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 COMPOSER 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 COMPOSER 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 COMPOSER 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 Peak Limiter sections are switched off. The bass guitar track is connected
to the audio chain of the Behringer COMPOSER 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.
