Shure P300 Control Spec

Summary

Shure P300 IntelliMix audio processor with Ethernet (TCP/IP) control on port 2202. ASCII command protocol using < GET|SET xx PARAM > / < REP xx PARAM > framing. Supports Dante and analog I/O, automixing, AEC, AGC, compressor, PEQ, matrix mixing, and metering. 28 audio channels across inputs, outputs, and processing blocks.

# UNRESOLVED: power-on sequencing requirements not stated in source

Notes

• All commands and responses are ASCII, framed with < and >.
• Channel numbers (xx) are two-digit ASCII: 00-28. See channel assignment table in source.
• Most parameters send unsolicited < REP ... > on change — polling not required after initial < GET xx ALL > on power-up.
• Gain values use shifted/scaled integer encoding (documented per command). All in 0.1 dB resolution.
• Metering sample data: 000-060 = -60 to 0 dBFS.
• Meter rates: values 00001-00099 ms are invalid and return < REP ERR >.
• Flash auto-disables after 30 seconds.
• Preset numbers: SET accepts 1-10 (leading zero optional); REP always returns 01-10.
• Some commands require firmware 4.1.x or newer (Dante outputs 3-8 channels 23-28, DIRECTOUT_POINT, GATE_INHIBIT deprecated).
• Static IP configuration requires Shure Designer software; control IP used for TCP/IP communication.
