Meridian 251 Zone Controller With Amplifier

£1,249.00

Meridian 251 Zone Controller with Amplifier is made for in-room and in-rack systems with all the functionality needed to create a great sounding and flexible Hi-Res Audio zone.

Compatibility

With two powerful, cool-running channels of onboard amplification, the Meridian 251 can comfortably drive a pair of loudspeakers or a sound bar with trademark fidelity and high-resolution performance. With a pair of analogue outputs, you can also run a 2.1 system with a separate subwoofer.MQA–enabled Meridian 251 has both digital and analogue inputs making it a hub for distributed audio applications from simple single zone to whole-house distribution. Featuring IP and IR control, this versatile 1U, the half-width unit can be easily installed behind a TV or in a rack.

User Interface

A significant number of control options are provided on the Meridian 251 Powered Zone Controller including IP control, native iPad network control app, Meridian Sooloos Control, IR and third-party control. In addition, the unit’s front panel comprises multiple LEDs to indicate source selection.

Simple configuration via an in-built webpage to select all installation options makes for easy, repeatable and quick set up. 251 is also an endpoint for the award-winning Sooloos music management platform as well as offering support for Roon.

Functions

Video processing typically delays the picture. For installations where the audio and video are separated before video processing, the Meridian 251 has an adjustable 80ms audio delay to realign the audio with the video. Clock variations, known as jitter, are one the main causes of unpleasant “glare” in digital audio systems.

The Meridian 251 solves this problem with proprietary jitter reduction technique using a FIFO (first-in first-out) buffer that allows an independent output clock to deliver clock performance that does not rely on the incoming signal quality.

DSP Upsampling

Almost all audio has been digitally processed, even if it arrives at the Meridian 251 in analogue form. Upsampling allows the Meridian 251’s DACs to run at a higher sample rate and achieve full potential. Upsampling also provides the opportunity to apply the apodising correction to ameliorate time-domain errors that have been introduced to the signal by the ADCs or other upstream processing. MQA is supported too, this revolutionary end-to-end technology delivers Master Quality Authenticated audio in a file that’s small enough to stream or download.
