The measurement process is designed to be resilient against background noise, but it can be
bene icial to choose a moment when the listening room is relatively quiet. It is also a good idea
to turn o any noisy equipment such as air conditioning or the duration o the measurements.
%
Set up the supplied microphone stand. Attach the microphone to the stand and connect
the microphone cable to the microphone. Adjust the stand so that the microphone is at
the center o the primary listening location, at about ear height.
I your system eatures subwoo er(s) that have adjustable low-pass ilters, it is good to
disable them, or set the cut-o requency to their maximum value.
Make sure your active speakers or power ampli iers and/or subwoo ers are connected to
the correct outputs and turned on.
It is good to adjust the gain o all connected speakers so that the main speakers and
subwoo ers are approximately equally loud.
Turn on the Anti-Mode X4 unit, wait a ew seconds until the boot sequence inishes.
I you have not yet chosen a language, you are prompted to choose one now.
Plug the microphone cord into the connector located at the ront panel. The calibration
menu opens automatically.
Notice: you can cancel the calibration at any time by unplugging the microphone cable.
Select typical calibration rom the menu by rotating the control wheel and click the
wheel button when the item labeled “Typical” is highlighted.
Rotate the wheel to select a speaker con iguration that best matches the connected
audio equipment. You can ind more in ormation about the calibration modes urther in
this manual. Click the wheel button to proceed.
Adjust calibration volume by rotating the wheel or using the remote controller until the
signal is clearly audible. Click the wheel button to start the calibration process.
When the calibration process has inished, unplug the microphone.
Congratulations, your system has been optimized! Now it is a good time to put on some o your
avorite music and enjoy the improved sound.
Notice: The automatic calibration process targets a balanced overall sound, with slightly
elevated response towards the low bass region. The response can be adjusted in multiple ways
to suit your personal taste. You can read more about sound pro iles and shaping the sound next.

Sound pro iles allow to store several sets o room measurement, correction, and user
parameters. During the irst calibration, the system automatically creates up to six di erent
sound pro iles. These pro iles have individual sonic characteristics. You can switch between the
pro iles by pressing the A, B, and C buttons on the remote1. A single press will activate one o
the pro iles “A”, ”B”, or “C”. A double press will activate one o the pro iles “D”, ”E”, and “X”.
You can also activate a pro ile by navigating to the “Sound Pro ile” section in the Main Menu.
-,
I you ind a preset that you like, you can replace any other pro ile with it by navigating to
”Pro ile” section in the main menu. Any user-made sound adjustments will only apply to the
currently active pro ile and are saved to that pro ile. I you wish to use di erent settings or
di erent scenarios ( or example, “classical music”, “home theater mode”), you can create a
pro ile or each o these.
Tip: Di erent pro iles are represented by di erent colors throughout the inter ace. It is possible
to customize these colors by navigating to “Screen” section o the Main Menu.
(&
You can optimize or a di erent listening location by irst activating a sound pro ile and then
per orming the calibration procedure. The new calibration will override parameters that are
related to Anti-ModeTM correction, but keeps other settings intact.
Notice: Only the initial calibration a ects all six pro iles. I you want to populate all six pro iles
again, select ”Factory Reset” rom the main menu. However, be aware that a actory reset will
clear all data stored in the memory!

Treble tilt controls can be ound in the “Sound” section o the main menu. Treble tilt is a
power ul shelve-type ilter that can be applied to shape the target response at high requencies.
It has two parameters: gain and bandwidth. The parameters can be adjusted with the control
wheel (hold down and rotate the wheel to adjust bandwidth) or using the remote controller.
Pro ile buttons A and C will adjust the bandwidth. The e ect o the ilter can be heard in real-

Anti-Mode X4 supports up to nine ully parametric EQ ilters (PEQ) that can be placed at
arbitrary center requencies, using variable bandwidth and gain. An EQ can be set to a ect both
channels (the de ault) or either le t or right channel separately.
Notice: while PEQs can be used to shape the system response at a very ine level, correcting
small bumps manually a ter the calibration is typically not advisable. Striving or maximally lat
curve in amplitude response might induce audible problems in the time domain, something that
might not be apparent in the measured response. We suggest applying parametric equalizers
with moderation. Not all dips in the response can or should be corrected!

mode. Follow the screen to guide you through the calibration or measurement process. Press OK

