INTRODUCTION

The model CHBIOO is a general purpose
loo-watt public address amplifier. It features
five separate inputs with facilities br- selection
and mixing of up to three inputs. A master vol-
ume control provides control of overall gain.
Separate Bass and Treble controls are incorpor-

ated for adjusting tonal balance.

Outputs are provided for all standard speaker
impedances and for operation with 25-volt and
70-volt long line speaker systems. Two quick
disconnect type plugs permit quick connection
of speaker system.

ACCESSORIES

MODEL SR2 REMOTE CONTmLLER

Permits the user to control the gain of the
Mic l and Mic Z/Mag Phono inputs from dis-
tances up to 2,000 feet from amplifier without
sacrificing power or signal quality. Allows you
to mix and fade the two signal inputs.

MODEL LK-5 LOCKING PLATE

Model LK-5 Locking Plate is designed to pre-
vent unauthorized tamperingwith controls ofamo
lifier. Comes complete with instructions and a
set of two keys. As a safety factor. key cannot
be removed when lock is in open position.

MODEL LPG-4 PHONO PLAYER TOP

Model LPG-4 is a complete 4-speed phono-
player designed to be mounted directly on top of
of the amplifier. The unit comes complete with

allnecessary hardware. It can be easily install-
ed and connected to amplifier with only a screw-
driver. It includes a 4~speed vibration-isolated
turntable and tone arm housing a dual-Styli
turnover cartridge.

MODEL WMT-l LINE MATCHING TRANSFORMER

Used with this amplifier for distribution of
background music directly from a leased tele-
phone line, wired music systems or any 0 level
500/600 ohm line. Provides an impedance match
between 500/600 ohm balanced line and high
impedance input of amplifier. The WMT-l has a.
3-screw terminal strip for input connections and
output. No wiring or soldering required for making
normal connections between amplifier and input
or output lines. Slight modification permits
WMT-l connection to MIC input of amplifier.
