Vector VW-8 - Manual (Page 5)

Positioning/Initial Set Up
Leave the subwoofer unplugged from the mains until the installation procedure is completed. The
subwoofer should now be sited in the most suitable position, preferably not directly in the corner of the room as
this may cause excessive bass ‘boom’. Once a desirable position is achieved it is important to check if the cables
are long enough to reach comfortably without being under tension. The optimal control settings will depend
entirely on your system configuration. For initial trials set the controls as follows:
Volume Control Should be set to minimum
Frequency Control Should be set to the minimum position (45Hz)
Phase Control Should be set to zero degrees
Power Mode Switch Should be set to ‘Auto’
By Pass Filter Switch Should be set to the ‘On’ position
Input connections can be made at this stage before the power is connected to the subwoofer.
Never connect or disconnect any leads with the subwoofer switched on.
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.
Do not play any music at this stage. Power Mode Switch in the ‘Auto’ position, the unit should remain in standby
with the power LED around the Logo Badge on the front and on the amp panel should be red, until the AV amp
is turned on or a signal is received.
To manually set up you sub, play a variety of music/ film excerpts that you are familiar with starting at a very low
volume level, increasing to an average listening level once you are sure everything is working correctly. Please
now follow the instructions below: -
For use with an AV amp/receiver (product with Subwoofer output) please select the by pass filter switch to •
the ‘On’ position. Otherwise select by pass filter switch to the ‘Off’ position. This engages the crossover
frequency control on the subwoofer (please refer to pages 5).
If u • sing the crossover frequency control please adjust in accordance with the table on page 5. Further fine-
tuning may be required.
The Phase Control can now be set, please refer to pages 4 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.
A lot of AV amplifiers/ receivers have an auto set up on them. If you use this to set up your sub, please remember
to go back into the settings of your AV amp and check them. You may need to go back and manually fine tune,
both on the sub and on the AV amp to achieve optimum performance.

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.
• Are the LED’s (one on the amp panel and the other on the front illuminating the ‘M’ Logo) 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 5 for further information on changing the fuse and it’s location.
• Are the LED’s red? If so, you have power going to the unit. It could be that there is no signal.
• Has it got a signal going to it? If so, is the Power Mode Switch in the Auto or On position, and the signal
source is turned on? Try adjusting the volume level of the source.
If it still does not turn on/ power up, please contact your local dealer/ distributor or Monitor Audio immediately.
No sound from subwoofer.
• Are the LED’s 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.
