Check if your VIBE-speaker is already prepared for use with the new AVM-amplifier modules: ONLY the Mk2-serie is adapted for use with the AVM-amplifiers!If you have an older cabinet, installation is quite complicated and should only be considered if you are a well skilled person for the job. If your VIBE-speaker cabinet is prepared for easy installation of the AVM-modules than please proceed with the installation as described below: A. Unplug the passive VIBE-cabinet from the amplifier and unscrew the screws that keep the metal connector plate in place. Keep the screws for later and remove the connector plate: on the back you will notice a special connector. To disconnect the special connector, press the connector lock and separate the two connectors. The amplifier module uses the same connector as the original connector plate: press the lock and join the 2 connector parts together. Make sure the lock function is on: you should hear a "click". Put the amplifier module in place and use the original screws to fasten the module. [. . . ] Always set the master level to zero when you switch the cabinet on, after this turn up the volume to the desired level. IMPORTANT: be aware that the power of the AVM-modules often exceeds the max. This means that you must be very careful and always start with the master level (8) or trimmer (9) almost closed, than increase the level step by step. [. . . ]
