3/28 AVM-AMPLIFIER MODULES
INSTALLATION AND CONNECTIONS
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. The installation inside older cabinets is not explained!
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.
B. Keep the screws for later and remove the
connector plate: on the back you will notice
a special connector.
C. To disconnect the special connector, press
the connector lock and separate the two
connectors. Remove the original connector
plate and put the AVM-amplifier module in
place.
D. The amplifier module uses the same
connector as the original connector plate:
press the lock and join the 2 connector parts
together.
E. Make sure the lock function is on: you
should hear a “click”. Double-check if the
connectors are well joined! If not, bad
connections could occur due to vibrations.
F. Put the amplifier module in place and use
the original screws to fasten the module.
FUNCTIONS
AVM-2 / AVM-3 AVM-1
ENGLISH OPERATION MANUAL
JB SYSTEMS

4/28 AVM-AMPLIFIER MODULES
1. FAN & VENTILLATION HOLES: during its operation the amplifier produces heat that must be
dissipated. The fans inside the amplifier must be able to evacuate the heat in the most effective way.
Therefore is it very important not to cover any of the ventilation openings as this may result in
overheating.
2. POWER SWITCH: Used to switch the internal amplifier on/off. The LED will turn on when the cabinet is
switched on.
3. MAINS INPUT: Mains input with IEC socket and integrated fuse holder, connect the supplied mains
cable here.
4. FILTER SWITCH: used to switch the integrated active filter on/off:
AVM-1: 100Hz low-cut filter, used to cut low frequencies to the speaker cabinet when used in
combination with an active subwoofer.
AVM-2/3: 90-250Hz adjustable hi-cut filter for use in active subwoofers.
5. SPEAKER OUTPUT: you can connect a second “passive” speaker cabinet to this Speakon output.
Connections are +1 and -1.
Attention: This output only supports 8Ω loads!!! Never connect a 4Ω speaker or more than one 8Ω
speaker cabinet to this output! This can damage the amplifier module. If AVM-2 is mounted in VIBE30
Mk2 it is NOT allowed to connect an additional passive speaker!
6. FILTER CONTROL: (only on AVM-2 / AVM-3) used to adjust the hi-cut crossover frequency of the
internal crossover. You can adjust the frequency between 90Hz and 250Hz: perfect to make an active
system based on a subwoofer + top cabinet! For most subwoofer applications a crossover point
between 90Hz and 150Hz is OK, however while listening and comparing you will easily find the optimal
settings for your system.
7. LINE INPUT/OUTPUT: This input accepts both balanced and unbalanced line level signals. The output
makes it possible to connect several speaker cabinets to the same line output of a mixer.
8. MASTER LEVEL: Used to set the volume of the amplifier. 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. power of the
VIBE-cabinets they will be used in. 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.
9. TRIMMER: Used to limit the input level of the line input, with this trimmer you can set the maximum
power of the amplifier, even if the master level (8) is set to maximum.
10. CLIP LED: is lit when the limiter is working. You are working on the limits of the amplifier, please turn
the volume a little down.
