Preamp & DAC |

Preamp features |
Underneath the hood of the PDC-2.6P are several features
that make it ideal as a Preamp.
Remote control of
Input source switching (1x SPDIF, 1x AES/EBU, 1x Balanced Analog,
1x RCA Analog)
Volume control, implemented post-DAC on the analog signal to maintain
full bit-resolution in the digital domain
3-Band fully parametric digital tone control providing Media Correction
with 100 profile memory

The DEQX Calibrated™ Hardware Technology |
DEQX's expertise in analog and digital
hardware design has produced an excellent hardware implementation of
a Preamp, DAC, ADC and DSP engine. All circuit sections are carefully
laid out to minimize interference between one another, and to maximize
performance. The power supply design used in DEQX products features
three levels of voltage regulation to achieve a clean supply of power
for each voltage rail.
In their most basic operation, the DEQX PDC 2.6 and 2.6P operate
as a high fidelity digital to analog converter.

From using quality components, through good design
and careful PCB layout, an exceptionally well performing DAC has been
realized.
Even with no other features of the PDC processing
in operation, the PDC 2.6 and 2.6P DAC stages are comparable to standalone
DAC units of similar and even greater price.
The DAC sections are based around an Analog Devices 24-bit, 192kHz
capable differential multibit sigma-delta converter chip, which operates
at an internal sampling rate of 6MHz.
The measured in-system performance of the DAC and its associated
output stage is exceptional. A measured dynamic range of -108.9dB-A,
and THD of 0.00013% (1kHz, -6dBFS) |
