Multi-Channel AV System
For Stereo System connection, see next section.
Connections
Standard Connection is via the Line level RCA phono Inputs. For a typical AV system set-up you will
need a single RCA phono interconnect. As this cable is likely to be quite long, make sure you get a
good quality fully screened cable. Your Q Acoustics dealer will be happy to supply you with a suitable
interconnect.
Connect the SUBWOOFER OUTPUT on the AV amplifier to the L/Mono Line input on the subwoofer,
pushing the plugs firmly home to ensure a good contact.
Setting Up
Check that all system connections are properly and securely made. Ensure that the subwoofer is
switched off.
Set the controls to the following default settings:
Level Approximately half
Crossover Fully clockwise (AV setting)
Phase invert 0°
Auto on AUTO or ON
Plug the supplied power cord into the subwoofer and then into the AC supply socket. Switch on the
power at the supply socket and then switch the power switch on the subwoofer to ‘ON’. The POWER
light on the subwoofer amplifier panel will glow and the subwoofer is operational.
Check the settings on your AV amplifier to make sure that the sub-woofer is set to ‘ON ‘or YES. The
subwoofer level on the AV amplifier should be set at its default position or 0dB. You should already
have set the speaker sizes and positions for all the other speakers in your system. If you have the
option to set the crossover frequency on the other channels make sure this is set appropriately to
your speakers. Set the distance (or delay) setting that is correct for the subwoofer position you have
chosen.
Play some stereo music you are familiar with and experiment with the Phase invert setting and level
control until you hear a seamless blend between the front speakers and the subwoofer. If you can
hear the subwoofer standing out it’s too loud!
Always bear in mind that the human ear sensitivity to bass varies enormously with the volume level,
hence the need for a wide range of programme material and sound levels.
