Installation - Monacor SAM-2 Bedienungsanleitung

high air humidity and heat (admissible ambient
temperature range: 0 – 40 °C) .
•
Do not place any vessel filled with liquid on the
unit, e . g . a drinking glass .
•
When the module has been installed, the heat
generated in the speaker cabinet is carried off by
the cooling fins (1) . Therefore, never cover the
cooling fins . Never place the cabinet directly on
a wall; always keep a sufficient distance .
•
Do not operate the module or immediately dis-
connect the plug from the mains socket
1 . if there is visible damage to the module or to
the mains cable,
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 when disconnecting
the mains plug from the socket, always seize
the plug .
•
For cleaning only use a dry, soft cloth; never use
chemicals or water .
•
No guarantee claims for the module or liability
for any resulting personal damage or material
damage will be accepted if the module is used
for other purposes than originally intended, if it
is not correctly installed, connected or operated,
or if it is not repaired in an expert way .
If the module is to be put out of opera-
tion definitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment .
3 Applications
The insertion module SAM-2 is a fully assembled
200 W power amplifier with integrated power
supply unit designed for installation into 4 Ω or
8 Ω speaker cabinets . Due to the integrated 18 dB
subwoofer crossover network, an active subwoofer
system can be created . The module and the speaker
connected are protected by a 24 dB subsonic filter
and comprehensive protective circuits .
It is the particular advantage of SAM-2 that
it can be placed anywhere in the room as a fully
assembled active subwoofer . Level and phase
controls allow optimum matching to the satellite
speakers .

4 Installation

WARNING
During installation, the module
must never be connected to the
mains voltage!
1) For installing the module into the speaker cabi-
net, saw a cutout of 155 × 340 mm . If the front
panel is not recessed, the required mounting
depth is 85 mm .
2) Only connect speakers or speaker systems with
a total impedance of at least 4 Ω . Use push-on
terminals to connect the speaker to the connec-
tions OUT+ and OUT− on the top left of the PCB
of the power amplifier (see page 35) . Observe
the correct polarity, i . e . connect the positive
pole of the speaker to the contact OUT+ .
3) Use ten M4 screws to screw the module to the
cabinet .
5 Connection
Always switch off the active speaker system prior
to making or changing any connections .
5.1 Inputs
The module SAM-2 is equipped with two inputs:
1 . The RCA jacks LINE IN (14) for signals with line
level for connecting e . g . preamplifier, mixer,
equalizer, effect unit, etc .
2 . The binding posts HIGH LEVEL INPUT (13) for
connection to the speaker outputs of a power
amplifier .
Important: If the binding posts are used, the out-
put power of the power amplifier connected must
not exceed 480 W per channel at 4 Ω speakers
or 240 W per channel at 8 Ω speakers, otherwise
there will be signal distortions due to overload .
Connection to the jacks LINE IN (14) is the easiest
and safest solution . The inputs HIGH LEVEL INPUT
(13) should only be used if no line signal is available .
Use speaker cables to connect these inputs to the
speaker outputs of a power amplifier .
Be careful when connecting
via the binding posts!
a . In case of power amplifiers with a higher out-
put power than indicated above, there will be
a hazard of contact with dangerous voltage at
the jacks HIGH LEVEL INPUT .
b . In case of accidental short circuit, the power
amplifier may be damaged .
c . Observe the correct polarity for connection: Con-
nect the corresponding positive pole (speaker
cable core with marking) to the red binding post .
