CONNECTION OF ONE
OR MORE POWER AMPLIFIERS
This preamplifier has two stereo preamplifier outputs with RCA connectors for the main amplifier channels. In
this way it is possible to drive four loudspeakers or bi-amp one pair of loudspeakers. The main amplifiers sup-
ply the system’s loudspeakers and the loudspeakers are connected to the outputs of these. Instead of each ste-
reo main amplifier shown here you can alternatively use two mono main amplifiers.
Connection of one pair of speakers:
In this case you will need two main amplifier channels, for example one stereo main amplifier. Connect
both sockets named “1” in the field “OUTPUT” with the RCA input sockets of the main amplifier channels
(often marked as “INPUT” or “POWER AMP IN”). For this you need RCA cables. Please pay attention not
to interchange right with left channels. The letters “R” and “L” indicate the correct correlation. You may
further use the SA-31MK preamplifier output marked with “2” for a headphone amplifier.
CONNECTION OF THE SOURCE EQUIPMENT
Connect the outputs of the source appliances to the inputs “S1”...”S6” (11) of this preamplifier. You can con-
nect up to six devices with analogue stereo high level output such as a CD player in order to provide the audio
signals of your input sources to the system. The output sockets on the source equipment are usually indicated
by “Line Out”, “Audio Out” or “Front Out”. You will find information about ways to connect source equipment
in their operating manuals. The audio inputs “S1”...“S6“ (11) represent electrically equivalent standard high
level inputs with RCA connection. They have an identical function and differ only in name.

CONNECTION OF A RECORDING DEVICE
If you want, you can use the RCA sockets “REC OUTPUT” (12) on the back of the appliance to connect
an analogue stereo recording device (e.g. CD recorder, cassette recorder etc.) or another appliance that
is intended for receiving the unchanged, fixed stereo output level (line level) from the signal source selec-
ted on the amplifier at any given time. The output level is independent from the volume and tone settings
(BASS, TREBLE, TONE, LOUD).

General hints:
To use a record player you need a so-called phono preamplifier (also called an equaliser preampli-
fier), which is installed in the signal path between the record player and one of the high-level inputs.
Some models of record player already include this preamplifier and can be connected directly. You
will find further information in this appliance’s operating manual.
The stereo sound of appliances that use output connectors other than RCA (DIN plugs, jack plugs) can
often also be used with the aid of adaptors.
Connect this signal output to the signal input (“LINE IN”, “TAPE IN” or “REC IN”) on the recording appliance
using RCA cables. Please note that some recording equipment can have a slightly detrimental effect on the
audio signal quality. Some recording devices have rather low input impedance, which can slightly alter the
input signal voltage. For maximal music enjoyment we recommend that you connect to the “REC” terminal only
for as long as the recording is actually being made.

Also select this type of main amplifier connection if you want to connect one speaker pair for bi-wiring.
Connection of two pairs of speakers:
Four main amplifier channels are required in this case, e.g. two stereo main amplifiers. Connect both
sockets named “1” in the field “OUTPUT” with the RCA input sockets of the main amplifier channels for the
first pair of speakers. Additionally connect the two sockets of the RCA combination marked with “2”
within the SA-31MK “OUTPUT” terminal area with the RCA input jacks of the main amplifier channels for
the second pair of speakers. The input jacks of main amplifiers are often marked as “INPUT” or “POWER
AMP IN”. Please pay attention not to interchange right with left channels. The letters “R” and “L” indicate
the correct correlation. Your specialist dealer will advise you of this on request.
