2. FUNCTION DESCRIPTION CONFIGURABLE AUDIO PATH audio chain processing FLT-EXP-COMP-GAIN-LIM configurable through the user to extend the possible applications of the device. EXP-FLT-COMP-GAIN-LIM Changing the audio chain means to move the filter block in one of four possible positions. EXP-COMP-GAIN-LIM The selection is to do by calling the CONFIG menu. -
Page 14: Remote Fader
2. FUNCTION DESCRIPTION REMOTE FADER If a fade is performed before the ACCENT, the compressor will try to increase the level as the fader decreases. Therefore the fade must be done after the compressor. ACCENT is supporting the performance of hand-fades by using a remote fader. -
