Initial Settings
Volume Control: Set the subwoofer volume control to the mid position (12 o'clock) before proceeding.

Phase Switch: The Phase switch should be initially set to 0°.
Connect the red, positive (+) terminal of the Left loudspeaker to the corresponding red, positive (+) amplifier terminal. Connect the black, negative

The subwoofer ON/OFF switch has a rocker action; press “I” to switch the equipment on and “O” to switch it off. When switched on the light beside the power switch and the light on the front of the subwoofer 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 reasonable 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.

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. See the next section for further details.
Again the subwoofer should be an extension of the main loudspeakers.
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!

In AUTO mode, when the subwoofer is switched on, the subwoofer will become active. If there is no audio input present the subwoofer will go immediately into Standby. As soon as an audio input is detected the subwoofer will then switch on.
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.
Always turn the main volume control to minimum when you switch the system on or off.
