Palco Plus kan brukes til alt fra klubber til de største utendørs konserter.

The heart of the PalcoPlus system is the two-way, line-source element RA16. This compact enclosure offers 1000 W of applicable continuous power per unit, in a package approximately the same size of a 6U outboard rack case. Whereas most modern line array elements of these dimensions use 6.5″ woofers, the RA16 employs two 8″, purpose-built woofers with 2.5″ voice coils, utilizing neodymium magnets.
The high frequency section consists of a single custom-built compression driver with a titanium diaphragm, a 3″ voice coil and 1.4″ throat. The driver is coupled to an aluminum planar waveguide with its exit between the baffles of the two woofers, which are precisely angled to accompany the natural dispersion of the waveguide. The entire forward section of the enclosure, in fact, behaves as a horn above a certain frequency. Precisely tooled from birch plywood, this external waveguide serves to couple the outputs of adjacent elements into the cylindrical wavefronts characteristic to a line-source array.
An array of four RA16s exhibits precise 120• horizontal dispersion with a frequency response of 70 Hz — 20 kHz (–3 dB).
While most line array elements cannot be used effectively in very small numbers, the RA16´s design permits use of even only two elements clustered for small applications, though in this configuration it behaves not as a linear source, but as a highly directive point source cluster.
Each unit can develop a maximum SPL of 130 dB, thus providing ample power and coverage even in small numbers.
The cabinet is constructed entirely of 15 mm birch plywood finished with high-impact, chip-resistant paint. The coupling hardware is fully incorporated, and is made of aircraft-grade, nickel-chromium-molybdenum steel. The splay angle from one element to another is adjustable from 0• to 12•. The light weight of the enclosure and the clever system of coupling and splay angle adjustment permit the assembly of arrays with only two hands available.

 

One Montarbo PLM6800 can drive an array of four RA16 enclosures, otherwise each RA16 can be driven by a power amplifier that can deliver at least 800 W at 8 ohms for the woofers and 200 W at 16 ohms for the driver.
A two channel amplifier capable of furnishing 1600 watts at 4 ohms per channel is suitable for driving two speakers.

 

Each RA16 line-array enclosure is supplied with:
* 2 rear steel plates that allow the assembly of the enclosures in the array and for adjusting the vertical splay angle between units.
* 6 highly resistant quick release pins (figure 7 – B) with ball safety lock (3/8″ x 1/2″).

RAB1815 subwoofer is designed to extend the frequency range of the PalcoPlus system down to 30 Hz. This innovative sub-bass unit offers a distinctive, dual-transducer configuration using one 18″ woofer in a ported reflex configuration, and a second, 15″ woofer loaded by a folded horn. The precise interaction of these two transducers permits the RAB1815 to radiate in a cardioid pattern from a single enclosure, with 15 dB attenuation at 180• from 40 Hz to 100 Hz, allowing much more bass reinforcement to be used for the public, even very close to the stage. Aside from creating a unidirectional polar characteristic, this design also provides the benefits of both bass reflex and folded horn systems: very deep bass, but with rapid response. The design also puts the actual cone movement of the two speakers in opposition on the same axis of the enclosure, assuring that the sub will not move. The two transducers are purpose-built for the RAB1815. They are constructed with neodymium magnets and 4″ voice coils, and can boast an excursion of –23 mm. Both woofers can handle upto 1600 W of continuous power, and the entire system is capable of delivering 136 dB SPL.
The cabinet is made of 18-21 mm birch plywood with chip-resistant paint. The RAB1815 weighs less than 60 kg, and is built to act as a base for stacked arrays of RA16 enclosures.
A single Neutrik 8-pole Speakon® connector provides simple and intuitive connection to the powered controller PLM6800 or to any other power amplifier, and helps to avoid mistaken connection to channels destined to the satellites during cabling.
A single PLM6800 can drive two RAB1815 units, otherwise each RAB1815 can be driven by a two channel amplifier with a rated output of at least 1600 watts per channel at 4 ohms.
