Shure IntelliMix P300-IMX Audio Conferencing Processor

Product Overview

The Shure IntelliMix P300 audio conferencing processor is a dedicated DSP that delivers clean, echo-free room audio for conference rooms, boardrooms, and unified communications deployments. The P300-IMX provides eight channels of microphone processing with acoustic echo cancellation, noise reduction, and automatic gain control, plus IntelliMix automatic mixing and matrix mixing. With 10 Dante inputs, two analog inputs, USB, and a mobile connection, this conference room DSP ties Shure networked microphones, codecs, and PC-based video applications into one signal chain. Predefined presets reduce commissioning time for AV integrators.

Product Description

The Shure P300-IMX is purpose-built to simplify conference room audio for AV system designers and integrators. It offers eight channels of microphone processing, each with acoustic echo cancellation, noise reduction, and automatic gain control, alongside IntelliMix automatic mixing, matrix mixing, delay, a compressor, and parametric EQ. Connectivity is built for real deployments: 10 Dante audio input channels and two Dante output channels over RJ45, two analog inputs and two analog outputs on 3-pin block connectors, a USB 2.0 Type B port that carries two summed-mono input and output channels for PC-based videoconferencing, and a TRRS 3.5 mm mobile jack. This range of I/O lets the P300 connect Shure networked array microphones, a hardware codec, a soft codec on a PC, and a mobile device into one AV conferencing system. A predefined matrix and presets reduce the lengthy commissioning time often associated with DSP, helping integrators standardize rooms quickly. Powered by PoE Plus, the unit installs cleanly in a rack or above-ceiling location with a single network cable for audio and power. As a Dante conferencing processor, the P300 is a core building block for repeatable, scalable meeting-room designs.

Frequently Asked Questions

What does the P300 connect in a conference room?
It connects 10 Dante inputs, two analog inputs, USB, and a mobile device to an AV conferencing system or PC-based videoconferencing application.

Does the P300 work with soft codecs like Zoom or Teams?
Yes. The USB 2.0 Type B port carries summed-mono input and output channels for PC-based videoconferencing platforms.

How much processing does each microphone channel get?
Each of the eight microphone channels includes acoustic echo cancellation, noise reduction, and automatic gain control, with IntelliMix automatic mixing across the system.

How is the P300 powered and installed?
The processor is powered by IEEE 802.3at PoE Plus, so a single network cable provides both power and Dante audio for a clean rack or above-ceiling install.

Does the P300 speed up room commissioning?
Yes. A predefined matrix and presets reduce the commissioning time typically associated with DSP, helping integrators standardize repeatable room designs.

Which microphones pair with the P300?
It is commonly paired with Shure Microflex Advance array microphones such as the MXA310 and MXA710 over Dante.
