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 produc- ing hum by setting the preamplifier to a MUTE or Standby setting.

3)The design of the REF1000 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. If you choose to power your source and preamplifier components from a different AC supply than used for the REF1000 amplifiers, we recom- mend that you use a high quality bal- anced XLR cable driven from a true balanced XLR preamplifier output. We do not recommend that you resort to ‘cheater plugs’ or some other means to disconnect the power ground from the REF1000 as this may lead to dan- gerous operation and void the warran- ty.

Front Panel Indicator Lamp

The small blue LED lamp indicates that the power is connected to the REF1000 and that the power switch is in the ON position. If the amplifier detects a fault or short circuit in the output connec- tions 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 loudspeaker cabling is correct, power the unit ON again and insure that the Blue lamp is lit and that music will play.

Fuse Protection

There is an internal fuse protection on the REF1000. If the power switch is in the ON position, the power cable is connected to a functioning power out- let 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.
