features such as Centre Elevation – which

allows the image height of a compatible

centre-channel loudspeaker to be elevated

to the centre of the screen, for example,

when mounted beneath it – and Enhanced

Bass Alignment, which ensures that all

bass frequencies are time-aligned.

With both digital and analogue output

capability, the 861 is also ideally suited

to driving conventional ampliﬁers and

passive loudspeakers. 861v8’s analogue

outputs include improved DSP with ﬁlter

optimisation, giving a sweeter sound than

ever before.

Digital Media System Integration

The optional ID41 Card delivers the highest

possible playback quality from a Meridian

Digital Media System as well as offering

Stop/Play/Previous/Next control of the

current Play Queue from the MSR+ remote

control.

In addition to Meridian Digital Media

System compatibility, the 861 includes

a built-in USB input, allowing the 861 to

replay computer sources at the highest

possible quality, limited only by the source

material.

What makes 861 so special?

The single most important feature in all our

DSP products – including the 861 – is the

incredibly high standard we set for sonic

performance.

Instead of using chips that have their

ﬁrmware irrevocably ‘burned into’ them,

Meridian’s signal processing is software

based, and therefore can be improved or

modiﬁed in future – for example, Dolby, DTS

and THX speciﬁcations have all advanced

a great deal since the initial standards were

set. Meridian’s solution gives the customer

exceptional value over the years to come

– a Meridian 800 Series system does not

go out of date. Most important, however, is

the quality sound resulting from including

highly accurate decoding algorithms at the

heart of the surround decoder. Signals are

processed with 48-bit precision where

possible.

Smart Source functionality

With the profusion of formats that may

appear at the inputs of a decoder, there is

room for confusion. The 861 continually

monitors the active digital input and

automatically loads the correct decoding

software for the format, speaker layout and

encoding of the incoming signal. You can

also store separate user parameters for

each source, depending on whether the

incoming signal is stereo or surround.

These capabilities are enhanced by

MHR SmartLink and MMHR (Meridian

Multichannel High Resolution), which

provide a digital link between a Meridian

source and controller, carrying explicit

information about the nature of the

datastream as well as encrypted high-

resolution digital signals.

Bass Management

The 861’s bass management system

ensures that all bass signals are fed to

the speakers that can handle them –

seamlessly and optimally, irrespective of the

channels from which they originate.

Movie soundtracks have the potential to

require a 12dB increase in bass power-

handling in a system. Not only can the

LFE (Low Frequency Effects – the ‘0.1’ in

‘5.1’) channel convey 10dB more bass, but

potentially this can coincide with full bass

level in the other ﬁve channels. Although the

Dolby Digital, DTS and MPEG encoders

limit the total bass level to +15dB, the

resulting bass energy can still be incredibly

demanding for even the very best systems.

This amount of bass energy may also

be disastrous for other, less capable,

speakers.

The Meridian 861 incorporates a highly

sophisticated series of bass management

schemes for Digital Surround formats. The

user can control the overall amount of LFE

added in, with Music and Movie modes

that address the fundamentally different

approaches to bass management that

these sources may require. In addition, the

861 has a bass limiting function ensuring

that the total amount of bass passed to the

system does not exceed operational limits

of the downstream components.

The 861 continually monitors all active

speaker feeds. Sophisticated DSP

determines how hard each individual

speaker is working and compares that

to a capacity rating for each speaker,

measured when the system is installed,

via a calibration routine that actually tests

the speaker’s capabilities. If the signal

demands more bass than a speaker can

supply, a proprietary, psychoacoustically-

The press on Meridian’s 861

“Brilliant in conception, mind-boggling

in execution, more powerful and better-

sounding than almost anything else ever

made.”

—What Hi-Fi

“…the 861 is beyond reproach.…There is

no need for discussion, it is simply the best.”

—Home Entertainment

“A life-changing experience…”

—The Absolute Sound

“…the best AV technology that money can

buy… a benchmark to which all others can

be judged.”

—Audio & Video Lifestyle

“…the most ﬂexible and capable device

in audio. …it offers as much insurance

against the winds of technological change

as is possible. It’s a formidable machine.”

—Stereophile

“…this ‘reference-grade’ pairing [of 800

& 861] is top-notch. …the strength of

these components is their ability to… take

domestic sound reproduction to a new level

of enjoyment and involvement.”

—Hi-Fi Choice

“Has the 861 brought me the best playback

to date I have heard in my own home and

in my room? Without a doubt it has by far.

The 861 is a technological tour-de-force…

the reference standard … Meridian Room

Correction… places the 861 into the

realm of truly reference grade products.

Meridian’s ﬂagship processor is a great

product… a leading contender for the best

preamp/processor on the market.”

—Widescreen Review

“The 861 has always been and still is:

the best-sounding audio processor I have

heard.”

—Stereophile

“If you wanted to make the argument that

the Meridian 861 was the best-sounding

AV preamp money can buy – I wouldn’t

argue with you. It’s that good.”
