The Netherlands - Alcons has introduced the QRP20, a two-way column array system with high-Q directivity for increased projection control to be used as vertical sound system, for both permanent and portable applications.
It is specifically designed for applications where ultimate fidelity response needs to be projected with wide horizontal and narrow vertical coverage, ideal in acoustically challenging environments, or applications where intelligibility-over-distance is required.
Loaded with the RBN401 4” pro-ribbon driver on a ‘Morpher’ lens, the system offers a very high throw-efficiency and projection control, due to the pro-ribbon’s all-natural cylindrical wavefront.
The QRP’s are powered and controlled by the ALC amplified loudspeaker controller; Through the integrated VHIR processing, audiophile amplifier stages and Signal Integrity Sensing feedback circuit, the ALC offers QRP20-specific drive processing, delivering absolute maximum sound quality with increased headroom and utmost operation reliability and flexibility.
Philip de Haan, head of Alcons Audio R&D: “The essence of the Q-series is the isophasic wavefront of our pro-ribbon mid/high frequency transducer technology, delivering the razor-sharp, side-lobe free projection control in the vertical plane and throw, the Q-series is known for.”
Philip concludes: “We’ve seen in many, typically acoustically challenging applications, that the necessity for controlling the sound projection in order to get a satisfactory intelligibility lead to severe sacrifices on sound quality and dynamic output with existing solutions, either passive or steered. The QRP20 is proof that an exceptional, SPL independent intelligibility and throw is possible without any sacrifice on sound quality and performance, regardless of system size.”
The QRP20 is available in two versions with 90-degree (QRP20/90) and 120-degree (QRP20/120) horizontal dispersion.
