540R AV receiver

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.

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

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

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.

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.

EXPERIMENT !!

REMEMBER - IF IT SOUNDS RIGHT TO YOU, IT IS RIGHT !!

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.
