SPECIAL EDITION DSP7200HC
DIGITAL ACTIVE LOUDSPEAKER
OVERVIEW
The Special Edition series of Meridian loudspeakers represent the pinnacle of Meridian’s loudspeaker design and development programme and are the most advanced loudspeakers that Meridian has produced to date. Over 30 years of engineering development, coupled with extensive research in Psychoacoustics into how we perceive sound, have informed every aspect of the Special Edition series.
Built by hand in the UK, each Meridian Special Edition DSP7200HC is a Digital Active loudspeaker containing Digital
Signal Processing (DSP) technology. This ingenious, yet elegant design means that the loudspeaker enclosure contains the entire system’s electronics including its amplification. In common with the other loudspeakers in the Special Edition series, a suite of innovative Meridian technologies is also provided.
With an ability to deliver the very best from High Resolution sources, including MQA, the performance of the Meridian
Special Edition DSP7200HC demonstrates why Meridian is widely regarded as the Pioneer of High Resolution Audio.
With all the features of the freestanding DSP7200SE, the DSP7200HSE provides full range playback in a horizontal centre channel package. The DSP7200HCSE is ideal for mounting under a large-screen TV, or behind an acoustically-transparent projection screen and in partnership with other Meridian free standing or in-wall loudspeakers.
PRODUCT HIGHLIGHTS
• New Meridian-designed short-horn-loaded tweeter with a beryllium dome for outstanding transient response and extended frequency range.
• Centre Elevation - allows the image from a centre channel loudspeaker to be raised to be in line with main left and right loudspeakers.
• New mechanical clamp rings on the mid-range and bass drivers provide enhanced mechanical stability and further minimise coloration.
• New extended-bandwidth analogue electronics, optimised to deliver maximum performance from high-resolution recordings.
• DSP provides performance enhancements including the latest implementation of Enhanced Bass
Alignment (EBA) technology to provide additional clarity and an open, transparent sound-stage.

USER FEATURES
• Source information in the loudspeaker display is also derived from the controller, allowing for additional custom legending.
• Bass, Tilt, Centre Elevation and Axis presets for enhanced control and a new lowpass crossover design.
• ‘Ethernet’ style SpeakerLink cabling which maintains performance and is easy to install.
TECHNOLOGIES
NEW SPEAKERLINK INPUT BOARD AND DSP
A new SpeakerLink board provides enhanced interoperability between Meridian Controllers and
DSP Loudspeakers. Digital Signal Processing has been enhanced for higher clock speeds, giving superb handling of the high sample rates encountered with high-resolution audio sources.
ENHANCED BASS ALIGNMENT (EBA)
Meridian’s innovative Enhanced Bass Alignment technology uses two different technologies to time-align high, mid and upper bass frequencies with the low bass, resulting in audibly improved bass transients and added life and clarity.
WIDEBAND ANALOGUE ELECTRONICS
Each amplifier has been refined to provide a more lifelike sound, with optimised transient response, extended frequency response and enhanced dynamic range.
MERIDIAN APODISING FILTER
A unique Meridian filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early, less efficient filters used in the digital recording process. The result: a better, cleaner sound from recordings both old and new.
MQA –MASTER QUALITY AUTHENTICATED
Special Edition DSP Loudspeakers fully support the revolutionary MQA process, which delivers the accurate sound of the studio – guaranteed.
FIFO BUFFERING
Meridian’s “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.

CONSTRUCTION
The Meridian Special Edition DSP7200HC is manufactured from interlaminated panels finished in high gloss piano lacquer. Black and High Gloss White are available as standard finishes. In addition custom finishes are available upon request as well as a further 270 RAL colour finishes as part of
Meridian’s Select programme.
Soft cabinet edges enhance the visual design, but they also avoid generating unwanted additional high frequency sounds that can blur the soundstage.
• The beryllium-dome tweeter is seven times more rigid than aluminium – the traditional tweeter cone material – and over twice as fast, making it the perfect material for the most natural sound.
• The new beryllium-dome tweeter uses a semi-horn-loaded approach and was designed by Meridian engineers.
• Driver clamp rings ensure that Meridian DSP
Loudspeaker enclosures are rigid and free from resonances. You hear the loudspeaker, not the cabinet.
