Product Overview

Radio Design Labs' ST-SX4 is a remote-controllable unbalanced audio source selector in the group of STICK-ON series products by Radio Design Labs. These products are designed for quick, convenient installation, and reliable operation in a variety of audio applications.

The ST-SX4 accepts up to 4 unbalanced audio sources. Any of these sources may be selected to feed the output, or all sources may be switched OFF. The output from the ST-SX4 is unbalanced. Control of the module is accomplished through a single input terminal. Connection of a specified resistance between the control input and ground causes the desired input to be switched ON. If no control input is connected, the ST-SX4 defaults to input 4. If the control input is shorted to ground, all inputs are switched OFF.

Use of a single-pair cable for control allows a minimum of wire to be installed. Installers may use a variety of remote switches; rotary, push button, toggle, etc. The three resistors are provided with the module. The ST-SX4 may conveniently be used with the ST-VCA2 to provide both remote switching and remote volume control. In this case, it is necessary to provide only a single-pair-shielded to control both modules (1 conductor to control the ST-SX4, 1 conductor to control the ST-VCA2, shield to provide control ground path). Two ST-SX4 modules may be used together for stereo switching.
