ARX QS-1 Q-Switch Quad Channel 4x1 or 1x4 Stereo Audio Switcher
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.

Its innovative precision design allows the Qswitch to be used in two modes:
1x4 for sending any one of 4 sets of Powered Loudspeakers, Sub Woofers etc, or
4x1 for selecting any one of 4 signal sources to one output in Broadcast, Installation, Studio applications.
