CONNECTIONS FOR THE STANDBY CONTROL
(POWER 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. Particularly for preamplifiers and main amplifiers
this kind of remote standby control is utilized, as power amplifiers are often placed far from other devices
near the speakers. 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 (usu-
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 SV-737 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 (20).
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".
