ELECTRICAL INSTALLATION
Note:
Observe all local and national codes when
installing the loudspeaker.
The loudspeaker 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 loudspeaker.
2. Connect the GND terminal on the amplifier to the
IN – connection on the loudspeaker.
3. Select the appropriate power tap on the
loudspeaker 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 loudspeaker.
2. Connect the GND terminal on the amplifier to the
IN – input connection on the loudspeaker.
3. Select the appropriate power tap on the
loudspeaker, 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 loudspeaker. This amplifier also uses a screw-
terminal output.
1. Connect the A + terminal on the amplifier to the
IN + input connection on the loudspeaker.
2. Connect the A – terminal on the amplifier to the
IN – connection on the loudspeaker.
3. Select the "direct" position on the loudspeaker
to bypass the power-tap transformer and run the
loudspeaker as a constant impedance loudspeaker
(8 ohm nominal).
