Challenger Solid Siate Series
MODEL CIO
10-WATT TRANSISTOR
PUBLIC ADDRESS AMPLIFIER
OPERATING AND INSTALLATION MANUAL
DESCRIPTION
Bogen Model CIO is a fully transistorized public address
amplifier rated at 10 watts. The unit will accommodate one
high impedance microphone and one auxiliary program
source such as a tuner, tape recorder, or phonograph with
ceramic cartridge. Individual controls are provided for the
microphone and auxiliary inputs along with a treble control
for adjustment of tonal balance.
Balanced or unbalanced outputs are provided for 4, 8, and
16-ohm speakers, and 25-Volt (62.1 ohms) or 70-volt (490
ohms) constant-voltage systems. A terminal strip with screw
terminals allows convenient connection of speakers, except
70-volt. For 70-volt operation, a quick-disconnect speaker
socket is provided.
The CIO operates from a 120-volt, 60Hz source and has
a maximum power consumption of 46 watts. A thermostat
enclosed in the power transformer protects the amplifier
against overloads.
INSTALLATION
UNPACKING
The amphfier was carefully checked before leaving the
factory. Inspect shipping container and unit carefully for
indication of improper handling; if the unit has been
damaged, make an immediate claim to distributor from
whom it was purchased, or if the amplifier was shipped
directly to you, notify transportation company without
delay and place your claim.
POWER AND GROUNDING
The amplifier is furnished with an ac line cord
terminated in a three-prong plug. The line cord should be
plugged into a three wire grounded outlet providing a
nominal 120-volt,.60 Hz power source. This will ground the
amplifier as well as supply power to it.
It is important to ground the amplifier. Therefore, if a
three-wire outlet is not available, an adapter such as Levitón
No. 5017 should be used to convert a standard two-wire
outlet for use with three-wire plugs. The adapter is provided
with a grounding pigtail which should be connected to the
screw holding the wall plate to the receptacle.
In some areas, the wall plate screw is not grounded. In
this case it will be necessary to connect a grounding wire
from
the GND terminal on the rear chassis of the amphfier
to a water or steam pipe.

INPUT CONNECTIONS
MICROPHONE: Connect the microphone to the MIC
receptacle on the rear panel.
The microphone should be of the high-impedance
ceramic, or dynamic type. Connect the microphone as
shown in figure 1. The length of the interconnecting cable
should be under 35 feet. Where longer lines are necessary, a
low impedance microphone should be used along with
Model IT-1, in-line type microphone transformer.
MICROPHONE PRECEDENCE: Microphone precedence
may be accomplished by connecting the circuit shown in
PRINTED IN U5.A.
