The PARC is a Parametric Adaptive Room Compensation system. Rives Audio designed the PARC because current stereo and home theater components have exceeded the capability of their environment. Today's hi end audio speakers and electronics have the capability of delivering a near flat response throughout the audible frequency range (20Hz to 20kHz). However, these systems interact with their environment, namely the room they are located in. One of the largest problems in typical listening rooms is standing waves or room modes (bass modes) caused by parallel walls. The PARC is specifically designed to alleviate this problem. To understand more about the issues of room modes, go to "the Listening Room".
The PARC is a 2 channel, 3 band (per channel) parametric equalizer (parametric eq) that can attenuate 3 separate frequencies at different ranges and amplitudes. It is purely analog based, so there is no digital conversion to corrupt the audio signal. The system uses components and modules developed for high end analog recording studios. Every item in the signal path is of the lowest noise and highest quality available. The engineers that developed the unit have literally dozens of years experience in designing low noise parametric equalizers (parametric eq) for the recording industry.
This is actuallu my second PARC. This time I bought it to try different system configuration, but in the end didn't need it.
Unit is in excellent condition, perfect functionally and has no cosmetic defects, that i can see. it is very transparent, and performs exactly as advertised, otherwise I wouldn't have re-purchased it.
