VRAS (original) (raw)

The Variable Room Acoustics System is an acoustic enhancement system for controlling room acoustics electronically. Such systems are increasingly being used to provide variable acoustics for multipurpose venues. In addition, VRAS uses a number of microphones close to the stage area to detect early energy from the performers, which is used to generate early reflections. Such systems are termed in-line or non-regenerative. In-line systems aim to minimise the effects of regeneration by detecting stage sound at a high level, and may then be used to generate early reflections or late reverberation.
