EVOi.net
DESIGN OVERVIEW
The EVOi.net is either supplied in a 19” rack mount
configuration or as part of the EVOi.sys.
Simplicity in the presentation is at the forefront of the
EVOi.net design. For installed loudspeaker systems, it is
not practical to initiate setup and operational function with
control on the actual loudspeakers. Therefore the EVOi.net
simply provides a more convenient remote control of the
functions in the EVO Intelligent Loudspeaker Systems.
The control is presented in two sections: one for installation
and setup; the other for operation. The functions are
initiated with simple button pushes and responses annunciated with colored indicators (LEDs). The hook-up is
enabled with standard signal cable and XLR connectors.
Due to the nature of the technology, no other network
cables are required to communicate button pushes to the
EVO Loudspeakers.

1 INPUT Indicators
Two sets of LED indicators monitor audio signal levels at
the inputs A (left) and B (right). When the green SIGNAL
indicators are on, the input signals are greater than -40 dB.
Below this threshold, the indicators will be off, signifying
that the input signals are too low for proper amplification or
are disconnected from the system.
When the red CLIP indicators are on, audio signal levels
are 2 dB below the maximum clip level. If the input signals
exceed this level, distortion will result. When you observe
this condition, simply lower the L MIX R (Master)
Faders until the CLIP indicators turn off.
2 SPEAKER STATUS Indicators
Two sets of LED indicators, OKAY and WARNING,
provide visual status of amplified signal levels driving
EVO loudspeakers connected to the main outputs, 1A (left)
and 2B (right), and the auxiliary outputs, 3A (left) and 4B
(right). The indicator states are:

Installation Notes
Although installing an EVOi.net is straightforward, please
review the following notes to achieve the best installation:
• Choose a mounting location that provides direct front
panel viewing and easy access to the controls.
• The EVOi.net does not have a power on/off switch and
therefore is “ON” whenever AC power is activated. If
desired, use switched power outlets for master system
control.
• We strongly recommend the use of high-quality,
shielded audio cables for connection to the mixer and
EVO loudspeakers.

INSTALLATIONS/SETUP
USING THE AUTO EQ SETTING
Placing Measurement Microphone
for MAIN EVO Loudspeakers
For simple applications of up to two EVO loudspeakers
hooked up to OUTPUTS 1A and 2B (the MAIN OUT
outputs), optimum placement of the Measurement Microphone is illustrated in Figure 10.
1X2X3X
The placement follows a simple height-to-depth ratio of
1:2. For a given loudspeaker height the optimum position is
a distance twice the height away from it, into the listener
area. For instance, if the speaker is 10’ in the air, measure
20’ into the listening area and place the microphone there.
It is very important that the Measurement Microphone
remains on the central axis of the room or listener area,
equidistant from each loudspeaker. See Figures 11 a, b, c.
A rough rule of thumb is that the Measurement Microphone
should remain equidistant from both loudspeakers at a point
approximately 2/3
from the loudspeakers.
For optimum result please also make note of the type of
floor in the listening area and follow the guide below in
Figures 12a and 12b.

INSTALLATIONS/SETUP
Performing Auto EQ for MAIN OUT
Loudspeakers
Before starting, check that the LOCKED indicator is off. If
it is on, then use the rear panel switch (Feature 14 page 6)
to enable Auto EQ buttons.
1. Press the round MAIN OUT SETUP 1&2 button
(Figure 13). On release, the LED flashes, and the Auto
EQ routine begins.
2. The EVO loudspeaker connected to MAIN OUTPUT
1A is instructed to Auto EQ and generates its own test
signal. This lasts for a few seconds. It is recommended
that during the test signal, background noise is kept to a
minimum. It takes about 40 seconds after the test signal
for the EVO loudspeaker’s built-in computer to adjust
and acoustically optimize itself to its environment.
3. Once set, an instruction is automatically sent to the
EVO loudspeaker connected to MAIN OUTPUT 2B.
If an EVO loudspeaker is connected, then it also
performs its own Auto EQ routine. If an EVO loudspeaker is not connected or when the EVO loudspeaker
connected to MAIN OUTPUT 2B has completed its
Auto EQ routine, the EQ SET indicator will light.
4. At the same instant EQ SET lights up, AEQ ON also
illuminates indicating that Auto EQ is on.
Testing Auto EQ
1. Pass program signal to EVOi.net and listen to the result
of Auto EQ.
2. Press the AUTO EQ button (the LED will illuminate
when Auto EQ is active) and listen to the ‘Before &
After’ Auto EQ.

