Conference and stage modes MH-03

• Functional reference design: six individual conference microphone feeds, echo reference, separate USB call send and return, room sound, four monitor mixes and recording.

RF

6 wireless speech channels

SB

1 stagebox 16 analogue inputs used

WIRED

8 wired microphone / DI channels stage mode only

EX

1 HDMI interface same device as video drawing

MIX

1 console: at least 32 inputs 24 processing channels used ST stereo + 8 mono-equivalent AUX

AEC

1 AEC DSP: 6 speech AEC Dante licence at least 16x16 RX 10 / TX 8 used reference L/R summed to mono

UC

1 conference PC same device as video drawing

PA

1 room DSP 2 in / 4 out used

SP

2 powered main groups cabinet count by coverage design

FILL

2 powered front fills

MON

4 powered monitors muted in conference baseline

REC

1 recorder/encoder same device as video drawing

1. RF → SB6 analogue
2. WIRED → SB8 analogue
3. EX → SBstereo line: 2 analogue
4. SB → MIX16 Dante via AV switch
5. MIX → AECDante 1-6: individual raw speech
6. MIX → AECDante 7-8: direct content L/R
7. MIX → AECDante 9-10: reference AUX7-8 post-fader remote + content only same dual-mono PA content
8. AEC → UCUSB send: AEC speech + content remote excluded
9. UC → AECUSB receive: remote L/R
10. AEC → MIXDante TX1-2: remote L/R
11. AEC → MIXDante TX3-8: AEC-clean speech6 record-only returns
12. MIX → PAST L/R: 2 line outputs
13. PA → SPline 1-2
14. PA → FILLline 3-4
15. MIX → MONAUX1-4: 4 mono line outputs
16. MIX → RECAUX5-6: stereo line conference: clean speech + content + remote stage: raw sources + content

Reference design; 48 kHz audio. Stage mode disconnects call; conference mutes stage inputs. AEC-clean returns never feed PA or AEC microphone inputs. Raw speech never joins clean speech in conference recording. Six microphone inputs use individual pre-processing direct outs.

• Functional reference design: local programme feeds the call; remote video goes separately to displays and the recorder, avoiding a video return loop.
