I found a previous thread on this subject where I posted the following:
1.Direct Gain- use a low setting , below -1.0 dB.( I use 0 dB.)
Direct Gain:
How much the level of the audio that travels the direct path from a speaker to the corresponding ear is supposed to be decreased.
2.Cross gain- not as important as direct gain to me, I use -6 dB
Cross Gain:
How much the level of the audio that travels the cross path from a speaker to the opposite ear is to be decreased.
3.HFA- I set this at -6dB, the least destructive to me.
High-Frequency Attenuation:
How much the upper frequencies of the cross path audio will be dampened. Note that the total level of the higher frequencies will be a combination of both this setting and the Cross Gain setting.
4.HFC- I set this at 2000Hz.
High-Frequency Cutoff
Decides at which frequency the cross path audio will start to be cut by the amount described by the High-Frequency Attenuation setting.
