Instruction Manual Revision D Page 27
Multi-Unit Phase Response
Any combination of DAC1 and DAC1 USB 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.
