Low-Noise Internal Power
Supply
The internal power supply supports all
international voltages with generous margins
for over and under voltage conditions. It has
excellent immunity to noise on the AC line
and no external AC filtering is required.
Phase-Accurate Multi-Track and
5.1
The DAC1 HDR is phase-accurate between
channels at all sample rates, and is phase
accurate between any combination of DAC1,
DAC1 USB, DAC1 PRE, and DAC1 HDR
converters at sample rates up to 96 kHz.
Phase-accurate multi-track and 5.1 surround
systems are easily constructed using any
combination of DAC1 series converters.
Automatic Digital De-Emphasis
Pre-emphasis was used on many early CD
recordings. It is rarely used on newer
recordings and consequently some D/A
converters omit de-emphasis. The DAC1
HDR will correctly apply precise digital de-
emphasis when and if it is needed. The de-
emphasis circuit supports 44.1, 48, 88.2 and
96-kHz sample rates and is automatically
enabled in response to the pre-emphasis
status bits in consumer format digital signals.
