Page 6: Installation
How They Should Be Used HPR122i: The HPR122i was designed to sit on the floor, stage, subwoofer enclosure, be suspended, or be pole mounted on a 35mm diameter loudspeaker support pole. The pole can be part of a stand-alone loudspeaker stand or be inserted into the pole cup of the HPR151i or HPR181i. - Page 7 The HPR152i and HPR153i enclosures feature three load-rated pick points. HPR122i The HPR122i enclosure features nine load-rated pick points. As shipped from the factory, each pick point has a bolt or plug installed to retain the air-tight design of the enclosure. Never operate the loudspeaker with the pick points open (unsealed) as it will degrade the performance of the product.

Page 8: Power Switch
Power On Sequence: Turn on all source devices (CD players, mixers), turn on subwoofer, then turn on the “top-boxes” (HPR122i, HPR152i and HPR153i). Power Off Sequence: Turn off the top-boxes, turn off the subwoofer, then turn off the source devices. -
Page 9: Input Connections
11k ohm for unbalanced connections. The signal's source impedance should be less than 600 ohms. HPR122i, HPR152i and HPR153i: Insert the male XLR input Subwoofer loudspeaker’s Input (IN) into the jack marked FULL RANGE LINE IN. Ensure the connector and Output (OUT) Connectors is fully seated. -
Page 10: Output Connections
IMPORTANT! If using full range loudspeakers from another manufacturer, we recommend they be connected to the QSC subwoofer’s 100 Hz LOW- CUT OUT. This will ensure proper phasing of the full range loudspeaker with respect to the sub-... -
Page 11: Gain Control
This results in proper subwoofer operation and allows the top box to provide improved clar- ity in the middle and high frequencies. HPR122i: If using as a floor monitor, turn the filter ON for improved vocal range clarity and to reduce low frequency build-up on... - Page 12 How to Use the Polarity Switch When using QSC subwoofers and QSC full range loudspeakers, NORMAL polarity will result in the best bass response IF the full range loudspeakers are sitting on or very close to the subwoofers. If the subwoofers are some dis- tance away from the full range loudspeakers, polarity change may be of bene- fit.

Page 13: Normal Indication
SIGNAL Indicator LED The green SIGNAL indicator alerts the user to the presence of an input signal to the HPR loudspeaker. Normal Indication The green SIGNAL indicator illuminates when the input signal exceeds -25 dB. If No Indication LED indicators. Check Gain settings and increase gain if necessary. -
