Post-Fader Monitor Output Level Offsets
- each surround and stereo channel independently adjustable in 0.5-dB steps over a ±12-dB range
Bass Management
- Supported Sample Rates: 44.1, 48, 88.2, and 96 kHz only
- Crossover Frequency and Type: ・ dB @ 40, 50, 60, or 80 Hz, symmetrical for low-pass and high-pass filters, maximally flat i
- Filter Slope: 12 or 24 dB/octave
- Overall Operation: independent on/off selectable for surround and stereo post-fader monitor outputs
Downmix
- Functions: surround to stereo, stereo to mono
- Surround to Stereo:
- L @ 0 or ・ dB; i
- R @ 0 or ・ dB; i
- C @ ・ or ・ dB summed with L and R; /l
- LFE @ full attenuation or ・ dB summed with L and R; i
- LS @ ・ or ・ dB summed with L; /l
- RS @ ・ or ・ dB summed with R; /l
- C, SUB, LS, and RS monitor outputs mute
- Stereo to Mono:
- L @ ・ dB summed with R @ ・ dB to C; /l
- L, R, LS, RS, and SUB monitor outputs mute
- For a surround input this results in the C output being the sum of L @ ・ or ・ dB, R @ ・ or ・ dB; C @ ・ or ・ dB, LFE @ full attenuation or ・ dB; LS @ ・ or ・ dB, and RS @ ・ or ・ dB @ 窶・ or
