2. INTRODUCTION The KF730 Line Array represents EAW’s latest technology for arrayable loudspeakers. The KF730 is a small format line array system for venues with listener distances up to about 200 ft / 65 m. The KF730 Series is designed to provide the highest output possible from a compact line array format. The Series includes the 3-way, bi-amplified KF730 full-range and the complementary dual 12 in SB730 subwoofer.
4. KF730 ARRAY DESIGN 4.1 KF730 WIZARD Use the KF730 Wizard for designing KF730 arrays. It can be found in the Downloads/Software section of the EAW website (www.eaw.com). The Wizard’s primary function is to determine the configuration that will provide the best vertical performance for a given application. Various venue dimensions are entered that allow the Wizard to calculate the resultant array performance.
The horizontal pattern also features “soft shoulders” that provide consistent frequency response to well beyond the nominal -6 dB points. These soft shoulders can provide up to 150° of “usable” horizontal coverage, albeit at somewhat reduced level. This off-axis performance also provides good acoustic integration with side-fill arrays. In some cases, these shoulders may be sufficient for side-fill purposes. 4.2.
When flown as part of a KF730 array, the SB730s should be the uppermost enclosures in the array. In this application, the SB730s are suspended flat-fronted, with the KF730s suspended below in the curvature determined by the KF730 Wizard. When flown separately, SB730s should be flown so that the spacing between the line of SB730 enclosures and KF730 enclosures is about 1 ft / 0.3 m. The SB730 should be suspended in a flatfronted configuration. 4.4.
5. ARRAY OPERATION 5.1 OVERVIEW The operation of a KF730 Series system involves: 1. Understanding the principles on which it operates. 2. How to electronically configure it for a specific task. 5.2 ENGINEERING DESIGN How a KF730 Array works: Divergence Shading In almost any venue, there are significant differences in distance from the loudspeaker array to the nearest and farthest audience members.
5.4.1 Factory Signal Processing Settings The signal processing adjustments determined by EAW for the KF730 Series Array should be fully implemented “as is.” These settings are determined from extensive measurements in typical venues as well as the theory of curved sources from the acoustical work of physicists Harry Olsen and Leo Beranak. As such, they will normally provide excellent results in a variety of venues. The signal processor settings are provided in the KF730 Wizard.
The following tables list the rms voltage limits for the KF730 and SB730. Because of their higher impedance design, multiple KF730s and SB730s can be powered from single amplifier channels. NOTE: The rms Voltage Limit listed for each sub-system (LF, MF/HF, SUB 1/2, or SUB 1 and SUB 2) is the same for any enclosure quantity. The wattages are calculated using the Voltage Limits and the overall nominal impedance for the each listed quantity of KF730 and SB730 loudspeakers.
5.7.3 Selecting an Appropriate Amplifier Size Rule Of Thumb If a KF730 Line Array is used for professionally operated concert applications, a rule of thumb can be applied. Where the full output capabilities of the loudspeakers may be needed to achieve appropriate acoustic output levels, EAW recommends amplifiers with power ratings up to twice the wattages listed in the above charts. This provides a peak voltage capability of 6 dB above the specified rms voltage limit.
5.8.2 SB730 Connections There are three Neutrik NL4MP and one NL8MP connectors on the rear of each SB730. The connectors mate, respectively, with Neutrik NL4FC and NL8FC in-line cable connectors. SUB INPUT/OUTPUT NL4MP (each of two) PIN 1PIN 1+ PIN 2PIN 2+ SB730 SB730 SB730 SB730 SUB 1SUB 1+ SUB 2SUB 2+ 1. Use as the input to the SB730. 2. Use the second connector to loop SUB signals to additional SB730s. 5.8.
LF 5.8.4 KF730P Input Connections There are two 4-terminal barrier strip connectors on the rear of each KF730P. The connectors are wired in parallel so that the second connector can be used to loop LF and MF/HF signals to additional KF730s. The connectors accept stripped wire ends or wire lugs. 5.8.5 SB730P Input Connections There are two 4-terminal barrier strip connectors on the rear of each SB730P.
