Wharfedale PowerCube 12 plus, PowerCube 10 plus, PowerCube 8 plus Owners manual
THE HOME THEATRE ENVIRONMENT CONNECTING TWO SUBWOOFERS
FRONT, CENTRE AND REAR CHANNELS
The front channel loudspeakers should be placed on either side of the television screen, 2 to 3
metres apart. and rotated slightly towards the listeners.
As the Centre speaker carries the dialogue effects, it should be placed central to the listening
position and close to the TV screen. Operating height is important. Ideally, the front and
centre channel speakers should be operated at the same height and with the tweeters at ear
level to a seated listener.
Place the Rear speakers 2.5 - 3.5 metres apart in a high position behind the listener. If you
are using dipole or special surround speakers follow the instructions for those units.
SUBWOOFER
As the ear is unable to detect the direction from which deep bass originates, this allows
freedom in positioning the subwoofer. Varying the distance from the wall will alter the
amount of bass. Some prefer to place the subwoofer against a corner of the room. This
arrangement gives more bass at the possible expense of clarity.
LOUDSPEAKER SIZES
Many digital AV Processors require you to specify the size of speakers in the various channels.
These are usually ‘Large’ or ‘Small’. Unless your loudspeakers are large floor standing units,
you should choose 'Small' for the Front channels, as the subwoofer is going to be better at
providing clean, deep and louder bass. Choose 'Small' for the surround channels and also for
the Centre channel, so that any bass from these channels will be directed to the subwoofer.
Set the ‘Subwoofer’ option on the processor to 'On’ or 'Yes'.
SETTING LEVELS
Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode
(see instructions supplied with your processor.) Adjust the levels until all channels are
reproduced at equal loudness.
You may need to adjust the subwoofer output level. Avoid setting too high a level or you will
swamp the sound with bass which be tiring to listen to and may limit the subwoofer’s ability
to respond to large bass transients. Set a sensible level going into the subwoofer. The
subwoofer volume control should be between 12 o’clock and 3 o’clock .
LFE
The Low Frequency Effects channel was designed as an additional bass channel with its own
dedicated subwoofer. In practice however, if all the speakers are set to Small, the LFE channel
will be combined with the bass from other channels and all this feeds into the subwoofer. When
you set the LFE level from your AV processor, use care with this setting as the LFE channel may
contain powerful low frequencies which, although normal in a cinema, may overload a
domestic subwoofer.
If, during a programme, you hear popping or thumping noises coming from the subwoofer,
immediately turn the AV Processor's volume level down and then back off the LFE level. If this
does not cure the problem, back off the volume level at the subwoofer.
Please read the relevant sections of your AV amplifier manual and familiarise yourself with
the various issues. If you are unsure, consult your dealer for help.
CARE AND MAINTENANCE
The loudspeaker cabinets can be cleaned with a damp cloth or with a spray furniture polish
and a soft cloth. Apply the spray sparingly to the cloth and then polish the cabinet. Never
apply spray directly to the cabinet.

ESSENTIAL INFORMATION FOR UK USERS
The power cord on your Wharfedale powered subwoofer may be supplied with a plug incorporating a fuse, the value of
which is indicated on the pin face of the plug. Should the fuse need to be replaced, an ASTA or BSI approved BS1362 fuse
must be used of the same rating. If the plug is cut off it must NOT be
re-used. Dispose of any such plug safely. There is a danger of electric
shock if a cut-off plug is inserted into a mains socket.
The wires in the mains lead are coloured in accordance with the
following code:
Green and Yellow - Earth: Blue - Neutral: Brown - Live.
As the colours of the wires in the mains lead may not correspond
with the markings identifying the terminals in the replacement
mains plug, proceed as follows:
The wire coloured Blue must be connected to the terminal marked
with the letter "N" or coloured Black. The wire coloured Brown must
be connected to the terminal marked with the letter "L" or coloured
Red. The wire coloured Green and Yellow must be connected to the
terminal marked with the letter ‘E’,or coloured Green, or Green and
Yellow, or marked with the Earth symbol
NEVER remove any parts or components and refer all servicing to qualified personnel. This
product contains no user serviceable parts.
DO NOT connect the mains power to any signal input terminal on the sub-woofer Control Panel
DO NOT change any connections to the sub-woofer or your system without first switching off
the power to all the components in your AV system
DO NOT use your amplifier at its maximum volume setting. The resulting distortion may
damage your loudspeakers and sub-woofer. The position of the Volume Control on your
amplifier is NOT a reliable guide as to ‘how loud’ your equipment will play. Allow your
amplifier some
“headroom” so it can operate without stress.
DO turn down the volume control on your amplifier or receiver before turning the equipment on
or off. This will protect your sub-woofer against switching 'thumps' and other spurious signals.
Make sure that adequate clearance (at least 450mm) exists between the sub-woofer and the
TV otherwise the powerful drive-unit magnets may interfere with the colours on the screen. If
this occurs, switch the TV set off. After 15 minutes switch on the TV set. The internal circuits of
the TV set should now restore normal colour balance.

