SoundMate Personal Listening System includes:
- one ST-300 17 Channel Base Transmitter
- four SR-50 single channel receivers
- four SEB-1 single earbud earphones
- wall plaque
- UL & CSA approved wall pack transformer
- one 1/4 wave telescoping antenna
The ST-300 Base Transmitter features 17 user selectable frequencies digitally controlled from the front panel control buttons, a headphone jack with adjustable level for input signal monitoring, and a backlit LCD display that shows Channel, Frequency, and Audio Input Level. On the back of the unit is a balanced XLR-3F as well as an unbalanced 1/4" input. Front panel controls and LCD display allow the user to select mic, line, and 70 volt input options, attenuate the input levels and change hi/low RF transmit power. A feature called Enhanced Dynamic Range (E.D.R.) works with the SR-400 receiver to provide clearer more dynamic audio.
