Lightly Used • Tested/Guaranteed • Broadcast Automation Switcher/Router • RS232 Control • With 115V AC Power Supply & Serial Cable

Lightly used. Tested to confirm correct operation. Very good cosmetic condition. Includes 115V power supply and serial cable. No printed manual is included but it may be downloaded from https://www.prostudioconnection.net/2105/Manual_SS2x1_MLR-TERM.pdf. This is a multiple item listing so there will be very small non-performance affecting differences between units.

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.
