MERIDIAN C SERIES
PRELIMINARY
C61R Digital Surround Controller
Versatile, rack-mounted digital surround processor with Meridian Room Correction, based on the G61R
Includes Meridian’s powerful
Room Correction system
Meridian’s C Series offers a range of robust, precision-made audio/video components
designed with the custom installation market in mind, extending Meridian’s strong
reputation for the highest possible audio and video quality into new areas.
5 digital optical and 6 digital
coax stereo inputs
5 stereo analogue inputs
The line includes power amplifiers, surround processors and all the building-blocks of a
powerful system for custom installation applications. All are fitted with rack-mounting
ears and are equipped with remote control capability where appropriate.
10 digital surround and 8 ana-
logue surround outputs
The elegant matte-black rack-mount enclosures include a transparent front panel inset
which can be removed for access.
Analogue and 2 digital
multichannel inputs
The C61R is a rack-mounted processor
based on Meridian’s extremely popular
G61 Digital Surround Controller,
optimised for custom installation
applications. It, in turn, is a development
of the successful G68, which itself
builds on the technology that went
into Meridian’s flagship, AAA-rated
861 surround processor, and includes
the award-winning Meridian Room
Correction system to manage room
reverberation and improve the overall
listening experience.
reconfigurable for an incredible degree
of flexibility, and analogue inputs are
converted to digital at high resolution –
24-bit, 96kHz.
Powerful DSP engine with
four processors delivering
over 500MIPS
The C61R combines controller and
surround processor functions, meeting
the latest THX Ultra 2 specifications and
including the latest superb-quality AAC,
MPEG, DTS, Dolby, Trifield and Ambisonic
(both 2-channel UHJ and B-Format, to 4,
5, 6 or 7 speakers) decoding. The decoders
consist almost exclusively of our own
code, giving them superior integration
with the Meridian design philosophy, as
well as superior performance.

At the heart of the C61R is a powerful
DSP engine consisting of three Motorola
56367s and a 56371 running at 150MHz
– delivering in excess of 500MIPS (million
instructions per second). Processing is
performed at high sample rates and with
48-bit precision throughout, ensuring
that all filtering, processing and other
operations are carried out far, far
above the limits of human hearing. The
C61R is thus ideal for the very latest in
digital audio. For superior audio quality,
incoming analogue signals are converted
to 24-bit, high-sample-rate digital data
via multibit Delta-Sigma converters as
soon as they enter the processor, and all
digital signals are reclocked to minimize
jitter and maintain total data integrity.
The C61’s ‘Smart Source’ feature
continually monitors the digital inputs
and automatically loads the correct
decoding software for the format,
speaker layout and encoding of the
incoming signal. This capability is
enhanced by MHR SmartLink, which
provides a digital link between a Meridian
optical disc player and processor, carrying
explicit information about the nature of
the datastream.

You can also store separate user
parameters for each source (such as DVD)
depending on whether the incoming
signal is stereo or surround, so that any
source material is played with the DSP
mode of your choice.
The C61R includes two 6-channel S/PDIF
digital inputs (coax), four stereo Toslink
optical inputs, and six stereo coax digital
inputs. There is also a USB Audio input,
allowing a computer system to be hooked
up directly for audio replay, the processor
being seen as an external audio device
by the computer. In addition, there’s
a 6-channel analogue input, and five
stereo analogue ins. All the inputs are
The C61R features eight analogue
outputs for front, rear, centre and sub
connections, plus two additional outputs
for other applications. Ten digital
surround outputs are provided, including
front, rear, side, centre/sub and again
include an additional output pair.