SPEAKER CONFIGURATION
First de ine your speaker setup. A normal stereo system with two speakers and no subwoo ers is
re erred to as a ”2.0” system. The speakers should be connected to the Primary outputs (XLR,
RCA, or a digital output).
A ”2.1” system has also a single subwoo er. The speakers should be connected as above, and the
subwoo er to either le t o right Auxiliary output (XLR or RCA).
A ”2.2” system has two speakers and two subwoo ers. The connections are as above, but
subwoo ers are connected to both le t and right Auxiliary outputs (instead o one).
I you have only subwoo ers to connect, you can choose the ”0.2” con iguration. In this case,
connect the subwoo ers to the Primary outputs.
Anti-Mode X4 incorporates a patent-pending automatic cross-over optimization system. When
normal calibration is chosen with ”2.1” or ”2.2” system, this optimization system measures the
audio reproduction parameters o the subwoo ers and speakers and uses that in ormation to
orm a digital cross-over network that maximizes the integration o the speakers and subwoo ers
while minimizing the overall distortion o the system.
VOLUME LEVEL DETECTION
Be ore Anti-ModeTM calibration per orms its measurements, the measurement level must be
adjusted by the user. Thanks to a very robust measurement method, the system response can be
obtained at even very low signal levels. However, too low signal levels may result in errors in the
results when air-conditioning and other stationary sounds have more opportunities to a ect the
measurement.
To make inding a suitable level easier, two indication lines are presented on the screen:
Minimum (Min) and Good. The microphone pickup level is indicated by a white horizontal bar
emerging rom the le t o the screen. Make sure your speakers and subwoo ers (i any) are
active, then gradually increase the volume using the Volume + and Volume – buttons on the
remote or rom the control wheel so that the generated test noise is properly audible. Increase
the output volume until the level indicator is between the Min and Good bars. However, it is not
always necessary to exceed the Min bar.
#&6 )6;:6.: !)>)?
OWNER'S MANUAL
I the sound is audible, but the indicator is not moving at all, please check the microphone
connections and do not proceed until this issue has been solved and the indicator bar is moving
according to sound level.
Using a higher level or measurement can produce a more accurate room response, but too high
level could cause clipping o the signal in some part o the system. There ore it is not
recommended to exceed the Good level.
Note that the level o the calibration can a ect the automatic cross-over designer as it will also
measure the distortion characteristics o the speakers and subwoo ers. It is recommended to use
a volume level that resembles the normal listening volume level.
A ter adjusting the level, press OK or click the wheel button to start calibration.
The calibration per orms multiple measurements depending on the system con iguration. This
will take several minutes. You can leave the room, but do not open or close doors or windows
during measurements.
A ter all measurements are inished, you are prompted to unplug the measurement microphone.
Remove the microphone and you are able to view the calibration results.
FOR BEST RESULTS: When calibrating a system with subwoo ers, set the built-in
lowpass ilters o the subwoo ers to bypass or to the highest available cuto
requency.
PLEASE NOTE: A ter Anti-Mode gets rid o room resonances, it may appear that
the result sounds good but is lacking in bass. One possible reason is that the
listener has grown used to the exaggerated bass response caused by room
resonances.
I you eel that you need to increase the overall bass level, you can do this using
the Compensation Gain setting or using Bass tilt.
+"
In the advanced calibration mode you have control over all o the parameters.
When choosing a 2.2 system (whether speakers and subs or 0.2.2) you can set the cross-over
requency between 20Hz and 1540Hz. You can also adjust the other parameters: Q value, ilter
order, and also the amount o cross-over overlap.

COMPENSATION GAIN
”Compensation Gain” compensates or the overall di erence in bass energy when peaks in
response are removed. This is a matter o personal pre erence, so this setting is the irst to
adjust i a ter calibration you perceive too much or too little bass. The requency limit or the
compensation ilter is dependent on the correction limit, but it doesn't exceed 500Hz.
CORRECTION RANGE
”Correction Range” sets the requency limit or the automatic Anti-ModeTM correction.
Frequencies above the limit are not altered. At any time a ter calibration, the correction range
can be changed to your pre erence. A new correction is created rom the stored measurement
data o the current pro ile without needing to measure again.
VIEWING ROOM RESPONSE AND CORRECTIONS
”Be ore / A ter” and ”User Measurements” show the measured room responses, i they have
been measured or this pro ile. You can scroll the cursor with remote or using the control wheel,
and zoom the response by rotating while keeping the wheel button pressed.
SMOOTH GRAPH
”Smooth Graph” con igures whether smoothing is applied when displaying responses. Having
smoothing on is usually appropriate when considering how the response sounds to the human
hearing, especially at the higher requencies.

BASS TILT, TREBLE TILT
Bass tilt provides the user with a shelve-type ilter to increase or decrease bass. Use the control
wheel to adjust the gain, with the wheel button pressed you can adjust the requency. You can
also adjust the gain with + and – o the remote, and the requency with the A and C pro ile
buttons.
Treble tilt works in the same way as the Bass tilt, but or the treble requencies.
INFRASONIC
The very lowest requencies can be eliminated rom the output by using the in rasonic ilter.
When enabled, the cuto requency can be adjusted rom 2Hz to 200Hz using its own menu
item.
USER EQ
With the User EQ tool you can create your own ully parametrizable ilters. But be care ul, a
straight amplitude response may not behave so nicely in the time domain!
HEADROOM
Headroom de ines how much reserve to keep in calculation to be able to boost requencies
without the signal becoming saturated.
Reducing headroom may allow higher maximum output volume. However, digital clipping may
occur i too many boosting ilters are used without su icient headroom.
CH BALANCE
I you have an asymmetric listening position or speaker locations, channel balance adjustment
may be needed or the channels to appear equal loudness.
SUB LEVEL
I the calibration included subs, their volume relative to the speakers can be adjusted manually.
