FA-524
The FA-524, configured in four mono
ways, has 4 frequency cards at positions 2,
3, 4 and 5. Normally the subwoofer will go
overlapped with the low output, because of
what the frequency card at position 2 will go
overlapped. The correspondence of them
gone out with the component overlay of the
crossover is showed in the next picture.
THREE MONO WAYS
The FA-724, configured in three mono ways,
has 3 BYPASS cards placed at positions 4, 5
and 6, and 3 frequency cards at positions 1, 2
and 3. Normally the subwoofer will go over-
lapped with the low output, because of what
the frequency card at position 1 will go over-
lapped. The correspondence of them gone out
with the component overlay of the crossover is
showed in the next picture. We will also have
the LOW CH2, the MID CH2 and the HIGH CH2
outputs at FULL RANGE.
The FA-524, configured in three mono ways, has
1 BYPASS card placed at position 5, and 3 frequency
cards at positions 2, 3 and 4. Normally the
subwoofer will go overlapped with the low output,
because of what the frequency card at position 2 will
go overlapped. The correspondence of them gone
out with the component overlay of the crossover is
showed in the next picture. We will also have the
HIGH CH2 output at FULL RANGE.
LIMITER ADJUSTMENT
Each crossover way has an adjustable limiter between ±15 dBv (0dBv = 0,776 V. RMS),
in steps of 1 dBv, with an attack and recovery time optimized to each relevant frequency (the
attack and recovery time adjusts are placed in the frequency cards), and with a compression
ratio of 10: 1.
The limiter adjustment takes place by means of a switch block (one per band), each
block contains 6 separate switches. The correspondence of each switch block with the way
to which belongs it show in the following table:
