861V8 Reference Digital Surround Sound Controller
Total Performance and Flexibility
The Meridian 861 sits at the heart of the theatre, linking all of your audio sources such as Blu-ray disc players, at the highest quality. Featuring our patented filter which makes standard resolution sources sound like high-resolution and Meridian Room Correction (MRC), the 861 also adds extensive connectivity including the award-winning Meridian Sooloos. Its modular approach delivers complete isolation between analogue and digital signals for world-leading performance.
A reference Sooloos zone delivers pristine lossless audio quality for all your music.
Unique Meridian High Resolution up-sampling offers the best possible performance from all of your sources.
Re-clocking of the digital audio signal removes timing errors for superior clarity and resolution.
Multiple outputs which enable the creation of both passive and DSP based systems from the same Surround Controller.

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.
Room shape, size, furnishing and loudspeaker positions all influence the sound of any system. The result is often uneven sound - low frequencies are too loud in some places and too quiet in others. Meridian's Room Correction system uses powerful DSP to smooth out uneven room resonances for clearer sound and better imaging.
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.
Music, movies and other sources each need their own settings to play correctly. Usually you have to select the right settings yourself. A Meridian system, however, analyses the incoming content and automatically selects the correct group of settings – we call them presets – for the source. You just sit back and enjoy the experience.
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.

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.
