The DEQX Calibrated™ PDC-2.6 HD 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.The processor only is intended to be used where a preamplifier or HT receiver/processor is already
in use and DEQX is only required for speaker and/or room correction functions. When using any of
the unit’s active crossover features, the unit would be connected directly in front of power amplifiers,
being driven by the output of a preamplifier.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 timing (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 used together for multi-channel configurations such as 4.2 and 5.1 to
7.7 configurations.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-2.6 processor contains
improved power supplies and analogue electronics to preserve the system’s digital processing
transparency as much as possible.
