RKB VR36-VR33S PA SET

RKB VR36-VR33S PA SET

Precizare: sistemul prezentat, testat in show-room-ul magazinului stage-prolighting.ro de tehnicienii nostri, reprezinta la ora actuala cea mai buna oferta de sonorizare a noastra sub raportul calitate/pret.

Calitatea intregului sistem proiectat integral in Germania este realmente comparativa cu cea a sistemelor de 3-4 ori mai scumpe, brand-uri de renume. Un sunet cald, placut, puternic si clar in toata banda de frecvente. La acest sistem detaliile fac intregul, referindu-ne in mod special atat la finisaje, cat si la faptul ca pentru o aplicatie LIVE, (in care este foarte important sa se distinga clar fiecare instrument si vocea over the top), califica sistemul printre cele mai bune. In plus, deloc de neglijat, ar fi de mentionat aceasta facilitate oferita de subwoofere prin prezenta celui de-al doilea difuzor (de 15”, dedicat mediilor joase) care nu numai ca reduce considerabil dispersia joaselor nedorite si neclare pe laterale, dar impinge joasele atat in fata, cat si in spate (spre scena, exact ca un ejector) completand banda frecventelor joase si medii-joase alaturi de monitoarele standard amplasate, oferind astfel acea „grasime” atat de necesara pentru ca toti entertainerii sa se simta bine, beneficiind de o monitorizare completa si buna. De la sectia ritmica, pana la solisti si solisti instrumentisti, toti vor simti acest aport de frecvente, desi toata lumea canta in spatele PA-ului. Tocmai pentru a obtine acest tip de control, multe trupe prefera sa cante in fata PA-ului, ceea ce este o greseala din toate punctele de vedere!!! (incepand cu eventualele microfonii aferente, cat si al stressului prin expunerea indelungata la decibelii ridicati peste masura acceptata –vis-a vis de distanta la care se afla). O astfel de practica poate duce in timp realmente la probleme generale de sanatate, nu numai auditiv. Ca idee, pentru a fi mai expliciti, sunand la magazin va putem pune la dispozitie tabelul standard de expunere admisa ca timp in fata nivelului decibelilor. De remarcat de asemenea cablajul (6 x 2,5mm – 4+ 2 safety) made in Japan cu Neutrik speakon, precum si sistemul de prindere si asigurare in bride intre sub-uri si/sau modulele line-array foarte bine gandit de inginerii germani, simplu si eficient, cu unghiuri variabile pentru inclinatii, reglabile atat la suspendarea cu fly-bar-uri, cat si grounded. Este asemanator cu cel de la d&b, cu pin-uri safety. Mastile metalice, prevazute cu un burete anti estompare fonica de cea mai buna calitate, pot fi inlaturate accesand cateva suruburi cu cap special, iar marginile (sina metalica de sustinere) sunt prevazute cu fante pentru lid-uri de protectie (neincluse) la toate modulele line-array. Pentru transport recomandam case-uri pe role (neincluse) pentru VR-36 (cate doua in case), altfel devin prea grele, iar pentru sub-uri dolly pe role (neincluse), un sub avand 66 de kg. Ca o ultima mentiune: Un sistem care surprinzator (desi ajunge in peak la 141 dB) suna bine si la 10W si la 100W si la 1000 W si la 10000W si e realmente o placere sa-l asculti. Magazinul nostru pune la dispozitia clientilor care vor achizitiona acest produs toate manualele de operare a componentelor incluse, instructiuni specifice traduse in limba romana, oferind atat asistenta tehnica necesara la primul montaj, cat si softurile speciale (unice) pentru optimizarea sistemului si editarea parametrilor DSP cu un simplu laptop. Configuratia de baza a procesorului DSP matrix pentru VR-36/VR33S vine deja preinstalata si protejata, fiind de fapt User 1care se autoincarca direct de la pornirea procesorului. Este contraindicata folosirea acestui sistem fara acest preset (care insa permite ajustari). Folosirea sistemului fara procesor, legand pur si simplu speakerele la un amp fara DSP exclude garantia, deoarece acestea pot avea 1+/- cu 2+/- in link, ceea ce poate distruge speakerele prin anularea crossoverarilor si a celorlate filtre impuse. Din seria amplificatoarelor cu DSP incorporat acceptate sunt: LabGruppen, seria PLM, sau PLM+ si Powersoft. Fiecare au software aferent si diferit. Alte procesoare de sistem care pot fi folosite sunt Lake (SUA) LM 26, sau LM 44, pentru care sunt deja facute preseturile VR36 si VR33S. Sistemul se ataseaza foarte bine atat cu mixerele analogice, cat si digitale. A fost testat in toate felurile. Rezultate excelente.

