Hiss

Unplug the amplifier input to confirm that the

 

 

hiss is coming from the source or from a device

 

 

upstream. Erratic or popping noises indicate an

 

 

electronic fault in the offending unit. To keep

 

 

the noise floor low, operate the primary signal

boosting the signal further between the source

 

 

and the amplifier.
