PARC - Parametric Adaptive Room Compensation. It's designed to deal with bass modes. In some rooms, and particularly the hotel rooms at the Westin with solid plaster walls the room dimensions are not optimal and it can reinforce certain bass frequencies causing the bass to sound boomy and the midrange unclear. This is not the fault of the equipment, but the interaction with the room. One room at HE 2003 had 10 x 20 x 30 dimensions. It doesn't take much to figure out this will be a big problem. It had a 16 db bump at 114 Hz--almost unlistenable without the PARC. Great equipment in that room--but the room was the problem--not the equipment.
There is a forthcoming review of the PARC in the July issue of Stereophile. Until then, you can get more information on the PARC on our website.
