CONNECTIONS FOR THE STANDBY CONTROL
(POWER CONTROL)
SP-996
preamplifier
z.B. 2. SP-996
power control cable
Attention:
Many devices which can be controlled by a swit-
ching signal (not preamplifiers or integrated
amplifiers), have two connectors which do not dif-
ferentiate between input and output. In this case
either of the two can be selected. Even some devi-
ces that transmit the switch signal (preamplifiers
and integrated amplifiers) lack this marking. In this
case it may be assumed that they both are signal
outputs.
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)!
If a POWER CONTROL cable is connected to the
back of the main amplifier, the main amplifier can
no longer be switched off with the “POWER” (1) but-
ton. This is true even in case the POWER CONTROL
cable is only connected to the SP-996 and the other
end of the POWER CONTROL cable is unplugged.
If the POWER CONTROL function is not desired, all
switch signal cables must therefore be removed!
Please note that automatic shutoff is not available if a
POWER CONTROL cable is connected to the
SP-996 (independent of the setting of the switch
“AUTO” (5)). In this case the SP-996 is supposed to
be controlled only by POWER CONTROL signal and
automatic standby would be nothing but disturbing.
In this way this main amplifier can respond to the signal of a
different unit and relay the signal to further components 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 CON-
TROL signal. This approach, to loop a signal through a chain
of components, is commonly referred to as “daisy chaining”.
If the SP-996 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-996 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 SP-996 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 chan-
nel) or it remains free. This main amplifier cannot generate the switching signal for other components on its own!