3. If the result of Auto EQ is desirable then continue, if
not then:
i. Check the position and aim of the EVO loud-
speakers, CLEAR AUTO EQ (see below) and
repeat the Auto EQ routine.
ii. The Measurement Microphone may not be
located in a position that strongly reflects the
natural acoustics of the room. CLEAR AUTO
EQ (see below), move the Measurement
Microphone a few feet and repeat the Auto EQ
routine.
Pressing any button during the Auto EQ routine will
abort the process and settings will return to their previous
values.
If an error is detected during the Auto EQ routine, this will
be shown on the SPEAKER STATUS indicators and an
attempt will be made to restore any Auto EQ settings to
their previous values.
Clear Auto EQ
Press the round MAIN OUT SETUP 1&2 button again and
the Auto EQ routine will run again. Previous Auto EQ
settings do not have to be cleared first.
Press-and-hold this button and all of the previous Auto EQ
settings will clear and the EQ SET INDICATOR will go
out as will the AEQ ON INDICATOR.

Ideal placement of the Measurement Microphone is again
determined by following the simple height-to-depth ratio of
1:2, where, for a given loudspeaker height the optimum
position is a distance twice the height away from it, into the
listener area. It is still crucial that the Measurement
Microphone remains on the central axis of the room or

INSTALLATIONS/SETUP
DELAY SETTING
EVO Loudspeakers hooked up to AUX OUT 3A & 4B
outputs can be instructed to automatically set their correct
delay and level to perform optimally with EVO Loudspeakers hooked up to MAIN OUT 1A & 2B outputs. A Haas
delay will also be added to the AUX OUT Loudspeakers to
make sure the MAIN OUT Loudspeakers are the acoustic
focus. Before starting, check that the LOCKED indicator is
off. If it is on, then use the rear panel switch (Feature 14,
page 6) to enable the DELAY SET button.
1. Position the Measurement Microphone in the optimum
position. This is located equidistant from each AUX
(delay) EVO Loudspeaker (in most cases on the central
axis of the listening area), approximately 10 feet away.
10'
Figure 18: Measurement Mic Placement for Setting Delay
2. Press the round delay SETUP button. When the button
is released the SETUP indicator flashes and the EVO
Loudspeakers hooked up to the MAIN OUT outputs
emit a test signal. Then the EVO Loudspeakers hooked
up to the AUX OUT outputs emit a test signal.
Pressing any button during the Delay Setting routine will
abort the process and settings will return to previous
values.
If an error is detected during the Delay Setting routine, this
will be shown on the SPEAKER STATUS indicators, and
an attempt will be made to restore any Delay settings to
their previous values.
Clear Delay Setting
Press the round DELAY SET button again and the Delay
Setting routine will run again. Previous Delay Settings do
not have to be cleared first.
Press-and-hold this button and all previous Delay settings
will clear and the DELAY SET indicator will go out.
Locking the Settings
After each SETTING routine, the LOCKED indicator will
flash once to remind you that this setting can be locked.
Once the desired SETTINGS routines have been performed and all are satisfactory, they can be “locked in” as
the default or NEUTRAL system settings.
1. On the rear panel, use a pin or matchstick to engage the
LOCKOUT SWITCH (Feature 14, page 6).
2. Once engaged, the LOCKED indicator will illuminate
continuously.
3. All SETTING buttons will now be disabled until the
Lockout Switch is disengaged.
3. When the correct delay and level for the AUX EVO
Loudspeaker/s have been set the DELAY SET
indicator illuminates.

