1) Power Switch: Power is on when the
switch is toggled to the I position
and off in the O position.
2) Input Connections and RCA/XLR
switch: When using RCA cables for
the input insure that the RCA/XLR
switch is pressed in to the RCA
position. When using XLR cables
insure that the switch is out in the
XLR position. This will generally
insure ideal grounding and minimize
ground noise from interfering with
the audio signal.
3) Output Connections: Attach your
loudspeakers to the output connec-
tors, insure that the polarity of each
speaker is correct and the same so
that no phase inversion can occur.
Never Connect Either the Positive or
Negative Speaker Output to Any
Ground Contact!
4) IEC power cord jack: Connect a
heavy gauge power cord from
this jack to the wall power supply.
Note the power setting indicated
on the back of the amplifier before
connecting the power.
When all connections to and from the
amplifier have been made then double
check everything, insure that the pre-
amplifier is powered on and set to a
Mute setting and power on the S300.
