N°7 Crossblock settings
N°7 Crossblock is an exclusive high technology crossover offering 4480 different filtering combinations to adapt kit's characteristics to car's environment and to
your own tastes.
We advise you to refer to the Quality Control Certificate provided with each kit in order to know the reference setting (Fig. 1).
This setting corresponds to an optimized linearity obtained according to normalized measuring conditions (see file for more informations) and is a good base
to refer to before begining settings. The response curve may change according to vehicle acoustic, speakers location, woofer/tweeter distance and speakers
orientation. An adapted Crossblock setting will allow to have a flat response curve. We advise you to use a measure equipment (RTA) for a fine setting. We advise
you to note different settings in order to refer to them as often as you need.
S1 setting
It combines two settings in one. It changes low-pass crossover frequency values (12dB/octave). Steps "1" to "5" refer to different low-pass frequency values,
whereas steps "6" to "10" also refer to the same "1" to "5" values but a boost is included. Steps "6" to "10" are interesting in solving level losses due to woofer
location (low in the door for example). Steps "1" and "6" refer to the higher frequency pass, whereas steps "5" and "10" refer to the lower one (fig. 2).
S2 setting (Hi-pass)
This setting changes high-pass frequency values (12dB/octave). Step "1" refers to the higher frequency pass, whereas "7" refers to the lower one. The midrange
low-pass value remains fix (fig. 3).
S3 setting (Level)
Midrange level setting according to 8 values, 1dB per step. Step "1" refers to the higher boost whereas "8" refers to the lower one (fig. 4).
S4 setting (Level)
It is the tweeter level setting. Eight steps increase or decrease tweeter level (1dB per step). Step "1" refers to maximum level, whereas "8" refers to minimum one
(fig. 5).
