High Level Connection
If the electronics in your system does not have Preamp Output/Power Amp Input connections, the ICS Sub 24 can be
connected via the speaker wiring using the “High Level” Connections. There are two methods for making high level
connections the ICS Sub 24.
The 5-way binding posts on the ICS Sub 24 permit easy connection to
banana plugs, spade lugs, and bare wire. If you are connecting bare wires
be sure to twist the wire strands into a neat bundle. Be sure there are no
loose strands that could touch another terminal and cause a short-
circuit.
NOTE:
When making high level connections be sure to maintain proper polarity - that is
c to + (positive) to (positive) and - to - (negative) to (negative). All wire has one of its
conductors marked in some way to make it easy to trace the connections. Typically there is a stripe
on the insulation or a rib molded into it. Or the insulation will be transparent and the wire strands of one conductor
will be copper colored and the other will be silver colored.
Preferred Connection Method
The preferred method for making high level
connections is to connect the speaker outputs of
your amplifier to the High Level inputs of the ICS
Sub 24, and then connect the main speakers to the
High Level Outputs. This is the best connection
method because the High Level Outputs are high
pass filtered - the low bass sound is removed. The
reduces the portion of the sound range the main
speakers must reproduce and makes it easier to
adjust the system for a smooth main speaker-to-
subwoofer transition.
