5. OPTIONS
In this section will explain the different available options for the crossovers FA-524 and
FA-724.
Each crossover way provides of two insertion points, in those that could insert equalizer
cards or delay cards. Upon providing of two insertion points, each way could provide of two
equalization points, or a equalization point and a delay (The delay card only could insert in one
of them, for the one which could not provide of two delay points).
FREQUENCY CARDS (TC-66)
Each frequency card provides of two filters, one high pass and another low pass, that
defines the relevant frequency between two ways, with a slope of 24 dB/ octave LINKWITZ-
RILEY type. The relevant frequency attenuation is 6 dB. The crossovers are given with the
standard relevant frequencies that are shown in the following table:
STANDARD RELEVANT FREQUENCIES PROVIDE BY FACTORY
WAY
FREQUENCIES
SUBWOOFER (SW)
82Hz,100Hz,120Hz,150Hz.
OTHER WAYS
100Hz, 120Hz, 150Hz, 180Hz, 220Hz, 270Hz, 330Hz, 390Hz, 470Hz, 560Hz, 680Hz,
820Hz, 1KHz, 1K2, 1K5, 1K8, 2K2, 2K7, 3K3, 3K9, 4K7, 5K6, 6K8, 8K2.
The supply of any other relevant frequency that the specified will be an option previous
consults to the commercial department.
EQUALIZER CARD (TE-67)
In certain installations it is advisable insert equalization points in order to improve the
system frequency response, for which the crossover provide an optional equalizer card.
Inserting an equalization directly in the crossover is cheaper than utilize an graphic equal-
izer, and also avoids unwanted manipulations .
The optional equalizer card provides a full parametric equalization point, for the one
which could define the three variables that setup a equalization point: gain, bandwidth and
center frequency.
Could provide of two equalization points for way how maximum, installing two equal-
izer cards.
DELAY CARD (TD-69)
Sometimes are necessary establish a delay between ways, in order to balance the
delays produced in them due to the design of the cabinets, and so improve their phase
coherence. For it the divisors provide of an optional delay card.
The optional delay card configuration could request of 2 ms (70 cm), valid until 2 KHz
and of 500 µs (17 cm), valid until 8 KHz. At high frequencies, the card is still working, but the
time delay decreases progressively.
The delay card of 2 ms. provides seven steps of 250 µs (8,75 cm) and 62,5 µs (2,12 cm)
for the 500 µs one and a adjustable linear step through a potentiometer of 0 to 250 µs for
the 2 ms delay card and of 0 to 62,5 µs for the 500 µs one.
