Sound does not come from one of the channels
Follow the steps below in order. If one of these steps succeeds in restoring the sound, stop there
and ignore the other steps.
1. Check speaker cable connections for the malfunctioning channel. Reconnect any cables that
may have become disconnected. Inspect the cables to make sure it they have not been damaged.
If a cable has been damaged, replace it.
2. Swap the interconnect cable from the preamp or surround processor to the amplifier's
malfunctioning channel with the cable for a channel that is functioning properly. If the
malfunctioning channel now works but the other channel does not, replace the defective
interconnect cable with one of the exact same type.
3. If using an analog source device, swap the left-channel interconnect cable from the source
device to the preamp with the right-channel interconnect cable. If the malfunctioning channel now
works but the other channel does not, replace the defective interconnect cable with one of the
exact same type.
4. Try using a different source device. If the alternate source device delivers sound in both
channels, it is likely the original source device is defective. Consult the manufacturer of that
source device or your dealer for further information.
5. If possible, try using a different preamp or surround processor. If the alternate preamp delivers
sound in both channels, it is likely the original preamp is defective. Consult the manufacturer of
the preamp or your dealer for further information.
6. If all of these steps fail to restore sound, consult your dealer for service.
Sound seems unclear or unfocused with stereo sources
Follow the below steps in order. If one of these steps fixes the problem, stop there and ignore the
other steps.
1. Play a CD or digital file (not a record) of a vocalist and sit in your usual listening position, which
should be equidistant from each speaker and typically 8 to 15 feet away from them. If the vocal
image appears centered between the speakers, they are connected correctly and your system is
probably operating properly.
2. If the vocal image is unfocused and the vocal seems to come from all the room, your speakers
are probably wired out of phase. Make sure that the speaker cables on your amplifier are
connected correctly. The cable connector marked + or colored red should be connected to the
speaker binding post with the red ring. The cable connector marked - or colored black should be
connected to the speaker binding post with the black ring.
3. If the sound is still unclear or unfocused, consult your dealer. Your system may have a setup
problem outside the scope of this manual.
