7.3 Anticipated Compression
If you feed the audio signal directly into the SC RETURN input and send the audio signal through a delay before
the audio input, the Behringer AUTOCOM PRO can anticipate the need for gain change. With experimentation,
the effect can create a zero attack time at a given frequency. Additional delay beyond this zero attack time
will produce a special sound effect, similar to the dynamic envelope inversion you may already be familiar with
from reverse tape playback.
7.4 Voice-Over Compression (Ducking)
The Behringer AUTOCOM PRO can be used to automatically reduce music to a background level, when an
announcer is speaking through a microphone. For this purpose, the Behringer AUTOCOM PRO is used as an
automatic fader and is controlled by the announcers microphone, which is connected to the SC RETURN input
via a preamplifier. The music output and the announcers voice, are then mixed. This application is known as
voice-over compression or ducking and is commonly used in discos, radio stations etc.
7.5 Triggering Additional Sounds From A Rhythm Track
This technique is used to give a rhythm track more punch. For this purpose, only the Expander/Gate section
is required and the Compressor and Dynamic Enhancer sections are switched off. The bass guitar track is
connected to the audio chain of the Behringer AUTOCOM PRO, while the bass drum is connected to the SC
RETURN input. By activating the SC EXT switch, the bass guitar is now triggered by the bass drum.
Another application allows the sound of the bass drum to be supported or extended by other instruments
(synthesizers etc.), where the bass drum is used to trigger a new sound, which is then mixed into the track.
