Introduction
Congratulations and thank you for your purchase of this professional, powered loudspeaker product. To get the most from your invest-
ment, we recommend you review all the information provided in this User Manual.
The HPR self-powered loudspeakers provide excellent sound quality, durable construction and clean, efficient, on-board amplification.
Amplifiers are matched to the drivers with active equalization and precise crossover control. Active power limiting and thermal man-
agement extends the life of drivers and the amplifier. The HPR series solves many application challenges with its great sound, built-in
protection systems and self-contained portability. HPR is the perfect solution for public performances, corporate events and private par-
ties demanding flexible and excellent sounding system solutions.
All models are self-powered using efficient amplifiers. AC line connection is fast and easy; an IEC-style quick-disconnect ensures reli-
able AC mains connection while providing an easy-to-remove power cord for cabinet mobility. Audio enters the self-powered loud-
speaker via a female XLR connector with an additional parallel-wired male XLR output for daisy-chaining. No outboard signal
processing is required as all models feature on-board filtering. The two-way and three-way full-range loudspeakers feature a switch-
able 100 Hz low-cut filter for use when subwoofers are part of the system. Subwoofer models have two full-range input connectors (left
and right) and two sets of output connectors; one pair featuring a 100 Hz low-cut filter and one pair passing full-range signal.
Rear-panel LEDs alert the user to AC power status, input signal presence, and instances of clipping. Additionally, a blue front-panel
“power on” LED provides valuable visual power confirmation. It can also be disabled for applications where light toward the audience
may interfere with stage aesthetics. All models feature a 21-step detent Gain control allowing precise control and repeatable setup.
The enclosures are made of high-quality plywood and are texture-coated in black. Features vary by model, so please refer to sales bro-
chures or the specifications section of this manual for specific model information.
