About tthis AAV rreceiver

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

II (Pro Logic is a registered trademark of Dolby Laboratories), for

Logic 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 sevenchannel 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.

Cleaning use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

Grounding aand ppolaris 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 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.

Plug ffitting iinstructions ((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.

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.

Notes oon lloudspeaker pplacement

Front lleft aand rright lloudspeakers 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.

Centre cchannel LLoudspeakers loudspeaker needs to be positioned directly above or below your screen, facing the listening position.

Surround lleft aand rright LLoudspeakers 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

These should be placed

Ideally your centre channel

If you are using normal hi-fi

FM aantenna

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 lloop aantenna

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.
