The Broadcast Tools SS 2.1/Term passively switches or routes a variety of electrical signals to a destination.
The SS 2.1/Term III selects any one of 2 stereo inputs to a single stereo output. The SS 2.1/Term III 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 signals and telephone lines.
– Two operational modes, Normal and EAS control emulation via contact closures or serial RS-232.
– Operational control by front panel switches with LED indicators, contact closures, 5-volt TTL/CMOS logic levels and/or the multi-drop RS-232 serial port.
– Removable screw terminals (Euro) are provided for audio and remote control connections.
– Audio switching via sealed relays utilizing 2-form-C bifurcated-crossbar silver alloy with gold overlay contacts.
– Logic functions via microprocessor and non-volatile memory.
– The power-up feature allows the user to select which one source is active at power up, including the last source selected.
– Configuration via dip switches.
– The ENABLE switch provides a safety lock to the front panel source selection switches.
– The audio MUTE switch allows the user to turn off the audio output when activated.
– Source number one is configured to route audio to the output in the case of loss of power to the unit.
– Non-selected sources are terminated with 10K ohms, load resistors.
– Relays provided for remote status.
– The SS 2.1/Term III may be set on a desktop, mounted on a wall or as part of the new RA-1, Rack-Able mounting shelf.
Optional: RA-1 rack shelf for mounting up to three units in 1-RU.
– Automation source switching
– EAS audio switching or any type of stereo, monaural, composite audio
– AES/EBU, ISDN, RS-232/422/485, telephone line switching
– Multiple station music on-hold and/or PA switching.
