Introduction
This guide provides full information about unpacking the C61R Digital Surround Controller,
connecting it to the other equipment in the system, and configuring it using the front panel.
Once you have connected and configured the product, refer to the G Series System Guide for
information about operating it.
The C61R is a powerful, flexible surround controller, with 8
unbalanced analogue outputs and 10 digital outputs.
At the heart of the C61R is a powerful DSP engine consisting
of three Motorola 56367s running at 150MHz – delivering an
incredible 450MIPS (million instructions per second) capability.
Processing is performed at high sample rates and with 48-bit
precision throughout, ensuring that all filtering, processing, and
other operations are carried out beyond the limits of human
hearing. The C61R is thus a perfect processor for the very latest in
digital audio, such as DVD-Audio and DVD-Video.
Inputs
Analogue signals are converted via a 24-bit Delta-Sigma converter
to high-sample-rate digital on input to the processor, while all
digital signals are reclocked to minimise jitter and maintain total
data integrity. The C61R includes two six-channel S/PDIF digital
inputs (coax), a USB audio input, four TOSlink optical inputs, and
six more stereo coax digital inputs. In addition, there is a six-
channel analogue input, and five stereo analogue inputs.
Formats supported
The C61R combines controller and surround processor functions,
meeting the latest THX specifications and including MPEG, DTS,
Dolby, Trifield, and Ambisonic decoding. In many cases the decoders
incorporate our own code, giving them superior integration with
the Meridian design philosophy, as well as superior performance.
As a result, the C61R can decode surround signals from all PCM
optical discs. The C61R is thus an ideal complement to a G Series
optical disc player like the G98.
Smart Source feature
The C61R’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,

Introduction

carrying explicit information about the nature of the datastream as
well as encrypted high-resolution digital signals from DVD-Audio
– the first system of its kind to be approved. Virtually all other
manufacturers oblige you to go through an analogue connection,
losing quality in the process.
You can also store separate 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.
Meridian Room Correction
The C61R incorporates Meridian Room Correction, a unique system
that compensates for acoustic deficiencies in your listening room,
particularly at the bass end. It achieves this by automatically
analysing the room response and then using powerful Digital
Signal Processing (DSP) technology to build a set of filters, called a
profile. This audibly improves the sound by eliminating resonances
and making the decay time consistent for frequencies below about
250Hz.

• Use the Comms part of an M5 lead to connect one of the
COMMS sockets on the C61R to the digital speaker you have
chosen as the master (typically the centre speaker).
• Use the audio part of the M5 lead to connect the digital speaker
to the appropriate digital output socket.
If the system includes more than two Meridian DSP loudspeakers
you may use a 511 S-patch box (available separately) to link
together the S5 leads from each speaker.
• Connect the COMMS output from the master digital speaker to
one socket on the 511 using an S5 lead.
• Link each pair of speakers together with an S5 lead, out of
the first speaker and into the second speaker, as shown in the
diagram.
• Connect the inputs to the first speaker of each additional pair
to the 511 (Comms) and the appropriate output of the C61R
(audio), using an S5 lead.
The speakers should then be configured appropriately as master
and slaves, and Left, Right, Centre, Surround; see Meridian DSP

either the digital or analogue subwoofer outputs of the C61R. The
analogue connection must be used if you do not have a digital
main speaker.
• Connect the SUB analogue output socket from the C61R Digital
Surround Controller to the subwoofer’s line-level input using a
phono lead.
Use RZ and LZ if you have two subwoofers.
The digital surround controller provides a very high-quality
crossover for the subwoofer, and for best results you should use
this instead of the subwoofer’s crossover. To do this remove any
crossover in the subwoofer or set it to its highest setting (eg
200Hz). The subwoofer crossover can be set from the front panel of
the C61R; see Subwoofer crossover frequency , page 32.
