QSC Audio HPR181W, HPR153F, HPR151W, HPR152F user manual Application Example #4

Application Example #4

This example shows a two-channel (stereo) setup utilizing two sub- woofers and multiple top-boxes.

This is the same as Application Example #3 except an additional top-box has been added to each channel (and more could be added).

To connect to additional top-boxes, connect a cable from the last top box’s FULL RANGE LINE OUT con- nector to the next top-box’s FULL RANGE LINE IN connector. Up to 20 top-boxes could be “daisy-chained” without degrading signal quality.

Channel 1

or

Left Channel

Channel 2

or

Right Channel

Use only high-quality balanced cables for interconnecting the audio equipment.

Ensure the top-boxes have their 100 Hz LOW-CUT FILTER switched on when connecting to the subwoofer’s FULL RANGE LINE OUT as a signal source.

Also, be sure to use either the Left or Right (marked L or R) on the subwoofers. If the subwoofer’s input is connected to the Right (R) channel connec- tor and the output to the top-boxes is connected to the Left (L) channel connector, no signal will reach the top-box (no sound from the top-box).
