DESCRIPTION
The Bogen Series 15-1 Centralized School Sound
System is designed to serve up to 50 rooms. It incorpo-
rates one Model MCT-1 Control Center and either one
or two Model SBS-25 Switchbanks, and is housed in a
desk-top consolette. The Series 15T- 1 accommodates up
to 25 rooms and includes one Control Center, one
Switchbank and one Model TP-160B AM/FM Tuner
housed in a desk-top consolette. The Series 15-2 consists
of one Control Center, one or two Switchbanks, one
AM/FM Tuner and one BSR 3-speed record changer. It
is housed in a desk-top, dual consolette and serves up to
50 rooms. The Series 15-3 consists of one Control
Center, one or two Switchbanks, one AM/FM Tuner
and one 3-speed record changer. It can accommodate up
to 50 rooms and is operated from a sturdy free-standing
console.
Each system has one 35-watt program channel and an
independent 4-watt intercom channel. The program
channel has two low-impedance microphone inputs
which can be used balanced or unbalanced. It also has
inputs for radio, phono and tape program sources and a
fader control to select either radio or phono-tape. The
selected program may be used alone or may be mixed
with the microphone program.
The MCT-1 control panel has a loudspeaker which
serves as both a program monitor speaker and an inter-
com transmitter/receiver. By means of the intercom
channel, the operator may hold a two-way conversation
with occupants of any room without disturbing the pro-
gram being transmitted to other rooms. If desired, the
intercom channel also may be used to permit the op-
erator to monitor any selected room through its room
speaker.
Model 15-2
In addition to the control panel, each Series 15 con-
solette or console has one or two switchbanks contain-
ing the individual room selector switches. In the stan-
dard system, these are 3-position lever switches used to
connect each room speaker to either the program (A)
channel or the intercom (C) channel, or to disconnect
the speaker from the system (Systems with optional
light-annunciator call circuit have four-position lever
switches). The units have an Emergency mode of opera-
tion which overrides these selector switches. When
operating in Emergency, the operator can transmit from
the control panel speaker to all room speakers, regard-
less of the settings of the room selector switches or of
other program inputs to the speakers. The Emergency
function operates whether the power switch is on or off.
