CIS120 –

ELECTRICAL INSTALLATION
Note:
Observe all local and national codes when
installing the CIS120.
The CIS120 is supplied with a strain-relief sliding clamp for
securing jacketed cable or flexible conduit.
If you are using 1/2 inch solid conduit or flexible armored
conduit, then the strain-relief can be removed and fittings
for securing solid conduit used instead (see page 9).
All connections to the loudspeaker must be made with
the power amplifier turned off.
Amplifier connections
The following examples of 70 V and 100 V connections
show an EAW Commercial CAM160, a typical mixer/amplifier.
Its speaker-level output is a screw terminal strip, with outputs
for 25 V, 70 V, 100 V, Ground, and 4 ohm.
70 V connection example
1. Connect the 70 V terminal on the amplifier to the
IN + input connection on the CIS120.
2. Connect the GND terminal on the amplifier to the
IN – connection on the CIS120.
3. Select the appropriate power tap on the CIS120
from the inner ring marked 70 V, and make sure the
other switch is set to "transformer."
100 V connection example
1. Connect the 100 V terminal on the amplifier to the
IN + input connection on the CIS120.
2. Connect the GND terminal on the amplifier to the
IN – input connection on the CIS120.
3. Select the appropriate power tap on the CIS120,
from the outer ring marked 100V, and make sure
the other switch is set to "transformer."
Low impedance connections
The following example of a low-impedance connection
uses a EAW Commercial CAZ2500 amplifier to power
the CIS120. This amplifier also uses a screw-terminal
output.
1. Connect the A + terminal on the amplifier to the
IN + input connection on the CIS120.
2. Connect the A – terminal on the amplifier to the
IN – connection on the CIS120.
3. Select the "direct" position on the CIS120 to bypass
the power-tap transformer and run the CIS120 as a
constant impedance loudspeaker (8 ohm nominal).
