UNDER THE COVER
Beside all of the clever buttons on the outside of
your DQT, there are a few factory preset functions,
located under the cover, that assist in maximizing
the performance of your DQT. To access these
jumpers you will need to remove the 4 each top
screws and carefully lift the chassis top. You will
note that there is a ribbon cable that connects the
display, mounted on the chassis top, to the main
circuit board. Once under the cover, you will
access to the following jumpers:
1. Input Grounding: For most systems you
can leave this jumper set in the BALANCED
position. In some systems, the amplifier may look
for a ground through the RCA connection to the
source unit and create a ground loop, which in
turn can cause a whine (not the type that comes
in a bottle) in your system. In that event, you
should go ahead and change the jumper to the
UNBALANCED position.
2. Ground Isolation Selector: Occasionally
alternator noise may appear in a system because
the source unit and amplifier are using different
grounding schemes. To help in this situation, we
have provided alternative grounding connections.
Make sure your system is turned OFF before you
move these jumpers.
