Many AV-Systems consist of a multitude of individual components. To avoid the necessity of switching them
on and off before and after every use, many manufacturers have equipped their devices with what is
known as “POWER CONTROL” circuit or “TRIGGER”. This kind of remote-controlled standby circuit is
used primarily for preamplifier and power amplifiers. Particularly for preamplifiers and main amplifiers
this kind of remote standby control is utilized, as power amplifiers are often placed far from other devi-
ces near the speakers. To employ these functions, direct or indirect cable connections must be made bet-
ween the preamplifier (or integrated amplifier) and all the devices which support this function. The
“POWER CONTROL” function operates in such a way that each switching on or off of one device in the
system (usually the preamplifier) automatically brings about the switching on or off of all the connected
devices which support this function. Please keep in mind that all devices which respond to the power con-
trol are not disconnected from the mains network when switched off. They are set to a standby state inste-
ad. For connecting cables, two-core cables with 3.5 mm jack plugs (mono) are used. For each connecti-
on between two devices one of those cables is needed.
If you don't wish to use this function or if the other components do not support it, all you have to do is
leave out these cable connections.
The SV-236MK is equipped with two output connectors for the power control. Here, the switching signal
generated by the amplifier is available for other components of the system. Two HiFi components that are
able to react to the power control signal can be connected directly to the amplifier's power control out-
puts (15). If more than two devices, which can be controlled, are to be connected, then it is necessary to
make the power control connection between the amplifier and these further devices through the outputs of
the two devices which are connected directly. For that reason, every HiFi component that accepts power
control signals is also equipped with a power control output. Thus, in theory it is possible to provide an
infinite number of HiFi components with the power control signal. This approach, to loop a signal through
a chain of components, is commonly referred to as “daisy chaining”.

CONNECTION OF TWO ADDITIONAL
MAIN AMPLIFIER CHANNELS
You only need the “PRE OUT” sockets (12) if you want to use a separate stereo amplifier or two mono
amplifiers to supply two additional loudspeakers. This makes sense if you intend to use two more loud-
speakers for stereo music playback, for example in a separate zone (another room of your home). These
loudspeakers are then connected to the speaker outputs of the additional amplifier(s). The amplifier out-
put connections “PRE OUT” (12) must be connected with the input connectors of the main amplifier, in
most cases labelled “INPUT”, “POWER AMP IN” or “MAIN INPUT”.

Instead of the stereo main amplifier shown here you can alternatively use two mono main amplifiers.
