3.2 Emphasizing instruments

Conversely, you can also use your COMPOSER PRO-XL or

AUTOCOM PRO-XL to highlight solo instruments or vocal tracks

acoustically in a less than perfect recording.

Please note that in this application only the amplitudes of the

selected frequencies should be reduced in level.

Compression produces a subjective volume reduction of the

entire program material. Only those frequencies selected on the

equalizer will cause NO compression and thus they seem to be

emphasized acoustically. This inverse type of compression helps

you make instruments stand out even in low-level passages.

3.3 Time-delayed compression

If you feed the audio signal directly into the SC RETURN input

and at the same time route it to the audio input via a delay unit,

the dynamics processor will work anticipatorily. With a bit of

tweaking you can achieve zero attack effects for specific

frequencies. Longer delays produce an effect that is similar to an

audio tape being played back in reverse.

3.4 Voice over compression (ducking)

You can use the COMPOSER PRO-XL and AUTOCOM PRO-XL

to lower music to a low background level as soon as a speaker

speaks into the microphone. In this type of application the

compressor section functions like an automatic fader controlled

by the speakers microphone, which is also connected to the SC

RETURN input via a preamplifier. Music and microphone signal

are then mixed with the help of a console. This application is called

voice over compression or ducking, and is used frequently in

discotheques or radio stations.

3.5 Triggering additional sounds from a

rhythm track

This technique is used to give a rhythm track more punch by

synchronizing the rhythm instruments after recording. Only the

expander/gate section is required, the compressor and/or peak

limiter remain disabled. Insert the bass guitar track into the audio

path of the COMPOSER PRO-XL (or AUTOCOM PRO-XL), and

route the bass drum to the SC RETURN input. Activate the SC

EXT function to trigger the bass guitar with the kick drum, i.e. the

kick drum exceeds the expander threshold, allowing the bass guitar

signal to pass until the level has dropped below threshold again.

4. WIRING

Dynamics processors are usually inserted into the insert paths

of a mixing console, because their signals are not added to the

mix (unlike reverb or phaser effects, which are fed into the signal

path via the aux busses).
