The pass-thru feature is also sometimes called loop out. This is included on some power amps (Musical Fidelity that I use has it on most of their power amps). The signal from the left output of the source component (preamp or Transporter, etc) feeds the first power amp via a single RCA cable. A second RCA cable then goes from the loop out of this 1st amp to the signal input of the second power amp. Similarly the right output from the source goes through the same set up with the 3rd and 4th power amps. The 4 power amps are then connected via speaker cable to the 4 pairs of input posts on the speakers. This cable can be four individual 2-core speaker cables or you can use special bi-wiring cable which has four conductors in each bundle. The 4 power amps do not need to be seperate monoblocs but can be a pair of stereo power amps, as long as at least one has the loop out sockets. Hope this helps clarify a bit. davep -- davep ------------------------------------------------------------------------ davep's Profile: http://forums.slimdevices.com/member.php?userid=61 View this thread: http://forums.slimdevices.com/showthread.php?t=28381 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
