Cross-over
The bi-amplified HPR152F and tri-amplified HPR153F are "active" systems. There are two advantages to an active system.
Advantage 1: With a conventional passive speaker system, a single amplifier channel covers the entire frequency spectrum. So, when a bass note overdrives an amplifier, the resulting clipping produces harmonics that also go to the mid and high-frequency drivers. The result is audible distortion or, worse yet destruction of the drivers. In bi/tri-amplified systems, only the low-frequency amp would produce distortion while the mid and high frequency amps continue to deliver clean, undistorted sound.
Advantage 2: Active systems allow far more extensive tailoring of the cross-over response than is possible with passive cross-over networks. The two and three-way HPR models include crossovers that maintain coherent performance across the transition between low, mid and high-frequency drivers.
In addition, these models incorporate a unique, 100 Hz Low-Cut filter. This opens up powerful mixing possibilities. One subwoofer or many, the HPR subs have crossover functions for any application. The subs' stereo inputs sum the left and right inputs to mono while also giving you a stereo output for a pair of mid-high speakers.
Professional Good Looks and Tour Grade Tough
Rugged 13-ply birch enclosures
The HPR Series loudspeakers are meant to travel and are constructed of premium quality 13-ply birch coated with a tough, professional sprayed finish. Carefully engineered bracing keeps the enclosures rigid for tight, accurate low-frequency performance.
Tour-grade 16-gauge steel grilles
The attractive, powder coated 16-gauge steel grille is built tough to withstand anything that you can throw at it. If you look closely, you can see the slight concave shape of the grille which goes even further to keep it rigid.
Amplifier module
The amp module is constructed using a large heat sink with ample radiating surface so your HPR speakers won't shut down just when the show gets hot. Another example of QSC's attention to details is the beveled edges of the heat sink fins. Sharp edges have been milled off to prevent injuries to users and their gear.
Transport
Rolls with the greatest of ease
Heavy duty 3" wheels on the back of the HPR181i roll easily over cables, thresholds and other obstacles.
Ergonomic handles with comfortable non-slip grip
QSC designed and tooled an ergonomic handle with a comfortable, no-slip grip. Every time you pick up your HPR speaker, you'll be reminded of QSC quality and attention to detail.
Leave the light on... or off
With the HPR Series, you have the option of turning the grille-mounted LED off for situations where it would be distracting.
Going that extra mile
Before any QSC product gets its final approval, it has to pass a multitude of grueling tests. If we can find a way to break it, we will and we'll engineer a fix so it doesn't happen to you. That's what going the extra mile means, more testing, better quality components and a commitment to making the best products possible. Professionals rely on QSC gear every day because it doesn't let them down. |
