Prescribed use
The Built-in Amplifier Module Active serves to amplify audio signals of audio systems
and to convert these signals into audible sound waves by means of a subwoofer
chassis that can be connected externally.
Ensure to connect the inputs only to low-level audio outputs or to loudspeaker out-
puts of audio systems.
Ensure to connect the loudspeaker output only to a suitable subwoofer chassis.
Ensure to connect the power supply connector only to 230V~/50Hz (10/16A) alter-
nating voltage.
Ensure to use the device only indoors, not outdoors. Contact with humidity, e.g. in
the bathroom or in other humid rooms, must absolutely be avoided.
Any use different to the one described above damages the built-in amplifier module.
Moreover, this involves dangers, e.g. short-circuit, fire, etc.
No part of the product may be modified or rebuilt. Do not open the housing!
Always observe the safety instructions.