ANTI FEEDBACK CONTROL
Two different types of Anti Feedback Control engines can
be initiated and set up via EVOi.net: Live Anti Feedback
Control and Fixed Anti Feedback Control.
Live Anti Feedback Control is designed to be used during
a performance. Once initiated, six dynamic filters are set
into action, instructed to search for and eliminate feedback
once found. When feedback is detected, a filter is placed to
eliminate it before it “runs away”. If additional feedback is
found, another filter is used. The FILTERS FREE
indicators tell you how many of the six filters are left.
Fixed Anti Feedback Control is designed to eliminate
feedback before a performance begins, a routine possibly
done during a soundcheck. For a fixed stage setup of
microphones, once initiated, six filters are available to
eliminate feedback. The FILTERS FREE indicators also
tell you how many filters have been used.
Note: There should be no feedback with a correctly set up
and operated sound reinforcement system. The general idea
of the FILTERS FREE indicators is as a guide to the
operator. If all the Anti Feedback Filters have been used,
this is a strong indication that the whole system needs
adjustment. Typically this is confined to the mix.

continue to eliminate feedback, reassigning the oldest or
first placed filter to the newest feedback frequency. This
will continue, but the RED LED indicates that there is a
problem with the performance mix that really should be
addressed, by either identifying the problem microphone
and reducing its individual channel fader or by reducing the
overall level, bringing down the master faders.
Fixed Anti Feedback Control
Set up the performance system on stage for normal
operation, for example, by placing all microphones in their
typical positions and faders on the mixing desk set to that
of a typical mix. Set the master faders initially in their
minimum settings.
FIXED AFC setup can only be performed if LIVE AFC is
off. If the LIVE AFC indicator on EVOi.net is on, press
and hold the LIVE AFC button until the filter indicators
and the LIVE AFC indicators are extinguished.
Now
very slowly push the master faders up on the mixer
(the
slower the action, the more accurate the detection and
allocation of filters will be). If feedback occurs, each EVO
Loudspeaker will eliminate it. As you continue to push the
faders up more feedback may occur at other frequencies,
and you will see that the FILTERS FREE indicators show
more filters being used.
When all the filters have been used, the FIXED SETUP
indicator will stop flashing. You can quit the FIXED AFC
setup at any time by pressing any button as long as all of
the available filters have not been used. The FIXED AFC
SET indicator will illuminate and Fixed Anti Feedback
Control has been set and is ready to go.
It is advisable to keep extraneous noises to a minimum
during this procedure to prevent inappropriate allocation of
filters.
Clearing Anti Feedback Filters
Both sets of Live and Fixed Anti Feedback filters can be
cleared by pressing and holding their respective buttons. As
you hold the button each allocated filter is removed
sequentially. The FILTERS FREE indicators will show
filters being removed.
If during this process a filter is removed and feedback
occurs, releasing the button will instantaneously re-insert
the filter.
Now press-and-hold the round FIXED AFC SETUP
button until the FIXED SETUP indicator starts flashing.

EVOi.net
APPLICATIONS
EVOi.net is the “network” center of any EVO Loudspeaker System. It facilitates access to all EVO Loudspeaker functions
and monitoring. EVO Loudspeaker Systems have been optimized for small to mid-size venues, where a pair will sufficiently
reinforce sound for an audience of up to five hundred people. They have been designed with specific applications in mind:
schools and sports facilities; places of worship; and performance venues. Typically the program of events are quite varied
and high quality reinforcement is required for speech, live music and recorded music playback. This section refers to typical
applications identified in the EVOi.324 Users Guide and describes how to hook up EVOi.net and optimize the placement
and position of the dedicated Measurement Microphone. These are very simple instructions and are for ideal situations. As
guidelines, they are approximate and it may not be possible to follow strict practice. The beauty of EVO is that all the setup
routines only take a few moments and that if one configuration doesn’t work, then re-setting the entire system is only a few
moments away!

