1.1 Important Information
Before you start to install the DA-SX, please make sure that the loudspeakers are
being switched off and also to unplug the power plug.
Please act with caution while installing the converter. It has been design to
perfectly fit into the slot. If you feel too much resistance when trying to insert
the DA-SX, do not use too much force. In case of problems please contact our
support team.
1.2 Installation
a) Unscrew the two screws of the blind plate on the rear side of your speaker. Take
off the blind plate.
b) Insert the DA-SX in the slot. If you feel a resistance, this could be caused by the
two capacitors in the slot. In this case, push them gently to the side.
c) Use your thumb to push in the converter all the way into the slot.
d) Use the two screws to screw in the panel tight.

DA-SX Manual / english
One of the most frequently asked questions are: Can I use the digital and the analog
inputs simultaneously? Yes you can. Both signals are being mixed together internally.
For highest quality and optimized signals, we recommend to use only one connection
at a time and to unplug the cable not being used.
2.1 AES3 (XLR)
Probably the most favored connection for long cable ways
up to 100 meters.
Please only use authentic “AES/EBU” digital audio cables,
which are balanced and have an 110Ω wave impedance.
Please do not use a ‘normal’ XLR microphone cable.
Please do neither extend nor shorten the cable.
2.2 SPDIF coaxial
For unbalanced 75Ω coaxial cables with RCA plugs.
Again, please use specified digital cables (up to about 10m) only,
no other RCA cables. Do not extend the cable.
Please note:
The RCA plug connection is mechanically less stable than other connections.
2.3 AES3 optical (TOSLINK)
For TOSLINK optical fiber cables. Maximum length depends
on the quality and/or used fiber technology, usually up to 10m.
Please note:
In principle, the TOSLINK connection is mechanically a rather fragile one.

2.4 Digital Thru (XLR)
The input signal is being reproduced 1:1. This connection is
for connecting the second speaker through the first one (for
stereo reproduction).
Please only use authentic AES/EBU digital audio cables,
which are balanced and have an 110Ω wave impedance.
Please do not use a ‘normal’ XLR micro cable. Please do
neither extend nor shorten the cable.
Never plug a cable carrying a digital signal into an analog
connector or vice versa!
2.5 Word Clock In
This connection is for a Word Clock used in many studios.
The Word Clock needs to have the same frequency as the
sampling rate of the digital signal. Also, the two frequencies
need to be absolutely synchronous.
By default, the input is terminated with 75Ω. If you wish to time-phase externally
and/or to loop through the Word Clock circuit to another device, the time-phasing
can be deactivated by a jumper on the bottom side of the converter (please see
3.4).
However, we recommend to use a direct single connection between a Word Clock
splitter and a device since the external time-phasing and looping through requires
BNC-Tee pieces and BNC terminators. That makes it more susceptible to errors.
Cables: 75Ω coaxial cables with BNC plug-in connectors (as “Word Clock cable”
on the market).

3.4 External Synchronisation to a Word Clock
If you operate several SX monitors and wish to make sure all speakers
get their sampling values simultaneously by being on the other hand
independent of digital cable lengths, using a Word Clock can be
advisable. In this case, the D/A converters do not need to reconstruct
the sampling rate from the stream of data (something that cannot be
done without small imprecisions concerning the timing). Instead, they
get a clean clock pulse ready to be used.
That is why the Word Clock needs to be in exact synchronicity with the
physical sampling rate of the incoming data stream. A real divergence is
not permitted. If the divergence becomes too big (more than one or two
samples) the D/A converter has to either double the samples or drop
them. This can result in increasing distortion or even in considerable
parasitic noises (Jitter). If you have to use asynchronic rates anyway,
you will need an external asynchronic resampling converter.
• If you do not have a Word Clock connected or do not wish to use a
Word Clock that is being connected, switch off the Word Clock (LED
is off).
• If you want to synchronise the D/A converter with a Word Clock please
activate the Word Clock input (LED is on).
Please note:
If the Word Clock input is activated but there either is no cable connected
to the input or the cable does not carry a signal, the converter works
exactly the same way as if the input were not activated. The converter
automatically switches to standard operating mode.

4.1 Attenuation settings
To alter the volume of the audio signal and to adapt it to
specific requirements, you can use the “Att.” button.
The attenuation works within 5 cyclic steps (after the last
step follows the first) and each step attenuates the signal
by 10 dB.
Setting LED
-40 dB (factory setting)
-30 dB
-20 dB
-10 dB
0 dB
4.2 Notes on Level settings
The settings from -40 dB to -20 dB are rather suitable for monitoring
finished mixes, already mastered musical pieces or final consumer
sound carriers, especially if they have been mastered at high volumes.
The settings from -20 dB to 0 dB will be preferred when it comes
to monitoring of unmastered (sub)mixes, raw single audio tracks or
signals, etc., where the dynamic range of a 24Bit sampling is not being
fully utilized.
The two volume controls on the frontpanel of your SX monitor are not
active (whereas the filters are active ) when you use the digital inputs.
Thus, a fine tuning of the volume other than the 10 dB steps has to be
done in the digital domain.
Please note:
Especially at attenuation steps of -20 dB to 0 dB it is possible that you
overdrive your SX monitor. We recommend utmost care when using the
digital settings.

