Allen & Heath AH-MPS-16 Optional redundant hot swappable PSU

Product Overview

The Allen & Heath AH-MPS-16 is a touring-grade optional redundant power supply unit engineered for dLive S Class mixing surfaces, dLive MixRacks, and the DX32 Modular Expander. Designed for mission-critical live sound and commercial AV installations where a single point of power failure is not acceptable, the MPS-16 enables a fully redundant dual-PSU configuration with live hot-swap capability — meaning a failed power supply can be replaced without interrupting the audio system. Weighing only 1.27kg, the MPS-16 is light enough to deploy as a dual-redundant pair within the DM MixRack of a compact dLive Wings system without significantly increasing system weight. Its fanless design ensures completely silent operation, making it equally suited to theatre, broadcast, and studio environments where ambient noise is a concern.

Product Description

Power supply redundancy is a standard requirement for any professional audio installation or touring production where system downtime during a live event is not an option. The MPS-16 addresses this requirement for the dLive platform with a well-engineered, purpose-built solution that fits the existing chassis of dLive S Class surfaces, MixRacks, and the DX32 expander.

Two MPS-16 units installed in the same chassis operate in a load-sharing configuration. If one supply fails, the remaining unit immediately carries the full load without any interruption to the audio output. The hot-swap capability means the failed unit can be removed and replaced while the system remains live and fully operational — a critical capability for live events with no technical break in the schedule.

The fanless thermal design eliminates the noise contribution that a conventional PSU fan would add to the system's noise floor. This makes the MPS-16 particularly appropriate for theatre productions, broadcast studios, and installed sound environments where the ambient noise level is measured and controlled. For compact dLive systems using the DM MixRack in a Wings configuration, two MPS-16 units add only 2.54kg to the total system weight — a meaningful consideration for touring engineers managing total case weight.

The MPS-16 operates on universal mains input (100–240V AC, 50/60Hz), making it appropriate for international touring without modification. It is sold individually; two units are required for a redundant configuration.

Key Features

• Hot-Swappable Redundancy — Failed PSU can be removed and replaced while the system remains live with no audio interruption
• Dual-Redundant Configuration — Two MPS-16 units in the same chassis provide full load redundancy for mission-critical deployments
• Fanless Silent Operation — Completely noise-free design for theatre, broadcast, and studio environments
• Lightweight at 1.27kg — Suitable for dual-PSU deployment in compact dLive Wings systems without significant weight penalty
• Universal Mains Input — 100–240V AC, 50/60Hz operation for international compatibility
• Compatible with dLive S Class, MixRacks, and DX32 — Covers the primary dLive touring and installed hardware platforms

Typical Applications

• Touring and festival dLive systems where PSU failure during a live show is not acceptable
• Broadcast and television production using dLive where continuous audio output is mandatory
• Theatre installations where system reliability and silent operation are both required
• Permanent commercial AV installations with dLive as the primary mixing or distribution platform
• Mission-critical live event productions with no scheduled break for technical recovery
• International touring requiring universal mains compatibility across multiple regions

Frequently Asked Questions

Do I need to purchase two MPS-16 units for redundancy?

Yes. The MPS-16 is sold as a single unit. Two units must be installed in the same dLive chassis to achieve the hot-swap redundant configuration.

Which Allen & Heath products is the MPS-16 compatible with?

The MPS-16 is compatible with dLive S Class mixing surfaces, all dLive MixRack models, and the DX32 Modular Expander.

Can the MPS-16 be hot-swapped during a live performance?

Yes. The hot-swap design allows a failed MPS-16 to be removed and replaced while the remaining unit carries the full system load, with no interruption to audio output.

Is the MPS-16 suitable for theatre and studio environments?

Yes. The fanless design produces no mechanical noise, making it appropriate for any environment where system noise floor is a concern, including theatre, broadcast studios, and recording facilities.

Does the MPS-16 add significant weight to a touring dLive system?

No. At 1.27kg per unit, a dual-redundant pair adds only 2.54kg total. This is manageable even in compact dLive Wings systems using the DM MixRack.

Is the MPS-16 compatible with international mains voltages?

Yes. The universal 100–240V AC, 50/60Hz input makes the MPS-16 compatible with mains supply standards in all major touring regions without any adaptation.
