Set the subwoofer power switch to OFF.
Turn the system Volume Control to minimum.
Connect the supplied power lead to the IEC power socket on the subwoofer and connect the mains plug into the wall socket.
Set the subwoofer volume control midway (12 o'clock)
Switch on the mains power.
Fine Tuning Your Subwoofer
Switch on the subwoofer power switch. Check that the power indicator on the amplifier panel 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.
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
LOW PASS (CROSSOVER) FILTER: 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 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.
AUTOPOWER SWITCH- MS-CUBE; MS-8; MS-DUO
In normal mode the subwoofer is permanently on. This may result in low level hum or noise if the rest of the system is switched off and the subwoofer is left switched on. Setting the AUTO switch to ON automatically turns the subwoofer on when a signal is detected at any of the inputs and turns it off (Standby Mode) after a period of inactivity. We recommend 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 and GREEN when operational. If your subwoofer is disconnected from the mains or the Power switch is “Off”, the indicator will be extinguished.

Preliminaries
Open the carton and remove all the top packing pieces. Lift the subwoofer out carefully. DO NOT lift the subwoofer out of the carton using the protective bag. The unit is heavy; if you cannot manage it easily, get assistance.
Retain the packing materials. 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. If you transfer this equipment to a third party, please ensure all the instructions are passed on with the product.
Attaching Spikes
Carefully invert the subwoofer. Protect the top surface from scratches or damage when the subwoofer is inverted.
The subwoofer has four spikes. Prepare the spikes as shown and screw one spike into the threads on the base of teach subwoofer foot. Set the subwoofer upright taking care not to cause damage.
Adjust the spikes in and out until the subwoofer is firm and level. Use a spirit level to assist you.
Now tighten the nuts securely.
When moving speakers, do not let the spikes pierce objects which may be concealed under a carpet.
Never drag loudspeakers. If you cannot lift them easily, get someone to assist.
Power Connections
The subwoofer is factory set to operate from the mains voltage marked on the amplifier panel. Before connecting check this voltage is correct for your mains supply.
230 volt products - 220 V to 240 V
115 volt products - 110 Vs to 120 V
If you move to an area with a different mains supply, consult your dealer for advice.
*DO NOT change the operating voltage of this product without seeking expert advice first.
When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from switching noises.
LOUDSPEAKER SIZES: Many digital AV processors require you to specify the size of speakers in the various channels. These are usually ‘Large’ or ‘Small’. We recommend that you set the centre and surround speakers to 'Small'. This will direct all the bass in the system to the subwoofer and provide clean, deep and louder bass. Set the ‘Subwoofer’ option on the processor to 'On’ or 'Yes'.

Set large floorstanding loudspeakers to ‘large’. Smaller floorstanding |

| 45Hz | 75Hz | |
loudspeakers may be optionally set to ‘small’. In this case the subwoofer |
| 35Hz | 85Hz |
crossover setting should be 55Hz. If you find the bass excessive, set the |

loudspeaker to ‘large’. |

Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode. Adjust the levels until all channels are equally loud. You may need to adjust the subwoofer output level. Avoid setting too high a level which 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: 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 as the LFE channel may contain powerful low frequencies which 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.
