ICM and Subsonic.

[BoyScout]

Thanks to both of you.
It´s clarified. I use the amp for music playback only.
Someone told me that Subsonic is suposed to increase the lower freqs., usefull when listening with very low volume, so i can keep both turned off.

No subsonic does exactly the contrary.

It cuts the very low frequencies, supposedly under 20Hz, however its roll off aspect affects frequencies a bit higher.

This is useful if you are listening to a warped vinyl, that way it would avoid your woofers to be slowly beating.

If you are only listening to digital sources that are correctly mastered it should not be very useful for you.

both ICM and Subsonic are permanently off in my system.

Thanks, Jean-Marie,
I thought the opposite, but i´ll keep it off anyway.
Cheers.
