trim levels at zero

[godfrey]

Hi,
not sure if I'm doing something wrong but here goes: I wanted to record a track from a cd player onto the Korg D888 .I tried to fade in the track by starting the trim knob at zero and then gradually increase it. However with the trim pot at "zero" (all the way counterclockwise), I was getting signal from the player. It seemed like whatever I did, I couldn't get no signal coming in from the portable cd player-there was always some of the song coming through with the trim pot at zero and the fader at zero.
Any suggestions?
Thx
G
