1. Quick Start
Important information for set up
Acclimation: After having unpacked your loudspeaker, please allow the sys-
tem 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 rmly on a solid
ground (if they are not wall-mounted)!
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 S7A Mk2
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 specied 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. Switch on the main on/off switches on the
front panel of the loudspeakers.
Turn on your source of music and adjust the volume carefully.

2. Speaker Placement
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.
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.
Tweeter at the height of ears: The tweeters should be positioned approxima-
tely at the height of your ears. In case you need to position the speaker in a si-
gnicant lower or higher position, the monitor should be angled accordingly.
Stereo set up
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 listen-
ing 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 set up
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 conguration may
vary depending on the purpose of the control room (music or lm). However,
it is recommended to create a symmetrical listening position with the front
side and surround speaker pointing to the listener’s ear.

3. Controls/Speaker Adjustment
The front (control) panel
On the front you will nd a control panel that allows detailed ne-tuning of
your monitors to your particular room acoustics and personal listening pref-
erences. 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.
X-Curve Filter
In large lm score mixing rooms, it may be desirable to have a representation
of the sound in the theatres. To meet the ISO 2969 Standard, the Dolby™ X-
curve has to be applied. The X-curve engages a 3 dB per octave roll-off above
2 kHz. The S7A Mk2 and S7A Mk2 have a switch located below the input
selector that activates this lter, eliminating the need for external processing
during the lm mix.

3. Controls/Speaker Adjustment
Driver gains
Whereas the ‘Input Gain’ raises or lowers the overall input sensitivity up to
+/-10 dB, the ‘Driver Gains’ work only within the corresponding frequency
range, raising or lowering from +/-2 to +/-6 dB.
High / low shelving
The other two controls operate in a different manner. The ‘High Shelve’ is
a shelving lter that progressively raises or lowers above 6 kHz up to 6 dB.
Whereas the gains raise or lower a specic frequency range as a whole, the
shelve lters 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 gure 4 & 5).
Bass EQ Section (parametric EQ)
There are three fully parametric EQs (20 Hz to 200 Hz) that
can be used to combat standing waves in the control room.
The EQs can be bypassed individually or as a group so that
their overall effect can be analyzed in direct comparison to
the unaffected signal.
LED Dim
All LED indicators can be dimmed if necessary by pressing the ‘LED Dim’-
button.

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

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

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
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.

5. Maintenance
Please switch the loudspeaker off before cleaning!
Please note that the diaphragms build up a magnetic eld. 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
uids on the speaker. Do not use a wet cloth for cleaning.
Do not use ammable 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.
6. 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 difcult 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.
7. 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).
For disposal, please consult your local authorities for further information.

1. Quick Start zur Inbetriebnahme
Allgemeine Hinweise zur Inbetriebnahme
Akklimatisierung: Nach dem Auspacken und der Aufstellung des Lautspre-
chers sollte dieser ca. eine Stunde unangeschlossen ‚ruhen’, um sich der
jeweiligen Raumtemperatur anpassen zu können.
Einspielzeit: 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 erreichen.
Verpackung: Wir empfehlen, beim Auspacken darauf zu achten, die Verpack-
ung nicht zu beschädigen und aufzubewahren, um den Lautsprecher bei Be-
darf sicher transportieren zu können (siehe 6.).
Sicherer Stand: Die Lautsprecher müssen stets fest und ohne zu wackeln auf
einer festen Unterlage stehen!
Inbetriebnahme
Vergewissern Sie sich vor Anschluss der Kabel, dass sowohl die Lautsprecher
(Netzschalter) als auch die betreffenden Komponenten Ihrer Audio-Anlage
ausgeschaltet sind und stellen Sie die Lautstärke auf Minimum.
Verkabelung mit Signalquelle: Verbinden Sie die XLR-Eingänge über ‚männli-
che’ XLR-Stecker mit dem Ausgang Ihrer Audio-Anlage.
Überprüfen Sie, ob die gekennzeichnete Nennspannung mit der Nennspan-
nung in Ihrer Umgebung übereinstimmt. Sollte dies nicht der Fall sein, schlie-
ßen Sie die Lautsprecher in keinem Falle an eine Stromquelle an und kontak-
tieren Sie Ihren Fachhändler. Bei Übereinstimmung schließen Sie mittels der
Netzkabel die Lautsprecher an zwei Steckdosen an.
Vergewissern Sie sich, dass der Ausgangspegel (Lautstärke) Ihrer Audio-
Anlage niedrig eingestellt ist bzw. auf Minimum steht. Schalten Sie zuerst
Ihre Audio-Anlage, dann den auf der Rückseite der Lautsprecher bendlichen
Netzschalter ein.
Beginnen Sie die Wiedergabe und regeln Sie schließlich die Lautstärke vor-
sichtig auf den gewünschten Wert.

2. Empfehlungen zur Aufstellung
Allgemeine Empfehlungen
Direkte Schallwege: Vermeiden Sie Hindernisse im Wege des Schalls zu Ihren
Ohren. Sie sollten die Lautsprecher komplett sehen können! Vermeiden Sie
ferner eine Aufstellung neben stark schallreektierenden Objekten.
Wandabstände: Die Abstände zu Wänden sollten nicht geringer als 40 cm
betragen, um ‘early reections’ zu vermeiden.
Ausrichtung: Die Lautsprecher sollten auf den Hörplatz hin ausgerichtet
sein.
Objekte in der Nähe: Mitschwingende Teile können den Klang maskieren,
selbst wenn es nicht offensichtlich „scheppert“.
Mechanische Eingriffe (Wandmontage etc.): Sollte ein mechanischer Eingriff
zur Aufstellung/Aufhängung notwendig sein (Schrauben oder ähnliches), so
setzen Sie sich bitte vorher mit uns in Verbindung. In der Regel gibt es hier
keine Probleme, die Garantiebestimmungen werden kulant gehandhabt.
Horizontale Aufstellung (spiegelsymmetrisch)
Die S7A Mk2’s werden als A und B Lautsprecher gebaut, um bestmögliche
Symmetrie im horizontalen Betrieb zu gewährleisten – entsprechende
Markierungen nden Sie auf der Verstärkerplatte an der Rückseite. Dabei
bedeutet A dass, das linke Basschassis (von vorne gesehen) als reiner Tieftöner
(nur bis 150 Hz) arbeitet, während das rechte Chassis als Tief-Mitteltöner bis
1800 Hz überträgt. Bei der B-Version hingegen ist es umgekehrt.
Für eine genaue Stereoabbildung ist es nötig, dass die S7A Mk2
spiegelsymmetrisch angeordnet werden! Das bedeutet, die Lautsprecher
sollten in einer der beiden folgenden Weisen aufgestellt werden, entweder
so:

2. Empfehlungen zur Aufstellung
Oder so:

Die Lautsprecher sollten nicht so aufgestellt werden:
Abbildung 2: falsche Anordnung
Zweikanal Stereo
Die gemeinhin günstigste Lautsprecheraufstellung im Zweikanal-Stereobe-
trieb ist das so genannte ‚Stereodreieck’. Die Lautsprecher und der Hörer
stehen bzw. sitzen in den Eckpunkten eines gleichseitigen Dreiecks (60°-
Winkel). Im Allgemeinen gilt, dass der Abstand der Lautsprecher zueinander
dem Hörabstand entsprechen sollte.
