CONNECTIONS FOR THE ST NDBY 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 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 SP-332 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 com-
ponents 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 pos-
sible 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-332
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)!
