Key Features
- Instant noiseless switching between backing-track playback systems
- Auto, manual, and remote switching options for diverse operation
- Thru-puts both line-level and mic-level signals for easy interfacing
- Link function easily accommodates larger playback systems
Radial SW8 8-Channel Auto-Switcher Overview
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 artist's 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.

View Full DescriptionFeatures
- 8-channel auto-switcher that allows you to set up a redundant backup system
- Works by automatically switching between two multi-channel playback systems
- Designed primarily for live concerts and stage shows where backing tracks are used
- Employs an adjustable gate to detect a machine malfunction and automatically switch to a second backup machine to deliver a seamless performance
- Monitors and continuous audio signal such as SMPTE on the main playback system, and sohuld the signal drop, it will auto-switch to the backup
- Switching cn be carried out manually on the front panel, or using a Radial JR2 footswitch (not included, must be purchased separately)
- For larger systems beyond 8 channels, multiple SW8s can be linked together
- Global pad attenuates the signal going to the XLR direct box outputs by -20dB to prevent transformer saturation
- Set the gate input sensitivity on the front panel to determind when the SW8 should auto-switch
- Mute switch turns off the XLR outputs, leaving the balanced D-Sub output on for local monitoring
- Standby switch allows you to hold the auto-switching on inputs-A so that the SW8 won't switch to inputs-B whilst waiting for a drone signal
- Alarm LED on the front panel illuminates 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 is used to send the 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 that lets you use a binary signal such as SMPTE as a drone track by smoothing out the signal
- Internal relay that 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
