Telex ST-300 17-Channel Synthesized Base Transmitter

The Telex ST-300 base transmitter features 17 user selectable frequencies controlled by front mounted control buttons and LCD display, a headphone jack with adjustable level for input signal monitoring, and a peak reading on the LCD display for visual input monitoring. On the back of the unit is a balanced XLR-3F with selectable mic, line, and 70 volt input options, as well as an unbalanced 1/4" input. The input selection and attenuation is all done from the controls on the front panel, no special tweaker required.
