What is it? An 8-channel autoswitcher allowing the setting up of a redundant backup system by automatically switching between two sources such as dual digital recorders, computers or network systems. Details Designed primarily for live concerts and stage shows where backing tracks are used for orchestration, vocals and sound effects, SW8 employs an adjustable gate to detect a machine malfunction and automatically switches to a second 'backup' machine to deliver a seamless performance. A steady-state signal is recorded on a track and fed into the SW8. Should the signal drop, the SW8 will automatically switch to the B system and 'sound' an alarm. Switching can also be performed manually via the front panel A-B switch, a rear-access latching switch or by using the optional Radial JR2 footswitch. For larger systems, multiple SW8s may be linked together to create 16, 24 or 32 track systems. Housed in a heavy-duty steel rack enclosure, the SW8 is equipped with a choice of 25-pin D-sub or ¼" TRS connector inputs with both XLR and D-Sub outputs. The front-panel XLRs provide a balanced DI mic level to feed a snake system and are transformer-isolated to eliminate hum and buzz caused by ground loops. The rear-panel D-Sub provides direct balanced line level connectivity and the transformer isolated outputs may be internally re-patched to send the mic level signal to the 25-pin D-sub output if needed. And another thing... A global mute switch may be engaged to turn off the XLR outs, allowing audition and cueing of tracks on the fly. This is augmented by a standby switch that holds the SW8 on the source-A inputs in between songs.
