RKB Live Setup SET

RKB Live Setup SET se compune din 6 module line-array fiecare avand cate 2 x 10 " neodym si 1 x 3"neodym driver, 2 subwoofere 1 x 18"si 2 sub-Infra 2 x 21". Intreaga banda de frecventa de la 27 Hz la 19000 Hz fiind acoperita la o putere apreciabila de 14000 W RMS, acest sistem de speakere astfel configurat face fata cu brio la orice tip de aplicatie LIVE, sau DJ. Deoarece toate speakerele sunt pasive recomandam amplificatoarele din seria FP, respectiv 10000Q si 14000Q, primul in 4 canale deservind pe un canal cele doua suburi de 18" in paralel, pe celelalte 3 canale fiind cate doua top-uri in paralel, iar FP14000Q va deservi cele doua Infra-Sub. Totul sub controlul unui procesor de sistem 2 in-6 out care in primul rand va aplica crossoverarile necesare pentru fiecare canal in parte. La acest sistem, pentru un raspuns cat mai bun si exact este foarte important reglajul delay-ului din management sistem, deoarece joasele trebuie aliniate cu atat mai mult cu cat avem doua tipuri de subwoofere, de asemenea si reglajul sub-armonicelor, altfel sistemul va fi dezechilibrat, iar "muscatura" joaselor nu va fi aliniata cu topurile care vor avea raspuns mult mai rapid. O aliniere corecta ca raspuns va transforma acest sistem intr-o mica bestie. In absenta unui procesor de sistem, folosind doar amplificatoare fara DSP, acest sistem nu va da nici 40% din randamentul si claritatea sunetului pe care o poate oferi. Un dbx (de ex) 260 care sa deserveasca sistemul ar fi numai bun. De asemenea, in special in aplicatiile LIVE, o compresie marita pe cele doua Infra (facuta ori din procesorul de sistem, ori folosind cu compresor auxiliar) va mari claritatea joaselor la o diminuare a volumului cu pana la -10dB, facand sunetul si mai compact. Sub raportul calitate/pret, acest sistem in configuratia descrisa este mai mult decat competitiv, fiind ofertat de producatorul RKB la nici jumatate din pretul concurentei. Indicat mai mult pentru instalatii fixe, decat mobile, in special din cauza greutatii celor doua Infra (avand cate 150 kg fiecare), sistemul ramane insa clar o optiune in fata unui buget limitat. Reglat si operat corespunzator, sistemul uimeste atat prin claritatea sunetului, cat si prin forta lui. Produs recomandat de stage-prolighting.ro

Sistemul poate fi adus in 8-10 zile, import extracomunitar, cu plata integral in avans. Garantia oferita sistemului este de 2 ani!!

The Triple 21" passive subwoofer speaker challenging design comprises three 6 inch voice coil 21" transducers . A combined power handling of 3600 watts RMS and very high sensitivity result in foundation-cracking sub frequencies all the way down to 27Hz. Designed to work in conjunction, The Triple 21" passive subwoofer speaker has been tuned with all forms of dance music in mind. Lightning quick impulse response with low group delay and an 'in your face' style of presentation combine to make it an unforgettable experience.

It’s a total connection with the fundamental frequencies that give dance music its pulse – a connection only obtainable by entire submersion in the purest form of reproduction. The 18mm  plywood enclosure is equipped with one rear-mounted speakon NL4 connectors.

Features:

 

• Triple 21" passive subwoofer speaker, front: 2400W RATED/9600W PEAK POWER, Rear: 1200W RATED/ 4800W PEAK POWER.
• Voice Coil of the 21” driver is 6 inches. PHT voice coil wire inside and outside rounding and BAF voice coil bobbin, can endure high temperature.
• The cone papers and spiders are imported from UKM.
• Cardioid dispersion pattern avoids unwanted energy behind the system
• Greatly reduces the reverberant field at low frequencies, providing highest accuracy in low frequency reproduction
•  Selecting Hypercardioid mode in the amplifier optimizes the tuning of front and rear channels for a maximum rejection at the left and right sides behind the cabinet
• Wooden lid for front grill is provided, as well as wheels at the rear side is included.
