors or input buffer
amplifiers. In addition, they must support
meter calibration to ensure precision level
reading.
