CONNECTING THE PREAMPLIFIER
This main amplifier is equipped with a mono audio input “LINE IN” (3) on which the unit awaits the pream-
plified signal of an audio channel (for example “PRE OUT R” or “FRONT R”). This is the audio information
that the SP-998 provides for the loudspeaker.
Please note:
No source with a standard line level 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-998. 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”.
No source with a standard line level signal (“LINE OUT”) must be connected to this input. It is only intended
for preamplified signals (e.g. “PRE OUT”).
Connect the selected audio input connector to the output connector (example: “PRE OUTPUT R”, “PRE OUT-
PUT REAR R” or “OUTPUT R”) of a preamplifier. Summarizing, you will use an
RCA connection:
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. Ensure the volume of the respec-
tive preamplifier is not set too high before switching.
