Introduction
First of all, we would like to thank you for choosing ADAM Audio. ADAM Studio Monitors
are built to a maximum in reproduction quality and perfection. You have selected a
precise high resolution active speaker system that allows you to professionally judge
audio recordings. We are condent that these monitors can meet your expectations to
a faithful sound reproduction.
To enjoy the capabilities of your new speakers, please read the following safety and
warranty considerations before connecting these. Get informed about the speaker
placement and the available control elements. The positioning and the acoustical
properties of the control room often play a bigger role than you might think.
The S2A is a professional and compact near eld monitor. A suitable tool for home
studios, small control rooms, recording vehicles and post productions suites.
The S2A is a two-way ported active system that uses a single A.R.T. tweeter and a
HexaCone® bass/midrange driver below the crossover frequency at 1.8 kHz. Each
section uses an individual amp with continuous output of up to 150 Watts (RMS).
The use of our exceptional A.R.T. tweeter ensures full compatibility to the latest
media formats such as DVD Audio and SACD with their expanded high frequency
resolution. At the same time the S2A allows to monitor the low frequency range down to
35 Hz with a at response. Because of the extraordinary stiffness and lightness of
the HexaCone’s® Nomex/Kevlar sandwich membrane, this results in an exceptional
accurate frequency response of the speaker.
If you have chosen the correspondent option, the speakers are magnetically shielded
and can therefore be used in close combination with sensitive equipment like computer
screens.
We very much hope that you enjoy your new monitors and their unique transducer
design. If you have any questions about this or any of our products, don’t hesitate to
contact us - we will be happy to advise you. The Team from ADAM Audio

Safety Instructions
In case of a problem, please either contact your ADAM dealer or us. We are happy to try
and help. Always refer servicing to qualied personnel and never attempt to repair this
product by yourself. Please read through the following safety instructions completely
before setting your system up.
• Do not open the monitor. There are no user-serviceable parts inside.
• Do not expose this product to rain or moisture, never wet the inside with
any liquid and never pour or spill liquids directly onto this unit.
• Never use ammable or combustible chemicals for cleaning audio
components
• Avoid touching the speaker membranes and do not block the woofer’s
ventilation port.
• Assure free airow behind the speakers to maintain sufcient cooling.
• Always use fully checked cables. Defective cables can harm your speakers.
They are a common source for any kind of noise, hum, crackling etc.
• Always switch off your entire system before connecting or disconnecting
any cables, or when cleaning any components.
• This product, as well as all attached extension cords, must be terminated
with an earth ground three-conductor AC mains power cord. To prevent
shock hazard, all three components must always be used.
• Never replace any fuse with a value or type other than those specied.
Never bypass any fuse.
• Never expose this product to extremely high or low temperatures
• Never operate this product in an explosive atmosphere.
• Always keep electrical equipment out of the reach of children.
• Always unplug sensitive electronic equipment during lightning storms.
• If you have not ordered the magnetically shielded version of these monitors,
do not place the speakers to electronically equipment like computer screens.

Quick Start
• After having unpacked your monitor, please allow the system to acclimate to the
temperature of the room. Please do not connect the speaker for approximately an
hour.
• Make sure the power switch at the back of the unit is turned off as well as the switch
on the front of the monitor.
• Connect the XLR-Input (1) of the speaker to the output of your audio system.
Decrease the volume of your audio system to protect your speaker and ears from
damage when switching the system on.
• Now, check the voltage setting (2). It has to conform with the voltage standard of the
country you stay. Please, contact ADAM Audio, should this not be the case.
• Connect the provided power cord to the speaker.
• Switch on the rear power switch rst, then the front switch. By increasing the volume
of your audio system, you should now hear sound.
• To achieve the best possible sound reproduction, please see the following consid erations for speaker placement.

Setting up your speakers

S2A
The S2A is designed for vertical operation. The speakers should be positioned on rm
ground or a stand. Vibrating parts of nearby objects can mask the sound.
In case, you plan to modify the speaker cabinet (e.g. drilling holes), please contact us
before doing so. We will guide you and handle your warranty obliging.
Set up your speakers with the A.R.T. tweeters pointing upwards.
Horizontal placement is possible. Please position both tweeter sections either to the
outside or to the inside. You will get the best linear frequency response from different
listening positions.
Obstacles between the speaker and your ear must be avoided. You should be able to
see the speaker completely. Avoid placement near reective surfaces, too. You will lose
room information!

Setting up your speakers
The Tweeter should be positioned approximately at the height of your ears. In case you
need to position the speaker in a signi cant lower or higher position, the monitor needs
to be angled.
Placement of 2 speakers
The ideal placement of two speakers and a listener in a two-channel stereo listening
situation are the corner points of a equilateral triangle (60° angles). Since the S2A is a
near eld monitor, the best performance will be achieved with a stereo base/listening
distance between 1 and 3 meters.
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 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.
The distance to the surrounding walls should be at least 40 cm to avoid early re ections,
which will degrade the sound.

Controls
The power switch and the XLR-input are located on the rear panel.
The monitor offers adjustment of important parameters on its front panel (see g.)
Standby switches the monitor on and off. Please note that this switch does not separate
the monitor from the mains. The operating state is indicated by a LED that will be lit
green with the system ready to play, yellow if the monitor is turned off. With the rear
power switch turned off, no LED will light.
The monitor comprises a overload protection circuit. In case the input signal is too
high and therefore causes distortion, the circuit mutes the monitor to protect the
speakers. The red Overload-LED will blink as long as the protective action is active. The
maximum input level is reached when the Overload-LED starts blinking. Excessive use
of the monitor in this state will likely result in a reduced lifetime of the components. If
possible, turn down the source signal level.

Controls
INPUT GAIN
To match the monitor’s input to the source signal level, the input sensitivity can be
varied by -10 dB to +10 dB.
ROOM EQ
A detailed way to optimize the reproduction for the room are the two shelve lters
at both ends of the frequency band. Above or below the given cut off frequency the
amplitude is progressively changed. The given dB values occur at 30 Hz and 15 kHz. We
show ve curves, the controls can be changed continuously however.
ROOM EQ <150 Hz Shelve Filter
with 150 Hz cut off frequency
ROOM EQ >6 kHz Shelve Filter
with 6 kHz cut off frequency
HIGH GAIN
The voltage gain of the tweeter amplier and thus the complete tweeter level can be
varied in a ±4 dB range. This is a considerable change in the sound characteristic and
should be used with caution. In case you have a considerably damped room or if there
is a special taste you are after this control will serve you well.
