INTRODUCTION  
The WH-S8 & WH-S10 is the latest in a long line of distinguished Wharfedale active subwoofers. These technologically advanced  
subwoofers will complement the finest electronics and decor.  
Please read these instructions carefully before installing your subwoofers. A few minutes studying this manual will ensure superb  
performance from your subwoofer for many years.  
INSTALLATION  
Unpacking  
Carefully unpack each subwoofer.  
Retain all the packing materials so that your subwoofer can be repacked and shipped without damage.  
If you dispose of the packing, do so with regard to all recycling provisions in your area.  
Power Connection  
This subwoofer is set to operate for the mains voltage marked on the amplifier panel. Before connecting check that this  
voltage is correct for your mains supply.  
230 volt products - 220 volts to 240 volts  
115 volt products - 100 volts to 120 volts  
If you move to an area with a different mains supply voltage, please consult your Wharfedale dealer to arrange the conversion of  
this product.  
Positioning the Subwoofer  
Although the unit may be placed almost anywhere in the room, we recommend that it be placed in front of the listener and  
as central to the listening position as possible. There should be a mains outlet within easy reach. The subwoofer should not be  
operated within 450mm of a television set as the drive unit magnet may distort the picture. Remember that there should be a  
line of sight between the listening position and the front of the subwoofer otherwise the handset remote functions will not be  
operable.  
We suggest you initially position the subwoofer about 20cm (8 inches) from the wall. Placing the unit close to the wall will  
enhance the bass; placing it across the corner of the room will increase the bass further, possibly at the expense of clarity. Do not  
place the subwoofer close to surfaces or objects that may rattle. The floor under the subwoofer should be sound with no loose  
floorboards, etc. Experiment with locations and sources before making a final decision.  
Multi-Channel Room Placement  
The diagram shows the Dolby Labs recommended positions  
for multi-channel operation. For 5.1 channel operation use  
the satellites in the front and surround positions with the  
Subwoofer in the LFE position.  
If you have a 7.1 channel processor/amplifier you can  
enhance the system further by buying one of the larger  
loudspeakers from the Wharfedale range to use as front  
channel speakers and use the satellite units as back  
channels.  
If you have any queries, your wharfedale dealer will be  
pleased to advise you.  
 
USER INSTRUCTIONS: WH-S8 & WH-S10 SUBWOOFER  
Before Connecting the Subwoofer  
Level the subwoofer taking care to make sure it sits squarely on all its spikes.  
Switch off you amplifier and all connected source units at the mains.  
Unplug the power cords to all system components if necessary.  
Make sure the subwoofer is disconnected from the mains and that the ON/OFF switch is OFF.  
Before re-connecting your system to the AC power supply, check that all the connections are properly made.  
Check that all speaker terminals are done up tightly.  
Ensure that there are no strands of wire shorting adjacent speaker terminals.  
Signal cables should be properly terminated and fully screened to minimise hum. If you connect your subwoofer via low  
level signals inputs, the cable between your control unit or processor and the subwoofer could be quite long so screening is  
particularly important. Consult your dealer if in doubt.

A/V Processor Connections  
Your subwoofer has been designed for optimum performance  
with a digital processor. If your A/V processor has a line level or  
LFE subwoofer output you should use this connection. You will  
need to purchase a single screened RCA phono lead from your  
dealer. Connect this lead to the LFE input of the subwoofer as  
shown.

Alternatively, you may use a split mono lead from the

If you use a stereo pre and power amplifier, or an amplifier  
where the pre and main amplifier cab be separated, connect  
the subwoofer as shown. There are two alternative methods.

You will need two screened RCA ‘Y’ adaptors and two single

Remove the Pre-Main links on your amplifier. Connect the  
socket (common) of an RCA ‘Y’ adaptor to the Left Channel  
Pre Out socket on the amplifier and the other leg to the Left  
Channel Main In socket. Connect the remaining plug on this  
combination to the Left Channel Line Level input on the  
subwoofer. Repeat this for the Right Channel.

OUTPUT  
You will need two stereo (or four single) screened RCA cables.  
Connect a stereo cable from the Line Level Inputs of the  
subwoofer to the Output sockets of the pre-amplifier. Now  
connect a second stereo cable from the Line Level (High pass)  
Outputs of subwoofer to input sockets of the power amplifier.  
Make sure that the Right and Left Channels are not mixed  
up! The built-in high pass filter will roll off the low frequency  
output to the power amplifier and subsequently the main  
speakers.

OPERATING YOUR SUBWOOFER  
Check that all connections to the subwoofer have been properly made and that the main volume control is at minimum. Plug the  
supplied power cord into the mains socket on the rear panel.  
Initial Settings  
Volume Control: Set the subwoofer volume control to the minimum before proceeding.  
Crossover Control: Adjust frequency to integrate WH-S8 or WH-S10 subwoofer with your system requirement.  
Phase Switch: The Phase switch should be initially set to 0°.  
Switching On  
Plug in the mains plug and switch the power on. Now switch the subwoofer on with the rest of your system.  
When switched on, the power indicator light will glow and the subwoofer will be operational.  
Basic Tuning  
Volume Setting: Play a programme with extended bass and set the system volume to a resonal level. Adjust the subwoofer  
volume control to produce the desired level of bass. The bass should be even and an extension of the main loudspeakers. Do not  
set the control too high or you will swamp the sound with too much bass and clarity and definition will suffer.  
Phase Switch: If the bass is indistinct or lacks depth, the Phase switch may need adjustment. Set the switch to 0°and listen  
carefully to some music with extended bass. If there is insufficient bass output from the subwoofer set the Phase switch to 180°.  
Select the position which produces the most natural, extended bass.  
Crossover Adjustment: This adjusts the blend between the subwoofer and the main speakers and enables the system to be set  
up for optimum bass performance. The higher settings are for use with small bookshelf loudspeakers, the lower setting for large  
floorstanding models. If you choose too low a setting with small speakers, there will be a ‘hole’ in the bass response; too high a  
setting with large speakers will result in the upper bass becoming bloated. Again the subwoofer should be an extension of the  
main loudspeakers.  
Auto-Power Switch: This feature reduces the power consumption when there is no music signal. When the Auto-Power Switch is  
on, the amplifier will be activated immediately once an audio signal is detected at the inputs, and it will turn into the mute status  
when no signal is detected for about 20 minutes, which lowers the power consumption. This feature can be made invalid by  
setting this switch to off.  
Mains Operation  
When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from switching noises  
caused by domestic appliances, etc. The best practice is to switch the complete system on and off from a central point. Bear in  
mind that if you play the system with the subwoofer switched off you will get no bass!  
Always turn the main volume control to minimum when you switch the system on or off.  
 
USER INSTRUCTIONS: WH-S8 & WH-S10 SUBWOOFER

USER INSTRUCTIONS: WH-S8 & WH-S10 SUBWOOFER  
Subwoofer Maintenance  
Subwoofer should only ever be cleaned with a soft dry cloth to remove fingermarks, etc.  
Never touch subwoofer drive units as they can be damaged by improper handling.  
Never use a vacuum cleaner to clean a subwoofer grille. Brush it carefully by hand with a soft brush.  
When cleaning the floor under a subwoofer, switch it off, unplug it from the mains supply then lift it clear of the floor and move it  
to another location. Replace the subwoofer after cleaning.  
SERVICING
