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.

Key Features:

IP Control allows for seamless integration and flexibility within the home.
MQA delivers master quality audio in a file that’s small enough to stream or download.
Lip Sync realigns audio and video following separation to ensure that there is no delay.
Meridian High Resolution [MHR] allows the secure movement of high resolution digital audio, without degradation or loss in quality.

IP Control
IP Control allows for seamless integration and flexibility within the home. Also includes both digital and analogue inputs and outputs.

Master Quality Authenticated (MQA)
Sourced from the original studio master recording as approved by the creative team, MQA combines an advanced new digital sampling technology that captures extremely high frequency timing and detail in an audio signal with an equally novel system to “encapsulate” that data into a form for delivery using any lossless file format or streaming. The listener’s decoder reconstructs the entire original signal, bringing up an indicator confirming that what they are hearing is exactly the same as the original master. Without the decoder, the listener enjoys CD quality reproduction. Its most advanced form, “MQA Studio”, uses the technology in the studio to generate an even higher quality master recording as the source.

Lip-sync
Video processing typically delays the picture. As sound travels slower than light, the effect of the sound arriving before the picture is highly noticeable. For installations where the audio and video are separated before video processing, the Meridian 218 has adjustable audio delay to realign the audio with the video.

DSP Upsampling Filter Options
The Meridian Ultra DAC is our first product that gives the ability to select between three DSP upsampling filter options when playing back standard resolution audio files. This function relates directly to the material you are playing as opposed to the genre. The options include long, medium or short filters:

Long: A filter with more stages, giving a steeper response. It removes artefacts created by pre-echo or noise in the recording and mastering process, giving a more musical sound where artefacts are present.

Medium: A good compromise between removing artefacts and preserving spatial information.

Short: A filter with fewer stages, giving a shallower response. It provides the best time response, emphasising the spatial cues in well recorded music.

Digital Signal Processing
As pioneers and leaders in the field of Digital Signal Processing (DSP) technology, Meridian is able to deliver your music authentically to recreate the passion and involvement of your musical moments. Power-efficient, active DSP crossovers are individually tailored to distribute music to each speaker, bringing your music to life.

FIFO Buffering
Each sample of a digital recording must remain evenly spaced in time. Unfortunately, timing can vary, especially when reading discs. This is “jitter”, degrading music's sense of space and diminishing realism. Meridian's multiple “First In, First Out” buffering system minimises jitter, ensuring perfect timing and improved clarity. You enjoy a clearer feeling of the instruments and their interrelationship.

SpeakerLink
Traditional audio systems often require large, expensive cables to maintain their performance. Meridian's SpeakerLink uses an “Ethernet style” cable that delivers pristine digital sound and control down a single cable between Meridian components. The result is simple, unobtrusive, and cost-effective cables that are easy to install
