Manufacturer's Description from Other
From 1982 comes a novel digital effects processor. From the manual:
The QUANTEC Room-Simulator - a computer technology-based system for the generation of acoustical effects simulating variable-sized rooms. A new technical concept enables emulating the acoustical behavior common to spaces of any volume or size, so that acoustical impressions ranging from a tin can to a columned cathedral may be synthesized and created at fingertip command. Contrary to standard reverberators, the QRS enables the reproduction of the selected space's inherent resonances, which are a function of its basic enclosed volume, in that their density and distribution are precisely established. In conjunction with the legendary "first reflection" this is the effect which enables the ear to establish spatial volume and size of a percepted room. Besides this, the QRS has two additional built-in programmes: "FREEZE-Effect" and "ENHANCE-Effect."
The QRS stores up to 64 reverb programs, each with 8 parameters that can be finely tuned. It has a FREEZE mode that creates a physically impossible space in which sound is trapped, pinging between surfaces. It also has an ENHANCE mode consisting of a number of reflections of equal strength, on which there is superimposed a decreasing sequence of denser, but quite perceptibly discrete reflections.
It has four balanced outputs. In standard configuration the reverb and reflections are mixed on the first two outputs and the 3rd and 4th output are rear channels useful for quadrophonic applications. In the optional configuration the first two outputs carry the reflections and the third and fourth outputs carry the reverb signal.
Included with this unit is a fully functional RF remote and the original owners manual.
