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.
