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!
Always turn the main volume control to minimum when you switch the system on or off.
Volume Setting:
Play a programme with extended bass and set the system volume to a resonal 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.
Phase Switch:
If the bass is indistinct or lacks depth, the Phase switch may need adjustment. Set the switch to 0°and
listen carefully to some music with extended bass. If there is insufficient bass output from the subwoofer set the
Phase switch to 180°. 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 setting 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. Again the subwoofer should be an extension of the main loudspeakers.
Auto-Sense Switch:
This feature reduces the power consumption when there is no music signal. When the
Auto-Sense Switch is on, the amplifier will be activated immediately once an audio signal is detected at the inputs,
and it will turn into the mute status when no signal is detected for about 20 minutes, which lowers the power
consumption. This feature can be made invalid by setting this switch to off.
