Multi-Channel AV System
Placement: The Front and
Centre speakers should be
in line. If this is not possible,
consult your processor manual
for guidance on 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 the choice
of 'Large' or 'Small' for the
speakers. If you choose 'Large'
the speaker receives the full
frequency. Choose
and the bass is sent to the
Subwoofer. We recommend
you choose 'Small' for the
3090C and the 3010 and 3020
wherever they are used in the
system. The 3050 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!
'Small'
Above is the Dolby Labs recommended layout for 7.1systems. The 6.1 layout is the
same except a single central speaker replaces the two back units. The 5.1 layout has
no back speakers
