Snell Acoustics ICS Sub 24 owner manual High Level Connection

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 connect + 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

Amplifier, Receiver or Preamp/Power Amp

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.
