Broadcast Tools SS 2.1 MLR/Term

 

The SS 2.1 MLR/Term is a transparent two input, one output (2×1) switcher/router with mechanical latching relays and pluggable euroblock screw terminals. The SS 2.1 MLR/RJ is perfect for analog or digital audio or other types of passive signal switching via front panel switches, contact closures and/or serial RS-232.

Switching is accomplished with mechanical latching gold contact relays, which 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. The SS 2.1 MLR/Term can be controlled and monitored locally and/or with simple contact closures to ground, as well with multi-drop RS-232 serial commands.

Features/Benefits

  • • Front panel channel selection push buttons with active channel LED indicators.
  • • The audio “MUTE” function allows the user to turn off all audio.
  • • Front panel Enable switch can be configured to provide a safety lock to the front panel selection push buttons.
  • • Remote control via contact closures, 5-volt TTL/CMOS logic levels and/or the multi-drop RS-232 serial port.
  • • Internal silence sensor with front panel LED indicator, open collector output with adjustable alarm delay and restore duration.
  • • Two SPDT relay outputs for remote channel status.
  • • Audio/signal switching via mechanical latching sealed relays utilizing 2-form-C bifurcated – crossbar silver alloy with gold overlay contacts.
  • • Removable screw terminals are used for audio and remote control/status to simplify wiring and service. Euroblock mating plugs are supplied.
  • • The power-up source selection feature allows the user to select which source is active at power up, including the last source selected.
  • • If power is lost, the last selected channel is passed to the output.
  • • Fully RFI proofed.
  • • Surge protected internal power supply, power adapter with domestic connector supplied. International power supply optional.
  • • Up to three units may be mounted on the optional RA-1 rack shelf. Desk top and wall mounting is also possible.
