Installation:
Unpacking:
Keep the packaging in case of transport or if you need to send it back for
repairs.
Positioning:
Place the amplifier in a well ventilated spot where there is no exposure to
sunlight or humidity. The amplifier must be positioned on its support legs to
allow good ventilation. Ensure that the surface is solid and stable.
Connection to the mains:
Ensure that the amplifier is connected to the mains via a properly installed
wall socket.

Connecting the loudspeakers:
Ensure that the amplifier is disconnected from the mains before connecting
the loudspeakers. Use a quality cable such as Oehlbach loudspeaker cable.
The loudspeaker wires can best be sealed using gold-plated banana plugs.
Take care that the polarity of the loudspeaker connection - red (+) and
black (-) - is correct.
Connecting music sources:
Use quality interconnect cables, cinch, such as Oehlbach.
A music source for one stereo channel.
It’s possible to connect a music source to the individual line-inputs of the
amplifier (fig.1, 6)
Set the accompanying jumpers on ‘IN’
One music source for several channels:
A single music source can be listened to via several different amplifier
channels (zones). To do this, connect the music source to the bus
connectors indicated L/R. (figure 1, 5)
Place the jumpers on L or R for the channels through which you wish to
listen to the music source.
AUX input:
The AUX is a common mono input. If you wish to use this input, set the
channel jumpers to AUX for all channels which receive their signal from this
input.
Volume control:
Each amplifier channel has its own volume control. Use a small screwdriver
to set the maximum volume of each channel individually.
Auto on:
If an audio signal is transmitted to the line input, the respective channel will
be started
.
