MULTICOM PRO MDX4400
In pop music the dynamics of both kick drum and bass guitar are usually processed individually. The sidechain filter is therefore ideally suited to apply overall compression in the mixdown, 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
5.3 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 MULTICOM PRO’s 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,

Fig. 5.3: IGC characteristic of the limiter section
The diagram illustrates the functioning of the IGC limiter. The solid graph represents the output signal, while the dashed graph above shows the input signal response. The areas between the graphs represent the amount of gain reduction (bright areas are “clipping areas”, i.e. signal peaks are radically cut off, dark areas show the effect of the program limiter). The limiter is activated when the adjusted threshold is exceeded for more than 20 ms, so as to limit audible clipping to a very short moment. About 1 s after the signals has dropped below the threshold again, the reduction is set to 0 dB, so that input and output signals are identical again (unity gain).

Tab. 5.3: Initial settings for the peak limiter section
The THRESHOLD control of the Peak Limiter sets the threshold level, so that subsequent units are protected from overloading. If the LIM comes on regularly or is on constantly, the OUTPUT control of the compressor section must be turned down, as this control sets the level of the signal, which is routed to the Peak Limiter section.
If this technique leads to an undesired drop in the overall level, it is recommended that you increase the compression: either, reduce the threshold level, or increase the compression ratio with the RATIO control. The OUTPUT control will compensate for a renewed drop in level.
