REAR PANEL CONNECTIONS
Open the carton and remove all the top packing pieces. Lift the
subwoofer out taking care not to damage the cabinet. When lifting the
unit from the carton support it from the bottom. DO NOT attempt to lift
the subwoofer out of the carton using the polythene bag. The unit is
heavy; if you cannot manage it easily, get someone to assist you.
After removing the subwoofer from the carton, remove the plastic bag.
Retain the packing materials for future use or return them to your dealer.
If you decide not to keep the packing, please dispose of it having regard
to any recycling regulations in your area.
Please retain the user manual and the purchase receipt for future
reference. If you transfer this equipment to a third party, please ensure all
the instructions are passed on with the product.
CHANGING THE SUBWOOFER FEET
The subwoofer is fitted with rubber feet. A set of spikes is also provided.
Fitting Spikes
Invert the subwoofer. Protect the top by placing it on a soft surface such
as a towel. Loosen each threaded washer and unscrew the rubber feet.
Remove the threaded washers and replace them on the spikes. Screw a
spike part-way into each hole and hand-tighten the washer. When all
four feet have been fitted, stand the subwoofer upright.
CONNECTING THE SUBWOOFER
Note: When using spiked feet take care not to drag the subwoofer and be
careful not to pierce objects or cables which may be hidden under
carpets, etc. Spikes are not suitable for use with stone floors and can

Stereo Line Level Connections
Stereo line level connections will be necessary where there is no
dedicated single subwoofer output, but where there is either :
!
A stereo subwoofer line output or a separate preamp output.
!
In stereo systems where there is a suitable preamplifier line output,
or if an integrated amplifier, a pre/main link that can be separated.
The output must be controlled by the system volume control - a tape
output is not suitable. If you are in doubt, consult your dealer.
Stereo Connections: Connect a stereo RCA phono cable from the line
output of the preamp to the Subwoofer line inputs.
Power Connections
Before connecting your subwoofer check that the check that mains
voltage marked on the amplifier panel is correct for your mains supply.
!
230 volt products - 220 volts to 240 volts
!
115 volt products - 110 volts to 120 volts
If your AV 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 Left line input of the
Subwoofer as shown below.
Positioning the subwoofer
The RS-10 subwoofer uses a rear-firing bass driver. For the unit to
perform at its best it should be placed with the heatsink fins 10 mm away
from a wall. The bass driver will now be 50mm from the wall.
The rear wall should be smooth, solid and free from vibration. The floor
under the subwoofer should be firm and free from rattles.
Caution: Do not place the subwoofer touching the wall. There must be air
circulation around the unit and the mains switch should be accessible at
all times.
Although the unit may be sited by either the rear or side walls, we
recommend that is placed in front of the listener central to the listening
position. To avoid excessive booming and coloration we suggest that
you operate the subwoofer at least 500mm away from corners.
There should be a line of sight between the listener and the front of the
subwoofer otherwise the remote functions will not be operable.
