About this AV receiver
The 540R is designed to maximise multi-channel performance without
compromising on stereo reproduction. As such, the six, 80W discrete
amplifiers are kept as separate as possible from the processing and
input stages. An oversized power supply ensures that the 540R can
maintain a high power output into difficult electrical loads to ensure a
powerful and effortless sound.
A full range of Digital and analogue inputs are fitted to the 540R. The
four Digital inputs allow for the connection of suitably equipped DVD
players, satellite boxes and games consoles for decoding into digital
surround formats. In addition, there are conventional stereo inputs for
CD players and the like to ensure the best possible stereo reproduction.
The 540R is also capable of decoding your stereo sources in Dolby Pro
Logic
®
II (Pro Logic is a registered trademark of Dolby Laboratories), for
a convincing and effective surround experience from a stereo source.
This ensures sources such as analogue televisions and VCR's can make
full use of the 540R's surround capabilities.

In addition to the stereo analogue input, the 540R also carries a seven-
channel analogue input. This feature allows for the connection of a DVD
Audio or SACD equipped player to the 540R. This means that the 540R
is fully equipped to make the most of these exciting new music formats.
As well as the full complement of audio inputs, the 540R also performs
Composite, S-Video and Component Video switching. This means that
the 540R can be used as a hub to carry video signals in addition to the
audio ones. For example, this would enable two Component Video
equipped items to be connected to a single component input on your
television or monitor, meaning more items can be connected to fewer
high quality inputs on your television.
Last, but by no means least, is the fitment of pre-outs to the 540R. This
means that an existing stereo amp can be retained to drive the front
channels or indeed every channel can be driven by a separate power
amplifier and the 540R simply used as a processor and pre-amp. This
feature allows for the retention of existing quality stereo amps and
allows for a degree of additional upgrading.

IMPORTANT SAFETY INSTRUCTIONS
Read and follow instructions - All the safety and operation instructions
should be read before use.
Retain instructions - These instructions should be retained for future
reference.
Heed warnings -
Comply with all warnings on the 540R and in the
manual.
Cleaning - Unplug the 540R from the wall outlet before cleaning. Do not
use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
Grounding and polarisation - The 540R may be equipped with a
polarised alternating current line plug (a plug having one blade wider
than the other). This plug will fit into the power outlet only one way. This
is a safety feature. If you are unable to insert the plug fully into the
outlet, try reversing the plug. If the plug should still fail to fit, contact your
electrician to replace your obsolete outlet. Do not defeat the safety
purpose of the polarised plug. (North America Only)
Overloading - Do not overload wall outlets or extension cord as this can
result in a risk of fire or electric shock. Overloaded AC outlets, extension
cords, frayed power cords, damaged or cracked wire insulation, and
broken plugs are dangerous. They may result in a shock or fire hazard.
Power sources - The 540R should be operated only from the type of
power source indicated on the marking label. If you are not sure of the
type of power-supply to your home, consult your product dealer or local
Power Company.
Accessories - Do not place the 540R on an unstable
surface or shelf. The amp may fall, causing serious
injury to a child or adult as well as serious damage
to the product.
Outdoor antenna grounding - If an outside antenna or cable system is
connected to the product, be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges and
built-up static charges. Section 810 of the National Electrical Code,
ANSI/NIPA No. 70-1984 (section 54 of Canadian Electrical Code, Part 1)
provides information with respect to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna-
discharge unit, size of grounding conductors, location of antenna-
discharge unit, connection to grounding electrodes, and requirements
for the grounding electrode.
Power cord protection - Your power supply cord should be placed so that
the power lead is not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at Wall plugs
and where the power lead exits from the 540R.
Contact the service department should any of these conditions occur:
Lightning - For added protection during a thunderstorm, or when it is left
unattended and unused for long period of time, unplug the 540R from
the wall outlet and disconnect the antenna or cable system. This will
prevent damage to the 540R from lightning and power-line surges.
Heat dispersion - Leave at least 10 cm of space between the top, back
and sides of the 540R and the wall or other components for proper
ventilation.
Notes on use
Avoid high temperatures, allow for sufficient heat dispersion when
installed on a rack.
Handle the power cord carefully. Hold the plug when unplugging the
cord.
Keep the 540R free from moisture, water and dust.
Unplug the power cord when not using the 540R for long periods of time.
Do not obstruct the ventilation holes.
Do not let foreign objects, or liquids to get into the 540R.
Never disassemble or modify the 540R.
IMPORTANT
If the 540R is run at a very high level, a sensor will detect a temperature
rise and show "PROTECTION OVERLOAD" on the display. The 540R will
then go into stand-by. It cannot be switched on again until the
temperature has fallen to a more normal level
Plug fitting instructions (UK only)
The cord supplied with the 540R is factory fitted with a 13Amp mains
plug fitted with a 13Amp fuse inside. If it is necessary to change the
fuse, it is important that a 13Amp one is used. If the plug needs to be
changed because it is not suitable for your socket, or becomes
damaged, it should be cut off and an appropriate plug fitted following
the wiring instructions below. The plug must then be disposed of safely,
as insertion into a 13Amp socket is likely to cause an electrical hazard.
Should it be necessary to fit a 3-pin BS mains plug to the power cord the
wires should be fitted as shown in this diagram. The colours of the wires
in the mains lead of the 540R may not correspond with the coloured
markings identifying the terminals in your plug. Connect them as
follows:-
The wire which is coloured BLUE must
be connected to the terminal which is
marked with the letter 'N' or coloured
BLACK.
When the power-supply cord or plug is damaged.
If liquid has been spilled, or objects have fallen into the amp.
If the 540R has been exposed to rain or water.
If the 540R does not operate normally after following the operation
instructions, adjust only those controls that are covered by the operation
instructions.
If the amp has been dropped or damaged in any way.
When the amp exhibits a distinct negative change in performance.
Servicing -
Do not attempt to service the 540R yourself as removing
cover may expose you to dangerous voltages or other hazards. Refer all
servicing through your dealer to qualified service personnel.
Attachments - Do not use attachments not recommended by your dealer
as they may cause harm to the 540R.
The wire which is coloured BROWN
must be connected to the terminal
which is marked with the letter 'L' or
coloured RED
The wire which is coloured
GREEN/YELLOW must be connected to
the terminal which is marked with the
letter 'E' or coloured GREEN.
If your model does not have an earth wire, then disregard this
instruction.

