Centre<br />
The centre speaker allows for a more realistic<br />
reproduction of dialogue. The centre speaker<br />
should have a similar tonal balance to the front<br />
left and right speakers and be positioned at a<br />
similar height.<br />
Subwoofer<br />
A subwoofer will greatly improve the bass performance of<br />
your system. This is useful for reproducing special cinema<br />
effects, especially where a dedicated LFE (Low Frequency<br />
Effects) channel is available, as with many discs encoded<br />
with Dolby or DTS technologies.<br />
More than one subwoofer unit may be required for larger<br />
installations, particularly in rooms of a timber frame<br />
construction. Multiple subwoofers need care in placement<br />
because there may be cancellation effects between the<br />
units and you may require expert advice.<br />

Front left and right<br />
Position your front left and right speakers to<br />
achieve a good stereo image for normal musical<br />
reproduction as well as for the multichannel<br />
modes. If they are placed too close together there<br />
will be a lack of spaciousness; if they are placed<br />
too far apart a stereo image will appear to have a<br />
large ‘hole’ in the middle and will be presented in<br />
two halves. If there is no practical alternative to<br />
placing the speakers widely apart, this effect can<br />
be overcome in music reproduction by using the<br />
centre sound extraction from the left and right<br />
speakers (see Dolby Pro Logic II Music mode).<br />

Surround left and right<br />
The surround left and right speakers reproduce<br />
the ambient sound and effects present in a<br />
multichannel home cinema system and should be<br />
installed slightly higher than the listener’s ears.<br />
Surround back left and right<br />
The surround back left and right speakers<br />
are used to add extra depth and better<br />
sound localisation and should be installed<br />
approximately one metre higher than the<br />
listener’s ears. Place the two surround<br />
back speakers such that there is an arc of<br />
approximately 150 degrees between each<br />
surround back speaker and the centre speaker.<br />
The surround back speakers should face the front<br />
of the room as shown in the diagram to provide<br />
the largest ‘sweet spot’.<br />
Single surround back centre speaker<br />
It is also possible to use a single surround back<br />
speaker positioned centrally behind the listening<br />
position instead of two. In this case connect it to the<br />
SBL speaker output. Follow the instructions in the<br />
‘Spkr Types’ section of the Setup Menus for how to<br />
configure the <strong>AVR600</strong> for this setup.<br />
