The Qswitch is a Quad Channel Stereo Switcher; a new addition to our popular AudiBox range of precision audio tools. What does it do? With this useful device you can: Switch any of FOUR stereo inputs to ONE stereo output, OR Switch ONE stereo input to any of FOUR stereo outputs. Careful user-friendly annotation makes it easy to understand and to see which input or output is being switched. A bank of four latching interlocked switches mean you can only select one switch at a time. A 'scribble-strip' lets you write above each switch with a Chinagraph? or grease pencil, so you can easily confirm what is being switched.
