Portable Array System Power Extension Set w / distance bar & speaker cable, 47 - 20000Hz, Amplifier Class D, black
Should an existing CURV 500 Entertainer Set need to be upgraded because, for example, more power is required in the bass range, the Power Extension Set is the right choice. The portable array system then turns into a Power Set. Visually aligned with the award-winning CURV 500 design, the Extension set includes an Extension Subwoofer, four array satellites, a SmartLink Adapter, a distance bar and speaker cable, but comes without a mixer. 300 watts RMS and 1200 watts peak for the bass reproduction provide for substantial punch in the bass range. The four satellites rely on a power amplifier with 160 watts RMS or 640 watts Peak. The Class D power amplifiers with switching power supply provide the necessary power.
The four satellites are operated via SmartLink adapters. The elements, only 12 x 12 cm in size, are equipped with LD System's own WaveAhead technology; one 4" and three 1" drivers provide a coherent and extremely detailed playback with high pressure and dynamics.
The 10-inch woofer resides in a black bass-reflex cabinet made of plywood. The 325 x 383 x 491 mm large cabinet with PA-protective coating weighs 16.5 kg and can be easily transported by means of three ergonomically shaped handles. In addition to a DSP-based multiband limiter, protection circuits prevent short-circuits, overheating or overloading and ensure safe operation. The humming noises caused by variations in the earthing potentials can be avoided with the ground lift function. The M20 threaded flange on the subwoofer gives a firm hold to the adjustable distnace bar and the locking mechanism secures the array satellites against unwanted turning. The system cabling is carried out with the five-pin XLR input; an additional subwoofer can also be connected to the five-pin XLR output socket.
