-
Sample Rate Converter (SRC) THD+N -120dB @ 0dBFS, 1kHz; Latency <0.3ms
Outputs
-
8 channels (4 two-channel outputs)
-
Input sample rate converters (SRCs)
-
Electrical isolation between inputs, outputs, and device (if configured for differential mode, 110Ohm)
-
AES3 channel status management, non-audio detection
-
Master-sync capable
