QR24 Column Loudspeaker

QR24 Column Loudspeaker

The QR24 is a modular two-way column loudspeaker for use in vertical array systems (permanent and limited portable applications).

It combines a natural, dynamic sound reproduction with intelligibility even in acoustically challenging environments. The symmetrical acoustic design, in combination with the horizontal dispersion of the RBN HF drivers, offers horizontal pattern control. This widens the "stereo sweet spot" for the off-axis-positioned audience.

By using just two RBN drivers, the system's active frontal radiation produces controlled vertical dispersion. This controlled (cylindrical) projection can be extended down to the lower frequencies by enlarging the array length via extra QR/QM modules (extending the "near field").

The passive filtering enables multiple modules to be combined on one amplifier channel with up to three units.

Each purpose-designed 12-inch RBN driver has a peak power handling of 2.000W (200 msec), creating a system headroom of 4.000W from 1kHz up. Together with the high acoustical output, the system enables high-SPL sound-reinforcement performance.

The QR24 is powered and controlled by the ALC amplified loudspeaker controller. Through the integrated processing and feedback, the ALC offers QR24-specific drive processing.

The Signal Integrity Sensing pre-wiring ensures cable/connector compensation between the QR24 and ALC. This provides a 1:1, undistorted natural sound reproduction regardless of cable length and amplifier impedance load (down to 2 ohms).
