Introduction
This guide provides full information about unpacking the G61R 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.

optical disc player like the G98.
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 G61R includes two six-channel S/PDIF digital
inputs (coax), a USB audio input, four TOSlink optical inputs, and
Smart Source feature
The G61R’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,

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 G61R 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.

Calibrating

Calibrating the system
To help you to set up the installation to give the best possible sound with any particular
combination of associated equipment, the G61R Digital Surround Controller includes a built-in
calibration procedure.
This calibration procedure uses test signals to present a series of sounds, which you use to
adjust certain aspects of the system to their optimum settings.
You should use the calibration procedure the first time you set up the system, and whenever
you want to check the calibration, such as after changing the layout of the room.
Introduction
We recommend that you perform the calibration procedure using
the MSR+ and from the listening position.
As you run the calibration procedure the name of each calibration
test is shown on the front-panel display, followed by the
parameters adjusted in the test.
Each calibration test uses a test signal designed to give the best
results.
Using a Sound Pressure Level meter
Although you can perform the calibration procedure by ear, it is
recommended that you perform the tests using a Sound Pressure
Level meter. These are available fairly cheaply from Tandy/Radio
Shack, or your Meridian dealer may be able to lend you one.
Set the Sound Pressure Level meter to C weighted, and Slow. Take
readings with the meter at the listening position, pointing vertically.
You should hold the meter with an outstretched arm to minimise
reflections from your body.
You can choose to display and enter distances in either feet and
inches or metres.

DSP presets
This chapter gives details of the DSP presets and their parameters, and describes how to
modify them.
DSP presets
The G61R Digital Surround Controller provides two types of DSP
preset. One set is available if the input is two-channel; eg from a
traditional stereo source or a two-channel DVD-A. The other set is
available if the input is 5.1 or 6 channels of discrete audio; eg from
a Dolby Digital DVD-V or a music DVD-A. The DSP presets available
in each set are described in the following pages.
Speaker layouts
The G61R Digital Surround Controller provides great flexibility in
the way in which you use the loudspeakers in your system. For
example, the speaker step of the Configuration Wizard allows
you to use the subwoofers and centre speaker only for movie
material see Configuring speakers, page 20. With the Meridian
Configuration Program you can specify three different speaker
layouts, each with a different use of subwoofers and centre
speaker:

DSP presets for two-channel material
for the fact that the frequency response of human hearing changes
with direction.
The G61R provides several signal processing options for twochannel material. The Music DSP presets are designed for use with
music from sources such as CD, radio, or two channel DVD-A:

The G61R Digital Surround Controller will automatically select the
right decoder algorithm and present the same set of preset choices
for all streams. Note: Some presets are only available if there are
four surround speakers in the system.
There are four multichannel Music presets:
•Discrete, PLIIx Mus6, THX Music, and Ambisonics B format

Ambisonics
The Ambisonics preset allows you to decode multi-channel sources
which have been encoded in Ambisonics B format.
Ambisonics B format contains four independent channels of
information to give a three-axis representation of the sound at the
recording position. The signals are: mono sound pressure, left-right
velocity component, front-back velocity component, and up-down
velocity component.
Using dynamic range control
If the input format is Dolby Digital, the 5.1 Movie DSP presets
provide an additional Compress parameter to allow you to take
advantage of the dynamic range information provided in the
Dolby Digital format to provide dynamic range control without the
distortion involved in analogue methods.

Troubleshooting
We expect you to achieve superb results with your digital surround controller. If, however, you
encounter any problems, either when installing and configuring it, or during operation, please
check the following pages for suggested solutions.
If these suggestions fail to cure the problem, please contact your Meridian dealer for further
assistance.
General operating problems
Standby light not lit
•Check that the AC power supply is connected correctly.
•Check that the ON OFF switch on the back panel is in the ON
position.
If the light still does not illuminate, check any fuses in your power
supply and the fuse in the inlet of the G61R. If these are all intact,
contact your dealer.
Erratic or unexpected system behaviour
Redo the Auto Configure process as follows:
•Put the whole system into standby.
•Make sure you are operating the MSR+ from a position where all
the units can receive the infra-red.
•Press Clear on the MSR+.
•Observe all units responding correctly.
In extreme cases, the memory of the G61R may have been
corrupted. If this is suspected perform a full reset; see Resetting the
product, page 18.
48
Tr o u b l e s h o o t i n g
Remote not working
Check the following:
•The battery in the MSR+.
•Remove the Comms connections from the G61R and check
whether it responds now. If so, replace the connections and
perform an Auto Configure procedure; see To connect to other
Meridian G Series, 500 Series, or 800 Series equipment, page 15.
•See if the G61R has been set up as Not Controller in the
Configuration Menu; see Configuring other settings, page 24.
Note: This may be deliberate by your dealer.
When playing a Dolby Digital DVD, the G61R selects a
two-channel preset
DVDs include a two-channel Dolby Digital soundtrack, which will
use the default two-channel preset.
•Select a six-channel soundtrack, if it is available.
Unit is overheating
Check that there is adequate ventilation around the unit.
Audio problems
Hum on analogue input
•Check the source equipment. Disconnect each source in turn.
•If the hum originates from a ground loop, an antenna or cable
supply may be the cause. In this case an antenna-lead isolator
should be fitted.
•If the G61R seems to be the cause of hum consult your dealer.
There is radio interference
The G61R is a digital audio and computing device which has been
designed to very high standards of electromagnetic compatibility.
If this equipment does cause or suffer from interference to/from
radio or television reception then the following measures should
be tried:
•Reorient the receiving aerial (or antenna) or route the antenna
cable of the receiver as far as possible from the G61R and its
cabling.
•Ensure that the receiver uses well-screened antenna cable.
•Relocate the receiver with respect to the G61R.
•Connect the receiver and this product to different AC outlets.
•If the problem persists contact your dealer.

Maintenance
Cleaning
To clean the case, display panel, and keypad
•Disconnect the power cord before cleaning the unit.
The exterior surfaces of Meridian G Series products are made from
solid anodised aluminium, powder coated steel, thermoplastic
rubber, and glass.
They are designed to be easily wiped clean with a dry, lint free
cloth. Greasy marks should be removed by light rubbing with a
slightly damp cloth and a trace of proprietary glass cleaner. Do not
use any other solvent or abrasive based cleaners.
Ensure that no liquid enters the casework and that the product is
completely dry before re-connection.
To clean the audio and video connections
The audio and video sockets on the back of the product are gold
plated and do not need to be cleaned if gold-plated phono plugs
are used. Otherwise, it is recommended that you unplug and
reconnect the plugs at least once a year. A proprietary contact
cleaner can be used to some advantage.
The electrical digital output should be treated in a similar way.
Tr o u b l e s h o o t i n g
To change the mains fuse
•Remove the mains connector, and pull out the drawer above the
power input to access the fuse.
Before replacing a blown fuse, it is best to ascertain the cause of
the failure.
The fuse drawer includes a spare fuse. This should be replaced by a
fuse of the same rating.
