SET UP
Once the input cables are connected and the controls are set in accordance with the initial set-up
procedure above, the subwoofer can be connected to the mains power supply and switched on
at the mains power switch.
• For use with an AV amp/ receiver (product with sub woofer output) run the auto set up on the
AV amp. Check the settings it has supplied and carry out fine adjustment if necessary. This
may include adjusting the gain or crossover frequency on the AV amp or level on the sub
woofer. The crossover frequency should be similar to that in the table on page 7.
Play some familiar movies to double check it integrates with the system and carry out any
adjustments to the levels or crossover frequency if necessary.
• For use with a stereo amp (product without Sub woofer output), set the crossover frequency
control in accordance with the table on page 7. The level may need to be adjusted so that
it integrates at all levels. Further fine-tuning of the crossover frequency may be required.
• The Phase Control can now be set, please refer to page 10 for further information. It is
important to try a variety of music and film excerpts with which you are familiar in order to
obtain the optimum overall settings.
TROUBLE SHOOTING
Should you experience any technical, or set-up problems with your subwoofer please check the
Trouble Shooting Guide below:
My subwoofer will not turn on/ no power.
• Is the LED illuminated on the unit? If not, then check your mains lead is properly connected
both at the subwoofer and at the mains outlet. Also check the fuse of the mains plug (where
fitted) and also the fuse in the subwoofer. See page 8 for further information on changing
the fuse and it’s location.
• Is the LED red? If so, you have power going to the unit. It could be that there is no signal.
• Is there a signal going to the subwoofer? If there is a signal present, is the Power Mode
Switch in the Auto or On position, and the source is turned on? Try adjusting the volume
level of the source and try the switch in the ‘On’ position.
If it still does not turn on/ power up, please contact your local dealer/ distributor or Monitor Audio
immediately.
No sound from subwoofer.
• Is the LED red or green? If it is red, then the unit hasn’t actually turned on, see suggestions
above. If it is green, then your unit is powered up and turned on. Check further suggestions
below.
• Are the signal leads connected correctly? Check these. If possible, check with a second,
known to be working set.
• Is the volume level just very low?
If it still does not output a signal, please contact your local dealer/ distributor or Monitor Audio
immediately.
