unique stereo preamplifier section. This
allows each Model 38 user to create an
individual headphone mix, solving the
classic problem of wanting “more me”
in the phones! Like the Model 35, the
Model 38 is linked to the Model 50 Central
Controller by a single microphone-type
cable.
System Features
Stereo Line Inputs
The Model 50 contains seven stereo line-
level inputs which are compatible with
both balanced and unbalanced signals.
Each input is independently software
configurable for a nominal input level of
–10dBV or +4dBu. This allows direct
connection with virtually any audio source.
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 se-
lected source to be sent as the control
room output.
Studio Monitoring
The studio monitoring source is config-
ured to follow the selected control room
source or 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)
communications audio with the phones
source. The slate function interrupts the
dub source and, if configured, the head-
phone source and connects communica-
tions audio. The slate function can be
configured to send a 50Hz sine wave
along with communications audio. The
audio level of each communications func-
tion is individually adjustable.
MIDI Control
All Model 50 Central Controller functions
are controlled using system-exclusive MIDI
