Meridian 251 Powered Zone Controller
Designed for in-room and in-rack systems, the 251 Powered Zone Controller contains all the functionality needed to create a great sounding and flexible Hi-Res Audio zone.
With two powerful, cool-running channels of on-board amplification, the Meridian 251 can comfortably drive a pair of loudspeakers or a sound bar with our trademark fidelity and High Resolution performance.
Integrated Amplifier
The Meridian 251 features two powerful, high performance, cool-running 100W Class D Amplifiers that allow this versatile 1U tall product to be easily partnered with any passive loudspeaker. Accommodating both local and distributed audio, whether analogue or digital, the MQA-enabled Meridian 251 is also an endpoint for Roon. Control features including IP and IR allow this versatile solution to be seamlessly integrated into the home.
Q-Sync
Meridian Q-Sync deploys Meridian's multiple “First In, First Out” buffering system which minimises jitter, ensuring perfect timing and improved clarity.
True Link
Meridian True Link is an encryption method for transferring high-definition digital audio over SPDIF connections. It allows secure movement of digital audio whilst ensuring that the SPDIF clock signal can be transmitted with minimum degradation.
True Time
True Time is Meridian's proprietary Apodising Filter that avoids pre-ringing and cleans up the effects of early filters, converting pre-echo to post-echo.
Digital Precision
Meridian Digital Precision maximises the signal-to-noise ratio of the digital audio, ensuring the finest details of every song are retained.
Roon Tested
Roon Tested devices are profiled by the Roon team to ensure simple setup and effortless daily use.
