Multi-Unit Phase Response
Any combination of DAC1, DAC1 USB, and DAC1 PRE converters may be used to create a multi-
channel playback system that maintains phase accuracy across all channels at sample rates up to
110 kHz. The above graph shows the differential phase between 10 audio channels using 5 DAC1
converters operating at 96 kHz. The DAC1 converters were chosen from stock at random, and
measurements were made using a random combination of Coaxial, XLR, and Optical inputs. The
type of digital interface used has no measurable effect on the phase. Please note that no reference
or synchronization cables are required to create a phase accurate multi-channel playback system
using DAC1 converters at sample rates up to 110 kHz.
