Connecting to a Digital AV Processor
Stereo Line Level Connections
Connect a stereo RCA phono cable from the line
output of the preamp to the Subwoofer line inputs.
If your AV processor has a line level or LFE subwoofer output you should use this connection. You will need to
purchase a single screened RCA phono lead from your dealer. Connect this lead to the Left line input of the Subwoofer
as shown below.
Stereo line level connections will be necessary:
where there is no dedicated single subwoofer output, but where there is either a stereo subwoofer line output or a
separate preamp output.
where there is a preamplifier line output, or if an integrated amplifier, a pre/main link that can be separated.
The output must be controlled by the system volume control - a tape output is not suitable. If you are in doubt, consult
your dealer.

Delay and LFE Settings
Expanding the System
The purpose of delay is to enable surround and dialogue information to arrive at the listener’s ears at the same time
as the Front channels, even when the listening seat is in a non-ideal position.
If the listening position is equidistant from the Front and Rear speakers, a low delay setting should be set.
The closer the listener is to the Rear speakers the higher should be the delay setting used,
If the Centre speaker is level with (or slightly behind) the Front speakers, set the delay to zero. If the
Centre speaker is forward of the Front speakers, increase the delay.
In domestic systems the LFE channel typically feeds into the subwoofer. Where no subwoofer is used, the LFE
signal is combined with Front Channel information. When you set the LFE level at your AV processor, use care as the
powerful low frequencies can overload domestic loudspeakers.
If you hear popping or thumping noises coming from the front loudspeakers or subwoofer, immediately turn the AV
Processor's volume level down and then back off the LFE level. This should cure the problem. If it does not, back off
the volume level at the subwoofer (if you are using one) until the problem disappears.
Please read the relevant sections of your AV amplifier manual and familiarise yourself with the various issues. If you
are unsure, consult your dealer for help.
Dolby Labs, DTS and THX offer 6.1 and 7.1 formats which extend the 5.1 principle by adding one or two extra rear
effects channels. Although the precise configuration of these systems will depend on the capabilities of your
processor and you should be guided by those instructions, we would make some observations.
For most 6.1 and 7.1 formats the listening seat should not be too close to the rear wall.
Optimising the time delay so that information from all speakers arrives at the listening seat coherently is critical if the
benefits of these systems are to be fully realised. THX adjustments in particular need to be followed to the letter.
