The most basic
implementation of the PDC-2.6P (preamp) is very easy to use and does
not require any PC set-up, or require the DEQX Calibration/measurement
kit. The 2-ch (stereo) PDC-2.6P provides 4-input Preamp, DAC and volume
control, with 3-band parametric EQ. All control is by the remote control.
The remote sets volume, selects inputs and also controls the 3-band
parametric room and media correction EQ. A resistor-stepped attenuator
maintains full DAC resolution at low listening levels and the minimum-phase
EQ does not compromise sound quality.
The EQ has 100-memories to store
and recall the correction settings. The three bands are; a bass shelf
filter with variable frequency and Q, a full mid parametric band
(20Hz to 20 KHz) with bandwidth (Q) variable from one semitone to four
octaves wide, and a high shelf filter also with variable frequency
and Q.
The Lo, Mid and Hi settings default to simple tone controls,
but precision EQ can be applied by first selecting the approximate
frequency in octaves (0-9) And then the < and > buttons move
in semitone increments - the up/down buttons adjusts level in 1dB
steps. A 0dB button resets the band being set to ‘no-EQ’,
and an ‘EQ reset’ button
ensures all 3-bands are set to zero. For simple tone control, a Lo,
Mid or Hi buttons is selected then the up/down button provides quick
gain or cut for each of the three bands.
The PDC-2.6P processor can
be connected between an existing stereo or Home Theatre pre-amp
and power amp for equalization, or it can be the sole pre-amp. The
remote control selects from four inputs; two digital (XLR balanced
and RCA unbalanced) and two analogue (XLR balanced and RCA unbalanced).
One PDC-2.6P unit processes 2-input channels in analogue or digital
(PCM) to 96KHz - compressed or surround digital formats are ignored.
Multiple PDC-2.6P units can be used to provide surround formats when
driven by a surround decoder’s analogue outputs. However,
a single PDC-2.6P can be used to correct only the main left/right
speakers of a surround system, ensuring that Stereo CD and film
music sound their best (also
see BASIC+RC plus Sub config).
