1. Output Summing Jumpers:
Some factory installed audio systems
include separate amplifiers that output limited bandwidth signals
that are actively crossed over and are connected directly to
tweeters, midranges, and/or woofers. For optimum performance
you will want to combine (or sum) these separate signals into a
single full range signal. The DQ-61 facilitates this internally via
simple jumper settings that allow you to select which input sig
-
nals will be summed into the Front/Main outputs. An additional
feature is that once you move the Summing jumpers to SUM, the
audio signal coming from the Main Output will also come out of
the Channel 2 Output. When the jumper is moved to the “SUM”
position for a selected channel, the corresponding indicator LED
on the front of the DQ-61 will turn green The shipped-from-the-
factory setting is in the OFF or non-summed position.
2. AutoMode:
Some cars have low-level or other unusual signals
on their speaker leads that may not trigger the AutoMode circuit
and result in signal switching. If this occurs you can move the
internal AutoMode jumper to “OFF”.
3. GTO™ Signal Sense:
In some situations, factory installed audio
systems may turn ON or “wake up” due to convenience features
like doors chimes, alarms, and cell phone signals triggering the
source. To prevent these from turning your audio system on
unexpectedly, you can bypass the GTO™ circuit by moving the
GTO™ jumper to “OFF,” and use a switched 12-volt signal con
-
nected to the Remote In terminal instead. The DQ-61 ships the
GTO in the “ENGAGE” position.
4. Ground Isolation Selector:
Alternator noise may appear in a sys-
tem because the source unit and amplifier(s) 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. We ship them in the
isolated position, which usually gives the best results.
