1. IMPORTANT NOTE
We Thank you for purchasing our FAP30L Active Filter with Limiter. IT IS VERY
IMPORTANT that you carefully read this manual BEFORE CONNECTING this equipment in order to
obtain its maximum performance.
We also recommend you our authorized Technical Services whenever any maintenance task
should be necessary, so that optimal performance of the equipment shall be guaranteed.
1.1. Precautions
This apparatus must be earthed through its mains cable.
Do not expose the unit to rain or water splashes, and do not place liquid containers or
incandescent objects like candles on top of the unit.
Any change in the configuration of the unit must be carried out by a qualified technician.
Should any connection / disconnection task be done, always disconnect the unit from the mains
supply.
There are no user serviceable parts inside the unit.
2. INTRODUCTION
The FAP30L offers the best solution to any professional multiamplification requirement,
considerably improving the acoustical efficiency of the loudspeakers by both avoiding the use of
passive components and making possible the operation on the optimal frequency response of the
loudspeakers.
The way-independent-limiters stop and compress input signals that could yield to output
levels higher than adjusted and, in consequence, it can be used as a sound pressure limiter.
The FAP30L can be configured in stereo mode (two ways per channel/one crossover
frequency) or in mono mode (three ways per channel/two crossover frequencies).
The crossover frequencies are easily selected by means of the switches on the back panel
and the wide range of adjustment makes possible to fit any real-life electroacoustical system that you
can ever face to. The fact that crossover frequencies are adjusted on the back panel, avoids dangerous
handling inside the equipment while also prevents direct access to the adjustments made by the
installator.
2.1. General characteristics
- Crossover frequencies programming through switches on the back panel and from 25Hz to 7750Hz
with the following adjustment characteristics:
* From 25Hz to 775Hz, 25Hz step.
* From 250Hz to 7750Hz, 250Hz step.
All the filters are Butterworth type with a fixed slope of -18dB/octave.
