Designed by noted acoustician Bob Alach, the main studio provides 14 x 10 feet of usable recording space on a reflective soft-pine floor, and features RPG maple QRD diffusers, fiberglass/masonite bass traps, symmetric construction, and other design features to provide a pristine, transparent environment, with near-flat, phase-correct response at the listening position.  The acoustical suspended ceiling allows low-frequency sounds to take advantage of the full volume provided by the sloping, 14-foot-high roof, while high-frequency sounds are absorbed or diffused by additional RPG Omniffusor panels.  Monitoring is through a pair of SLS S8R mains, fed by the HUI's custom-modified analog preamp section through a Bryston 4B amplifier and then through a custom-modified Klark-Teknik DN-410 parametric.
