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 manu-
facturers have equipped their devices with what is
known as "POWER CONTROL" circuit or "TRIG-
GER". 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 pre-
amplifier) 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 discon-
nected from the mains network when switched off.
They are set to a standby state instead. For connec-
ting cables, two-core cables with 3.5 mm jack plugs
(mono) are used. For each connection between two
amplifier, preamplifier etc.
A theoretically infinite number of devices may be served with the switch impulses from a transmitting devi-
ce. To this end, on most devices one of the two "POWER CONTROL" connectors may be used as a signal
input and the other as a signal output. This method of passing on the signal via the devices' inputs and
outputs and of thereby chaining them is also known as "daisy chaining".

devices one of those cables is needed.
The CD-400 has one input socket (INPUT) and one
output socket (EXT) for power control (13). One out-
put on the transmitting device (integrated amplifier,
preamplifier or a device that passes on the power
control signal), usually labelled "POWER CON-
TROL" or "TRIGGER", must be connected to the sok-
ket "INPUT". If the "POWER CONTROL" cable is
connected to this player, the second jack connector
(EXT) serves to pass on the switch signal (for example
to the main amplifier) or it remains free. This CD play-
er cannot generate the switching signal for other
components on its own!
If the CD-400 is to be switched on/off automatically
with the preamplifier or integrated amplifier, then the
cable connections for power control described below
must be made correctly and the "POWER" switch
(13) must be moved to the switched off position. 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.
