The QR36 is a modular 2-way column loudspeaker to be used as vertical array, either in stacked or flown configuration, for both permanent and (limited) portable installations. It combines the ease-of-use handling of a conventional system, with the throw of a line-array system.
As an “array of line-sources”, a QR system acts as true cylindrical radiator, offering a 3dB SPL drop-off per doubling of distance (in the “near-field” or “Fresnel-zone”). This brings significant advantages in SPL coverage and (intelligibility) throw, from a relatively simple system.
Featuring double RBN1801 pro-ribbon drivers (patents pending), the QR36 offers Real-90 horizontal dispersion with seamless coverage; Its transient response and high peak power handling enable an amazing intelligibility and throw.
The 91% active frontal radiation, in combination with the pro-ribbon’s all-natural cylindrical flat (Isophasic) wavefront, brings maximum “gain-before- feedback” up to directly in front of / under the cabinet.
The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the QR36 and ALC. In this way, the ALC can be loaded down to 2 ohms, without any sacrifice on response quality (2 units QR36 parallel on one channel loads 3 ohms).
The system includes dedicated filtering, but system equalizing is done remotely (electronically) fully utilizing the individual speaker components’ power capacity; In combination with the unusual high peak power handling (6000W/200mS), this results in a virtually infinite headroom SPL from 1kHz.up.
Typical applications for the QR-systems include main system for theatre, PA system in “acoustically challenging rooms”, as well as high power side-fill stage monitoring.
For full system performance, the QR36 needs to be driven by an ALC amplified loudspeaker controller. Driven by the ALC, the QR36 delivers maximum sound quality with inaudible (power and excursion) protection.
