Preamp Output
Level Trim – In this menu you can add a volume offset to the preamp output to compensate for gain differences between an external amplifier or subwoofer and the internal amplifier of the K-300i. The adjustment range is +/- 10dB.
Output Mode – The two choices are Variable or Fixed. In Variable mode the output level varies with the main volume control. In Fixed mode the output level is fixed to a standard line level output for driving devices with their own volume control.
Maybe your Output Mode for S2 is set to FIXED.
