Sound comes from only one channel
Follow the below steps in order. If one of these fixes the problem, stop there and ignore
the others.
1. Check to make sure the power meters on the amplifier is illuminated. If the amplifier’s meter
is not illuminated, follow the troubleshooting steps under “Amplifier will not power up”
to restore power to that amplifier.
2. Check speaker cable connections for the malfunctioning channel. Reconnect any cables that
may have become disconnected. Inspect the cable to make sure it has not been damaged.
If it has been damaged, replace it.
3. Swap the left-channel interconnect cable from the preamp to the amplifier 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. You may
have to replace both cables to make sure they match.
4. 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. You may have to replace both cables to make sure they match.
5. 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.
6. If possible, try using a different preamp. 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.
7. If all of these steps fail to restore sound, consult your dealer for service.
Sound seems unclear or unfocused
Follow the below steps in order. If one of these fixes the problem, stop there and ignore
the others.
1. Play a CD (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 are connected
correctly. The cable connector 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.
