2.1 Important Information for set up
We reco\f\fend using high q\nuality XLR cables \nto guarantee opti\fal perfor\fance.
We reco\f\fend that you retain the original packaging, as it is the best  way to 
guarantee safe transportation should the need to do so arise.
 
Please note  that with the use  of the EA-SX e\fternal amp unit the option to retro\bt 
the SX monitors  with  the ADAM DA-SX 24 bit/192 kHz D/A converter will not be 
available anymore.
2.2  Connecting the external amp unit to the monitors
a)  Before connecting the loudspeakers to the 19” external a\fp unit \fake sure that 
your audio source is switched off.
\f)  Connect each \fonitor to one E\b-SX a\fp unit  by using one Speakon cable. You 
can order cables in either 5 or 10 \feter lengths fro\f \bD\bM \budio.  
	 Please note that in order to connect the monitors to the e\fternal amp unit you mus\Xt 
use the ADAM Audio ready-made Speakon cables.
Attention owne\fs of the S5X-H\b 
You will find two Speakon  jacks on each \fonitor that have to be connected to 
one E\b-SX a\fp unit per \fonitor. Please \fake sure you do not cross the two 
cables while connec\nting the\f to the  external a\fp unit. The respective Speakon 
jacks on both the \fonitors and the external a\fp unit are labelled with Speakon 1 
and Speakon 2 and have to be connected correspondingly.
c)    Connect your \fixing desk/D\bW to one E\b-SX per \fonitor channel using the XLR 
connector on the back panel of the external a\fp unit.
d)  Check if the specified voltage \fatches the voltage of the power supply you use. If 
this is not the case do not conne\nct the E\b-SX to a power source! Please contact 
your local dealer o\nr national distributor. 
If the voltages \fatch, use the included power cables to connect the E\b-SX to the 
\bC socket.
e)    Power on the external a\fp unit at the back panel first and then at the front    
  (Standby switch). 
f)    Turn on your audio source and adjust the volu\fe carefully.

EA-SX Manual / English
3.1 
General recommendations
Please \fake sure that there are no obstacles in the way fro\f  the \fonitor to your ears. 
You should be able \nto see the speakers co\fpletely. 
The loudspeakers should be aligned\n with the listener’s position.
Please note that vibrating parts of nearby objects can \fask \nthe sound.
Mechanical adjustments: If you plan to \fodify the speaker cabinet (e.g. dr\nilling 
holes), please cont\nact us before doing so. Usually, we will handle your warranty 
obliging.
3.2  Flush mounting the \cmonitors
Should  you  consider   to  flush  \fount  your  \fonitors,  this  would  bring  so\fe  acoustical 
benefits.  Cabinet  edge  diffraction  and  also  low  frequency  reflections  that  would 
nor\fally occur fro\f the wall behind the speaker can be avoided that way. The result is  
an i\fproved \fid and low frequency response.
Regarding the orientation of the \fonitors please \fake sure  the  acoustical axis of  each 
\fonitor  points  directly  to  the  listening  position.  In  larger  control  roo\fs   the  \fonitors 
should be  angled in the vertical plane so that the acoustic axis  \feets in the \fiddle of 
the standing and seated listening position. In the horizontal plane  the \fonitors should 
be   placed  according  to  the  standard  stereophonic   (60°  between  L/R  channels)  or 
\fultichannel (ITU-R BS.775\n-1) setup reco\f\fendations.
Fo\f  fu\fthe\f  info\fmation  on  installation  we  \fecommend   contacting  an  acoustics 
specialist o\f  a p\fofessional \feco\fding studio design/const\fuction company.
3. Speaker Installation

4.1  The front control panel
On the front of the a\fp unit you will find a contr\nol panel that allows detailed 
fine-tuning of your loudspeakers to your particular roo\f acoustics and personal 
listening preferences. The following tips are intended to assist you at using the 
controls in the best \fanner. 
Please note that using the controls \fay have a great i\fpact on the overall sound 
characteristics  of  your  loudspeakers.  We  reco\f\fend  using  the  controls  with   
ut\fost care and only after several audio tests with fa\filiar recordings.
4.2   Stand\fy switch and LEDs
While the \fain power switch can be found on the rear of 
the external a\fp unit, there is also a switch for power on/ 
standby on the front panel. In standby \fode, the switch glows 
orange, in power on \fode it glows green.
To the right of the standby switch you can find 
two LEDs:
•  In case of an overload, the OL LED will flash  red. The protective circuit  will safe 
your speaker fro\f da\fage. 
•  The D/A LED on the E\b-SX is without function as the D/\b converter option is not 
available with the use of the external a\fp unit.

4.3 
Input Controls
There are two different  controls to regulate the overall input
sensitivity:
•  One control allows for coarse settings  fro\f -20dB to +8dB. The 
control works in 4dB steps.
•  The other control is intended for \bne tuning in 0.5dB steps, 
ranging fro\f -1.5dB to 2dB. 
4.4  Bass Controls
There are two different  controls to regulate the lower 
frequencies:
•  The EQ 80 Hz control is a bell equalizer to boost bass response.
•  The 6  kHz control is a shelf filter that allows to progressively 
raise or lower the frequencies above 6 kHz (see Fig.).

\bll \bD\bM products are designed and \fanufactured  to the highest quality 
standards.  However, if any proble\fs with your speaker occur, we reco\f\fend 
to proceed as follows:
5.1 P\foblem: The LED shows nor\fal operation (green) but there is either no 
or on\fy a d\bstorted aud\bo s\bgna\f.
If both (all) speaker channels are affected, the reason can probably  be 
found within the signal path. If only one speaker is affected, the proble\f 
will probably be within  this speaker or the external a\fp unit.
a)  Check the wiring. 
Is the cable defective? \bre all cables connec\nted correctly?
\f)  Check the signal path.
Interchange the cables of both external a\fp units. Does the  proble\f 
change with one of the cables?
Connect the external a\fp units as directly to the signal source as pos-
sible. Is another part of the signal path (e.g. \fixer, subwoofer) defective?
If the answer to all these questions is ‘no’, the proble\f is being cause\nd 
by the loudspeaker or the external a\fp unit with the ut\fost probability.
If the answer to at least one of these questions is ‘yes’, there will prob-
ably be another defective device within the signal path.
5.2  P\foblem: You hear paras\bt\bc  no\bses (like  hu\f\fing, buzzing, so\nughing,   
cracking).
Please disconnect t\nhe signal cables.
If the noises disappear\n, check the signal path.
If the noises can still be heard, check for other electrical devices close to 
the speakers (\fobile phones, s\nwitching power supplies, etc.). If there is 
no interfering device the speaker will probably cause the proble\f.
