clamp assembly. The cover of the Model
56 will have to be removed to gain access
to mounting holes. Be careful when select-
ing the mounting screws—exceeding the
recommended
5 /

-inch length will cause
the mounting screws to damage the Model
56’s internal components.
Model 70 Interface
In most cases Model 35 and/or Model 38
Talents Amplifiers will be used to drive
headphones associated with a Studio-
Comm installation. In special cases a line
level signal may be required to interface
the Model 55 Central Controller’s talent
amplifier output with other audio equip-
ment. An example would be to use the
Model 55 with an existing headphone
system. The Model 70 Interface is used
to convert the talent amplifier signal to a
stereo, balanced line level signal.
Installation is very simple. Connect the
Model 70 to the Model 55 Central
Controller’s talent amplifier output using
a standard 3-conductor microphone-type
cable. For best performance, use low-
capacitance shielded cable.
The Model 70 provides independent left
and right balanced outputs. Pin 1 is shield,
pin 2 is signal positive (+ or hot), and pin 3
is signal negative (– or cold). The elec-
tronically balanced outputs have a nominal
signal level of +4dBu and are capable of
driving loads of 600 ohms or greater.
The Model 70 can be used by itself, or in
conjunction with up to four Model 35 or
Model 38 Talent Amplifiers. The loop
through connector on the Model 70 can
be used to connect to a Model 35 or 38
Talent Amplifier.
Configuration
Many StudioComm functions can be
configured to meet the exact needs of your
installation. Here’s an overview of what
you can configure:
• –10dBV or +4dBu sensitivity for each
input
• Stereo or mono for each input
• –10dBV or +4dBu level for the dub
output
• Dim level
• Momentary or latching operation for
mono, talk to phones, and slate buttons
• Auto dim off function
• Slate feed to phones
