Broadcast Tools SS 2.1 III 2 Channel Balanced Stereo Audio Switcher *NO SERIAL* [Used]

Broadcast Tools SS 2.1 III • Stereo Balanced Audio Switcher • Automation Controlled RS-232 Switcher • With Power Supply and Serial Cable

Used, in good cosmetic condition. In my testing I was unable to obtain a response to commands sent to the RS-232 Serial port. Please assume that the serial input does not work. It does respond to front panel button presses as expected. Other methods of control have not been tested and should be assumed to be unsupported. With 9V DC/115V AC Power Supply. No unpictured cables, accessories or documents are included.

Description

• The SS 2.1 passively switches or routes a variety of electrical signals to a destination.
• The SS 2.1 selects any one of 2 stereo inputs to a single stereo output.
• The SS 2.1 provides PASSIVE switching through gold contact relays. The passive switching means that the unit can route a signal in either direction (any one of 2 stereo inputs to a single destination, or a single source to any one of 2 destinations).
• Due to the passive nature of the switching, any input level and impedance can be used. Inputs may be balanced or unbalanced, while output levels,impedance, distortion, noise and balancing will match that of the selected input.
• In addition to the normal use with audio signals, the unit can also be used to switch digital signals and telephone lines.
