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, and Roon Tested compatibility 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 Tested — compatible as a Roon endpoint for multi-zone playback 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.

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. Buying from Martin's Hi-Fi Martin's Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind. We have a long-standing relationship with Meridian and extensive experience designing multi-room systems around Meridian's zone controller and amplification range. We can advise on zone architecture, source routing, and integration with control systems.
