Ground Stackable Line Array System

The active 4-way COBRA-4 PH 5 SYSTEM is designed to project over distances of up to 80 metres in medium-sized marquees, halls and open-air venues and produces SPLs at the FOH position, 30 metres from the stage, of 110 dB in the medium-and high-frequency ranges and up to 120 dB in the bass.

Through the use of two COBRA-4 TOPs and a COBRA-4 FAR, optimal line-array performance can be achieved without timeconsuming tinkering. With the COBRA-4 SYSTEM, in the vicinity of the PA, the vertical coverage angle in the high frequency range is particularly wide, to cover the areas directly in front of the stage.

To project over long distances,a COBRA-4 FAR, which has a coverage pattern of 90° x 5° in the high frequency range, is positioned at the top of the array. For the low frequency range and the midrange, the same components are used as in the COBRA-4 TOP, so the low and midrange line array continues in an unbroken line.

In all, eight COBRA PWH bass horns are used to generate the sound pressure levels and projection typically required by touring bands and these can be stacked or arrayed as dictated by the architecture of the room.

The COBRA-4 PH 5 SYSTEM is driven by a ready cabled and programmed CSR-H45 amp rack. CSR-H45 has one additional amplifier for a more powerful and dynamic transmission of LF.LF amplifier feeds an additional loaded only two subwoofer and run on 4 ohm load, unlike CSR-H42, wherein one channel of the amplifier is loaded by the subwoofer, with 2 ohm load. This configuration of the rack is suitable for permanent installation in dance clubs, where the transmission of low frequency range and operating time amplification system are increased requirements.

All equipment is installed in a secure rack case on wheels height of 18 U which includes:

• 1 x R-14 Rack
