I can hear a hum coming through my loud speakers
Input sockets and/or output binding posts corroded
Check that the input and output RCA sockets and binding posts on the rear of the SX60m are free from corrosion.
Interconnect cables damaged
Make sure that the integrity of your interconnect cables is sound and they are firmly connected to your source and the SX60m.
SX60m is close to external interference
Check the proximity of your SX60m to any possible source of EMI and/or RF interference, for example computers, televisions, amplifiers, speakers, etc. Ideally the SX60m should be placed as close as possible to your source.
