Ducking - Alesis CLX440 Reference Manual

Ducking

Ducking is often used when doing voiceovers. It allows
background music to automatically be turned down whenever a

• Ratio set for 6:1
• Knee set for Soft
• Peak/RMS set for Peak
• Attack set around 9 o'clock
• Release set around 2 o'clock
Plug the announcer's mic into the mixer, and feed that mic to the
CLX-440's Sidechain in. When the announcer speaks, the music
will duck down (turn the ratio up to duck it even lower). When
he finishes speaking, the music will fade back up at a rate set by
the Release knob.