6. RIGGING KF730 Series arrays are intended to be suspended or ground-stacked. This chapter details how to physically configure KF730 Series arrays. The following are the recommended methods for most situations. Specific situations may require other methods. It is the user’s responsibility to determine the viability and safety for alternate methods and implement them accordingly. KF730 and SB730: The procedures to suspend and ground-stack KF730s and SB730s are detailed in this chapter.
For a given quantity of SB730: Max quantity KF730 = 18 - (1.5 x quantity SB730) Example, given five SB730: 18 - (1.5 x 5) = 10.5 which rounds down to a maximum quantity 10 KF730s For a given quantity of KF730: Maximum quantity SB730 = (18 - quantity KF730) / 1.5 Example, given eight KF730: (18 - 8) / 1.5 = 6.667 which rounds down to maximum quantity 6 SB730s 6.
6.4.3 Quick Release Pins Each KF730 is supplied with six 1.5 inch Quick Release Pins. Four are used for attaching enclosures together or to the Fly-Bar. Two are used as locking pins for the rear Hinges. See “Locking Pins” Section 6.4.5. Each SB730 is supplied with four 1.5 inch Quick Release Pins used for attaching enclosures together or to the Fly-Bar. 6.4.
KF730 FLY-BAR HINGE TUBE HOLES DANGER: Each Hinge Tube on the Fly-Bar has two Quick Release Pin holes. When suspending KF730 or SB730s from the Fly-Bar, always use the upper hole for attaching the enclosure Hinges. The lower hole is not load-rated and is to be used ONLY for attaching ground-stacked enclosures when using the Fly-Bar inverted as the base of the stack. Failure to follow this warning may result in damage to the equipment damage, injury, or death.
6.5 PALLETS 6.5.1 KF730 Face Pallet The KF730 Face Pallet is a wheeled pallet that holds two KF730s face down. Routing on the underside of the pallet allows stacking loaded pallets two high. Except for the first enclosure attached to the Fly-Bar, the enclosures remain on the pallet when attaching them to an array. The lip around the outside edge helps prevent the enclosures from sliding off the pallet. The pallets outside dimensions of 30 in x 22.
6.7 SUSPENSION PROCEDURES The basic procedure for suspending KF730s and SB730s or a combination of both is similar. What varies is how different pallets affect handling of the enclosures when being suspended. In all cases, it is recommended that KF730 enclosures be attached to an array one at a time. The SB730 enclosures may be attached two at a time. IMPORTANT NOTE: Always suspend all SB730s over the KF730s. In all cases, reverse each procedure for unrigging the array.
6.7.4 Attaching SB730s to SB730s Already Suspended NOTE: SB730s should always be flown tight-packed to each other. 1. 2. 3. 4. Move an SB730 Pallet so its SB730 is positioned under the bottom SB730 of the array. Remove the four Quick Release Pins from the Hinges of the SB730 on the pallet. Lower the array until the bottom SB730 barely touches the SB730 on the Pallet. Slide the four Hinges of the SB730 on the pallet into the suspended SB730’s Hinge Tubes. Align Hole 2 of each Hinge with the Hinge Tube Hole.
5. Attach each Hinge to the Hinge Tube by inserting a Quick Release Pin (removed in Step 2) through both. 6. Insert a Quick Release Pin (removed in step 2) into each of the enclosure’s rear Hinge Tubes as a locking pin. See “Locking Pins” Section 6.4.5. 7. Lift the Array, with the KF730 attached only by its rear Hinges, to a comfortable working height for the next step. 8. Employing two people, one lifts the front of the KF730, rotating it on the attached rear Hinges. 9.
6.8.2 Stacking Additional Enclosures (SB730 as the base) CAUTION: When attaching Hinges to Hinge Tubes in step 5 for an SB730, position the SB730 so it lies flat on the SB730 below it. In step 5 for a KF730, use the correct holes as determined by the KF730 Wizard or by the user-desired angles to achieve the desired splay angle. Failure to follow this instruction can result in poor acoustical performance. 1.
6.8.5 Stacking Additional Enclosures (Fly-Bar as the base) CAUTION: When attaching Hinges to Hinge Tubes in step 5 for an SB730, position the SB730 so it lies flat on the SB730 below it. In step 5 for a KF730, use the correct holes as determined by the KF730 Wizard or by the user-desired angles to achieve the desired splay angle. Failure to follow this instruction can result in poor acoustical performance. 1.
