MAINS EARTH LINKED WITH THE CROSSOVER ELECTRIC GROUND
MAINS EARTH LIFTED FROM THE CROSSOVER ELECTRIC GROUND
CAUTION: Sometimes, lifts the mains earth, using a ground-lift connector,
the one which undoes the ground loop also, but this is very dangerous,
since if for any circumstance part of the mains signal is derived to the
chassis, could cause a short-circuit through our body, upon having elimi-
nated one of the working precautions of the unit. For this circumstance,
NEVER
lift the mains earth (lift the crossover EARTH-LINK switch) in order to
avoid possible accidents.
4. OPERATION
The crossover utility, is divide the audible band (20Hz to 20KHz) in smaller bands,
whose sum restores the audible band again. Once separate and tried meetly, the different
bands are amplified and reproduce for separating giving a multiamp system like result. This
division is carried out so that the different cabinet ways only receives the part of the band that
they are capable of reproducing, avoiding possible breaks, and an unnecessary warming up,
and so that the power amplifiers only amplify the signal that is going to reproduce the cabinet
way that are feeding, avoiding that unnecessarily warms, amplifying signals that are not been
going to reproduce.
MODES OF OPERATION
The crossover can be configured as either a stereo mode or mono mode. The
crossover configuration is shown in the front panel of the unit by the MODE LED
indicator (STEREO / MONO).
In STEREO mode operation, will provide of two totally independent crossover channel
inputs, with 2 or 3 ways for the FA-724 and 2 ways for the FA-524.
In MONO mode operation, will only have one input channel: CH1 (the channel CH2 will
be disabled, for the one which any signal that inserts in it, will be lost, since it won't appear in
the output), and of 4, 5 or 6 ways for the FA-724 and 3 or 4 ways for the FA-524.
Besides these mentioned ways, exists an additional subwoofer mono way (SW), whose
signal will be the sum of the input channels CH1 and CH2 in stereo mode, and the input
channel CH1 in mono mode. It is important emphasize that in stereo mode, this output upon
adding the signals of the input channels CH1 and CH2, if only inserts signal for one of the
input channels, will only have the half of the signal in the output.
