One or more channels produce only bass, no mid or treble
Follow the below steps in order. If one of these steps fixes the problem, stop there and ignore the
other steps.
1. If you have changed the crossover adjustments on the Master Power series amplifier from the
original factory settings, open the control cover on the rear panel and make sure that the sliding
switches on the lower half of the control panel for the channels powering your main speakers are
all centered (for full-range speakers) or flipped to the left (for smaller speakers used with a
subwoofer).
2. If you are using the Master Power series amplifier to biamplify or triamplify a speaker, make
the cable between the amplifier and the highest set (or highest two sets in a triamplified
arrangement) of binding posts on the speaker is firmly connected.
3. If you are using the Master Power series amplifier in a biamp/triamp configuration, make sure
the bus switches behind the control cover on the rear panel are set correctly. Refer to page 8 for
more information about these.
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 (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.
