tilation ports.
Assure free airflow behind the speakers to maintain sufficient cooling.
2. Quick Start
Important Information for set up
After having unpacked your loudspeaker, please allow the system to accli-
mate to the temperature of the room. Please do not connect the speaker for
approximately an hour.
We recommend using high quality cables to guarantee optimal performance.
It is important to ensure the speakers stand firmly on a solid ground!
We recommend not to damage the package and to retain it. The original pack-
aging is the best guarantee for safe transportation (see 7.).
Please note that the loudspeakers will need a few days to achieve optimum
sonic performance.

2. Quick Start
Quick Start
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.
Connect the loudspeakers with your audio units: Use a XLR cable. The male
plug goes into the loudspeaker, the female plug into your audio component.
Check if the specified voltage matches the voltage of the power supply
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. Then, switch on the main on/off switches on
the rear panel of the loudspeakers.
Turn on your source of music and adjust the volume carefully.
LED
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. After-
wards, 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.

3. Speaker Placement
Vertical set up
The P11A has been designed for a vertical set up. The speakers must be
positioned on a firm ground or a stand.
Hoizontal set up
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.

3. Speaker Placement
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.
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 4: Stereo Triangle
• both loudspeaker and the listening
spot should be a equilateral triangle

3. Speaker Placement
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.
Figure 6: Tweeter at height of ears / speaker angling
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.

4.Controls/Speaker Adjustment
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 listen-
ing preferences. The following tips are intended to assist you at using the
controls in the best manner.
Please note that using the controls may have a great impact on the overall
sound characteristics of your loudspeakers. We recommend using the con-
trols with utmost care and only after several audio tests with familiar record-
ings.
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.

English
4.Controls/Speaker Adjustment
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 tweet-
er (>1.800 Hz) only, raising or lowering up to +/-4 dB.
High / Low Shelving
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 8 & 9).

ROOM EQ >6 kHz for the high
frequencies above 6 kHz

ROOM EQ <150 Hz for the low
frequencies below 150 Hz

5.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
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.
Check the wiring
Is the cable defective? Are all cables connected correctly?
Check the signal path
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) defec-
tive?
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.
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.

6.Maintenance
Please switch the loudspeaker off before cleaning!
Please note that the diaphragms build up a magnetic field. Do not play with
magnetic items at close range to the diaphragms.
Please make sure that no liquids get inside the cabinet. Do not spray any
fluids on the speaker. Do not use a wet cloth for cleaning.
Do not use flammable or acidly chemicals for cleaning.
Do not touch the membranes of the loudspeakers.
We recommend using a lint-free, damp cloth for cleaning.
The loudspeaker membranes may be dusted using a very soft brush.
7. Transport / Package
In case you have to send your speakers to any other location, it is of vital
importance that you use the original packaging materials. Experience has
shown that it is very difficult to avoid damage if you have to send them with-
out these. ADAM Audio can not be held responsible for damages due to im-
proper packaging.
If a transport is necessary and the original package is no more available, a
new one can be purchased from ADAM Audio.
8. Environmental Information
All ADAM products comply with international directives on the Restriction of
Hazardous Substances (RoHS) in electrical / electronical equipment and the
disposal of Waste Electrical / Electronic Equipment (WEEE).

1. Sicherheitshinweise
Bitte versuchen Sie auf keinen Fall, dieses Produkt selbst zu reparieren und
wenden Sie sich bei einem Problemfall an Ihren ADAM Vertragshändler oder
direkt an uns. Wir helfen gerne!
Bitte beachten Sie die folgenden Sicherheitshinweise, bevor Sie Ihre
neuen Lautsprecher in Betrieb nehmen.
Öffnen Sie die Monitore nicht. Gefahr eines Stromschlages! Es befinden sich
keine wartungsbedürftigen Teile im Gehäuseinnern.
Die Lautsprecher müssen mit einer dreipoligen, geerdeten Stromversorgung
betrieben werden. Alle drei Pole müssen stets verwendet werden. Dies gilt
auch für davor geschaltete Verlängerungen oder Verteiler.
Verwenden Sie ausschließlich die spezifizierten Sicherungstypen. Überbrück-
en Sie niemals, auch nicht im Notfall, die Sicherung.
Schalten Sie stets alle Geräte aus, bevor Sie eine Kabelverbindung entfernen
oder neu hinzufügen.
Bitte beachten Sie, dass im Gehäuseinneren sich Magnete befinden, die ein
Magnetfeld aufbauen. Vermeiden Sie, mit magnetischen bzw. paramagnet-
ischen Gegenständen in unmittelbare Nähe der Lautsprecher zu hantieren.
Vermeiden Sie, dass Flüssigkeiten jeglicher Art ins Gehäuseinnere gelangen.
Sprühen Sie weder Flüssigkeiten direkt auf das Gerät, noch nutzen Sie nasse
Reinigungslappen.
Bitte verwenden Sie keine brennbaren und ätzenden Chemikalien zur Reini-
gung dieses Produkts (siehe 6.).
Vermeiden Sie jede Berührung mit den Membranen der Lautsprecher und
blockieren Sie nicht die Bassreflexöffnung.
Gewährleisten Sie eine rückwärtige Luftabfuhr für eine notwendige Kühlung
der Elektronik.

1. Sicherheitshinweise
Zum Trennen des Gerätes vom Stromnetz schalten Sie den Netzschalter aus.
Anschließend ziehen Sie den Netzstecker aus der Steckdose. Der Netzschal-
ter und -stecker müssen leicht erreichbar sein.
Verwenden Sie stets geprüfte Kabel. Defekte Kabel sind häufig die Ursache
für Störgeräusche verschiedener Art.
Setzen Sie dieses Produkt nicht bei extremen Temperaturen ein (siehe 11.),
ebenso wenig in feuer- oder explosionsgefährdeten Umgebungen.
Zu hohe Lautstärken können ihr Gehör schädigen! Vermeiden Sie direkte
Nähe zu Lautsprechern, die mit hohen Pegeln betrieben werden.
2. Quick Start zur Inbetriebnahme
Allgemeine Hinweise zur Inbetriebnahme
Nach dem Auspacken und der Aufstellung des Lautsprechers sollte dieser ca.
eine Stunde unangeschlossen ‚ruhen’, um sich der jeweiligen Raumtempera-
tur anpassen zu können.
Wir empfehlen, ausschließlich hochwertige Kabel zu benutzen.
Bitte beachten Sie, dass mit der Qualität der Monitore die Ansprüche an die
Einspielzeit steigen. Ein ADAM Monitor benötigt daher, abhängig von Pegel
und Nutzungsfrequenz, einige Tage, um seine optimale Klangqualität zu er-
reichen.
Wir empfehlen, beim Auspacken der Teile Ihres neuen Lautsprechers darauf
zu achten, die Verpackung nicht zu beschädigen und aufzubewahren, um den
Lautsprecher bei Bedarf sicher transportieren zu können (siehe 7.).
Die Lautsprecher müssen stets fest und ohne zu wackeln auf einer festen
Unterlage stehen!
