Multi-Unit Phase Response
Multiple DAC1 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.
