Summary

The Shure ANIUSB-MATRIX is an audio network interface / matrix mixer for Dante, analog, and USB audio routing, controlled via Ethernet (TCP/IP) using ASCII command strings. This spec covers the command-string protocol: GET/SET/REP/SAMPLE message types, channel-scoped audio gain/mute, matrix mixer routing/gain, presets, PEQ, metering, and call-status features.

Transport

protocols:
  - tcp
addressing:
  port: 2202
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable    # not present - device has no power on/off command (reboot only)
# - routable     # inferred: matrix mixer routing + audio route presets present
- routable      # inferred from MATRIX_MXR_ROUTE / PRESET_AUDIO_ROUTE commands
- queryable     # inferred from GET command examples
- levelable     # inferred from AUDIO_GAIN_HI_RES / MATRIX_MXR_GAIN commands

Actions

# Channel map (xx in commands): 00=All, 01-04=Dante Inputs, 05=Analog Input,
# 06=USB Input, 07-08=Dante Outputs, 09=Analog Output, 10=USB Output.
# All payloads ASCII, verbatim angle-bracket syntax from source.

Macros

# UNRESOLVED: no multi-step sequences described explicitly in source

# caution stated in source.

Notes

  • Control system is AMX, Crestron, or Extron; select "Client" mode in the AMX/Crestron program.
  • All messages and level/gain indicators are ASCII (not binary).
  • Channel numbering: 00 = all channels, 01-04 = Dante Inputs, 05 = Analog Input, 06 = USB Input, 07-08 = Dante Outputs, 09 = Analog Output, 10 = USB Output.
  • Two firmware families in field: V1 uses < GET xx ALL > (channel required), V3 uses < GET ALL >.
  • METER_RATE values 00001-00099 are invalid and return < REP ERR >.
  • SET PRESET with leading zero is optional; GET/REP PRESET always uses 01-10 (0 = none active).
  • Flash auto-disables after 30 seconds.
  • Limiters only on output channels 07-10; PEQ only on blocks 07 and 10.
