Stage by stage

Wireless mics (×2)

Dante Input ch 1 / 2 (Wireless-1, Wireless-2)→AEC, 4-channel block→4 Uber Filter presets→Mic-type Source Selector→Advanced Compressor→Feedback Suppressor, 16 band→Gain Sharing Auto Mixer 2×1

Each mic feeds all four EQ presets at once: HH - 7, Lav - 7, Boundary - 7, Goose - 7. The Source Selector (WLX1Type, WLX2Type) passes one of them, chosen by logic from the Shure ULXD4D's TX_TYPE report. A Peak Meter taps both mics straight off Dante.

Mixing and levels

Auto Mixer out 1→Level "Wireless 1"Auto Mixer out 2→Level "Wireless 2"Auto Mixer mix→Level "Mic Mix"USB X Input→Level "USB Rx"

These four Level blocks are what the TEC-X Volume Up, Volume Down and Mute buttons drive, through the ramp Logic States Wlx1Ramp, Wlx2Ramp, MicRamp and USBRamp.

Matrix Mixer 5×2

in 1 DIAGin 2 Mic 1in 3 Mic 2in 4 Mixin 5 USB Rx→out 1 AMP (labelled Spkr)out 2 USB Tx

The DIAG input comes from a Diagnostics custom block: a 3-input Source Selector choosing Aux In, a Tone Generator or a Noise Generator. Crosspoint levels and on/off states are runtime settings that couldn't be read reliably from the file, so check them in the Matrix Mixer dialog.

Room output

Uber Filter, 12 filter→RMS Limiter→AEC Ref→Output, 2 channel (AMP)

The AEC Ref after the limiter is the far-end reference for the AEC block, so it hears exactly what the room speakers play. An RMS Meter watches this output.

USB to the room PC

AI Noise Reduction→USB X Output (USB Tx)

An RMS Meter watches this send too.

Instance tags are the names to use for TTP and for TEC-X actions. Blocks without a custom tag keep Tesira's default name, such as Aec1 or Mixer2.
