Introduction
Dear customer,
Congratulations on choosing an ADAM Audio P22A nearfield monitor!
ADAM loudspeakers are built for maximum quality reproduction and audio
perfection. With the P22A you have selected a precise, high resolution speaker system that allows you to professionally evaluate audio recordings. This
monitor meets highest expectations in sound quality and craftmansship.
This manual is intended to provide you with information about your new
ADAM. It contains important information regarding safety, setting up,
handling, and warranty. We request that you read these sections carefully
to ensure an easy set up and to prevent potential problems.
The P22A is a compact nearfield monitor. It is perfectly suited for small control rooms, recording vehicles and post-production suites—an ideal tool for
situations where a combination of no-compromise sound reproduction and a
small footprint is required.
The P22A is a two-way ported active system that uses a single ART tweeter,
ensuring full compatibility with the latest expanded high frequency resolution
media formats, and a conventional bass/midrange driver below the crossover
frequency of 1.8 kHz. Each section uses an individual amp with continuous
output of up to 100 Watts (RMS).
If you have any questions about this or any of our products, please don’t hesitate to contact us–we will be happy to assist you in any possible way.

1. Quick Start
Important information for set up
1.1
Acclimation: After having unpacked your loudspeaker, please allow the system to acclimate to the temperature of the room. Please do not connect the
speaker for approximately an hour.
HQ Cabling: We recommend using high quality cables to guarantee optimal
performance.
Solid stand: It is important to ensure the speakers stand firmly on a solid
ground!
Package: We recommend not to damage the package and to retain it. The
original packaging is the best guarantee for safe transportation (see 7.).
Break-in time: Please note that the loudspeakers will need a few days to
achieve optimum sonic performance.
Quick start P22A
1.2
Before connecting the loudspeakers to your audio components and the
power source make sure that both the loudspeakers and your audio system
is switched off!
Set all level controls fully counterclockwise.
a)
Connect the loudspeakers with your audio units: Use a XLR cable. The male
b)
plug goes into the loudspeaker, the female plug into your audio component.
Check if the specified voltage matches the voltage of the power supply
c)
you use. If this is not the case do not connect the loudspeakers to a power
source! Please contact your local dealer or national distributor.
If the voltages match, connect the loudspeaker via the included power
cables to two AC sockets.
Switch on your audio system. Switch on the main on/off switches on the
d)
back panel and finally the standby-switch on the front panel of the loudspeakers.
e)
Turn on your source of music and adjust the volume carefully.

2. Speaker Placement
2.1
General recommendations/advises
Direct sound ways: There should be no obstacles in the way from the monitor
to your ears. You should be able to see the speakers completely.
Distance to walls: The distance to the surrounding walls should be at least 40
cm to avoid early reflections, which will degrade the sound.
Alignement: The loudspeakers should be aligned with the listener’s position.
Nearby objects: Please note that vibrating parts of nearby objects can mask
the sound.
Mechanical adjustements: If you plan to modify the speaker cabinet (e.g.
drilling holes), please contact us before doing so. Usually, we will handle your
warranty obliging.
2.2
Vertical set up
The P22A has been designed for a vertical set up. The speakers must be
positioned on a firm ground or a stand.

2. Speaker Placement
Horizontal set up
2.3
If you choose to use your speakers in horizontal position as indicated below,
please make sure that the set up is mirror symmetrical, i.e. that the
tweeters both face either the outsides or the insides. This is crucial for a
precise stereo signal.

2.4
The Stereo Triangle
If the loudspeaker is going to be used for stereo applications, the optimum
listening position should be located in the middle of a stereo triangle. This
means that your listening position will be located at the top of an imaginary
equilateral triangle and the two loudspeakers should be placed at the other
two points of this triangle.
Figure 4: Stereo Triangle
• both loudspeaker and the listening
spot should be a equilateral triangle
• approx. the same distances
between loudspeakers and the loudspeakers / the listening spot
• alignment towards listening spot

2. Speaker Placement
2.5
Surround Placement
Speaker positioning for multi-channel stereo purposes is ideally based on
a circle with speakers placed at 0° (Center), 30° (Front Right), 110° (Rear
Right), 250° (Rear Left), 330° (Front Left), with the listener being the circle’s
center (Radius between 0.7-2.0 m). This ITU recommended configuration may
vary depending on the purpose of the control room (music or film). However,
it is recommended to create a symmetrical listening position with the front
side and surround speaker pointing to the listener’s ear.
Figure 5: Surround set up
2.6
Tweeter at the height of ears
The Tweeter should be positioned approximately at the height of your ears. In
case you need to position the speaker in a significant lower or higher position,
the monitor should be angled accordingly.

3. Controls/Speaker Adjustment
3.1
The control panel
On the rear side you will find a control panel that allows detailed fine-tuning
of your loudspeakers to your particular room acoustics and personal listening preferences. The following tips are intended to assist you at using the
controls in the best manner.
Figure 6:
Control panel
Please note that using the controls may have a great impact on the sound
characteristics of your loudspeakers. We recommend using the controls with
utmost care and only after several audio tests with familiar recordings.
3.2
Input gain
‘Input Gain’ regulates the overall input sensitivity of your loudspeaker within
a range of -10 to +10 dB, and controls the volume of your loudspeaker equally
in all frequency ranges.
3.3
High gain
Whereas the ‘Input Gain’ raises or lowers the overall input sensitivity up to
+/-10 dB, the ‘High Gain’ works only within the frequency range of the tweeter (>1.800 Hz) only, raising or lowering up to +/-4 dB.

3. Controls/Speaker Adjustment
High / low shelving
3.4
The other two controls operate in a different manner. The ‘High Shelve’ is
a shelving filter that progressively raises or lowers above 6 kHz up to 6 dB.
Whereas the gains raise or lower a specific frequency range as a whole, the
shelve filters work differently. They do not alter a whole frequency band but
alter in this band, from a certain point (6 kHz respectively 150 Hz in this case)
the frequencies are gradually being changed (see figure 7 & 8).

frequencies above 6 kHz
LED
3.5
There is a diode at the front, above the tweeter. When the loudspeaker is
being switched on, it will flash red a few times. This does not indicate an
overload! It signalizes the control function of the protective circuit. Afterwards, it will start to glow green, indicating power on. If the LED flashes red
during operation, this indicates an overload. The protective circuit will be
activated.

4. Troubleshooting
All ADAM products are designed and manufactured to the highest quality
standards. However, if any problems with your speaker occur, we recommend
to proceed as follows:
Problem: The LED shows normal operation (green) but there is either no or
4.1
only a distorted audio signal.
If both (all) speakers are affected, the reason can probably be found within
the signal path. If only one speaker is affected, the problem will probably be
within this speaker.
a)
Check the wiring
Is the cable defective? Are all cables connected correctly?
Check the signal path
b)
Interchange the cables of both loudspeakers. Does the problem change with
one of the cables?
Connect the monitor as directly to the signal source as possible (please mind
the volume!). Is another part of the signal path (e.g. mixer, subwoofer) defective?
10
If the answer to all these question is ‘no’, the problem is being caused by the
loudspeaker with the utmost probability.
If the answer to at least one of these questions is ‘yes’, there will probably be
another defective device within the signal path.
4.2
Problem: You hear parasitic noises (like humming, buzzing, soughing, crack-
ing).
Please disconnect the signal cables.
If the noises disappear, check the signal path.
If the noises can still be heard, check for other electrical devices close to
the speakers (mobile phones, switching power supplies, etc.). If there is no
interfering device the speaker will probably cause the problem.
