Tab. 7.1: Initial settings for the De-Esser functions
Turn the THRESHOLD control anticlockwise until the GAIN REDUCTION meter shows an appropriate drop in
level. Now press the SC MON switch and adjust the equalizer corner frequencies (generally 6 - 10 kHz) by
monitoring, until it is within the range of the sibilance. Release the SC MON switch and recalibrate the
THRESHOLD control, so that the unit reacts only when the sibilant sound occurs.
Level compensation using the OUTPUT control is not necessary. Although the recommended attack and
release times for this function are proven, the time parameters can be adjusted if necessary to achieve
maximum results. The AUTO function should not be used.
7.2.2 Frequency Selective Filtering Of Unwanted Signals
Based on the set-up described in the de-esser section, the unit may also be used to eliminate rumble, hum
and equipment noise (air-conditioning systems, camera noise etc.). Using the SC MON switch, adjust the
frequencies of the equalizer to match the unwanted frequencies and use a peak filter with a high slope. Take
care to decrease the amplitudes of the unrequired frequencies. Proceed now as described in the previous
chapter 7.2.1 The COMPOSER PRO As A De-Esser. This will result in compression of the selected
frequencies and thus a decrease in the gain of the program material.
7.2.3 Suppressing Instruments During Recording
Another function of the Behringer COMPOSER PRO allows helpful correction of previously recorded material.
If, for example, an excessively loud bass drum needs to be suppressed, reduce all the equalizers frequency
bands above 150 Hz. This setting causes frequency specific compression, which reacts as soon as increased
energy is detected in this band. By increasing the threshold level, the compression can be made to react only
to loud pedal or stick actions. Generally, it can be said that relatively high threshold settings prevent the
overall sound from being impaired and lead to the compression of solo instruments or very loud sounds.
7.2.4 Emphasizing Musical Instruments During Recording
On the other hand, you can use the Behringer COMPOSER PRO to bring out an instrument solo or a lead
vocal in a cluttered mix. Using the SC MON switch, match the frequencies of the equalizer to the frequencies
of the instruments to be emphasized and for this it is best to use a notch filter with a high slope.
Please make sure that in this application, you only reduce the amplitude of the selected frequencies. The
compression results in a subjective decrease in the volume of the overall program material. Only the selected
frequencies coming from the equalizer remain uncompressed and are therefore perceived as being louder.
This inverse type of compression also helps to emphasize instruments during low level passages, so that
they become more pronounced.
