2. INTRODUCTION The CAF730 Line Array representswoodworxmax latest technology for arrayable loudspeakers. The CAF730 is a small format line array system for venues with listener distances up to about 200 ft / 65 m. The CAF730 Series is designed to providethe highest output possible from a compact line array format. The Series includes the 3-way, bi-amplifiedCAF730 full-range and the complementary dual 12 in SS730 subwoofer.
4. CAF730 ARRAY DESIGN 4.1 CAF730 WIZARD Use the CAF730 Wizard for designing CAF730 arrays. It can be found in the Downloads/Software section of the woodworxmax website . 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 CAF730 array, the SS730 s should be the uppermost enclosures in the array. In this application, the SS730s are suspended flat-fronted, with the CAF730s suspended below in the curvature determined by the CAF730 Wizard. When flown separately, SS730s should be flown so that the spacing between the line of SS730 enclosures and CAF730 enclosures is about 1 ft /0.3 m. The SS730 should be suspended in a flatfronted configuration. 4.4.
5. ARRAY OPERATION 5.1 OVERVIEW The operation of a CAF730 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 CAF730 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 woodworxmax for the CAF730 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 CAF730 Wizard.
The following tables list the rms voltage limits for theCAF730 and SS730. Because of their higher impedance design, multiple CAF730s and SS730s ca n 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 CAF730 and SS730 loudspeakers.
5.7.3 Selecting an Appropriate Amplifier Size Rule Of Thumb If a CAF730 Line Array is used for professionally opera ted 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, woodworxmax 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 SS730 Connections There are three Neutrik NL4MP and one NL8MP connectors on the rear of each SS730. The connectors mate, respectively, with Neutrik NL4FC and NL8FC in-line cable connectors. SUB INPUT/OUTPUT NL4MP (each of two) PIN 1- SS730 SUB 1PIN 1+ SS730 SUB 1+ PIN 2- SS730 SUB 2PIN 2+ SS730 SUB 2+ 1. Use as the input to the SS730. 2. Use the second connector to loop SUB signals to additional SS730s. 5.8.
LF 5.8.4 CAF730P Input Connections There are two 4-terminal barrier strip connectors on the rear of each CAF730P. The connectors are wired in parallel so that the second connector can be used to loop LF and MF/HF signals to additionalCAF730s. The connectors accept stripped wire ends or wire lugs. 5.8.5 SS730P Input Connections There are two 4-terminal barrier strip connectors on the rear of each SS730P.
6. RIGGING CAF730 Series arrays are intended to be suspended or ground-stacked. This chapter details how to physically configure CAF730 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. CAF730 and SS730:The procedures to suspend and ground-stack CAF730s and SS730s are detailed in this chapter.
For a given quantity of SS730: Max quantity CAF730 = 18 - (1.5 x quantity SS730) Example, given five SS730: 18 - (1.5 x 5) = 10.5 which rounds down to a maximum quantity 10 CAF730s For a given quantity of CAF730: Maximum quantity SS730 = (18 - quantity CAF730) / 1.5 Example, given eight CAF730: (18 - 8) / 1.5 = 6.667 which rounds down to maximum quantity 6 SS730s 6.
6.4.3 Quick Release Pins Each CAF730 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 SS730 is supplied with four 1.5 inch Quick Release Pins used for attaching enclosures together or to the Fly-Bar. 6.4.
CAF730 FLY-BAR HINGE TUBE HOLES DANGER: Each Hinge Tube on the Fly-Bar has two Quick Release Pin holes. When suspending CAF730 or SS730s 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 CAF730 Face Pallet The CAF730 Face Pallet is a wheeled pallet that holds twoCAF730s 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 CAF730s and SS730s 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 CAF730 enclos ures be attached to an array one at a time. The SS730 enclosures may be attached two at a time. IMPORTANT NOTE: Always suspend all SS730s over the CAF730s. In all cases, reverse each procedure for unrigging the array.
6.7.4 Attaching SS730s to SS730s Already Suspended NOTE: SS730s should always be flown tight-packed to each other. 1. Move an SS730 Pallet so its SS730 is positi oned under the bottom SS730 of the array. 2. Remove the four Quick Release Pins from the Hinges of the SS730 on the pallet. 3. Lower the array until the bottom SS730 barely touches the SS730 on the Pallet. 4. Slide the four Hinges of the SS730 on the pallet into the suspended SS730’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 CAF730 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 CAF730, rotating it on the attached rear Hinges. 9.
6.8.2 Stacking Additional Enclosures (SS730 as the base) CAUTION: When attaching Hinges to Hinge Tubes in step 5 for an SS730, position the SS730 so it lies flat on the SS730 below it. In step 5 for a CAF730, use the correct holes as determined by the CAF730 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 SS730, position the SS730 so it lies flat on the SS730 below it. In step 5 for a CAF730, use the correct holes as determined by the CAF730 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.
