Introduction
G01 Control Unit
The Meridian G01 is a fully-integrated analogue control unit which
includes a tuner module. It is an ideal complement to the G Series
power amplifiers.
Incorporating both a preamplifier and controller, the G01 Control
Unit provides seven stereo analogue inputs plus an AM/FM or
DAB/FM tuner. The AM option provides LW/MW reception, and
the FM stage provides VHF stereo band II reception with RDS. The
inputs are nominally designated Aux (phono), CD, TV, Tape, Disc,
DVD, and VCR.
Two sets of stereo tape outputs are provided, along with
two preamp output pairs, allowing maximum flexibility in the
configuration of tape/decoder loops, multi-room, and amplification/
bi-amplification. In addition to the main outputs, a stereo
headphone socket is provided on the back panel for personal
listening.
Balanced operation has always been preferred in the professional
audio industry, as it can significantly reduce hum and noise and
make the system less prone to interference. The G02 brings this
philosophy to the G Series. Incorporating both a preamplifier and
controller, the G02 Balanced Control Unit provides seven twochannel analogue inputs. Four of these – nominally designated
Aux (phono), Radio, TV, and VCR – are unbalanced, while the
remaining three – CD, Tape, and Disc – offer balanced inputs on
XLR connectors.
The internal architecture of the G02 is balanced throughout, and
the first thing that happens to an unbalanced input is electronic
balancing for maximum quality throughout the signal chain.
Two sets of unbalanced stereo tape outputs are included on the
back panel, allowing maximum flexibility in the configuration of
tape/decoder loops and multi-room capabilities. The outputs can be
configured as a single balanced output by using a suitable breakout cable.
G02 Balanced Control Unit
Two sets of main outputs are provided: the primary outputs are

ultra-low noise and distortion. Featuring a fully-balanced signal
path throughout, it is an ideal complement to the G Series power
amplifiers and is particularly suited to those who wish to maintain
a balanced analogue signal path at the very highest quality of
reproduction.
G51 Receiver
Incorporating a preamplifier, controller, and a power amplifier that
features a unique low-feedback topology and extremely low output
impedance, the G51 Receiver provides seven stereo analogue
inputs plus an AM/FM or DAB/FM tuner. The AM option provides

developments from Meridian, used in the flagship DSP8000 digital
loudspeaker systems.
The amplifiers feature active bias control throughout, with thermal
sensing that carefully manages the temperature and current flow at
different volume levels. Fully DC-coupled, the signal path contains
no unnecessary capacitors, while those in the power supplies are
audiophile grade components.
The amplifiers are of a unique low-feedback design for minimum
transient and interface intermodulation distortion, offering superb
clarity and transparency right across the audible range, with an
output impedance that is close to zero and delivers a solid 100W
continuous mean power per channel into 8Ω suitable for virtually
any high-quality passive loudspeaker system.
The amplifier, when in standby mode, maintains a standing
voltage on the power rails, reducing the time taken for optimum
General
Each of the products provides a front-panel volume knob (press
to mute), which activates a specially-designed dual differentiallybalanced volume control circuit. This ensures perfect stereo tracking
and full frequency range performance at all volume levels.
In all products the sensitivity of each input can be individually
adjusted as desired.
The Aux input can be configured for either moving coil or moving
magnet cartridge operation by the addition of appropriate phono
modules.
All phono connectors are gold plated for maximum transparency.

Troubleshooting
We expect you to achieve superb results with the control unit or receiver. 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
No blue light is displayed when switching on
• Check that the AC power supply is connected correctly.
• Check that the ON OFF switch on the back panel is in the ON
position.
The sound has cut out and there is no display (G51)
The G51 Receiver includes electronic protection, which will protect
the output if the connections are accidentally shorted.
The amplifier may have tripped the mains due to a source with an
excessive DC level.
• Check that the fuse on the product’s back panel and the fuse in
the unit’s power plug have not blown; see To change the mains
fuse, page 28.
• Unplug the source.
• Turn off the power, and then turn it on again.
There is no sound (G51)
If this restores normal operation check the source. Otherwise there

and power amplifier inputs.
dealer.
26
Tr o u b l e s h o o t i n g
The sound has cut out and the display shows Hot
(G51 only)
This indicates that the power amplifier stage of the receiver has
turned off due to overheating.
• Allow the receiver to cool down.
If the problem continues to occur there may be a fault with the
receiver, and you should consult your dealer.
Communication is not working between the G01/G02/G51
and other Meridian products
• Check that all products are interconnected using the correct
Comms leads.
FM tuner problems
FM tuner reception is poor
To obtain high-quality stereo reception on FM a good aerial is
essential. Try positioning the antenna at different points in a room;
generally performance is best high up and near a window.
In some areas a fixed antenna installation will be necessary. This
can be placed in a loft or mounted externally.
Note: For all outdoor antennae we strongly recommend you use a
qualified installer who will comply with local safety regulations.
RDS station names are not being received
Not all stations transmit the station name in all areas.
• Ensure that one of the products is the controller; see To connect
to other Meridian G Series, 500 Series, or 800 Series equipment,
If the station name is not available you can define a preset station

with a name; see the G Series System Guide.
• If the problem continues, reset the product; see Stage 1:
Resetting the product, page 18. Warning: All settings will be
lost.
There is hum
• Check your other equipment.
AM tuner problems
AM tuner reception is poor
Position the antenna to maximise the strength of the station you
want to receive and to reduce interference from other stations on
nearby frequencies.
• For turntables, check the TECHNICAL GROUND connection.
• If you are using the G51 PRE OUT/AMP IN loop with a third-party
surround controller or other product, ensure that the thirdparty product is properly earthed or bonded to the TECHNICAL
GROUND of the G51.
• If you are unable to cure the problem consult your dealer.
Position the antenna away from items that generate electrical
interference, such as fluorescent tubes and televisions.

Tr o u b l e s h o o t i n g
DAB tuner problems
The display shows “No signal”
This indicates that the tuner cannot locate a signal for the selected
service.
• Check that the antenna is connected correctly and reselect a
service.
You may need to use a better aerial.
This may also indicate that a stored ensemble is no longer
available, either because the tuner has been moved to a different
area of the country, or because the transmission has ended.
• Perform a scan to rebuild the list of services.
The display shows “Weak signal”
This indicates that the reception is poor.
• Try moving the aerial to improve reception, or fit a better aerial.
The display shows “No Services”
This indicates that a list of available services has not been built.
• Perform a scan to build a list of available services.

Tr o u b l e s h o o t i n g
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. Dust can be
removed from the disc drive tray with a small dry brush when the
drawer is open.
Ensure that no liquid enters the casework and that the product is
completely dry before re-connection.
To clean the audio connections
The audio sockets on the back of the product are gold plated and
do not need to be cleaned if gold-plated 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.
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.
