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.  
Now we invite you to sit back, relax and enjoy!

540R AV receiver  
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  
Connecting loudspeakers  
To avoid damaging the speakers with a sudden high-level signal, be sure  
to switch the power off before connecting the speakers.  
4. Surround centre speaker - Required for enjoying Dolby® Digital EX  
(Dolby is a registered trademark of Dolby Laboroatories) or DTS®-ES  
audio (Under license from Digital Theater, System, In, or DTS (BVI)  
Limited). Improves the quality of sound effects by filling the gap  
between the surround left and rear right 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.  
5. Subwoofer - The location of any dedicated subwoofer will greatly  
effect the quantity and also the quality of the low frequencies.  
Please see dedicated subwoofer manual for detailed positioning  
information.  
Please note that all connections are made via loudspeaker cable except  
the subwoofer which is connected via a standard RCA phono cable.

Notes on loudspeaker placement  
FM antenna  
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.  
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.  
2. Centre channel Loudspeakers - Ideally your centre channel  
loudspeaker needs to be positioned directly above or below your  
screen, facing the listening position.  
AM loop antenna  
The high performance AM loop antenna provided with the receiver is  
sufficient for good reception in most areas.  
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.  
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.  
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  
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  
Connecting audio ssource equipment  
Audio source equipment, such as a CD player, can be listened to through  
the 540R.  
There are three ways in which video connections to the 540R can be  
made (only one video connection should be made):  
Connections are made as audio connections explained in the previous  
column.  
Component - Connect video source equipment’s Component sockets to  
the corresponding sockets on the rear of your 540R using Component  
cable (3RCA-3RCA)  
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.  
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.  
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.