All ADAM products are designed and manufactured to the highest quality standards.
However, if any problems with your D/A converter card occur, we recommend to
proceed as follows:
5.1 Problem: The blue “D/A” LED on the frontpanel is glowing but there is no audio
signal:
• The “D/A” LED only glows when a valid digital audio data stream is being re-
ceived correctly. If there’s no audible signal, there probably is ‘digital silence’ (i.e.
the channel is muted via the mixing desk, etc.).
5.2 Problem: I have plugged in a cable that surely carries a valid audio data stream
but neither is the “D/A” LED glowing nor is there any audio signal:
• Have you chosen the correct input with your D/A converter?
• Are you using a specified digital cable, not longer than necessary and in one
piece?
• Have you accidentally plugged an AES/EBU digital cable into the analog input?
5.3 Problem: I can hear parasitic noises.
• If you are using word clock: a) Does its rate fit the digital signal and b) is it really
sample-synchronous to the digital signal?
• Some word clock splitters allow for multiples of the incoming frequency. Please
make sure that you have not accidentally set for a multiple.

DA-SX Bedienungsanleitung / deutsch
Eine besonders häufig gestellte Frage betrifft die Möglichkeit, ob man den analogen
und den digitalen Eingang gleichzeitig nutzen kann. Ja, denn die Signale von analogem
und digitalem Eingang werden intern zusammengemischt. Wir empfehlen jedoch, für
höchste Qualität und einen optimimalen Rauschspannungsabstand, immer nur eine
Eingangsart zu benutzen und das nicht benötigte Kabel abzuziehen.
3.1 AES3 (XLR)
Die bevorzugte Anschlussart auch für lange Kabelwege
bis 100m.
Bitte verwenden Sie nur echte AES/EBU-Digitalaudio-Kabel,
symmetrisch und mit 110Ohm Wellenwiderstand (kein normales
XLR-Mikrofonkabel) und vermeiden Sie es, Kabel zu verlängern
oder zu stückeln.
3.2 SPDIF coaxial
Für unsymmetrisches 75Ohm-Coaxialkabel mit RCA-Steckern
(Cinch-Stecker).
Bitte verwenden Sie auch hier nur spezifizierte Digitalkabel
(bis max. 10m) und vermeiden Sie es, diese zu verlängern.
Bitte beachten Sie:
Die RCA-Steckverbindung ist mechanisch weniger stabil als andere Anschlüsse.
3.3 AES3 optisch (TOSLINK)
Für TOSLINK-Lichtleiterkabel (mögliche Länge je nach
Qualität/Fasertechnologie bis zu 10m).
Bitte beachten Sie:
Prinzipbedingt ist die TOSLINK-Verbindung mechanisch leider recht fragil und stör-
anfällig und daher nur für kurze Kabelwege gut geeignet.

3.4 Digital Thru (XLR)
Das Signal des ausgewählten Eingangs wird hier 1:1 wieder
ausgegeben, Sinn ist das Durchschleifen des Signals auf den
zweiten Lautsprecher für die Stereowiedergabe.
Bitte verwenden Sie nur echte AES/EBU-Digitalaudio-Kabel,
symmetrisch und mit 110Ohm Wellenwiderstand (kein normales
XLR-Mikrofonkabel) und vermeiden Sie es, Kabel zu verlängern
oder zu stückeln.
Bitte beachten Sie:
Stecken Sie nie ein Kabel mit einem Digitalsignal in einen analogen XLR-Eingang
oder umgekehrt!
3.5 Word Clock In
Hier lässt sich eine studioübliche WordClock anschließen,
die zum einen die gleiche Frequenz haben muss wie die Ab-
tastfrequenz (Samplerate) des digitalen Audiosignals und
zum anderen synchron zu dieser getaktet sein muss.
Standardmäßig ist der Eingang terminiert. Sollte dies nicht erwünscht sein (weil
extern terminiert wird und/oder die WordClock durchgeschliffen werden soll zu
einem weiteren Gerät), kann die Terminierung mit einem Jumper auf der Unterseite
der Baugruppe deaktiviert werden.
Wir empfehlen jedoch immer die direkte Einzelverbindung von einem WordClock-
verteiler zu jedem Gerät, weil das Weiterschleifen und externe Terminieren des
WorldClocksignals (immer am letzten Gerät) BNC-T-Stücke und BNC-Abschlusswi-
derstände erfordert und damit störungsanfälliger ist.
Kabel: 75Ohm-Coaxialkabel mit BNC-Steckverbindern (als „WordClock-Kabel“ im
Handel erhältlich).
