The Radial SW8 is an 8 channel auto-switcher that allows you to set up a redundant backup system by automatically switching between two sources such as a pair of digital recorders, computers or network systems.

Designed primarily for live concerts and stage shows where backing tracks are used for orchestration, vocals and sound effects, the SW8 employs an adjustable gate to detect a machine malfunction and automatically switch to a second backup machine to deliver a seamless performance. Switching can also be manually performed using a remote latching switch or via the front panel A~B switch. For larger systems, the SW8 is easily linked using a standard ¼" guitar type cable. This enables the unit to expand to 16, 24 or 32 channels with all systems switching simultaneously.

Housed in a heavy duty 14-gauge steel 19" enclosure, the Radial SW8 is equipped with choice of 25-pin D-sub or ¼" TRS connector input sets. A third D-Sub provides straight through balanced output while the front panel is equipped with XLR outputs. Inside, eight Radial direct box transformers come factory assigned to the XLR outputs for easy patching from the stage to the mic splitter. The isolation transformers help eliminate hum and buzz caused by ground loops may be re-patched internally to the D-Subs if required.

The Radial SW8 eliminates embarrassing system malfunctions by providing an easy to implement and easy to use system that will ensure each and every show will go on!
