Alcons Audio has released high-resolution measurement and simulation data for its L-series pro-ribbon line arrays and Q-series pro-ribbon column arrays. The data is supplied in GLL (Generic Loudspeaker Library) format for use with the Ease 4.3 acoustic prediction program and newly released ARC2 (Alcons Ribbon Calculator) array set-up tool, which is based on the Ease Focus 2 program.

The simulation includes reverb times, speech intelligibility and other parameters, and can be viewed in horizontal and vertical planes. Multiple arrays are possible.

The GLL data are based on very high-resolution, actual system measurements: The QR systems are measured with 1° accuracy, the LR systems with 2° accuracy and the other systems with the standard 5° accuracy.

‘We have included all of our system configurations and processing optimisations from the DDP digital drive processor and the new Sentinel amplified loudspeaker controllers,’ says Alcons Audio’s Tom Back. ‘These, in combination with the very low manufacturing tolerance of ±1dB, allows GLL-based simulations to convert Alcons’ sound systems into true precision instruments and is another step towards our goal to deliver the most accurate sound reproduction possible.’

Supported systems:
· LR7 and LR7/90 micro line-arrays
· LR14 and LR14/90 ultra-compact line-arrays
· LR16 compact line-array
· QR18 line-source column
· QR36 line-source column

All systems include their accompanying bass cabinets, along with the QR18 and QR36 line-source columns, their QM low and mid array extensions, smaller systems of the T-series and the S-series general sound reinforcement systems. New systems will be added regularly into the library base.
