OVERVIEW

EVO88 System is a multipurpose line-array system that can serve as a portable or installed FOH solution for medium to large venues and as ancillary side/down fill for larger PA systems, with a coherent, natural sound within the coverage area and superior power delivery in its category.

EVO88 System features an active EVO88-M line-array element that features a 1.2 kW Class-D Powersoft power module that feeds another passive EVO88-P element, integrating a straightforward active system that optimises costs, setup and logistics.

The HF assembly mounts a 3" compression driver and an IDEA proprietary Hi-Q waveguide allowing for minimum vertical gap between array elements providing optimum element coupling and reducing artifacts and DSP adjustments while providing optimum directivity control. For LMF section, EVO88 mount dual very high-performance 8" woofers.

Self-Powered solutions with EVO88-M

The active EVO88-M features a 1.2 kW Class-D amp and DSP power module by Powersoft so one EVO88-M element can power another EVO88-P in active system, as shown in the diagram below, with the dedicated SpeakON NL-4 cable links included with every EVO88-M.

Depending on the scale of the application, a medium-sized EVO88-M system can be easily split into smaller clusters for mobile and portable solutions.

Passive systems can be configured as factory ready with turn-key solutions for TEOd8 driven amps as well as top-tier third-party platforms (see www.ideaproaudio.com/evo88-p for preset availability).

Acoustical Measurements

Frequency Response

The frequency response graph displays dB SPL (Sound Pressure Level) on the Y-axis against Frequency (Hz) on the X-axis, ranging from 20 Hz to 20 kHz. The graph shows the response for a 1-watt swept sine signal in a semi-anechoic environment, measured at 3m and scaled down at 1m. A 1/12 octave smoothing has been applied to provide precise information for acoustical analysis. The response generally remains flat across the mid-range, with some variations at lower and higher frequencies.

Impedance

The impedance graph illustrates Ohm (Ω) on the Y-axis against Frequency (Hz) on the X-axis, ranging from 20 Hz to 20 kHz. It shows the electrical impedance characteristics of the system across the frequency spectrum, indicating nominal impedance and variations at resonance points.

HORIZONTAL 1/3 Octave POLARS

This section presents six polar plots, each showing the horizontal directivity pattern of the EVO88 System at different 1/3 octave frequencies. The plots are arranged in a grid, covering frequency ranges such as 80-160 Hz, 200-400 Hz, 500-1000 Hz, 1.25-2.5 kHz, 3.15-6.3 kHz, and 8-16 kHz. Each plot uses concentric circles representing attenuation in dB (e.g., +12, 0, -12, -24, -36, -48 dB) and radial lines indicating angles from 0° to 180° and -0° to -180°. These diagrams visually represent how sound is dispersed horizontally at various frequencies, showing the system's coverage and off-axis response.

VERTICAL 1/3 Octave POLARS

This section presents six polar plots, similar in format to the horizontal plots, but illustrating the vertical directivity pattern of the EVO88 System at different 1/3 octave frequencies. The plots cover frequency ranges such as 80-160 Hz, 200-400 Hz, 500-1000 Hz, 1.25-2.5 kHz, 3.15-6.3 kHz, and 8-16 kHz. Each plot uses concentric circles representing attenuation in dB (e.g., +12, 0, -12, -24, -36, -48 dB) and radial lines indicating angles from 0° to 180° and -0° to -180°. These diagrams visually represent how sound is dispersed vertically at various frequencies, crucial for understanding array coupling and vertical coverage in line-array applications.
