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-997 processes for one loudspeaker.
Please note:
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").
This audio input is equipped with two connectors with which the preamplifier can be connected as desired
by means of either the RCA or XLR connection on the SP-997. If your preamplifier offers both options, XLR is
preferable. Only one of the two connectors may be used at any given time. The setting of the switch
"XLR/RCA" determines which connector is currently used as the input. If the preamplifier is connected with
an RCA cable, then the switch "XLR/RCA" must be set to "RCA". If the preamplifier is connected with an XLR
cable, then the switch "XLR/RCA" (3) must be set to "XLR".
Connect the selected audio input connector of the SP-997 to the output connector (example: "PRE OUTPUT
R", "PRE OUTPUT REAR R" or "OUTPUT R") of a preamplifier. Summarizing, you will use an

Both "LINE IN" inputs can be connected to preamplifiers at the same time and in this way it is possible to
connect two preamplifiers simultaneously and toggle between the inputs. Make sure the volume of the respec-
tive preamplifier is not set too high before switching.
If the switch "AUTO" (4) 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.
