The volume control is at maximum and output level too low
The volume control is too sensitive
20
Input and/or output sockets corroded
Check that the input and output RCA sockets on the rear of the SXH2 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 SXH2.
SXH2 is close to external interference
Check the proximity of your SXH2 to any possible source of EMI and/or RF interference, for example computers, televisions, amplifiers, speakers, etc. Ideally the SXH2 should be placed as close as possible to your source.
Earth loop in system
If your preamplifier and/or amplifier have an earth/ground lift switch, toggle it and check which setting sounds better. The signal ground of the SXH2 is isolated from earth by default, this means that there needs to be a connection to earth elsewhere in your system to alleviate hum.
Gain setting too low
Toggle the gain configuration switch at the rear of the SXH2 UP to the HIGH gain position. Make sure you turn down the volume before changing this setting.
Gain setting too high
Toggle the gain configuration switch at the rear of the SXH2 DOWN to the LOW gain position.
