The Broadcast Tools SS 2.1 MLR/RJ is a transparent two input, one output stereo RJ45 audio switcher/router with mechanical latching relays. The SS 2.1 MLR/RJ is perfect for all types of passive signal switching via front panel switches, contact closures and/or RS-232 serial commands. Switching is accomplished via 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.
