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. 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.
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.

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.

Examples of configurations
In these examples you can consider all EVO tops and EVOsubs models.
Always use HPF preset for Top units when coupled to a subwoofer.

2. Passive version (EVO8, EVO10, EVO12, EVO15, EVOSub15, EVOSub18)
When linking identical speakers together (in parallel), the resulting impedance is divided by the quantity of speakers. The
user must ALWAYS take care about this resulting impedance, and the minimum impedance allowed by the amplifier
1 : Rear serigraphic.
2 : Neutrik Speakon input/output connectors

Examples of configurations
Top units alone:
Top + Sub configuration
In that case, one amplifier is used for the Top units and another one for the Sub units. Filtering between Top and Sub
will be made by an ADSP26 AudioFocus© processor or any active X-over. The best way to achieve optimal audio
result is to use ADSP26 AudioFocus© processor that includes the needed presets for your configuration.
-ADSP26 processor is available with integrated presets for all our range. These presets can be recorded in the ADSP26
on demand. If not, our technical staff can send these by email.
-Compressor/limiter functions are integrated in ADSP26. Due to the fact that user can use several kinds of amplifiers, we
cannot calibrate ADSP26’s limiter. The user must do it by him-self taking care of the power handling of AudioFocus’s
cabinet, and the amplifiers’ power.

3. Active Sub with auxiliary power outputs (EVOSub15a-Flex, EVOSub18a-Flex)
The best way to have a compact ‘’plug and play’’ system is EVOSubXXa -Flex. It has exactly the same features than
the EVOSubXXa, except that the amplifier module is a double one. So, EVOSubXXa -Flex includes auxiliary power
outputs for Top units.
To ensure a good Top/Subwoofer ratio, SLSubXXa-Flex has 4 presets. That permits coupling EVOSubXXa -Flex with
high, middle and low sensitivity Top units.
Rear connection description
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. Left input.
2. Right input.
3. Left output.
(190Wrms/8ohms; 350Wrms/4ohms)
4. Right output.
(190Wrms/8ohms; 350Wrms/4ohms)
5. Bridge output (600Wrms/8ohms).

Examples of configurations
- Never use stereo outputs and bridge output at the same time.
- Always respect minimum impedance (4ohms for stereo outputs, 8ohms for the bridge output).
- Coupling with other EVOSubXXa (normal active version) is possible. In that case, user must configure EVOSubXXa in
Extended preset.
- Always consider the power capabilities of the top units wired to the EVOSubXXa -Flex subwoofer.