SPEAKER LEVEL CONNECTIONS
The high level Speaker connections should be used only if your amplifier does not have a line
level subwoofer output. In this connection the subwoofer is fed together with the Front
loudspeakers. For this you will need two extra twin core cables.
Choose a good quality audio speaker cable of reasonable size. Avoid using cheap ‘bell’ or
‘zip’ cables. Audio speaker cable has a polarity stripe or rib along one conductor to simplify
connecting your speakers.
Split the cable at each end to a depth of
30mm. Strip about 7mm of insulation from
7mm
each end and lightly twist to gather the wire
strands.
30mm
The Speaker Level connectors are screw
terminals located on the control panel.
Unscrew a terminal and insert the cable into
the hole at the base. Re-tighten the terminal
securely. Make sure that the terminal grips
the bare wire and there are no loose strands which could touch adjacent terminals.
There are two methods of connecting the subwoofer.
A: Ensure the Front loudspeakers are correctly connected.
Using one of the additional twin core cables, connect the Left Speaker Terminals on the sub bass
unit to the Front Left speaker terminals on the amplifier. Connect the Red (+) speaker terminal
on the amplifier to the Red (+) terminal on the subwoofer. Connect the Black (-) speaker
terminal on the amplifier to the Black (-) terminal on the subwoofer. Now connect the Right
Speaker terminals on the subwoofer to the Front Right speaker terminals on the amplifier.

OPERATION
POSITIONING THE UNIT
Although the unit may be placed almost anywhere in the room, even behind the sofa or the
TV set, we recommend that it be placed in front of the listener and as central to the listening
position as possible. The subwoofer should not be operated within 450mm of a television set
as the drive unit magnet may distort the picture.
We suggest you 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. Experiment with a variety of locations and
sources before making a final decision.
As the subwoofer is a powered unit there should be a mains outlet within easy reach.
The bass ports are mounted at the rear of the subwoofer and should not be obstructed by
placing the unit against soft furnishings. 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.
SETTING UP
Set the subwoofer power switch to OFF. Turn the system Volume Control to minimum. Recheck all system connections. Connect the supplied subwoofer power lead to the IEC power
socket on the subwoofer and connect the mains plug into the into the wall socket. Switch on
the mains power. Set the subwoofer volume control to the mid position (12o'clock) before
proceeding.
VARIABLE CROSSOVER This control should initially be set to 85 Hz when the subwoofer is used
with small bookshelf speakers and to 65 Hz when used with large floor standing speakers.
PHASE SWITCH: The Phase switch should be initially set to 0°.
AUTO SWITCH: the Auto switch should be initially set to OFF.
FINE TUNING
Switch on the subwoofer power switch and check that the power indicator on the front of the
cabinet glows. Now switch on the system. Play a programme with extended bass and set the
system volume to a reasonable level. Adjust the subwoofer volume control to produce the
desired level of bass. Do not overdo things!
PHASE SWITCH: If the bass is indistinct or lacks depth, the Phase switch may need
adjustment. Set the switch to 0º and listen carefully to some music with extended bass. If
there is insufficient bass output from the sub-woofer set the Phase switch to 180º. 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 settings 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.
AUTO SWITCH. In normal mode the subwoofer is permanently on. This may result in low level
hum or noise from the subwoofer if the rest of the system is switched off and the subwoofer is
left switched on.
when a signal is detected at any of the inputs and turn it off (Standby Mode) after a period of
inactivity. We recommend that the AUTO switch be set to ON for normal operation.
In AUTO mode the indicator on the front of the subwoofer will glow RED when the unit is in
Standby mode and GREEN when operational. If your subwoofer is disconnected from the
mains power, or the Power switch is “Off”, the indicator will be extinguished.
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. 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.
Setting the AUTO switch to ON will automatically turn the subwoofer on
