Operation - Q Acoustics 3000 Series Q3070S User Manual

Operation

Setting Up and Use
Auto On: This feature enables you to switch the main system on and off without having to remember
to switch the subwoofer on and off as well.
If there is no signal input, after a few minutes the subwoofer will automatically power down into
Standby mode. This is indicated by the POWER light on the rear panel changing to red. As soon as
the subwoofer senses an input it will automatically switch into operational mode and the power light
will again glow green. Some types of music and some TV channels have very little low frequency
information in the audio signal in which case the subwoofer may not automatically switch out of
standby even though sound is coming from the other speakers in the system. If this happens then
the Auto On switch can be switched to ON making the sub-woofer stay on at all times.
Although the subwoofer can be safely left in standby mode indefinitely, if you are going to be absent
from home for a long period we advise that the unit is switched off at the Power Switch.
The 3070S Subwoofer also has a fail safe heat protection system. If the amplifier overheats it will shut
down momentarily and then resume operation. If this occurs check that the ventilation holes on the
control panel are not covered and that the subwoofer is not placed too close to a source of heat such
as a radiator.
