Location and Function of Controls
1. Input Grounding:
For most systems you can leave this jumper set in the BALANCED
position. In some systems, the source unit may look for a ground through the RCA connection
to the amplifier and create a ground loop, which can cause a whine. In this case, you should
change the four jumpers to the UNBALANCED position.
2. Ground Isolation Selector:
Occasionally alternator hiss 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.
Installation
A:-Placement & Mounting of the KEQ20
Placement : The KEQ20 needs to be installed in the signal path after your source unit but
definitely before your amplifiers and or any active crossovers. The chassis is usually mounted
in the rear of the vehicle close to the amplifiers as possible.
Mounting : Once you have selected a permanent mounting location, position the unit and mark
the appropriate mounting holes with a felt-tip pin or scratch awl. Before doing anything else,
make sure you are not about to drill a hole in a gas tank or piercing any existing wiring. Nothing
ruins your day more than an expensive repair bill. Drill a few small pilot holes and secure the
chassis of the KEQ20 with self tapping screws.
