Broadcast Tools Universal 4.1-MLR-SERIAL

4ch passive switcher/router with AES/Analog stereo XLR and StudioHub I/O


The Universal 4.1 MLR/Serial is a transparent four input, one output switcher/router with mechanical latching relays designed to pass AES or stereo balanced signals. The Universal 4.1 MLR/Serial is perfect for all types of passive signal switching via front panel switches, contact closures, logic or USB or RS-232 Serial remote control. Each input features stereo female Neutrik XLR and StudioHub+ RJ45’s connectors. The output features stereo male XLR and StudioHub+ RJ45 connectors. Switching is accomplished via mechanical latching gold contact relays, which means that the unit can route a signal in either direction and will keep routing signal even after losing power. 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.
