In these specifications, when dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms.
For 2TR IN levels, 0 dBV is referenced to 1.00 Vrms.
All input AD converters (CH INPUT 1–16) are 24-bit linear, 128-times oversampling. (@fs=44.1, 48 kHz)
+48 V DC (phantom power) is supplied to CH INPUT (1–12) XLR type connectors via individual switches.
Three P48V switches CH1–4, 5–8, 9–12 turn on the phantom power for inputs 1–4, 5–8, 9–12 respectively.
In these specifications, when dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms.
2TR OUT [L, R] levels, 0 dBV is referenced to 1.00 Vrms.
All output DA converters are 24-bit, 128-times oversampling. (@fs=44.1, 48 kHz)
