5. HIGH PASS OUTPUTS

Balanced XLR female connectors are provided for the left and right inputs. Connect the full-range line-level signal from the mixer or other signal source to these input jacks.

If you are connecting a single subwoofer output, or LFE (low-frequency effects) output to the subwoofer, you may use either the A or B input connector.

CAUTION: NEVER connect the output of

an amplifier directly to the input of the

subwoofer. This could damage the input circuitry of the active subwoofer.

4. FULL RANGE OUTPUTS

Balanced XLR male connectors are provided for the line-level A and B full-range outputs. Connect these outputs to the inputs of another powered subwoofer, main powered loudspeakers, or to an amplifier powering passive loudspeakers.

The signal at these outputs is a direct copy of the input signals. These outputs allow you to daisy-chain multiple subwoofers, and/or send the full-range signals to the main loudspeakers.

The level control and polarity switch have no effect on the full-range outputs. The outputs are separate and maintain the stereo separation of the input signals.

Balanced XLR male connectors are provided for the line-level A and B high-pass outputs. The subwoofer’s internal active crossover splits the input signals into two frequency bands. The low frequency range below 125 Hz goes to the internal amplifier that powers the subwoofer. The frequency range above 125 Hz is sent to these line-level output jacks.

Connect these outputs to the inputs of your main

powered loudspeakers, or to the inputs of the amplifier powering the main loudspeakers. In this way, the main loudspeakers will play the range above 125 Hz. If the main loudspeakers have good low-frequency response, then you may decide to use the full-range outputs [4] instead.

The level control and polarity switch have no effect on the high-pass outputs. The outputs are separate and maintain the stereo separation of the input signals.

6. POLARITY

This switch reverses the polarity of the signal going into the subwoofer amplifier by 180°. It has no effect on the signal at the line-level outputs.

There is no right or wrong setting for this switch. Listen to the overall blend of the subwoofer with the rest of the system and select the switch position that gives you the best sound for your audience. In fact, your system may vary when positioned differently and in alternate venues. Don’t be afraid to experiment with the position of the polarity switch. See page 11 for more information.
