CONNECTION OF THE POWER CABLE
Check that the electricity supply to your home is appropriate to the device. The required voltage and fre-
quency can be read on the back of the device beside the socket for the mains. If the electricity supply is
appropriate, push the inlet connector of the supplied mains cable firmly into socket for the mains on the
back of the device (7). Connect the other end of the mains cable to a mains socket.
CONNECTIONS FOR THE STANDBY CONTROL
Many AV systems or stereo audio 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 pri-
marily 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 (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 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 the SP-997 main amplifier is to be switched on/off automatically with the preamplifier, then the cable connections
for power control described below must be made correctly. If you don't wish to use this function or if the other com-
ponents do not support it, all you have to do is leave out these cable connections.
The SP-997 is equipped with one input connector and one output connector for the power control. Connect a Power
Control socket (named "POWER CONTROL OUTPUT" or "TRIGGER OUTPUT") of the controlling or relaying unit
with one of the POWER CONTROL sockets. If the POWER CONTROL cable is connected to this device, the second
jack connector serves to pass on the switch signal (for example to the main amplifier of the other channel) or it
remains free. This main amplifier cannot generate the switching signal for other components on its own!

In this way this main amplifier can respond to the signal
of a different unit and relay the signal to further compo-
nents of a system, if required. All other HiFi components
that accept POWER CONTROL signals are equipped
with one POWER CONTROL input as well as one
POWER CONTROL output in the same fashion. 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 compo-
nents, is commonly referred to as "daisy chaining".
