1) RCA Inputs
This is the most common audio input. If you are using the XJ-300ST as a mono
block (1-channel ampli
fi
er), connect to both RCA input terminals to get the fulll
300W output.
2) Speaker Outputs
To use the XJ-300ST as a stereo 2-channel amplifier, connect the right
speaker to the R+ and R- terminals. Then, connect the left speaker to the
L+ and L- terminals.
If using the XJ-300ST as a monoblock/1-channel ampli
fi
er, connect the
positive speaker wire to the L+ terminal and connect the negative speaker wire
to the R- terminal. Do not connect anything to the lower speaker terminals.
To use the XJ-300ST as a 2.1-channel ampli
fi
er (TRI-MODE), connect the
right speaker to the R terminals (R+/R-) and connect the left speaker to the L
terminals (L+/L-). Then, connect the subwoofer positive to the L+ terminal and
the subwoofer negative to the R- terminal.
3) +12V Trigger Input
Used when an external source is powering the XJ-300ST. For this to work, the
Signal Sense toggle switch in the front of the ampli
fi
er must be set to “+12V
TRIG.”
4) 110V/220V AC Selector
The XJ-300ST can operate in a 110-120V or 220-240V environment. The
ampli
fi
er should already be set to the correct voltage depending on your
region.
If not, make sure the ampli
fi
er is not connected to any power source. Set the
selector to the required power setting and replace the fuse to the proper rating
prior to connect the ampli
fi
er back to a power source.
