Meridian 251 Powered Zone Controller

The Meridian 251 is a compact 1U zone controller with two onboard amplifier channels — the step up from the 218 for rooms where a separate power amplifier is not practical. It combines digital and analogue inputs, high-resolution MQA decoding, Roon Ready compatibility, and Sooloos music platform integration with enough amplification to drive a pair of speakers or a soundbar directly. All in a half-width 1U unit that fits in a rack, on a shelf, or in a plant room.

In a multi-room Meridian system, the 251 covers zones where passive speakers are installed — distributing high-resolution audio with onboard amplification while remaining fully integrated with the rest of the Meridian network. See the full Meridian range we stock.

Amplification and Sources

Two onboard amplifier channels deliver clean, cool-running power from a form factor that makes no concessions on audio quality. The analogue outputs support 2.1 configurations — a pair of speakers plus a subwoofer, driven from a single 251 in one zone.

Source compatibility:

• Roon Ready — full Roon endpoint, including DSP and multi-zone management
• Sooloos — Meridian's music management and TIDAL hi-res streaming platform
• MQA decoding — unfolds MQA masters from Tidal Masters and other MQA sources
• Digital and analogue inputs — accepts a broad range of source types
• Web-based configuration — set up and managed via browser without specialist software

IP and IR control integration allows the 251 to operate within third-party control systems (Crestron, Control4, and others), making it straightforward to include in professionally installed multi-room projects.

Technical Specifications

Who Is It For?

The 251 is for zones in a distributed Meridian system where passive speakers are fitted and a separate power amplifier is unnecessary. It suits utility rooms, bedrooms, or secondary spaces where the 218 feeds DSP speakers but the zone in question runs passive speakers from a compact unit. For zones needing more amplifier channels, the 258 Power Amplifier provides eight channels in a similarly compact 1U chassis.
