New Top-of-Line Bogen Amplifiers
Bogen Division of Lear Siegler. Inc. announces Its new top-of-the-line packaged amplifiers. the CT-B Series. designed especially
or locations such as churches. auditoriums
and arenas.
The CT1 OOB. wi h 1OO-watt ou put. and the
CT60B. wi h 60-watt output. are built exclusively with integra ed circui s and silicon ransistors and diodes. Built-in fea ures begin with
our balanced. low-Impedance. transformerIsolated microphone inputs. Adding Bogen's
optional PMM-2B preamplifier. which mounts
to the front panel, expands the number of similar microphone inputs to six. The CT-Bs also
will accommodate high-impedance microphones through a rearrangement of jumpers on
their P.C. boards. A phantom supply is included
for the use of condenser microphones. A
unique, built-in acoustic equalizer has ten slide
controls with filters set at preferred ISO center
frequencies for ± 12 dB boosts and/or cut.
Rubber locking grommets prevent accidental
movement of the slides once they are set to a
room's requirements. An electronic compressor maintains constant output levels, regardless of input variations. This eliminates sudden
surges in background music and compensates
for poor microphone technique. The compressor is screwdriver-adjustable, through the front
panel. for wide differences in input level.
These amplifiers simultaneously mix inputs
of four microphones (six if PMM-2B is used)
and an auxiliary program source. Two highimpedance auxiliary inputs accept a tuner,
tape/cassette player, turntable with a ceramic
cartridge or Bogen's TG-4B Mul iple Tone Generator. A 500/600-ohm line can be fed to an inpu or from an output when Bogen's WMT-1
Transformer is installed on the back of a CT- B.

when connected to a customer-supplied SPST
switch, lets special announcements override
other channels. Remote volume control also is
available for each channel with the optional
RVC-2B Controller from Bogen. Input connectors Include professional 3-pin female microphone receptacles and phono jacks for high·
impedance auxiliary sources A screw·terminal

control. compressor control and the ten equalIzer filter controls. Two Similar amplifiers can
be bridged to double the number of Inputs or
the outpu s can be connected in series to
double the power Input. Other can eniences
include thermal breakers and circuit breakers
that protect against overloads. power surges
and accidental shorting. A lighted power swi ch
and an AC outlet also are built into the CT-B
amplifiers.
