Hum Reduction

Some signals have 60Hz hum no matter what you do. This

 

 

 

program de-emphasizes 60Hz and its harmonics without taking a

 

 

 

noticeable bite out of the sound.

Note for programs 16-20 and 22-26

Send the signal you want to equalize through Narrow Boosts 1-5 to find the frequency that may be most objectionable. Take note of that frequency for further editing or just set the DEQ230 to the Narrow Cut 1-5 program that matches the Boost program that emphasized the frequency range in question.
