– CIS120
3. FRONT PANEL FEATURES
1. MAIN ASSEMBLY
The CIS120 is supplied with the driver, crossover,
transformer, front baffle, and rear metal can, all assembled
in one unit. Do not disassemble this unit.
2. SELECTOR SWITCHES
Two rotary switches allow you to select the different
transformer power taps, or to bypass the transformer. Use
a flat-ended screwdriver to make adjustments.
Turn off power to your amplifier before making any
adjustments.
Power Tap Selector
The CIS120 can be used in 70 V or 100 V constant-voltage
distributed systems.
For 70 V systems, select power
taps from 16 W, 32 W, 64 W, and
128 W.
For 100 V systems, select power
taps from 32 W, 64 W and 128 W.
Transformer/Direct Selector
In the transformer position, the
CIS120 uses an internal transformer
with a choice of power taps. Set
this if you are using a constant
voltage amplifier of 70 V or 100 V.
In the direct position, the
transformer is bypassed, the
power tap selector has no effect,
and the CIS120 presents an
overall impedance of 8 ohm to a
conventional power amplifier.
3. FRONT GRILL
The CIS120 is supplied with the front grill not attached to
the front baffle. It comes with an insulating backing sheet
already attached, to hide the woofer assembly from view.
4. GRILL ATTACHMENT FITTINGS
The grill is attached to the main
assembly after the selector
switches have been set to the
desired positions.
