Quantec Yardstick 2493 - Analog/Stereo Room Simulator
2 analog input channels, 2 analog output channels, plug-in sample rate up to 192 kHz

The Quantec Yardstick 2493 room simulators are high-quality, digital sound processing devices based on the original 1982 QRS Room Simulation algorithm.

Due to its unobtrusive, natural character and its superb room simulation, the original QRS has become a lot more than just a well-know production tool for pop music. In the fields of classical music production, chamber music, as well as in movie post-production, the QRS is 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.

Due to the sophisticated characteristics of the QRS algorithm, any QUANTEC Room Simulator stands out favorably among the competition. But there are quite a few situations where its sonic qualities really shine:

In the final mix, where it is unobtrusively transparent with virtually no tendency to blur – even with a full dose over the entire set of tracks
In a multitude of productions in classical music, where any room impression with an artificial smack is undesirable – for stylistic reasons alone
In the production of movies and radio dramas, where its virtually tangible room illusions simulate real rooms, which – in cramped environments – may actually create a physically unpleasant feeling of pressure
In movie productions, using its outstanding ambience in spacious effects
In sound reinforcement and P.A., where those pronounced resonance lines and gaps in the acoustic spectrum of a hall not suited for musical performances can be averaged and smoothed out. As a result, the sound of a general-purpose municipal hall becomes more suitable for music, and the risk of feedback is reduced
During the musical-improvisatory play with the reverberation onset – or the effervescence of the room

Since the sound characteristic of the QRS algorithm – and thus that of Yardstick as well – is quite a bit different when compared to the competition, it inevitably will have a significant influence on the number and types of the available parameters.
