Quantec 2492 Yardstick Digital Reverb

The Quantec 2492 Yardstick room simulators are high-quality, digital sound processing devices based on the original 1982 QRS Room Simulation algorithm. The Quantec 2492 Yardstick is a stereo device equipped with2 digital AES3 input channels and 2 digital AES3 output channels.


Unlike a reverberator with its raytracing perspective (reflections), a QUANTEC Room Simulator approaches room acoustics from the air as a carrier medium (resonances). Translated to a wind instrument, the competition concentrates on the wooden or brass instrument body, while we turn our attention to the vibrating air column within the instrument.

Due to its unobtrusive, natural character and its superb room simulation, the QUANTEC Room Simulators have become a lot more than just well-know production tools for pop music.

In the fields of classical music production, chamber music, as well as in movie post-production, the QUANTEC Room Simulators are considered to be the Yardstick for all competing products.

In other words, whenever a natural sounding ambience is desired, and any kind of artificial reverberation is not, the QRS algorithm has been repeatedly praised by countless sound professionals.
