Pre Out - Main In Connections
If you use a separate stereo pre and power amplifier, or an amplifier where the pre and main amplifier can be separated, connect the sub- woofer as shown. There are two alternative methods.
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

Remote Handset
All control functions are carried out using the remote handset.
Volume: Press the Volume + key to increase the volume level. Press the Volume - key to decrease the volume level of the subwoofer. The volume range on the front panel display varies from 00 (minimum) to 99 (maximum).
A:You will need two screened RCA ‘Y’ adaptors and two single RCA phono cables.

amplifier. Connect the Red (+) speaker terminal on the amplifier to the Red (+) terminal on the subwoofer. Connect the Black

Installing batteries
The handset operates on two LR6 (AA) batteries which are supplied The battery compartment is located at the rear of the handset. Unwrap the batteries and slide the cover off the handset. Place the batteries in the handset, the correct orientation is shown on the diagram. When the batteries are
installed, replace the cover.
Low Pass Filters: Pressing the appropriate filter key will select the frequency at which the subwoofer rolls off. The filter has steps at Off and

Phase: This key toggles the subwoofer between 0º and 180º phase shift.
Presets: Four different settings of level, frequency and phase can be stored. Pressing and holding any of the preset keys on the remote for 3 seconds will cause the current settings to be stored in that preset. The display will show the preset number then flash the preset number once to show it has stored the preset.
To change from one preset to another, press a preset key on the remote for less than 3 seconds to recall the settings of that preset. The display will show the preset number:

Switching on the Subwoofer
Check that all the connections to the subwoofer have been properly made and that the system volume control is at minimum. Plug the supplied power cord into the mains socket on the rear panel. Plug the mains plug into the wall socket and switch the power on. Now switch the subwoofer on with the rest of your system. The subwoofer on/off switch has a rocker action; press the upper part to switch the equipment on and the lower part to switch it off. When switched on the light above the power switch will glow and the subwoofer will be operational.
light will extinguish (as the setup no longer matches the preset).
Note: When brought out of standby for the first time, the unit will display the factory presets. Thereafter, bringing the unit out of standby will revert it to the operational state last used. If you switch the power on and off at the rear panel while the unit is in standby, the unit will power up to a normal operating state (i.e. not in standby). To enter standby, again press the Standby key.
SETTING UP YOUR SUBWOOFER
General Notes
Your subwoofer is most likely to be used with two typical programme sources, music and movies. The setup for these two very different sources may be different if best results are to be achieved. Please read these setup notes in conjunction with your processor and speaker manuals.
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 gauge. 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 25mm. Strip about 7mm of insulation from each end and lightly twist to gather the wire strands.
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.

When routing any cables to loudspeakers do not run them across open floor spaces where they may cause danger to people and pets. Route them safely, around room boundaries if necessary.
Operation - Controls and Functions
Control functions are carried out using the remote handset. To operate, the handset must be point at the subwoofer and be in direct line of sight.
Standby: The Standby key brings the subwoofer in and out of Standby.

In Standby mode all the lights on the subwoofer front panel are extinguished. The rear panel light remains on to show the unit is powered.
All setting up of the subwoofer should be performed with tone controls and filters set ‘flat’.
Listening Rooms and Subwoofer Positioning:
Listening rooms are not ideal. Most rooms are reverberant with some parallel walls. Because of room geometry and construction there will be areas with severe peaks at some frequencies and severe troughs at others. These peaks and troughs are called ‘standing waves’ and if you site loudspeakers in such areas the response will be highly
To help locate standing waves in your listening room, one idea is to sit in the listening seat and recruit a friend with a deep voice to speak as he moves around the area where you propose to site your subwoofer - you will soon find out where not to site it! Where the voice sounds most natural is a good place to start.
The low frequency response of the subwoofer and its blend with the main loudspeakers is greatly affected by positioning. Although bass is enhanced by walls or corners, so often is coloration. As the drive unit faces rearward, the wall will influence the sound. The wall should be smooth and solid and ideally,
