salut
Donc mon objectif est de réalisé mon filtrage actif entierement à partir de mes amplis (3voies +sub )
un 603X et un 604X
jusque là pas de probleme les amplis permettant de faire presque tout ce qui existe en terme de filtrage à partir du moment ou c'est à pente 12db ou 24db
le probleme est que je ne dispose pas de sip MAIS que j'ai trouvé ça dans la faq de Xtant.com

How do I create Custom Crossover Frequencies for Xtant X series amplifiers?
In order to determine which 1/8th or 1/4 watt resistor to use, refer to the attached charts. The charts contain the SIP code numbers along with their corresponding frequency value. Simply choose the crossover frequency desired and translate the SIP code number into a resistor value. Next, load six resistors of the determined value into the SIP Socket. You've just created a custom crossover frequency. (See above)
The SIP codes are simple to understand. The last number of the SIP
code represents the number of zeroes to add to the first two numbers of the code. This number determines the value of the resistors to use. (Example: SIP code number 682 = 6800 OR 6.8 K Ohms.) To install the resistors, "J" bend and insert each resistor into the SIP socket. Do not allow the resistor leads to touch.
Steps to creating a custom crossover frequency sip
1. Choose a crossover frequency from the chart and note the
corresponding sip code.
2. Translate sip code into a resistor value.
3. Load 6 - 1/8th or 1/4 watt resistors into the sip socket isolating the leads.

Creating a Subsonic Filter: When using a 24dB octave crossover,
place the jumper in the bandpass position. Select a lowpass frequency SIP (90Hz is already included). Remove both high pass frequency SIP's of the sub channel to create a 15Hz subsonic filter or create the frequency of your choice using the chart on this page.

bon jusque là ça va à peu pres pour la traduction mais cette phrase me pose un peu des problemes quant à son interpretation
:Load 6 - 1/8th or 1/4 watt resistors into the sip socket isolating the leads.
est-ce que cela peu se traduire par mettre 6 resistance 1/4 de watts dans le support sip en les isolant les unes des autres ?
