EAW makes additions around KF740
EAW has released the KF740 zero degree adapter accessory, which is intended to permit KF740 line array modules to hang with zero degrees of splay between adjacent modules, reportedly increasing the output and throw distance. In addition, the adapter’s design reportedly increases the total load-bearing capability of the upper modules, increasing the size of arrays that can be safely hung.
The new accessory allows the creation of an array with up to 24 flat-fronted modules at a safety factor of 10:1. According to the manufacturer, such an array would offer up to 152m of throw, reportedly generating over 105dB at that distance. Much larger arrays are possible at a 5:1 safety factor.
The new adapter accessory is made from 7075-T6 and 6061-T6 aluminium and the manufacturer states it can carry well over 45,000kg. Each adapter can carry 544kg at a safety factor of 10:1. Adapters attach to the loudspeakers with custom-designed, 17-4 PH H900 stainless steel shank, quick release pins tethered to the accessory with wire lanyards.
EAW states that load-bearing requirements change with the specific configuration of a given array, and that users should always generate array designs using EAW Resolution array design and modelling software.
A further addition to the manufacturer’s line is the Powercube amp racks, which have reportedly been optimised for use with KF740 line arrays and the largest EAW subwoofer systems, as well as KF760 or KF730 systems. Each Powercube amplifier rack includes electrical power distribution, 12 channels of amplifier power with integrated digital signal processing and 12-channels of input and output.
Powercubes support either three Lab.gruppen PLM20000Q/SPs or six Powersoft K10 DSP+AESOP amplifiers. Amps are shipped separately from the respective manufacturers for user installation on delivery. Powercubes come in 115V and 230V options, making four options in total. Electrical power distribution panels are separately configured for each of the four possible options.
Powercubes feature a 24U rack in a shock-absorbing cage to house the power distribution, amplifiers and input and output panels. Electrical power distribution panels include standard, three-phase input connectors and circuit breaker protected outputs configured to support each amplifier compliment.
The input panels provide analogue connections with loop through, AES connections with parallel loop through and dual Ethernet ports for loop through the amplifier’s digital network. Selectable ground lifts located on each analogue input allow it to be linked to the next successive input in series, allowing a single input to drive multiple channels of a multi-amp system. Likewise, Powercube output panels feature both Neutrik NL4 and NL8 connectors.
Powercube purchasers are entitled to sign up for EAW’s Red Certification training programme. This is awarded after a two-day training seminar held at the customer’s offices. Red Certification ensures that all Powercube owners and their staff are fully trained on all aspects of using the power and processing available through the Powercube.
