Q. I’m having difficulty transmitting a digital optical signal about 75 ft. from a remote Dish satellite receiver to an A/V Home Theater receiver. I’ve added a Toslink repeater/amp device, but to no avail. Do you have any suggestions? â€“ George.
A. Thanks for your e-mail and interesting question.
I suspect the optical pulses are much too weak, even with the Toslink repeater/amp device. I quizzed Axiom’s chief engineer, Tom Cumberland, who stated that a normal plastic fiber-optic link is only good for about 6 to 10 feet. Over longer distances, the plastic fiber-optic link causes the pulses to â€śblur,â€ť so the optical receiver in the AV receiver canâ€™t distinguish between the â€śonâ€ť and â€śoffâ€ť optical pulses that relay the digital code.

Q. So here may be the dumbest idea you have heard all week. I am a confirmed 2-channel guy. I recently bought an Axiom subwoofer that I plan to use only when watching movies. I have been toying with the idea of going â€śall the wayâ€ť and setting up a 5.1 system to use separately from my 2-channel system when watching movies. I want to continue to use my existing 2-channel preamp and amp when listening to music. It seems silly to buy new main speakers when I have my existing speakers. I am trying to figure out a way to share my main speakers between a 2-channel setup and a 5.1-channel setup. Itâ€™s not possible (is it?) to run 2 amps (2-channel and 5.1- channel) into one speaker as long as only one amp is powered up at a time (two sets of speaker cables to each speakerâ€™s binding posts)? Would this cause a short? I am trying to avoid having to switch speaker wires back and forth every time I want to switch from movies to music. If this is a really silly idea, can you think of any other workarounds? â€“ Mike Log in

Q. I have a Yamaha PianoCraft-E810 Micro Component System that uses its original manufacturer’s speakers. Its specifications are: 55W+55W Minimum RMS output power per channel (6 ohms, 1 kHz, 0.1% THD). My problem is that the system plays well, but as soon as I try to raise the volume (not even reaching the halfway mark of the volume dial), it cuts out and automatically switches off. Do you have any clue as to what the problem could be? â€“ A.M Log in
