POLARITY

0°

180° POLARITY
THX = 0˚

This switch reverses the polarity of the signal going to the subwoofer amplifier by 180º. It has no effect on the signal at the LEFT and RIGHT OUT or the MASTER OUT.

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.

LEFT AND RIGHT INPUTS

Balanced XLR female and unbalanced RCA female connectors are provided for the left and right inputs. Connect the full-range line-level signal from the mixer or preamplifier to one of these input jacks.

The connectors are wired as follows (per the AES/IEC standard):

 

XLR

RCA

Hot (+)
Pin 2
Tip
Cold (–)

Pin 3

Shield (Ground)

Pin 1

If connecting a single subwoofer or LFE output to the HRS150, use the LEFT (MONO) input with the FILTER BYPASS switch pushed in.

LEFT AND RIGHT OUTPUTS

Balanced XLR male and unbalanced RCA female connectors are provided for the line-level left and right high-pass outputs. Connect these to the inputs of the main speakers (if they are powered speakers) or to the inputs of the amplifier powering the main speakers.

The signal at the left and right outputs is post-crossover. The low-pass output from the crossover goes to the internal power amplifier in the HRS150, while the high-pass output goes to these output jacks.

CROSSOVER

THX = 80 Hz

This adjusts the crossover frequency for the built-in 24 dB/octave Linkwitz-Riley variable crossover. The crossover frequency can be adjusted from 55 Hz to 110 Hz.
