D E S C R I P T I O N
The Bogen Model CHSlOO is a fully transistorized
public address amplifier rated at 100 watts. The unit
will accommodate two microphone inputs and two
auxiliary inputs for a tuner, tape recorder, or phono-
graph with a ceramic cartridge. The amplifier will
accommodate either high or low impedance micro-
phones, and no transformer is required to change from
one microphone impedance to the other.
Individual volume controls are provided for each
microphone input. A fader volume controls selects and
adjusts the level of the desired auxiliary input and
permits fading between the two inputs. A master vol-
ume control regulates the mixed output level. Sep-
arate bass and treble controls permit adjustments for
tonal balance.
Outputs are provided for 2, 8 and 16-ohm speakers
and for 25-volt and 70-volt b a l a n c e d s p e a k e r l i n e

PMA-2 ADD-ON PREAMPLIFIER
The Bogen Model PMA-2 Preamplifier is designed
to provide two additional microphone channels for the
CHSlOO amplifier. Each preamp channel has its own
volume control and will accommodate either high-im-
pedance or low impedance microphones. The unit is
connected to the Preamp Accessory socket on the top
chassis of the CHSlOO amplifier. When installed, the
PMA-2 control knobs protrude through the front panel
of the CHSlOO amplifier.
especially for matching either inputs from or outputs
to a 500/600 ohm line. As an input matching trans-
former it may be used with the Bogen amplifier for
distributing background music which has been trans-
mitted over leased telephone lines. The, accessory
also functions as an output matching transformer in
feeding special program material over a 500/600 ohm
telephone line for transmission to a local broadcast
studio.
