CONNECTIONS FOR THE STANDBY CONTROL
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. To employ these functions, direct or indirect cable
connections must be made between 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 control are not disconnected from the mains network when switched off. They are
set to a standby state instead. For connecting 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 SV-500 is equipped with two output connectors for the power control. Here, the switching signal gene-
rated by the SV-500 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 (14).
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".

Many devices which can be controlled by a switching signal (not preamplifiers or integrated
amplifiers), 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 interconnec-
ted! All receiving devices must not be connected to more than one preamplifier or integrated
amplifier (directly or indirectly)!
