DSP7200.2 Digital Active Loudspeaker
DSP7200.2 is a full range floorstanding loudspeaker which adopts the same cabinet design and technology principles as the flagship DSP8000. The latest edition, our DSP7200.2, takes this technology to a new high, with a series of technological innovations that deliver superior performance in many areas.
Built by hand in the UK, each Meridian DSP7200.2 Digital Active loudspeaker features the latest Digital Signal Processing (DSP) technology. This ingenious, yet elegant design means that the loudspeaker enclosure contains the entire system’s electronics including four custom drivers, four amplifiers and advanced sound-shaping DSP computers in each cabinet.
From medium sized rooms to more spacious environments, the DSP7200.2 fits in perfectly and delivers an outstanding and powerful performance.
Outstanding performance. Four powerful wide range 150W amplifiers deliver a maximum output level of 118dB at 1m.
Advanced, high-efficiency composite dome tweeter.
Listener controls including time-compensated balance, listening axis and Enhanced Bass alignment – enables considerable speaker placement flexibility.
On-board DSP provides thermal and dynamic bass protection – enables high level use for prolonged periods of time.

With its extensive Research and Development programme Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products.
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.
Filters are critical in digital audio. Commonly they introduce distortion and harshness because of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.
The traditional setup – amplifiers driving passive loudspeakers – is inefficient, limiting sound quality. Meridian loudspeakers contain a complete, matched audio system with efficient DSP crossovers, multiple DACs and driver-specific amplifiers, giving higher overall quality, less power use, and the performance of a traditional loudspeaker eight times the physical volume.
Loudspeaker enclosures often vibrate, colouring the sound, making it less lifelike. Our most advanced loudspeakers use a cabinet construction material unique to Meridian: Meridium features highest-grade laminated plywood layers bonded to an aluminium core, allowing the loudspeaker to reproduce music accurately without adding its own sound.
High or low, all sounds travel at the same speed, so all the sounds from a live musical event arrive at your ear at the same time, whatever frequencies they contain. Loudspeakers, however, have a problem when playing low frequency sounds at the same time as mid and high frequencies – the bass arrives late, and the deeper the sound, the later it arrives. This delayed bass causes music to lose its impact and reduces the sense of the recorded space – it is often described as “boomy”.
The goal is to have time-accurate loudspeakers, where all reproduced frequencies start and end at the same time. In a loudspeaker, this timing is affected by the crossover, driver, and enclosure type. To eliminate the delay between low, and mid and high frequencies, Meridian has designed a combination of digital filters and time delays for the mid and high frequencies. This solution enables the mid and high frequencies to “wait” for the low frequencies, delivering perfectly-timed music playback.
Mid and high frequencies are delayed to time-align them, while upper bass is delayed with a special type of patented filter. These features must be implemented entirely in the digital domain, making them impossible to achieve in any passive or analogue-active loudspeaker design.
Enhanced Bass Alignment provides accurate time-alignment of the drivers in the system, delivering exceptional imaging and a clear, transparent, more life like sound.
MHR was the first approved encryption method for transferring high definition digital audio between components. Previously, it had to be in the analogue domain, reducing quality. MHR allows secure movement of high resolution digital audio within a Meridian system, without compromise, improving quality by reducing cyclic repetition.

PIONEERS OF HI-RES AUDIO
Uses a complex digital filter to double the rate of samples from the source to improve resolution of the finer details in the record. This means that even with a standard source such as CD using our upsampling technology we are able to significantly enhance the listening experience.
A patented Meridian audio format that combines high bandwidth, security and low jitter. MHR gets the highest possible sound quality in playback systems that use Meridian and enables the encoded transmission of PCM, MQA and DSD.
