Analog Inputs Specs
1. Sensitivity is the lowest level that will produce an output of +4 dB (1.23 V) or the nominal output level when
the 03D is set to maximum gain (all faders and level controls at maximum positions).
2. Input channel XLR-type connectors are balanced (pin 1 = ground, pin 2 = hot, pin 3 = cold).
3. Input channel and ST input TRS phone jacks are balanced (tip = hot, ring = cold, sleeve = ground).
4. Input channel insert connections are unbalanced (tip = send, ring = return, sleeve = ground).
5. When dB represents a specific voltage, 0 dB is referenced to 0.775 V rms.
6. For 2TR IN levels, 0 dBV is referenced to 1.00 V rms.
7. Input channels 1–16 and ST IN use linear 20-bit 64-times oversampling A/D converters.
8. Individually switched +48 V phantom power is available on input channels 1–8.
