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 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.
