terminal of your amplifier must be connected to the plus (+/red) terminal on the back of the S4/8, and the negative (-) terminal to the negative (-/white) terminal.

Using the high level inputs to feed the S4/8 power amplifier will not degrade the sound quality of either your loudspeaker or the subwoofer.

Line-level connections

As an alternative, you can use the low-level inputs on the S4/8. Using a high quality interconnect cable, connect your preamplifier’s output to the low level inputs on the subwoofer labeled PRE AMP IN.

We strongly recommend that you do not use single-ended interconnects longer than 10 feet (3.2 meters) to connect the preamplifier outputs to your subwoofer. On many preamplifiers, using an interconnect that is too long will negatively affect the performance of your preamplifier because of the high capacitance of the interconnect cable across the output of your preamplifier. This is why we provide balanced inputs on the S4/8. Balanced interconnects can be as long as you like.

If your preamplifier has only one set of balanced outputs and one set of unbalanced (RCA) type outputs, choose your first preference of connection for the amplifier that is driving your loudspeaker. Use the remaining set of outputs to feed the S4/8’s amplifier.

Do not connect BOTH single-ended and balanced inputs to the S4/8 at the same time. You could over-drive the built-in amplifier, and void the warranty.

Phase Switch

If the subwoofer is out of phase with the speakers they are used to augment, there will be some cancellation of the bass frequencies where they overlap. Some speakers are designed to be phase inverting (in particular those with 2nd order crossovers). There are also many power amplifiers that invert the phase of the incoming signal.

Because there are so many possible combinations, we recommend that you flip the switch between 0° and 180°. The correct position will be apparent from the greater amount of low-frequency output of your system.

If you have a phase inverting power amplifier and have inverted the phase on the subwoofer, AND you are using both line-level and speaker-level inputs, you must invert the phase of the speaker-level
