AUDIOFOCUS EVO, EVO8a, EVO10a, EVO15a, EVOSub15a User Manual

EVO(a) series user’s manual

Introduction

Thank you for purchasing AudioFocus©. That product is designed and made in Belgium with the highest quality
control and reliability. We hope you’ll be fully satisfied by this device.

EVO(a) serial has been designed for small to middle fixed or touring applications. Our main philosophy is that each
model is available in active or passive version. This manual is made for both versions and is divided in three
subsections: active, passive, and a third section for EVOSubXXa-flex.

Thanks again and good reading, AF team

What’s the difference between EVO and AudioFocus competitors?

- Special EQ

The EVOa integrates more HiFi dynamic features. At the same time, EVOa has flat response for several presets. We
worked very hard on the ‘’extended’’ preset to give possibility to use the EVOa tops without any subs. We use our
own DSP technologies to achieve that point of schedule and reach very high spl and low cutoff frequencies.

- New AudioFocus transducers

The other main difference is that we designed our own transducers with very precise electro-mechanicals
parameters to reach the best stability as possible, and have low distortions and very good transient response in small
cabinets. These loudspeakers have been developed with state of the art companies such as Ciare, Sica or Faitalpro to
achieve high quality transducers you can only find in AudioFocus’ EVO(a) range.

- Wedge/monitor application

The EVO top models can be used for front stage or as wedge (mirror configuration) as described here below:

In asymetrical configuration, the difference of path between acoustical sources and singer may occur in audio
confusions. In symetrical configuration the there’s no delay between the two cabinets. Image of the sound is better
and more precise.

- Included Tiltable flange in the top units - Included M20/35mm flange in the sub units

- Full compatibility with Powerdrive accessories (see accessories section of this manual)

- M8 internal inserts for maximum security

Mainly the result of the EVO(a) range is a good summary of the knowledge of AudioFocus’s team since 1998 taking

care of market’s request, customer’s feedback and competitor’s products.

Before starting the system, the user must read the safety instructions present at the end of this manual.

1. Volume control from -∞ to +6dBu.

2. Diagnosis and status Leds.

3. Balanced output XLR connector (male, 2+, 3-, 1GND).

4. Preset selection switch.

5. IN main power supply connector (powercon)

6. OUT main power supply connectors (powercon)

7. Balanced input XLR connector (female, 2+, 3-, 1GND).

This connector is parallel wired with the input (3) to link some cabinets together.

8. Preset status leds.

1. The main voltage must be ALWAYS earthed to protect user in case of
current losses or bad insulation.

2. ALWAYS replace the fuse with the same type and value (T3.15A/240V).

3. Make sure that the power switch is set to “OFF” before you connect the devices

4. A good cable improves the sound quality. Input cables should be as short as
possible.

5. If long signal cables are necessary, you should use balanced cables.

1. Active version (EVO8a, EVO10a, EVO12a, EVO15a, EVOSub15a, EVOSub18a)

These models receive two ways digital high efficiency amplifiers. These ‘’green’’ energy amplifiers
includes 4 presets for most of the applications we can meet on pro audio field.
Here’s a description of the rear panel of Subs and Tops units:

Diagnosis and status Leds

Limit: ON when output signal is @-3dBspl of the peak.

Temp: ON when working temperature is too high. The electronics get in protection

(attenuation of signal, and stop if temperature still increases). In case of working in hard
temperature conditions (front of the sun), we invite the user to use our cover to protect the
amplifier against any over-heating problem.

Signal: ON when a signal is detected at the input of the cabinet.

Ready: ON after a few seconds, the system is ready for use.

Preset explanations

User has the choice between 4 built-in presets to make the system plug and play. The preset select switch (4)
permits to the user to choose the best preset for his application.

Top units (EVO8a, EVO10a, EVO12a, EVO15a)

Full range : Flat response when the top unit is used alone on a stand.

Extended : A correction is applied on the LF transducer to extend the low

frequency reproduction when the top unit is used alone (without sub).

HPF : Use that preset if the top unit is coupled to a subwoofer.
The top only deliver frequencies from 100Hz to 20kHz.

Monitor : The cabinet deliver a flat signal when placed on the floor. That preset is
made for wedge applications.

Sub units (EVOSub15a, EVOSub18a)

Extended : For subwoofer applications with lower cutoff frequency.

Kick : For bass application with a +3dBspl correction around 70-80Hz.

100Hz : Low pass cutoff frequency is 100Hz, 24dB/octave.

80Hz : Low pass cutoff frequency is 80Hz, 24dB/octave.

Remarks

1. Depending of the Sub/Top ratio, levels of each cabinet must be adjusted to reach the optimal sound result of

the setup.

2. Always use HPF preset for Top units when coupled to a subwoofer.

3. Spl curves are available on request.
