JBL IVX-587060 Professional Speaker

JBL IVX-587060 Professional Speaker

The unit will consist of a line array configuration comprising sixteen 4" full-range loudspeakers, each equipped with moisture-resistant diaphragms. The arrangement of the individual loudspeakers will follow a patented scheme. To minimize external connections and associated costs, all signal processing functions required to drive the directivity-controlled line array with electronic aiming properties will be integrated onboard. The electronic components will be housed within a separate compartment at the front of the enclosure, mounted on a chassis. The electronics package will include an audio input module, a two-input/eight-output channel DSP section, eight power amplifiers with protection circuitry (with amplifiers one through four driving one loudspeaker each, and amplifiers five through eight driving three loudspeakers each), and a switched-mode power supply. The input section will be transformer-balanced. Array signal processing will be handled in the digital domain by a 900MFLOPS 32-bit DSP, which will implement output channel filters and delays. Additionally, the DSP will provide EQ, pre-delay, volume and autogain, and compression functionalities as required. The DSP software and coefficients will be stored in non-volatile memory to allow for adaptations and software updates.

The control unit shall be equipped with a fully isolated RS-485 based full-duplex serial network interface. This control unit shall serve three main functions:

• Remote monitoring of parameters like status of the DSP, amplifiers and loads, external pilot tone, status of the ambient noise sensing microphone, chassis temperature, ambient noise level, ambient temperature, control for the input section etc.
• Remote control of beam parameters, volume and analog pre-gain, pre-delay, EQ, autogain configuration and surveillance related parameters.
• Updating DSP software and factory unit programming.

The audio signal shall be connected to a 6p male 5 mm pitch cage clamp connector (as WAGO series 231). The RS-485 signal shall be connected to a 5p cage clamp connector of the same type as specified above. The unit shall be equipped with a 3p male IEC mains supply connector. All connectors shall be grouped together on the electronics chassis and shall be accessible from the front and the rear of the unit. The enclosure shall be constructed of steel finished with an epoxy coating. At the back side of the enclosure a total of two bracket attachment points shall be provided (located near the outer ends). The protective front shall consist of a perforated steel grill which can be clicked onto six snap-in studs mounted on the enclosure.

The complete loudspeaker unit shall meet the following criteria:

Typical frequency range of the complete array 130 - 10k Hz on axis (+/- 3 dB), max. SPL at 30 m of 92 dBSPLcontinuous and 95 dBSPL peak, adjustable vertical beam shape is defined by the DDS (Digital Directivity Synthesis) algorithm, fixed horizontal opening angle of 130° (-6 dB, averaged 1k to 4k Hz).
