In these specifications, when dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms.
All input AD converters (INPUT 1–16, OMNI INPUT 1–4, TALKBACK) are 24-bit linear, 128-times oversampling. (@fs=44.1,
48 kHz)
+48 V DC (phantom power) is supplied to CH INPUT (1–16) XLR type connectors via individual switches.
In these specifications, when dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms.
All output DA converters (OMINI OUT 1–12, PHONES) are 24-bit, 128-times oversampling. (@fs=44.1, 48 kHz)
