INSTALLATION

STEP 4: MOD 111 MODULATOR SETUP

LOCATION

The Modulator is usually located with the sound system amplifier or mixer for easy access to

an audio input signal. For portable systems, the modulator can be placed near the emitter or

in another convenient location. (The SS-6 Stand Kit is available for portable systems.)

Step 2: Plug the power supply into an AC outlet.

BASEBAND CABLE CONNECTION

The MOD 111 drives one emitter. The TX8 repeats the baseband signal, so any number of

emitters can be used. The modulator outputs CANNOT be split with CATV splitters.

AUDIO CONNECTION

The MOD 112 accepts audio signals from industry-standard low impedance microphones,

balanced lines, and unbalanced lines.

are used for the mic input only.
