The Broadcast Tools SS 4.1 PLUS passively switches or routes a variety of electrical signals to a destination. The SS 4.1 PLUS selects any one of four stereo inputs to a single stereo output. The SS 4.1 PLUS provides PASSIVE switching through gold contact relays. The passive switching means that the unit can route a signal in either direction. 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 their normal use with audio signals, the unit can also be used to switch AES/EBU digital signals and telephone lines.

Main Features:
• Operational control by front panel switches with LED indicators, contact closures, 5-volt TTL/CMOS logic levels and/or the multi-drop bi-directional RS-232 serial port
