CONNECTIONS FOR THE STANDBY CONTROL
ally 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 control are not dis-
connected from the mains network when switched off. They are set to a standby state instead. For con-
necting cables, two-core cables with 3.5 mm jack plugs (mono) are used. For each connection 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 SP-20 is equipped with two output connectors for the power control. Here, the switching signal gene-
rated 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 outputs (6).
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".
SP-20
Many devices which can be controlled by a switching signal (not preamplifiers or integrated ampli-
fiers), have two terminals which do not differentiate between input and output. In this case either of
the two can be selected.
"POWER CONTROL" sockets of preamplifiers or integrated amplifiers must not be interconnected!
All receiving devices must not be connected to more than one preamplifier or integrated amplifier
(directly or indirectly)!
