Make your life easier with the Radial SW8 8-Channel Auto-Switcher. This is an 8-channel redundant backup auto-switching interface. It is an indispensable tool for any performance where pre-recorded backing tracks are part of the artists sound providing you with a handy device that will automatically and seamlessly switch between two playback systems should one malfunction.
Switching can also be carried out manually from the front panel or remotely via a JR2 footswitch (not included). You’ll find switching instant. There’s no signal degradation or interference so the show will go on uninterrupted. The SW8 features a link function that enables you to slave several units together for larger track-count playback devices with no detrimental effect to the unit’s switching capabilities. The SW8 is easy to interface using line-level thru-puts and transformer-isolated XLR direct outputs for flexible use of both line-level and mic-level signals.
The features of the Radial SW8 8-Channel Auto-Switcher include:
– 8-channel auto-switcher that allows you to set up a redundant backup system
– Automatically switches between two multi-channel playback systems
– Designed primarily for live concerts and stage shows where backing tracks are used
– Adjustable gate detects machine malfunction and automatically switches to a backup machine for seamless performance
– Monitors and continuously audio signal such as SMPTE on the main playback system and switches to backup if signal drops
– Switching can be carried out manually on the front panel or using a Radial JR2 footswitch
– Multiple SW8s can be linked together for larger systems beyond 8 channels
– Global pad attenuates the signal going to the XLR direct box outputs by -20dB to prevent transformer saturation
– Gate input sensitivity can be adjusted on the front panel
– Mute switch turns off XLR outputs and leaves balanced D-Sub output on for local monitoring
– Standby switch holds auto-switching on inputs-A to prevent switching to inputs-B while waiting for a drone signal
– Alarm LED illuminates on the front panel when the tone signal falls below the set threshold level
– Ground lift switch disconnects pin-1 on the XLR output to reduce noise caused by ground loops
– Balanced low-Z transformer-isolated direct box outputs
– Two sets of eight balanced or unbalanced line-level inputs for the primary and backup systems (A and B)
– Balanced line-level D-Sub output sends active input set (A or B) to the PA or local monitoring system
– Balanced line-level A and B D-Sub inputs are used for connecting two multi-track playback units to the SW8
– Filter allows the use of a binary signal such as SMPTE as a drone track by smoothing out the signal
– Internal relay can turn on a siren or beacon when the drone signal drops below the set threshold
– Legendary Radial construction ensures incredible durability and reliable operation
