CONNECTING THE PREAMPLIFIER CHANNEL
This main amplifier is equipped with a mono audio input “LINE IN” on which the unit awaits the preampli-
fied signal of one audio channel (for example “PRE OUT R”, CENTER or “FRONT L”). This is the audio infor-
mation the SP-996 processes for one loudspeaker.
General information:
No source with a standard line level output signal (“LINE OUT”) must be connected to this input. It is
only intended for preamplified signals (e. g. “PRE OUT”).
Connect the audio INPUT socket to one of the RCA output sockets of a preamplifier (e. g. “PRE OUT R” or
“OUTPUT R” if this main amplifier is supposed to play back the right channel signal of a stereo system).
If the switch “AUTO” (5) is set to “ON” and no cable is connected to both “POWER CONTROL” sockets
this main amplifier switches back into standby automatically 30 minutes after a signal has been detected
for the last time at this “LINE IN” (3) socket.
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.
