Never Connect Either the Positive or Negative Speaker Output to Any Ground Contact!
Connecting any Speaker Output on the M300/S300 to Ground will cause the amplifier to go into protection
and could damage the amplifier and void the warranty.
• Power Switch: Power is on when the switch is
toggled to the I position and off in the O position.
• 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.
• Input Connections and RCA/XLR switch: When
using RCA cables for the input ensure 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.
• Do not connect both XLR and RCA cables to
the inputs!
• Output Connections: Attach your loudspeaker to
the output connectors. Be sure that the polarity
of each speaker is correct and the same for both
channels so that no phase inversion can occur.
Double-check all connections to and from the
amplifier. Power on the preamplifier in your system,
activate its Mute setting and then power on the
M300/S300
