Operation; Handling - Conrad Boom 80 MkII Notice D'emploi

10. Operation

After installing and checking all the necessary cable connections you can set the subwoofer into operation.
• If you have checked the cable connections, reconnect the negative terminal of the battery.
• Turn the volume control LEVEL (4) counter-clockwise to minimum.
• Put the FREQ (1) controller roughly to the middle position.
• Put the PHASE (3) controller to the 0° position.
• Switch on your car radio. The indicator POWER display (2) lights up.
If the POWER display (2) does not light up, an error has occurred. The amplifier has to be switched off immediately.
In such a case, check all connections and the speakers. If you cannot detect an error, please contact a specialist
for help.
• If the POWER display lights up (2), set the car radio's volume to a medium volume level.
• Now adjust the subwoofer volume to the volume of the other speakers using the LEVEL (4) control.
The subwoofer should not drone or be able to be heard separately. It should merely support the additional speakers
in the deep-bass range.
• You may now also adjust the set separating frequency with the controller FREQ (1) to achieve the best sound.
Again, observe a clean bass playback that will seamlessly fit into the acoustic pattern of the other speakers.
• Also try out different settings of the PHASE (3) controller. A changed phase shift often leads to better bass playback
(depending of the installation suite of the subwoofer).

11. Handling

• If the volume inside your car is too high, you will not hear acoustic warning signals. This constitutes a danger to
yourself and other road users. Therefore, make sure the volume is at a suitable level.
• Inattentiveness on the road could lead to serious accidents. Operation of the hi-fi system may therefore only take
place if the traffic situation permits and you are not unduly distracted by operating the system.
• Do not keep any magnetic storage media such as computer disks, video cassettes or similar near the subwoofer
as the magnetic field of the speaker may corrupt the information stored on these media.
• Do not listen to excessively loud music for long periods of time. This could damage your hearing.
