ANALOG OUTPUT SECTION:
The analog output section uses dual wide dynamic range 18 bit continuous bitstream auto calibration digital-to-
analog converters (made by Phillips) with 192 times oversampling. It has low total harmonic distortion devoid of
crossover distortion and incorporates digital de-emphasis. The DEQ 30 has both RCA and Balanced (Mini XLR™)
Outputs. The output voltage is 4 Volts rms for the RCA outputs and 8 Volts rms (4 Volts rms output per phase) for a
balanced system.
DIGITAL OUTPUTS:
Digital outputs use Professional Grade SPDIF transmitters. These are the same transmitters used in high-end
home audio and professional applications. The output frequency is 44.1 kHz. The DEQ 30 supports both TOSLINK
and COAX digital formats.
C-LOCK™ ANTI-JITTER REDUCTION CIRCUIT:
C-Lock™ Anti-Jitter clock recovery system virtually eliminates jitter from a digital signal. Jitter in a digital signal
creates amplitude errors in rapidly changing signals. The C-Lock™ circuitry strips away the existing clock
information and replaces it with a reconstituted correctly timed clock. The result is a perfectly timed digital signal.
POWER SUPPLY:
The power supply used in the DEQ 30 is a balanced high-frequency power supply. For optimal noise isolation,
power and signal grounds are isolated.
COMPUTER INTERFACE:
The DEQ 30 uses a RJ-11 port that supports a IBM computer compatible RS-232 data interface. Additionally,
there will be an optional remote interface that will be released in the future.
