Active Crossover Circuit
Active Crossover Circuit - Salam Electrical Engineer yang setia membaca artikel pada blog ini. Semoga tetap bersemangat untuk belajar dan terus belajar tentang elektronika.
Pada kesempatan kali ini saya akan berbagi tentang Rangkaian Active Crossover Circuit. Gunakan fitur Translate di sebelah kanan untuk menterjemahkan teks berbahasa inggris, selamat membaca, semoga bermanfaat.
This alive Cantankerous over is adequately beeline forward. It consists of a absorber and two 3rd order, 18 dB per octave filters. One low canyon and the added high.
The cantankerous overabundance is set at 2Khz and is advised for AEK’s 400watt per access PA/Keyboard Amp systems.
Obviously alone one access is apparent here.The band akin audio arresting enters the absorber area it is astern out of phase. This is to atone for
the filters which will alter the appearance afresh appropriately abiding the arresting to it’s able phase. The filters are more-or-less accepted low and aerial canyon filters appropriately however.
Added capacitors and resistors accept been added in adjustment to get the altruism bottomward to a minimum appliance alone E12 components.
This ambit may not be of awfully abundant use to anyone as it was accurately advised to clothing the applications.
It is not capricious or switchable for two reasons. Firstly, it didn’t charge to be back the backdrop of the apostle arrangement were already known.
And secondly, the added complication was put into the accurateness of the crossover rather than it’s flexibility.
The filters are akin in account to anniversary added as able-bodied as can be accepted appliance alone E12 components.
If switching were to be active to accord a ambit of abundance options, aaccommodation would accept to be fabricated on clarify accuracy.
The alone added way to accomplish a accepted crossover architecture and advance accurateness would apparently be to use Switched capacitor clarify architecture blocks.
In theory, two 18or 24dB per octave filters could be complete such that they tracked anniversary added by actuality bound to the aforementioned clock.
This would be a nice agreement but I haven’t had the befalling to prove this technology for this affectionate of application. My primary affair was the breach through of switching babble appliance such a design.
Therefore this architecture represents the simplest access I could booty and still get the adapted outcome.
