Guest En1gma Posted July 23, 2007 Share Posted July 23, 2007 Scrie ca are 75W, mono. In spate are 2 iesiri. Zice ca 4 ohm minimum.Daca ar fi sa conectez un 4x12", ce impedanta de iesire ar trebui sa aiba? ( cabinetul are 2 iesiri, cate 2 difuzoare legate intre ele, initial vroia sa fie stereo ) http://www.thomann.de/gb/line6_spider_iii_hd_75.htm Link to comment Share on other sites More sharing options...
dass101 Posted July 24, 2007 Share Posted July 24, 2007 In mod normal cabinetele de 4x12 au 3 posibilitati de conectare: 4 si 16 ohmi mono, sau 2x8 ohmi stereo. Daca scrie pe amp 4 ohmi minim, tb sa conectezi o boxa cu minim 4 ohmi ... La amplificatoarele solid state nu e asa critica potrivirea impedantelor de iesire cu cea a boxei, trebuie doar sa nu fie boxa mai mica decit ampul. Pentru transferul maxim de putere, ele trebuie sa fie egale. Link to comment Share on other sites More sharing options...
Guest En1gma Posted July 24, 2007 Share Posted July 24, 2007 consultand http://colomar.com/Shavano/4x12wiring.html , cred ca am sa le leg in serie-paralel ptr. a obtine o impedanta totala de 8 ohm. Acum ma gandesc cum as putea sa le leg cele 4 difuzoare ( 8 ohm ) sa iasa o impedanta de 4 ohm in total.. dar nu prea cred ca se poate.Oricum le-as lega, ar iesi ori 2 ohmi, ori 8, ori 32.

dass101 Posted July 24, 2007 Share Posted July 24, 2007 Ai cab 4x12 cu difuzoare de 8 Ohmi? that's strange.. Oricum, pentru ce iti trebuie tie e OK si daca obtii o impedanta generala de 8. Link to comment Share on other sites More sharing options...
Guest En1gma Posted July 24, 2007 Share Posted July 24, 2007 E cabinet home-made. : http://forums.rgc.ro/index.php?showtopic=7049&st=0 Am 2 difuzoare pe 8 ohm. Ma gandesc sa mai cumpar doua buc pe 4 ohm,atunci as putea sa le leg sa iasa 4 ohm in final(8-8-4-4) Link to comment Share on other sites More sharing options...
