Ecler FAP30L Notice D'emploi page 6

The 'CHI LOW' output (30) is the left-channel bass-way and the 'CHII LOW' output (29) is the
right-channel bass-way. Both outputs shall be connected to the bass amplifier.
The 'CHI HIGH' output (28) is the left-channel high-way and the 'CHII HIGH' output (27) is the
right-channel high-way. Both outputs shall be connected to the high amplifier.
WARNING:
TAKE SPECIAL CARE WHEN WIRING THIS CONNECTIONS AND MAKE SURE THAT
THE BASS SIGNAL IS NOT SENT TO THE HIGH AMPLIFIER BECAUSE THIS COULD SERIOUSLY
DAMAGE THE LOUDSPEAKERS.
The input signals to the FAP30L whether from a mixer or an equalizer shall be connected to
the 'CHII INPUT' and 'CHI INPUT' connectors (38 & 39).
The crossover frequency between both ways is selected through the SWITCHES of the
'CROSSOVER FREQUENCY SELECTOR. The upper line of switches corresponds to the CHII
crossover frequency selector while the lower one is for the CHI. The crossover frequency must be the
same for both channels because the configuration is for a stereo system.
The 'x10' switch (31) multiplies the frequency values of the switches (32-36) by a factor of
ten, so that the new frequency values become 250, 500, 1000, 2000 and 4000Hz. The crossover
frequency value is obtained adding the 'weights' of the activated switch or switches. For example, if only
the (34) switch is on the crossover frequency will be 100Hz. If the (34-35-32) switches are on then the
crossover frequency will be 325Hz, which is the result of adding the 'weights' of each switch (25Hz +
100Hz + 200Hz = 325Hz).
* MONO TRI-AMPLIFIED CROSSOVER FREQUENCY SELECTION AND CONNECTION.
The FAP30L can also be configured in tri-amplified mode. This kind of configuration needs
one FAP30L unit per channel. When the 'WAYS' switch (37) on the back panel is on the FAP30L will
operate in mono tri-amplified mode and the '3W' LED (22) on the front panel right hand will lit. When
operating in tri-amplified mode the valid labels on the front and back panel are the ones in bracketts.
WARNING:
IN 3-WAY MONO OPERATING MODE, THE CHANNEL II (LOW) OUTPUT LED AND THE
LIMITER CIRCUIT WORK ON THE BAND-PASS FILTER.
WARNING:
NEVER ADJUST
ADJUSTMENTS SHALL ALWAYS BE DONE WITH THE 'POWER' MAIN SWITCH (23) OFF.
The 'LOW' output (30) is the bass-way, the 'MID' output (29) is the medium-way and the
'HIGH' output (27) is the high-way. The 'UNUSED' output (28) is not used in this mode.
WARNING:
TAKE SPECIAL CARE WHEN WIRING THIS CONNECTIONS AND MAKE SURE THAT
THE BASS SIGNAL IS NOT SENT TO THE HIGH AMPLIFIER BECAUSE THIS COULD SERIOUSLY
DAMAGE THE LOUDSPEAKERS.
The input signal to the FAP30L whether from a mixer or an equalizer shall be connected to
the 'INPUT' connector (39).
