Introduction
Congratulations and thank you for your purchase of this professional, powered loudspeaker product. To get the most from your investment, 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. Amplifi-
ers are matched to the drivers with active equalization and precise crossover control. Active power limiting and thermal management 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 parties 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 reliable AC
mains connection while providing an easy-to-remove power cord for cabinet mobility. Audio enters the self-powered loudspeaker 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 fea-
ture on-board filtering. The two-way and three-way full-range loudspeakers feature a switchable 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 fea-
turing 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 limiter operation. 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 enclo-
sures are made of high-quality plywood and are texture-coated in black. The models HPR122i, HPR152i and HPR153i have integral M10 suspen-
sion points for permanent installation and "flying" applications. Features vary by model, so please refer to sales brochures or the specifications
section of this manual for specific model information.
