room source or the headphone source.
A push button, along with an associated
LED, provides the studio on/off function.
A rotary potentiometer is used to set
the level.
Dub Output
A stereo line-level output is provided as
a dub (copy) output. Any of the seven
inputs can be assigned to the dub output.
The dub output can also be configured to
follow the source selected for the control
room output. The slate function allows
communications (voice) audio to be sent
out the dub output. For convenience, the
dub output is available from both the front
and back panels of the Model 50.
Communications Functions
The Model 51 Control Console contains
an internal microphone that is used in
conjunction with the three communica-
tions functions. The talk to studio function
interrupts the studio source and sends
communications audio. The talk to phones
function either interrupts the phones
source or adds (sums or mixes) communi-
cations audio with the phones source. The
slate function interrupts the dub source
and connects communications audio. The
slate function can be configured to send
a 50 Hz sine wave along with commu-
nications audio. The audio level of each
communications function is individually
adjustable.
MIDI Control
All Model 50 Central Controller functions
are controlled using system-exclusive
MIDI messages. The Model 51 Control
Console “speaks” this language, and
in most applications a Model 51 will be
utilized. In special applications the Model
50 Central Controller can be connected di-
rectly to a MIDI bus, allowing the creation
of a fully automated recording or audio
routing system. (For more information
on MIDI support, refer to Appendix A.)
Configuration
The Model 51 Control Console can be
configured to make the system meet a
user’s exact operating environment. As
previously discussed, each of the seven
stereo line inputs can be independently
set for –10 dBV or +4 dBu operating lev-
els. They also can be set for either mono
or stereo operation. In the mono mode a
signal connected to the left input is sent to
the left and right outputs. The dub output
level can be set for a nominal –10 dBV or
+4 dBu output level.
Unique to the system is the ability to con-
figure the dim level to one of six values,
ranging from full attenuation to a modest
10 dB reduction. The auto dim off function,
when configured, allows any change in
the control room level potentiometer to
automatically turn off an active dim state.
The talk to phones function can be
configured to either interrupt the source
selected for headphone audio and con-
nect communications audio, or to have the
communications audio added (summed
or mixed) with the headphone audio.
The slate function can be configured to
generate a 50 Hz sine wave when activat-
ed. This provides an audible “marker” for
analog tapes, and a visual indication on
a wave form display screen.
Four functions can be set for push-to-latch
operation if desired: talk to studio, talk to
phones, slate, and control room mono.
