The DEQX Calibrated™ PDC-2.6P HD Preamp/Processor is a stereo digital processor offering
DEQX’s patented speaker and room correction technology. When connected to a PC running
DEQX’s software, the PDC allows you to measure and correct your main speakers and subwoofers
using its largely automated Wizard driven measurement, analysis, and correction software.Our loudspeaker’s introduce between ten to one hundred times more distortion, as well as errors
in the form of inaccurate frequency-response and incoherent timing, than the signal that arrives to
drive them. Unlike DSP room correction systems, whose measurements must contain room acoustic
effects, the PDC first measures and corrects a speaker’s native (anechoic) behavior so that timin
(phase and group-delay) errors and frequency-response errors can be compensated in detail
before measuring and correcting room acoustics.The PDC can be used for correcting passive speakers, or if you have additional amplifiers available
and are able to bypass your existing passive crossovers, its six analogue outputs provide up to 3-way
active crossovers. Configurations supported are; passive speakers plus the option of one or two
subwoofers, 2-way active speakers plus optional subwoofers, and 3-way active speakers.Stereo digital and analogue Inputs include: SPDIF (RCA), AES/EBU (XLR), unbalanced analog
(RCA), balanced analogue (XLR). Standard outputs are analogue unbalanced (RCA). Optional
outputs include balanced analogue (6 x XLR) OR Digital outputs (3 x XLR, 3 x RCA).  Multiple
PDC-2,6 units can connected together for multi-channel configurations such as 4.2 and 5.1 to
7.7 configurations.The Preamp features of the PDC-2.6P HD include six digitally controlled analogue volume controls
that allow the DACs to operate at their maximum resolution at low listening levels. The remote control
provides volume control, input selection, four different speaker and room correction profile selections,
and lo, mid and hi, tone controls where the mid control provides a fully parametric EQ band. 100 tone
control settings can be set, saved and recalled using the remote control (without a PC being connected).The industry leading SHARC 32-bit floating point DSPs from Analogue devices contribute only
about 0.00001% distortion and noise. This new HD version of the PDC-2.6P contains improved
power supplies and analogue electronics to preserve the system’s digital processing transparency
as much as possible.