RKB VR-36 -VRS33 -AK-4130 -PA Configurable reprezinta un sistem care poate fi configurat la cererea clientului. Pretul exprimat pentru acest sistem este pentru urmatoarea configuratie:

Intregul sistem astfel configurat poate fi testat in show-room-ul magazinului stage-prolighting.ro, fiind o configuratie de baza pentru o aplicatie band LIVE, DJ, sonorizare cu pana la 150-200 de persoane.

Configuratia standard pentru un sistem capabil sa faca fata fara probleme la un eveniment cu 500-600 persoane este insa 4 x VR36 + 4 x VRS33 cu doua amplificatoare AK-4130  care va opera in 4 Ohm/canal, obtinandu-se o putere totala de 16 kW, cu crossoverarile aferente facute de procesorul de sistem RKB DX448. De remarcat este flexibilitatea sistemului in sensul upgradarii ulterioare pentru sisteme mai mari, sau chiar aplicatii outdoor. Pentru cunoscatori, care stiu ce fel de clone sunt toate aceste componente, excelent realizate, este de asemenea de remarcat raportul calitate/pret exceptional, fiind practic de 4 ori mai scazut pretul fata de originale la un randament practic asemanator, ceea ce face acest sistem sa fie cat se poate de competitiv. Sistemele se configureaza la cerere si pot fi aduse by air in numai 10 zile direct de la producatorul Hongxiang ai carui re-selleri oficiali suntem incepand cu acest an. Achitarea comenzii se face integral in avans, iar pentru cantitati mai mari plata este garantata cu Bilet la Ordin. Garantia oferita este de 2 ani pentru fiecare component in parte. Toate incintele sunt vopsite cu vopsea germana, au componente numai neodym, ceea ce le confera fiabilitate sporita. Electroliticii din amplificator sunt Siemens, iar finalii sunt de cea mai buna calitate. DSP-ul managementului de sistem este o completare importanta a amplificatorului, astfel incat utilizarea in absenta unui procesor de sistem se exclude, care avand 4 in si 8 out este suficient pentru upgradari cu multiple amplificatoare (max 4 per rack). Calitatea sunetului este foarte buna, avand claritate in toata banda de frecvente bine distribuita. Pentru aplicatiile LIVE indoor cu pretentii, configuratia minima recomandata este dubla fata de cea prezentata, deci cel putin 4 x VR36 + 4 x VRS33. Sistemul de prindere este de asemenea flexibil, top-urile si basii putand fi atat suspendati, cat si grounded. Pentru suspendare sunt necesare si disponibile fly-ing bar-uri dedicate, precum si toate celelalte accesorii suplimentare (neincluse in pret).

Professional line array speaker boxes with sand texture paint pa system high output outdoor performance audio box
 
Model number: VR36 / VRS33
 
Characteristic:

• VR36 is decided to work in large-scale events in touring business or for installations in large halls and stadiums.
• With specially-designed speakers, durable and stable neodymium magnet drivers, high-quality birch plywood enclosures, VR 36 provides you with a brand new concept of sound reproduction.
• It is an extraordinarily compact Vertical Line Array system, coupled with brilliant, crisp speech intelligibility, tone quality and dynamics, and low-mid power you’ve only seen up to now in much bigger systems.  VR36 can satisfy you with such a compact box, saving your manpower, saving your cost, however, making you surprised at its performance.

• VRS33 is a unique design, with an 18 inch subwoofer at the front and a 15 inch subwoofer at the back. Dual-channel control gives a forward directed bass radiation with a damping of up to 15 dB in the rear. This results in a much more solid, tight and musical bass sound, especially in environments with difficult acoustics. Also actors on the stage and neighbors behind the venue are being spared from too much low frequency energy.
• Many different stacking variants are available with the VRS33. With the same system width and the same rigging gear, the VRS33 can be integrated inconspicuously into a VR36 array. But also classic L-R-stacks, horizontal rows in front of the stage and complete vertical bass arrays are possible. Either stacked or flown.
