Allen & Heath M-DX32-PRIME-IN-A: Studio-Grade 8-Channel Inputs for DX32

The Allen & Heath M-DX32-PRIME-IN-A is a DX32 PRIME input module that adds eight channels of premium XLR mic/line inputs to a DX32 modular expander. It uses 32-bit / 96 kHz conversion with multiple A/D devices running in parallel on each channel, plus a DC-coupled gain stage for exceptional low-frequency linearity. The result is an ultra-flat frequency response from 1 Hz to 40 kHz with a fast slew rate, delivering studio-grade capture at the stage box. As a plug-in module, it installs in the DX32 chassis alongside any mix of PRIME, analog, and digital modules. For engineers who want reference-quality inputs feeding a dLive, Avantis, SQ, or AHM system, it is the highest-fidelity front end in the range.

A DX32 Module, Not a Standalone Box

The DX32 is Allen & Heath's modular expander chassis, connecting to dLive, Avantis, SQ, or AHM systems over Cat5e using the SLink protocol. The M-DX32-PRIME-IN-A is one of the plug-in modules that populate that chassis; it is not a standalone stagebox and draws its power from the DX32 host. Each PRIME input module contributes eight XLR mic/line channels, and multiple modules can be combined and freely mixed with analog and digital DX32 modules. This modular design lets an integrator tailor the exact input and output count a venue needs, then change it later by swapping modules. It is the reason a single DX32 can serve as a flexible, high-quality I/O node for very different systems.

Why the Converters and DC-Coupled Gain Stage Matter

Running multiple A/D converters in parallel on each channel lowers the effective noise floor and distortion beyond what a single converter achieves, which is why the PRIME module is positioned as a critical-listening front end. The DC-coupled gain stage removes the coupling capacitors that, in AC-coupled designs, introduce subtle low-frequency phase shift and distortion, so bass reproduction stays tight and accurate. A fast slew rate and a response extending flat from 1 Hz to 40 kHz mean transients and harmonics pass through cleanly. In practice, this preserves the depth and detail of a source before the console ever touches it. For broadcast, orchestral, and audiophile-grade capture, that front-end quality is the whole point.

Who the M-DX32-PRIME-IN-A Is For

This module is for engineers building DX32 stageboxes for dLive, Avantis, SQ, or AHM who want the cleanest possible inputs for critical capture. It suits broadcast, classical, and high-end install work where the front end must not compromise the source. Because DX32 modules mix freely, a system can combine PRIME inputs where fidelity matters most with standard analog inputs elsewhere to manage cost and count. The module is powered by the DX32 host and requires a DX32 chassis to operate. When only reference-grade inputs will do, the M-DX32-PRIME-IN-A is the choice.
