4.5 Connecting Preamplifier to the Amplifiers

The Sentinel subwoofer section is actively powered by its own subwoofer amplifier, whereas the upper speaker section is powered by your own amplifier that is directly connected to the Sentinel crossover cabinet. Therefore, you will need to make two separate output connections from your preamplifier. This is accomplished in one of the following three methods:

1. Interconnect Y-cable at the preamplifier

Ahigh-quality interconnect Y-cable may be the method with the least amount of signal loss. Simply connect Y-cables directly at the preamplifier's left and right channel outputs to divide the signals, resulting in two left channel outputs and two right channel outputs. Then route one set of divided outputs (right and left channel) to the subwoofer amplifier, and the other set (right and left channel) to your own amplifier.

2.Two outputs at the preamplifier

Some preamplifiers are equipped with two sets of outputs. In this case, you may simply connect one set of outputs (right and left channel) to the subwoofer amplifier, and the other set of outputs (right and left channel) to your own amplifier. If the preamplifier inverts the phase of one of the outputs, be sure to compensate by reversing the polarity of the speaker leads at the corresponding amplifier's output terminals.

IMPORTANT: Correct polarity of connections is critical to performance. Check to insure that the polarity is correct at the amplifier and crossover cabinet terminals.

3. Loop-Out from the Subwoofer Amplifier

The Sentinel Subwoofer amplifier is also equipped with loop-output connectors that bypass the amplifier's circuitry. Utilizing this feature, you may connect directly from these subwoofer amplifier loop-outputs to the inputs of your own amplifier.

WARNING: Failure to follow the set-up and wiring instructions explicitly may cause damage to your loudspeakers and void your warranty.

FAQ

What are the three methods for connecting my preamplifier to the amplifiers?

The three methods are using an interconnect Y-cable at the preamplifier, using two outputs at the preamplifier, or using the loop-out from the subwoofer amplifier.

What should I do if my preamplifier inverts the phase of one of the outputs?

If the preamplifier inverts the phase of one of the outputs, be sure to compensate by reversing the polarity of the speaker leads at the corresponding amplifiers output terminals.

What is the importance of correct polarity of connections?

Correct polarity of connections is critical to performance. Check to insure that the polarity is correct at the amplifier and crossover cabinet terminals.
