Description
- The SS 2.1 MLR/TERM is a transparent two input, dual output
switcher/router with mechanical latching relays.
- The SS 2.1 MLR/TERM is perfect for all types of passive
signal switching via front panel switches, contact closures
and/or serial RS-232.
- The 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.

- 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. TCP/Telnet

adapter.
- Two SPDT relay outputs for remote channel status.
- Internal silence sensor with front panel LED indicator;
separate SPST silence sensor alarm relay, adjustable alarm
delay and restore duration.
- Audio/signal switching via mechanical latching sealed relays
utilizing 2-form-C bifurcated - crossbar silver alloy with
gold overlay contacts.
- Removable euro-block screw terminal connectors are used for
audio/signal I/O and remote control connections. Necessary
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.
