III. Electronic overview:
FR-X 12a uses a 2 x 1100 Wrms amplifier while FR-X 15a uses a 2 x 1700 Wrms one.
Both are
digital high efficiency amplifier that integrates 4 useful preset.These presets are based on the
fact that mutual coupling between subwoofers influences the displacement of each transducer's cone in the enclosure.
Preset have been designed to optimize the displacement and ensure best working conditions.
Diagnosis and status Leds.

1. The main voltage must be ALWAYS earthed to protect user in case of
2. ALWAYS replace the fuse with the same type and value (T10A/240V).
3. Make sure that the power switch is set to "OFF" before you connect the devices
4. A good cable improves the sound quality. Input cables should be as short as possible.
5. If long cable are necessary, you should use balanced cables.
Dagnosis and status Leds:
Limit: ON when output signal is @-3dBspl of the peak.
Temp: ON when working temperature is too high. The internal fan runs at 100% of its speed *
Signal: ON when a signal is detected at the input of the cabinet.
Ready: ON after a few seconds, the system is ready for use.
