2 Safety Notes
The unit corresponds to all required directives of the
EU and is therefore marked with .
It is essential to observe the following items:
G
The unit is suitable for indoor use only. Protect it
against dripping water and splash water, high air
humidity, and heat (admissible ambient temperature
range 0 – 40 °C).
G
Do not place any vessels filled with liquid, e. g. drink-
ing glasses, on the unit.
G
The heat being generated in the unit must be carried
off by air circulation. Therefore, the air vents at the
housing must not be covered.
G
Do not set the unit into operation, or immediately dis-
connect the mains plug from the mains socket if
1. there is visible damage to the unit or to the mains
cable,
2. a defect might have occurred after a drop or simi-
lar accident,
3. malfunctions occur.
The unit must in any case be repaired by skilled per-
sonnel.
G
Never pull the mains cable to disconnect the mains
plug from the mains socket, always seize the plug.
G
For cleaning only use a dry, soft cloth, never use
chemicals or water.
G
No guarantee claims for the unit and no liability for
any resulting personal damage or material damage

Important for U. K. Customers!
The wires in this mains lead are coloured in accor-
dance with the following code:
green/yellow = earth
blue = neutral
brown = live
As the colours of the wires in the mains lead of this
appliance may not correspond with the coloured
markings identifying the terminals in your plug, pro-
ceed as follows:
1.The wire which is coloured green and yellow must be
connected to the terminal in the plug which is
marked with the letter E or by the earth symbol , or
coloured green or green and yellow.
2.The wire which is coloured blue must be connected
to the terminal which is marked with the letter N or
coloured black.
3.The wire which is coloured brown must be con-
nected to the terminal which is marked with the let-
ter L or coloured red.
Warning – This appliance must be earthed.
3 Applications
This amplifier is suitable for HiFi applications or for PA
applications of smaller rooms.
Due to its compact dimensions and the mounting
facility it can e. g. directly be fixed to a speaker system.
Thus, a speaker system becomes an active system.
The amplifier is equipped with a protective circuit
against short circuit and overheating.
4 Mounting and Connection
As suggested in the drawing, the amplifier may be
mounted via its mounting brackets (e. g. to the rear
side of a speaker system next to the terminals).
Air must be able to move freely through the cooling
fins at the rear side of the unit and the air vents in the
housing to ensure a sufficient cooling.
4.1 Connecting the signal source
For connection of a signal source with line level (e. g.
CD player, mixer output, line output of a computer)
there are the following possibilities:
1) For balanced signals the XLR jack (3) is suitable
(configuration of the contacts
chapter 6).
2) For unbalanced signals the phono jacks (2) are suit-
able. When using both phono jacks at the same
time, the input signals are mixed. Therefore, a
mono signal is created when connecting a stereo
signal source.
If the unit is to be put out of operation defini-
tively, take it to a local recycling plant for a
disposal which is not harmful to the environ-
ment.
WARNING
The unit is supplied with hazardous
mains voltage. Leave servicing to
skilled personnel only and do not insert
anything into the air vents! Inexpert
handling or modification of the unit may
cause an electric shock hazard.
