DESCRIPTION
The BC-3C Standard Consolette is designed to
handle the programming schedules of a station
equipped with one or two studios, an announce booth,
a control room, two turntables, one tape recorder and
one auxiliary such as a film projector. The thirteen
inputs include six microphones, two turntables, one
tape, one network, two remote and one auxiliary.
The network and remote lines may be monitored
by using the phone jack. Eight inputs may be simul-
taneously mixed. Separate audition and program
channels are provided and the monitoring amplifier
may be switched to the turntable cue position, pro-
gram line, audition line or external input.
The BC-3C is completely self-contained, including
the amplifiers and power supply. The unit is styled
for convenience in operation, with the logical ar-
rangement of controls using col6red knobs and for
convenience in servicing, with the hinged front panel
and removable louvred top cover.
The console housing
is
compact and designed to
match the styling of other RCA ,Audio consolettes
such as the BC-5B or the BC-6B. All these units are
designed to be mounted on a Bat desk or surface.
Another convenient feature is the script holder which
keeps the program where the operator may check it.
Associated Equipment
The necessary auxiliary units such as microphones,
loudspeakers, turntables, tape recorders and warning
lights, may be selected from the RCA catalogs. A
separate sheet of instructions is packed with each unit.
