The SA-1422 is the complete solution for a wireless infrared listening system. The SA-1422 continues Sound Associates' reputation for quality wireless products with a device designed to meet the needs of the most demanding client. This transmitter utilizes a high speed DSP to control audio processing, audio level, frequency modulation and output power.

A high intensity 20 character LCD display shows audio metering and channel settings while simple front panel controls allow for easy access to menu options.
