and also features an MP3 player with USB port
and memory card slot, a Bluetooth receiver and
an FM radio .
4 Setting up the Amplifier
The amplifier is designed for installation into
a rack (482 mm /19”); however, it can also be
placed on a table . In order to ensure sufficient
cooling of the amplifier, air must always be able
to flow freely through all air vents .
4.1 Installation into a rack
For rack installation, the amplifier requires 1 RS
(1 rack space = 44 .45 mm) . The front plate is
not sufficient for fixing the amplifier safely;
additionally use lateral rails or a bottom plate
to secure the amplifier .
The hot air given off by the amplifier must
be dissipated from the rack; otherwise, heat
will accumulate in the rack which may not only
damage the amplifier but also other units in
the rack . In case of insufficient heat dissipation,
install a ventilation unit into the rack .
5 Connection
Prior to connecting /disconnecting, switch off
all units concerned .
1) For the connection of a
microphone
, use
the jack MIC (2): connect the microphone
via a 6 .3 mm plug or an XLR plug .
2) For the connection of
stereo audio sources
with line signal level
(e . g . CD / MP3 player,
tape deck, radio, mixer, PC), two inputs are
available:
– 3 .5 mm jack AUX (3);
when this jack is connected, the combi-
nation “MP3 player / FM radio / Bluetooth
receiver” will be muted .
– RCA jacks LINE IN (10);
L (white) = left, R (red) = right
3) The stereo connections PRE OUT and AMP
IN (11) can be used to insert an
audio pro-
cessing unit
(e . g . equalizer, effect unit):
The signal, after the control VOLUME (8),
will be routed to the audio processing unit
via the output PRE OUT and returned to the
power amplifier of the SA-130DMP via the
input AMP IN .
a) Remove the two jumpers (one each for
the left channel and the right channel)
that interconnect the output PRE OUT
and the input AMP IN .
2 Safety Notes
The unit corresponds to all relevant directives
of the EU and is therefore marked with .
WARNING
The unit uses dangerous mains
voltage . Leave servicing to
skilled personnel and do not
insert anything into the air
vents; inexpert handling may
result in electric shock .
•
The unit is suitable for indoor use only . Pro-
tect it against dripping water, splash water
and high air humidity . The admissible ambi-
ent temperature range is 0 – 40 °C .
•
Do not place any vessels filled with liquid on
the unit, e . g . a drinking glass .
•
The heat generated inside the unit must be
dissipated by air circulation; therefore, never
cover the air vents .
•
Immediately disconnect the mains plug from
the socket
1 . if the unit or the mains cable is visibly
damaged,
2 . if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3 . if malfunctions occur .
In any case the unit must be repaired by
skilled personnel .
•
Never pull the mains cable to disconnect the
mains plug from the socket, always seize
the plug .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .
•
No guarantee claims for the unit and no li-
ability for any resulting personal damage or
material damage will be accepted if the unit
is used for other purposes than originally
intended, if it is not correctly connected or
operated, or if it is not repaired in an expert
way .
If the unit is to be put out of oper-
ation definitively, take it to a local
recycling plant for a disposal which
is not harmful to the environment .
3 Applications
The stereo amplifier SA-130DMP is suitable for
a wide range of applications, e . g . in bars, func-
tion rooms and offices . It provides connections
for a microphone and two audio sources with
line signal level (e . g . mixer, CD / MP3 player)
