The small blue LED lamp indicates that the
power is connected to the amplifier and that
the power switch is in the ON position. If
the amplifier detects a fault or short circuit
in the output connections then it will go into
a protection mode and stop playing. If this
occurs toggle the power switch to the OFF
position and check the speaker cabling to
insure that no speaker output is either short-
ed together or connected to a ground.
When you are certain that the loudspeaker
cabling is correct then power the unit ON
again and insure that the Blue lamp is lit
and that music will play.

1) Check that the RCA/XLR switch is in the
correct position for the type of connection
being used.
2) Insure that the preamplifier or any source
components are not producing hum by set-
ting the preamplifier to a MUTE or Standby
setting.
3) The design of the amplifier reduces the
chance for ground loop induced hum but
we still recommend that you use shorter
interconnect cables to the preamplifier
and connect all power cables to a com-
mon outlet box or power conditioner unit
to reduce the possibility for ground cur-
rent noise being induced into the audio
signal path.
