Used EAW KF755 F - SB730 Subwoofer PA SET

 

 

Used EAW KF755 F - SB730 Subwoofer PA SET este un sistem complet de sonorizare compus din urmatoarele produse:

Component	Nr buc
EAW – KF755 F Downfill Array Loudspeaker, speaker pasiv 1200W, 140 dB	8
EAW SB730 Subwoofer, 2 x 12”, subwoofer pasiv, 1200W	4
Presonus 802, digital mixer	1
PL-Audio Power amplifier Rack , 10K 4 channel amplifier + 14K 2 channel amplifier + DSP speaker management processor + Power distributor + speaker signal distributor + rack case	1

Sistemul este second-hand, toate speakerele au fost refurbisate si verificate, conditia lor fiind buna, lucrand in parametri. Toate speakerele sunt produse in USA si sunt importate din Europa. Rack-ul de amplificatoare este Made in Germany si se importa simultan cu speakerele. Conditia amplificatoarelor si a procesorului DSP este ”like NEW”, avand in continuare o garantie oferita de 3 ani!!!, iar mixerul digital Presonus 802 mai are inca o garantie de 1 an!, stare acestuia fiind ireprosabila.

Intreg sistemul poate fi adus si livrat integral in 8-10 zile, plata acestuia facandu-se integral anticipat.

Solutia de sonorizare propusa este ” la cheie”. Sub raportul calitate pret, acest impresionant sistem (care de nou ar costa de 3 ori mai mult), avand o putere de 14400 W RMS, la un SPL atingand lejer pragul de 140 dB, poate fi considerat realmente un ”DEAL”. De patru ori mai puternic ca un XA, sistemul va incanta nu numai prin forta, dar si prin claritate, gratie DSP-ului german care va separa foarte bine frecventele inainte de cele doua amplificatoare 4 x 2500 W, respectiv 2 x 7000W. Distributia speakerelor si a subwooferelor este urmatoarea: din amplificatorul PL- 10K cate 2 top-uri pe canal in paralel, iar din amplificatorul PL-14K, cate doua subwoofere in paralel pe canal, asigurandu-se astfel maximum de randament pe tot sistemul. Pentru evenimente outdoor/indoor cu pana la 2000 de persoane, acest setup este mai mult decat suficient. De remarcat este si fiabilitatea produselor. Un sistem care ”nu te lasa”!

EAW – KF755 F Downfill Array Loudspeaker x 8

SPECIFICATIONS KF755

 

The KF755F 3-way tri-amplified full range system is the down-

fill companion to the KF750F array module.

Since the large mid frequency horn contains both the high

and

low frequency subsystems, the overall package is just 31-in

high. Still, the KF755F provides consistent wideband pattern

control in both the vertical and horizontal planes.

The large MF horn loads a specially designed 10-in midrange

cone whose geometry exactly matches the rear of its phase

plug assembly. By developing the driver and phase plug as a

single unit, pathlength discontinuities within the MF pass-

band have been eliminated without compromising the direc-

tional qualities of the source as all previous phase plug

designs have.

The 2-in exit/4-in voice coil HF compression driver is mounted

on an asymmetrical 35° x 35° constant directivity horn

mounted coaxially within the MF horn flare. Vertical coverage

is 0° to -35°.

The KF755F’s 15°-per-side trapezoidal enclosure features

eight 4-position flytracks (four each front and rear) that

accept industry-standard flyclips.

The KF755F provides optimized downfill coverage below flown

arrays or, when inverted, provides upfill balcony coverage

from ground-stacked arrays when flying arrays are either not

allowed or not desired.

At just 31-in tall and under 200 pounds per module, KF700

Series arrays are smaller, lighter, more efficient and, therefore,

more powerful than those built with other systems. These

smaller, lighter arrays are easier to fly, require less truck space

and permit more open sight lines to cover any given venue.

The KF750F works with a companion downfill module, the

KF755F to provide full range nearfield coverage below the

array. The KF755F’s smooth power response produces remark-

ably even SPL levels throughout the coverage area, allowing

it to be used as a stand-alone system when necessary in

applications demanding that coverage pattern.

DESCRIPTION

The SB730 is designed as a companion to KF730 Line Arrays,

but is suitable for other applications requiring high output at low

frequencies in a highly compact format. Used in arrays of two or

more, the SB730s couple to extend the low frequency response.

The unique enclosure shape both enhances the acoustical per-

formance and serves to provide a solid base for a

ground-stacked KF730 array. The SB730 enclosure is 1.5 times

the height of a KF730, which allows attractive KF730/SB730

arrays to be assembled in a 3:2 ratio.

The "clam shell" arrangment of its two, advanced design, 12

inch woofers provides tighter driver coupling to increase output

and maximize LF "punch". A massive port radiates the consider-

able energy needed at the enclosure's tuning frequency to com-

plement the KF730s output at other frequencies.

Several different wiring configurations are permitted. In addition

to Neutrik® NL4 input and loop-through connectors, an NL8

connector accepts amplifier outputs for both SB730s and

KF730s using a single amplifier rack cable. Additional SB730s

and KF730s are then daisy chained from one SB730. This

allows powering up to eight KF730s and four SB730s with just

four amplifier channels.

The enclosure features integral skids and companion recesses so

that enclosures interlock to stabilize stacked SB730s. Heavy duty

handles and an optional caster pallet facilitate transporting.
