340R setup

The setup of the 340R 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 video sources

1. Speaker configuration

See below for a typical 5.1 Speaker configuration. Five (5) main speakers are used plus a Subwoofer (the .1) for bass:

11

4 5.1

33

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.

The 5.1 relates to the maximum number of speakers that can be used, as 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 340R 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 340R will then automatically re-direct the bass from the Subwoofer/Low Frequency Effect channel to the Left and Right Front Speakers.

To setup your speaker configuration, press the OSD button on the remote to activate the On-Screen Display (OSD). Note: You must be connected to a TV/Monitor by Composite or S-Video connections first. Highlight the ‘Speaker Configuration’ menu by using the Volume Up/Down buttons on the remote and press the Enter button:

	Quit : [OSD]	Ver1.1

Now move down and by highlighting each speaker in turn and using the Left and Right arrows select from ‘Large’, ‘Small’ or ‘None’ for each speaker:

Center	:Small
Surr. L/R	:Small
Subwoofer	:Yes

Return To Menu	: [OSD]

‘Large’ or ‘Small’ are used to describe each speaker in terms of bass response, they do not necessarily reflect the actual physical size of the speaker.

Large = Speakers with an extended low frequency response of approximately 20-40Hz to 16-20kHz (floorstanders or high quality larger stand-mounted speakers).

Small = Speakers with a less extended low frequency response of approximately 80-100Hz to 16-20kHz (small stand-mounted, bookshelf or satellite speakers).

Setting each speaker allows the 340R to perform what is called Bass Management and to direct low frequency bass from music and the Low Frequency Effects channel of surround sound material to those speakers best able to reproduce it. If you do not wish to use any of the speakers change it’s setting to ‘None’.

The Subwoofer output can also be set to ‘Yes’ or ‘No’. If no sub is being used make sure this setting is set to ‘No’ to allow the 340R to re-direct the bass information in this channel to other speakers.

Note: The 340R will force some speakers to certain settings in some of the following circumstances!

The Front Left and Right speakers may be ‘Large’ or ‘Small’ but never ‘None’ as they are always required for any type of music/movie reproduction.

Bass must always be reproduced by either the Front Left and Right or Subwoofer channel (or both). The 340R will thus not allow a combination of ‘Small’ front speakers and no subwoofer.

If the Front Left and Right cannot reproduce low frequency bass a Subwoofer must be used i.e. If the Front Left and Right are set as ‘Small’ the Sub must be Set to ‘Yes’.

Also, setting the Front Left and Right as ‘Small’ will always set the other speakers as ‘Small’ (and the Sub to ‘Yes’). This is because LFE/ bass information should not be redirected to the surround channels.

To store the setting simply come back out of the OSD (pressing the OSD button always moves back one menu item, and then exits and stores from the main menu screen).
