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 (62.5 ohms) or 70-volt (500 ohms)
constant-voltage systems. A terminal strip with screw terminals
allows convenient connection of speakers, except TO-volt. For
70-volt operation, a quick-disconnect speaker socket is pr6-
vided.
The CIO operates from a 120-volt. 60 Hz source and has a
maximum power consumption of 46 watts. A thermostat
enclosed in the power transformer protects the amplifier against
overloads.
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 Leviton 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 amplifier to a water or
steam pipe.
INSTALLATION
UNPACKING
The amplifier was carefully checked before leaving the
factory. Inspect the shipping container and unit carefully for
indications of improper handling; if the unit has been damaged,
make an immediate claim to the distributor from whom it was
purchased, or if the amplifier was shipped directly to you, notify
the transportation company without delay and place your
claim.
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 a suitable in-line type microphone
transformer.
