Placement: The Front and
Centre speakers should be
in line. If this is not possible,
consult your processor
manual for guidance
adjusting relative centre /
front delay times. If you have
a 5.1 system, the listening
seat can be closer to the rear
wall. As always, be prepared
to experiment.
Bass Management:
AV processors offer
choice of 'Large' or 'Small'
for the speakers. If you
choose 'Large' the speaker
receives the full frequency.
Choose 'Small' and the bass
is sent to the Subwoofer. We
recommend you
'Small' for bookshelf speakers
wherever they are used in the
system. The floorstanding
should be set to 'Large'. The
subwoofer option should be
enabled (set to 'ON' or 'YES')
Levels: When the basic system parameters have been established, put your processor into the
'setup' routine. Set up each individual speaker so that the level is the same at the listening position
as all the others. If your processor enables you to adjust the delay times, follow the instructions
closely as this will profoundly affect the final result. When you play a movie you may think the rear
channels are too soft - they aren't! You may however have to adjust the subwoofer level both at
the processor and at the subwoofer. Once set, do not re-adjust these levels.
LFE: The LFE channel sends all the bass sound effects to the subwoofer. If speakers are set to
'Small' , system bass from those channels is also sent to the subwoofer. If you play the system at
extreme levels and / or have the subwoofer level set too high you may overdrive the subwoofer
with unpleasant sonic results. If this occurs, reduce the level immediately.
Phase: If your speakers are incorrectly wired the bass will be blurred and thin. In this case, check
the wiring carefully. If your speaker wire has a tracer along one core, consistently use the striped
core to connect all the positive (RED) terminals. In this way the system will always be in phase.
Always follow the instructions in your AV processor manual!
