Tell me more ×  I need to route sound from a personal computer
to one of a horde of monitors. Only one monitor will be active
at any one time, but I need to be able to switch between
monitors rapidly (<50ms) controlled by the computer.  For n <= 2
monitors, the solution is simple. The computer can output a mono
signal on channel 1 or 2, amplified through a standard stereo
amp. For n <= 5 speakers, likewise, with an appropriate sound
card and 5.1ch amp.  But what if I need to drive one of 10
monitors, or more? Of course, I could use, say, two M-Audio
Delta 1010LT PCI cards and two off-the-shelf 5.1ch amps. But
that seems wasteful, and impossible for n > 24.  In particular,
I was wondering: does there exist a device which can rapidly
route a single amplified output to one of n different monitors
-- based on an external control signal?  share|improve this
