COMPOSER PRO MDX2200
6.4 Voice-over compression (ducking)
The 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 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 com-
pression or ducking and is commonly used in discos, radio stations etc.
6.5 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 COMPOSER PRO MDX2200, 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.
7. INSTALLATION
7.1 Rack mounting
The COMPOSER PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at least an additional
4" depth for the connectors on the back panel. Be sure that there is enough air space around the unit for
cooling and please do not place the COMPOSER PRO on high temperature devices such as power amplifiers
etc. to avoid overheating.
7.2 Audio connections
The audio inputs and outputs on the BEHRINGER COMPOSER PRO are fully balanced. If possible, connect
the unit to other devices in a balanced configuration to allow for maximum interference immunity.
Critical applications may require to build up a transformer-balanced configuration for the output signals, so as
to avoid interference from ground loops or potential differences. For this purpose, we offer our high-quality
output transformer OT-1 as a retrofit kit.