POWER UP OPERATION
There are two scenarios:
a) EVO Speakers have been changed/replaced or the
speakers hook up configuration is different.
b) EVOi.net has been changed/replaced.
Because of the difficulty in reliably determining which is
the appropriate scenario, the same procedure will be used in
both situations, and will allow the user to go back to the
alternative data set:
1. When powered up, the EVOi.net will download the
data from the speaker and compare the EVO loudspeaker data with the EVOi.net stored data. If the data
in the EVO loudspeakers does not match the data in the
EVOi.net, the SPEAKER STATUS indicators will
signify power-up disagreement error. Audio will not be
allowed to pass at this time.
2. The EVOi.net will backup the data that came from the
speakers to preserve it.
3. The EVOi.net will upload the original stored data into
the speakers.
4. If the user is happy with this, any button press will
clear the error, and unmute the system
5. To swap the data with the backed-up original speaker
data, the press MAIN OUT SETUP 1&2, AUX OUT
3&4, and DELAY SETUP simultaneously to download
the backed up EVO system data back into the EVO
loudspeakers. This will back-up the original EVOi.net
data, which the user can swap back to if required.
6. As a last resort the user may press the square LIVE
AFC ON, EQ SELECT, and AEQ ON buttons
simultaneously and restore the EVOi.324 settings to
their original factory defaults.
APPENDIX
EVOi.net
25
TROUBLESHOOTING
EVOi.net is used as the interface for the set up and
operation of EVO Loudspeakers. The following section
may help in resolving some problems that may occur.
1. The front panel is inoperative and does not
respond to button pressing:
Check the LOCKED indicator. If it is illuminated, then
disengage the LOCKOUT Switch on the rear panel (#14
page 6).
2. The CLIP LED’s on the EVOi.net’s INPUT (#1
page 4) are illuminating:
The input signal level to EVOi.net is too high. Lower the
input level to EVOi.net. This is likely to occur if the EVO
Loudspeakers are not powered up and there is no audible
way of hearing a ‘clipped’ signal. If this is the case,
determine the cause of the EVOi.324’s not producing
sound.
3. The SPEAKER STATUS indicators are flashing:
If only the RED LED is flashing occasionally, it indicates
that the electronics in the EVOi.324 connected to that
OUTPUT has detected a signal level that engages the builtin limiting circuitry. Lowering the signal level will resolve
this WARNING.
After the error code is noted, the less serious errors may be
cleared by pressing any of the rectangular buttons on the
front panel of EVOi.net.
4. I’m sending signal, but one channel is not
working?
Check the configuration of MONO SUM (#15, 16 on page
6). MONO SUM engaged will allow signal from INPUT A
to flow to OUTPUTS 1 & 2 and 3 & 4 simultaneously.
With MONO SUM disengaged, signal from INPUT A will
flow to OUTPUTS 1 & 3 and signal from INPUT B will
flow to OUTPUTS 2 & 4.
5. My rear speakers aren’t working.
Has delay setup been engaged? (Is the DELAY SET LED
on above DELAY SETUP button)?
In a delay setup, typically the rear speakers are lowered to a
level (6-10dB) and delayed (approximately 15ms behind
any signal arriving from the main speakers) that allows
them to effectively disappear, forcing the localization of the
image to the front pair. Use the test function (if enabled) to
determine presence of all 4 speakers.
SPEAKER STATUS Error codes
Error codes are flashed as a sequence of two digits. After
the first digit, there is a short gap and after the second digit,
there is a longer (1 second) gap. Errors are prioritized, so if
a speaker has more than one error condition, the most
important error will be shown until it is cleared, at which
point the second error will be shown. Pressing any button
when an error code is being displayed will clear the highest
priority error.
An error/status code is being reported when the green
(OKAY) LEDs begin flashing. Take note of the green
LED’s flashing code and its most likely cause using the
chart on page 27.
26
6. Anti Feedback is on, yet my system is still
feeding back.
Has setup routine been used?
Have all filters been used? While the anti-feedback circuit
has been carefully designed to minimize the impact of
feedback, there will still be a point beyond which the
system is so feedback prone that further increase in gain
will result in additional feedback. A point is eventually
reached where so many feedback frequencies must be
removed, that it either requires an enormous number of
filters, or it requires lowering gain to keep the system
usable. The gain to the microphone should be lowered to
prevent the creation of feedback.

Microphone was not connected, or the cable is defective.
4 3 Measurement Level Error. (Input too quiet during Auto EQ/Delay setup.) The chosen location
is too far away from the loudspeaker for an accurate determination of the system response.
Move the microphone forward and try again. For accurate results, the microphone should
typically see a level of 85dB +/- 2dB. (This limits distance to speaker for Auto EQ to about
17m (or 56 feet) in a non-reverberant room). It should be noted that background noise level
will alter this threshold slightly.
4 4 Auto measure polarity reversal. The cable between the EVOi.net Measurement Microphone is
incorrectly wired (polarity reverse in the cable). Replace or repair cable and try again. Also,
this may occur if the Measurement Microphone is placed behind the loudspeaker cabinet or is
too close to a large wall. Reposition the Microphone. Clear the error and try again.
4 5 Speaker Impulse Response in Error (during AEQ/Delay setup). The microphone is placed in a
poor location that is not accurately receiving the speaker signal. Move the Microphone.
