INTRODUCTION

This manual is designed to help GTA 2X8 L.A. system users from Pro DG Systems, to the correct use and for the understanding of the benefits and versatilities of the same. GTA 2X8 L.A. is a line array system completely designed, manufactured and optimized in Europe (Spain}, exclusively with European components.

GTA 2X8 L.A.
100% designed-fabricated-optimized in Europe (Spain) only and exclusively with European components.

DESCRIPTION
Self-powered line array system of 2-ways, equipped with two (2) speakers of 8″ in a tunning enclosure. The HF section has two (2) compression drivers of 1″ coupled to a wave guide. The transducer configuration generates a symmetric and horizontal dispersion of 120 degrees without secondary lobes over the entire frequency range. Ideal for main P.A. Frontfill, Sidefill and Downfill both in outdoor events as well in permanent installation.

SPECIFICATIONS

ARCHITECTURAL SPECIFICATIONS

Inside the GTA 2X8 L.A. is composed by two (2) Beyma speakers of 8″, 300 W RMS. Specially designed under our own parameters for the best performance of the system.

KEY FEATURES

• Excellent power and performance
• Extended controlled displacement: Xmax ± 6 mm
• Extended mechanical displacement capability
• Designed with MMSS technology for high control, symmetry and linearity with ferrite magnet
• Demodulating ring for low harmonic distortion
• CONEX spider for higher resistance and consistency
• Waterproof carbon fiber loaded paper cone with Santoprene™ surround

TECHNICAL SPECIF/CATIONS

**THIELE-SMALL PARAMETERS***

Specially designed under our own parameters for the best performance of the system.

MOUNTING INFORMATION

The X max is calculated as; (Lvc-Ha)/ 2 +(Hag/ 3,5), where Lvc, is the voice coil length and Hag is the air gap eight.

INSIDE THE GTA 2XB L.A.

GTA 2X8 L.A. is also composed by one block which together with two (2) compression drivers, constitute the constant directivity horn, specifically designed to work with two (2) Pro DG Systems compression drivers of 50W RMS coupled to a waveguide.

The constant directivity characteristics of this model ensure the ability to cover 120° wide horizontally and 20° wide vertically at virtually any frequency within its operational range. To ensure freedom of resonance is constructed of aluminium with flat front finish to facilitate flush mounting.

KEY FEATURES

• Designed to be used with two Pro DG Systems compression drivers of 50 W RMS to a waveguide
• Provides uniform response
• Coverage of 120° in the horizontal plane and 20° in the vertical plane
• Precise directivity control in the pass band
• Aluminium construction with flat front to facilitate flush mounting

TECHNICAL SPECIFICATIONS

GTA 2X8 L.A. is also composed by two (2) Beyma compression drivers of 50 W RMS, coupled to a waveguide. Specially designed under our own parameters for the best performance of the system.
A combination of high-power neodymium compression driver with waveguide provides the best junction for the best efficiency of GTA 2X8 L.A. Solving the hard problem of achieving an optimum coupling between adjacent high-frequency transducers. Instead of using expensive and troublesome wave-shaping devices, a simple but effective waveguide transforms the circular aperture of the compression driver into a rectangular surface, without undue angle aperture to provide low curvature to the acoustic wavefront, arriving to fulfil the necessary curvature requirement for the optimal acoustic coupling joint between adjacent sources until 18 KHz. This is achieved, with the minimum possible length for low distortion, but without being excessively short, which would cause strong high-frequency interferences.

KEY FEATURES ( ONEUNIT)

• 4″ x 0.5″ rectangular exit
• Neodymium magnetic circuit for high efficiency.
• Effective acoustical coupling up to 18 kHz.
• True 105 dB sensitivity 1 w@ 1 m (averaged 1-7 kHz).
