COMPOSER PRO MDX2200
technique is required, the attack and release times can also be manually adjusted.
The experienced user will be in a position to specify parameters while in bypass mode and thus realize the
effect before the unit is actually switched into operation. This is important in live situations, where a signal
needs to be managed efficiently by the engineer, without the convenience of continual A/B comparison.
4.3.2 The COMPOSER PRO as a sound effects unit
In the early 1960s, musicians began looking at the recording process as a way to create new sounds. The
pumping effect which had been avoided by earlier engineers suddenly became fashionable and was utilized as
a creative tool, laying the groundwork for many of the sounds which are now considered indispensable in
contemporary music. The compressor is used in this role because you can hear it working, and control of the
dynamic range is of secondary importance.
The BEHRINGER COMPOSER PRO, with its extensive range of functions, is well suited to this application.
Sound effects of this kind can be achieved using extreme settings. To achieve this, set the THRESHOLD
control to a fairly low level, the RATIO control to almost maximum and use the ATTACK and RELEASE
controls to obtain the desired effect. Experiment with all the controls in order to get a feel of their function!
4.3.3 The muffling effect of a compressor
Quite often, compressors are sometimes accused of muffling the sound, whilst at the same time reducing the
dynamics. This fact should be investigated further. Bass frequencies contain most of the energy within music
and therefore cause the compressor to reduce the overall dynamics. If the music also contains high frequen-
cies along with the bass frequencies, these are also reduced in level. This is the reason why: in an extremely
compressed recording of drums, the cymbals and high-hats are acoustically swamped by the sound of the
snare or the bass drum. The same effect is experienced when processing reverberated or ambient sounds. The
solution commonly used to this basic problem is either to reduce the compression ratio or to slow down the
attack time, so that the increasing high frequency transients pass through the compressor unhindered before
the compressor takes effect.
The COMPOSER PRO MDX2200 offers a solution to this problem that is by much more elegant. The SC
FILTER switch allows you to activate a high-pass filter in the control signal path of the compressor. This filter
makes sure that midrange and treble range frequencies are taken into account to a greater extent, and that a
low-frequency signal triggers less compression than a midrange/treble signal of comparable level. A major
advantage of this design can be seen in the fact that the frequency response of the overall signal is not modified
below the threshold adjusted with the Threshold control.
In pop music the dynamics of both kick drum and bass guitar are usually processed individually. The side-
chain filter is therefore ideally suited to apply overall compression in the mix-down, to compress the music
while increasing its loudness, but without having to accept the drawbacks described above.
Please note that we offer a whole series of high-grade equalizers and enhancers/exciters, which are perfect
tools to give any dynamics-processed signal the finishing acoustic touch. Please ask for detailed information!
4.4 Peak limiter section
As a section of its own and independent of the remaining control functions, the peak limiter enables you to limit
the maximum peak level on the COMPOSER PROs output. It has been designed for use in combination with
the compressor section. Independently of all compressor functions, you can protect subsequent devices against
signal peaks, short-time overload and excess modulation (radio stations, etc.).