Connecting loudspeakers
To avoid damaging the speakers with a sudden high-level signal, be sure
to switch the power off before connecting the speakers.
Check the impedance of your speakers. Connect speakers with an
impedance of between 4 and 8 ohms.
The 540R's red speaker terminals are the + (positive) terminals and the
black terminals are the - (negative) terminals.
The diagram below shows how loudspeaker connections are made.
Please note that all connections are made via loudspeaker cable except
the subwoofer which is connected via a standard RCA phono cable.
Dipoles diffuse the sound in a slightly different way, and therefore
have different positioning requirements: ideally they should be
mounted to the side of the listener, and up to 15 degrees above
listening height

Notes on loudspeaker placement
1.
Front left and right loudspeakers
-
These should be placed
equidistant to the left and right of your screen far enough apart to
ensure good stereo imaging. If they are too far apart or too close
to the corners of the room they will sound distracting and distant.
It may be desirable to experiment with the 'toe-in' of the units
(angling them towards the listening position) to optimise the front
speaker soundstage and imaging.
2.
Centre channel Loudspeakers
-
Ideally your centre channel
loudspeaker needs to be positioned directly above or below your
screen, facing the listening position.
3.
Surround left and right Loudspeakers
-
If you are using normal hi-fi
loudspeakers as your surrounds they should be situated roughly at
listening height and facing into the listening position. It is
suggested that they are wall mounted or alternatively placed on
suitable speaker stands.
Bipolar-type surround speakers can be set up in much the same
way as standard 'monopole' types, so try positioning around
listening height and angle toward the listener
FM antenna
If you live reasonably close to a transmitter and want to use the provided
lead-type FM antenna, connect to the "FM 75 ohm" socket, extend the
lead and attach it to a window frame or wall with thumbtacks, or move
around the room, where reception is best
In an area where FM signals are weak, it may be necessary to use a 75
ohm unbalanced-type outdoor FM antenna.
AM loop antenna
The high performance AM loop antenna provided with the receiver is
sufficient for good reception in most areas.
Connect the loop antenna's wires to the AM antenna terminals.
Place the antenna on a shelf, for example, and move around to obtain
the best reception, place as far away as possible from the entire system,
speaker leads and the power cords, to prevent unwanted noise.
If the AM loop antenna provided does not receive sufficient reception, it
may be necessary to use an outdoor AM antenna.

Connecting video source equipment
Video connections
There are three ways in which video connections to the 540R can be
made (only one video connection should be made):
Component -
Connect video source equipment’s Component sockets to
the corresponding sockets on the rear of your 540R using Component
cable (3RCA-3RCA)
S-Video - Connect video source equipment’s S-Video socket to the
corresponding socket on the rear of your 540R using S-Video cable
(MINIDIN-MINIDIN).
Composite - Connect video source equipment’s Composite socket to the
corresponding socket on the rear of your 540R using phono cable (RCA-
RCA)
For best picture quality we recommend that video connections are made
via Component sockets where possible.
Note - If connecting two pieces of video source equipment to the 540R
simultaneously (eg a VCR and a DVD player) it is recommended that the
same method of video connection is used. By doing this only one input
on the television will be used.
Video connections are shown in fig.1.
Connecting audio source equipment
Audio source equipment, such as a CD player, can be listened to through
the 540R.
Connections are made as audio connections explained in the previous
column.
Note - To record audio source material an external recording unit (eg
Minidisc) should be connected to the digital or analogue outputs on the
rear of the 540R.
Audio connections
There are three basic options for audio connections to the 540R:
Optical - Connect video source equipment’s optical digital output socket
to the corresponding socket on the rear of the 540R using optical cable
(OPT-OPT)
Coaxial - Connect video source equipment’s coaxial digital output socket
to the corresponding socket on the rear of the 540R using 75 Ohm
phono cable (RCA-RCA)
Line level audio - Connect video source equipment’s audio out sockets
to the corresponding sockets on the rear of the 540R using phono cable
(2RCA-2RCA).
If you want to listen to DVD Audio or SACD discs then it will be necessary
to connect your DVD player to the 6.1 Direct In sockets on the rear of the
540R. Connecting a DVD player to these sockets bypasses the 540R
decoder and sends the signal straight to the built in six channel
amplifier.
Audio connections are shown in fig.2.
