Voltage selection

EVO20-M’s integrated power module features two different Mains Input selectors to operate at 240 V and 115 V.
Although all EVO20-M systems are served ready to operate at the right voltage of the region it is shipped to from the factory, when setting up a system for the first time, we strongly recommend to check if the power module Mains connector matches your AC power supply voltage.
To do so, it is only required to remove the heat sink screws and check which position the Mains Input is connected to, as shown in the diagram.

System Configurations

Introductory guidelines on Line-Array system configurations
Line-Arrays work because of the interactions of the different transducers in each array element. Some of these interactions result in negative effects, such as distortion and phase is-sues, the benefits of energy summing and a degree of vertical directivity control prevail as the advantages of using Line-Array systems.
The IDEA DSP Line-Array settings aim to facilitate a simplified approach to the Line- Array setup and deployment and focus on two fundamental factors that affect the behavior of the array in terms of directivity and frequency response linearity.

Array Length
The first factor is Array Length, which influences the range of frequencies in which the linearity of the response of the array is affected by the total distance between the axis of all the trans-ducers aligned in the vertical plane.
This is specially noticeable in the LF, as the LF woofers, due to their proximity in relation the their band pass, sum acoustic energy particularly efficiently, and require a compensation of the amplitude of the LF signal from the crossover point with the subwoofers up to different frequency points depending on the number of elements present in the array.
For this purpose the Settings are grouped in four Array lengths/Element counts: 4 -6, 6-8, 8-12 and 12-16.

Array Curvature
The second key element for the DSP setting of the Arrays is the curvature of the array. Many different combination of angles can be set by the operators of a Line-Array, optimizing the desired vertical coverage required for the application.
Users can use EASE FOCUS as a guide to find the ideal internal splay angles between array elements.
Note that the sum of the internal splay angles and the nominal vertical coverage angles of the array do not correlate directly and their relation varies with the array length. (see examples)

IDEA DSP settings
IDEA DSP settings operate in 3 categories of averaged Array curvature:

MINIMUM (<30° Recommended Internal Splay Angulation Sum)
MEDIUM (30-60° Recommended Internal Splay Angulation Sum)

MAXIMUM (>60° Recommended Internal Splay Angulation Sum)

EASE FOCUS Prediction Software
EVO20-M Ease Focus GLL files are available for download from the product’s page as well as from the Downloads repository section.

MINIMUM ARRAY CURVATURE

<30° Recommended Internal Splay Angulation Sum
Low internal splay angles result in more “straight” arrays that concentrate more HF energy on the acoustical axis of the Array, achieving greater HF energy over greater distances (improving “throw”) but narrowing down the usable vertical coverage.

These settings are available for TEOd9 and other External Stan-dalone DSP processors for IDEA Active Line-Array systems like EVO20-M, and included in IDEA System-Amplifier DSP Solutions.

MEDIUM ARRAY CURVATURE

30°- 60° Recommended Internal Splay Angulation Sum
This is the most useful level of vertical coverage for the most typical flown Line-Array applications and it will ensure balanced coverage and SPL within the listening area for the majority of the applications.

These presets are found as standard in the EVO20-M integrated DSP and can be directly selected from the back pannel interface as shown in Section of this document.

MAXIMUM ARRAY CURVATURE

60° Recommended Internal Splay Angulation Sum
Larger internal splay angle counts result in greater curvatures, with wider vertical coverage patterns and lesser summing of the HF energy. This kind of angling is found in Arrays with a small box count or in larger arrays that are ground-stacked or installed close to grandstands in Sport arenas.
These settings are available for TEOd9 and other External Stan-dalone DSP processors for IDEA Active Line-Array systems like EVO20-M, and included in IDEA System-Amplifier DSP Solutions.

Rigging And Installation

EVO20-M Line-Array elements feature an integrated steel rigging hardware especially designed for ease of set-up and use. Up to 10 internal angulation options in 1° steps are available and dedicated stow positions for a precise and quick deployment of the array.
The following are the basics for array element linking.

BASIC GUIDELINES

To proceed setting-up the array, release and unlock the front and back links of the lowest element in the system.
Position and lock the front and back links of the following element in the array using the spare pins stored in the dedicated hole labelled as Stow.
Finally lock the desired position with the dedicated pin stored in the Groundstack/Stow hole. Repeat the operation for the any other EVO20-M element in the system.
