What to do if there is hum or ground noise:
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 setting 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 common outlet box or power conditioner unit to reduce the possibility for ground current noise being induced into the audio signal path.
Front Panel Indicator Lamp
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 shorted together or connected to a ground. When you are certain that the loud- speaker cabling is correct then power the unit ON again and insure that the Blue lamp is lit and that music will play.
Fuse Protection
There is internal fuse protection in the amplifier. If the power switch is in the ON position, the power cable is con- nected to a functioning power outlet at the correct voltage and the Blue lamp is not lit, this indicates that the internal fuse may have blown. If this occurs contact your dealer, distributor or Bel Canto for service. There are no user replaceable fuses or other parts. Opening the chassis will void your warranty.
