In these specifications, when dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms.
For 2TR IN ANALOG 1, 2 levels, 0 dBV is referenced to 1.00 Vrms.
All input AD converters (except INSERT IN 1–24) are 24-bit linear, 128-times oversampling.
+48 V DC (phantom power) is supplied to CH INPUT (1–24) XLR type connectors via individual switches.
STEREO OUT [L, R], 0 dBV is referenced to 1.00 Vrms.
In these specifications, when dB represents a specific voltage, 0 dB is referenced to 0.775 Vrms.
All output DA converters (except INSERT OUT 1–24) are 24-bit, 128-times oversampling.
