Allen & Heath dLive DM64 MixRack

The dLive DM64 is the largest S Class MixRack: 64 mic/line inputs, 32 line outputs and the 128-input / 64-bus XCVI processing engine in a 10U chassis. It is used on major touring rigs that need high stage-I/O density and redundant surface links. It pairs naturally with S5000 or S7000 surfaces and can also run without a surface under network control.

01 · What it does—and what that changes in your rig.

Product overview

Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.

The payoff

Digital Mixer decisions, organized around the whole rig.

The dLive DM64 is Allen & Heath's largest MixRack in the dLive line — a dedicated stage box and processing engine that lives in your rack while a surface controls it remotely over gigaACE. There is no fader or screen on the unit itself; it is purely infrastructure. Its job is to convert 128 mic preamps and route up to 64 analog outputs while the XCVI processing engine handles all the DSP. On a major touring rig where the monitor world and FOH world are splitting a common stage snake, or where an IEM rig needs every input available independently, this is the piece that makes that possible without a compromise on channel count.

Function

How it works in the path

Eleven rack units and 31.5 kg means this is not a fly-date decision — it's a commitment to a specific case and a specific truck position. The 472 mm depth demands a proper touring rack, not a shallow ATA shell. Power draw sits at 200 W nominal with a 280 W max, and critically, there are two IEC inlets for redundant power feeds — run each to a separate circuit or UPS leg. The dual gigaACE ports (A and B on both the surface link and the stage expansion) mean you carry a redundant Cat6 run as standard practice, not an afterthought. Two M-Series option slots let you add Dante, MADI, or other I/O cards to bridge into a house system or a broadcast split without touching your analog patch.

Best fit

Where it earns its place in the rack

If you are running 48 or fewer inputs and a single monitor engineer, the DM64 is more rack than you need — the DM48 covers that territory in 6U and saves meaningful weight. The DM64 earns its place when the input list pushes past 64, when you need the full 64 analog outputs for a large IEM and wedge hybrid rig, or when a second engineer is sharing the MixRack over a second gigaACE surface link. Engineers already in the dLive ecosystem will find the show-file and preamp-recall workflow familiar. If your organization runs DiGiCo or Avid infrastructure everywhere else, the DM64 does not bridge into those ecosystems natively — the option slots can help, but plan that integration before the advance, not at load-in.

In the rack

Details worth deciding before load-in.

  • Run the two IEC power feeds from physically separate circuits — if your venue or generator has a second leg available, use it. A single breaker trip should never kill the MixRack mid-show.
  • Patch the gigaACE A and B surface links on different physical cable paths through the stage, not bundled in the same trunk — redundancy only matters if the failure mode that kills one cable can't kill both simultaneously.
  • Label the M-Series option slots in your show file and on the physical rack with their card type and signal format before the tour starts; swapping cards mid-tour to troubleshoot is a last resort, not a workflow.
  • Budget the full 472 mm depth plus cable clearance at the rear — in a standard 500 mm deep ATA rack there is virtually no room for XLR breakout tails. Either use a deeper case or plan to dress outputs to a patch bay in an adjacent rack unit.
