Your MA3.2S is equipped with both an RCA-cinch (2) and balanced XLR input socket (3) which can be used
as desired. Merely connect the pre amplifier with the relevant cable.
The output resistance of your pre amplifier, together with the capacitance of the cable leading to the mono
amp, form a low pass. When selecting your cable (particularly for long connection paths) you should choose
the lowest possible pre amplifier output resistance and lowest cable capacitance to allow non-influenced
transmission of the high frequency portions of the music signal.
2.7 Connection to the loudspeakers
Only use loudspeaker cable of good quality and with sufficient diameter to connect your loudspeakers to the
output clips (4). In case of doubt ask your dealer for the optimal cable for your loudspeaker. Take care of the
correct polarity when connecting. The red marked output clip of the MA3.2S must be connected to the red
loud speaker clip or marked with a plus sign. Right and left channels must be the same polarity.
If you are using banana plugs secure the outer parts of the sockets (by clockwise turning) before inserting
the pin. This will prevent rattling. On delivery you may find that plastic plugs cover the 4mm holes of the loud
speaker clips. These can be removed with a thin screwdriver. To be able to fully appreciate the tonal
qualities of the MA3.2S you should place the unit as close as possible to the loudspeaker. In this way
extremely short paths between the power amplifier and the loudspeaker, for the transport of electrical power,
are achieved. This saves you not only expensive loudspeaker cable but also makes the reproduction
insensitive to influences from the cable.
There are loud speakers that react through a short cable with tense, although weak, bass tones. This results
from long cables being used during the development of the loud speakers. You might say the cable is a
component of the frequency-dividing network and therefore responsible for the tone. This type of loud
speaker is best operated through long cables. In case of doubt ask your dealer.
2.8 Adjusting the tonal balance
The MA3.2S offers you the possibility to adjust the tonal characteristic from "bright" (very clear sound) to
"smooth" (warmer sound, a bit similar to tube amplifier). This is done using the selector (5) on the rear panel.
We recommend that both selectors are adjusted in the same way.
There is no "optimal" setting because listening to music is a matter of your individual taste. So find out by
yourself what's the right setting for you.
