5S14) to
CUE position. The operator in the control room can
now talk to the "remote" operator.
5. Plug headphones into the PHONE jack 5 Jl, set
the PHONE switch to REM and turn REM 1 (or
REM 2) to PH position. The control room operator
can now listen to the "remote" operator. By switch-
ing the remote line switch (REM 1, 5S13 or REM 2,
5S14) between the CUE and PH positions, the con-
sole operator has a two way communication system
with the remote operator. This remote talkback may
be operated while a program from another source is
on the air.

To Feed Cue to Remote Line (REM 1, REM
2)
Turn switch REM 1 (5S13) or REM 2 (5S14) to
the CUE position. Cue will be automatically fed over
the remote line from the monitor output.
To Cue Mixer SAT4 to SAT8 Inputs
The turntable, network-remote, tape and auxiliary
mixer attenuators, 5AT4 to 5AT8, are equipped with
"cue" switches which in the maximum counterclock-
wise position connect the output of the turntables to
the CUE position on the monitor input selector
switch 5S15. It is also possible to connect to an ex-
ternal cue amplifier (see Installation).
Remote Line Selector Switches 5513 and 5514
Switch 5S13 controls remote line 1; switch 5S14
controls remote line
2.
The function of these four-position switches is to-
1.
Disconnect the remote line (OFF).
2.
Connect the remote line to the PHONE jack
5Jl (PH).
3. Connect the remote line to the output of the
monitor amplifier (through a pad for sending cue
(CUE).
4. Connect the remote line to the network-remote
line input channel (through 554, 5AT4 and 558)
(PGM).
PHONE Monitoring
Plug the headphones into the PHONE jack on the
front panel. Select the desired output by the PHONE
selector switch which has four positions, OFF-REM-
NET-PGM. The outgoing program may be moni-
tored by setting the control the PGM position; the
remote or network inputs may be monitored by set-
ting the control to the REM or NET positions, re-
spectively. This permits convenient cuing when shift-
ing from a live show to a remote or network or vice
versa.
MAINTENANCE
The BC-3C Standard Consolette may be easily
serviced without disturbing the installation. The top
cover which can be easily removed is fastened to the
consolette by four Camloc fasteners. The front panel
is hinged at the bottom and secured at the top by
two Camloc fasteners. The front panel is held in the
open position by two fall supports.
Tubes
The tubes of the amplifiers and power supply
should be checked periodically either in a tube tester
\
or by measuring the socket voltages. Refer to the
Tube Socket Voltage chart. The values shown are
measured with a voltmeter having a resistance of
20,000 ohms-per-volt. Slight variations may be due
to component tolerances.
Fuse
A power fuse is located at the right front of the
preamplifier mounting shelf. This fuse should be
replaced only with a type 3AG, 3 amp time lag fuse.
