640R setup

The setup of the 640R is a 5 stage process as follows:

1.Speaker configuration.

2.Speaker delay

3.Level calibration

4.Source setup (2 settings)

-Source audio type

-Source video type

5.Assigning any HDMI sources

1. Speaker configuration

First decide what kind of speaker package you would like to use. The options are 5.1, 6.1 or 7.1. The 640R can support up to a 7.1 speaker setup which means 7 speakers (Front Left, Front Right, Centre, Surround Left, Surround Right, Surround Back Left, Back Right) plus a mains powered Subwoofer (the .1).

Refer to the diagrams below for typical examples of 5.1, 6.1 and 7.1 loudspeaker setups. Always adjust the speaker and listening positions until you are happy with the sound. Please refer to the loudspeaker and subwoofer manuals for more detailed positioning information.

1Front Left and Right speakers

For stereo and multi-channel sound.

2Centre speaker

For dialogue and centre sounds. Ideally position at a similar height to the front left and right speakers (above or below the TV/monitor). Using a centre speaker from the same manufacturer/range as used for the front left and right speakers is advisable. This “timbre matching” allows surround effects to flow more naturally from left to right without obvious transitions between the speakers.

3Surround Left and Right speakers

For ambient and multi-channel sound. Floorstanding speakers should be angled towards the listening position. Bookshelf/standmount speakers should be wall mounted or used with dedicated speaker stands, positioned at or above ear height.

4Subwoofer

For improving the bass in your system, as well as reproducing dedicated LFE cinema effects when playing Dolby Digital or DTS encoded discs. Your subwoofer can often be placed almost anywhere in the room as bass is less directional, but experimentation with positioning is recommended.

5Surround Back Centre speaker

Sixth channel speaker required for enjoying Dolby® Digital EX or DTS®-ES or other 6.1 audio. Improves the quality of sound effects by filling the gap between the surround left and rear right speakers. Position the speaker firing towards the front of the room.

6Surround Back Left and Right speakers

Individual back speakers in place of a single surround back. Used with the very latest 7.1 processing types. Remember to experiment with the positions until you are happy with the sound.

In each case the 5.1/6.1/7.1 in fact relates to the maximum number of speakers that can be used, as for each the Centre, Sub and Surround speakers can all be deleted if required (although of course performance is reduced). For example, if you choose not to use a Centre Channel speaker you can set this to 'None' in the settings as shown later and the 640R will automatically redirect the centre channel audio information into the Left and Right Front channels, creating what is known as a 'Phantom Centre'.

Similarly, you might decide not to use a subwoofer if your main Left and Right speakers are capable of reproducing enough bass for a satisfying music/movie experience. The 640R will then automatically re-direct the bass from the Subwoofer/Low Frequency Effect channel to the Left and Right Front Speakers.

Note: This setup is very important as the 640R will also automatically use this information to select appropriate Dolby and DTS decoding modes dependant not only on the source material but also the speaker package it knows you have.

First tell the unit the type of package you have. This is done via the On- Screen Display. Highlight the ‘Speaker Configuration’ menu by using volume up and down on the remote then go to it by pressing Enter:
