Movie sound

861v8 includes an MMHR (Meridian

Multichannel High Resolution) input

allowing eight channels of audio to be

sourced from a Meridian HD621 with a

single RJ45 cable plus Meridian Comms.

The 3D-compatible HD621 is designed

to maximise audio quality from HDMI-

equipped High Deﬁnition sources such

as Blu-ray Disc players. It splits audio and

video components and sends them to the

Controller and the display respectively.

There’s simply no better way to get the very

highest audio quality from HD sources.

Dolby Digital (AC-3) remains a common

sound format on video, and the unique

Meridian Dolby Digital decoder in the

861 delivers the highest quality sound of

which this format is capable. The 861 also

decodes MPEG and DTS signals from DVD

– as well as DTS surround CDs.

Improved performance

Meridian’s 861 uses carefully-crafted

processing to gain the maximum beneﬁt

from high-precision PCM inputs. The 861

accepts multiple input channels of 24-bit,

96kHz sampling PCM, and delivers the

maximum resolution on these signals.

The processor also performs improved

high-resolution up-sampling on signals

coming in at lower sampling rates,

de-jittering them and signiﬁcantly

improving their audio quality. Meridian’s

acclaimed ‘apodising’ upsampling ﬁlter

and redesigned oscillators and clocking

structure new to 861v8 reduce jitter by

40%, signiﬁcantly improving audio quality

for all sources managed by the 861.

SpeakerLink in and out

Meridian’s SpeakerLink technology allows

two channels of balanced digital audio plus

all associated Meridian Comms and control

signals to be carried between components

via a single, low-proﬁle, inexpensive

Screened Twisted Pair (STP) cable.

861v8 includes three SpeakerLink inputs

for the connection of components like

the 808 CD Player, and a full eight

channels of SpeakerLink out – able to

drive a complete Meridian Digital Theatre

consisting of Meridian’s high-performance

DSP Loudspeakers – making the 861

particularly easy to specify and to install.
