Williams Sound MOD 232 specifications Two Channel Infrared Modulator Model MOD, Description

Two Channel

Two Channel Infrared Modulator • Model MOD 232

D

Description:

The MOD 232 Modulator is designed to operate with a TX9 emitter operating on 2.3/2.8/3.3/3.8 MHz frequency. Each microprocessor controlled MOD 232 modulator can handle up to two audio channels. Baseband outputs can daisy-chain two MOD 232 together for four-channel operation. Flexible combi- nation jacks permit balanced/unbalanced line-level inputs. Carrier frequencies are controlled by the microprocessor and a frequency synthesizer for rock-solid frequency control.

Applications:

• Churches • Schools • Auditoriums • Conference Rooms • Theaters
