Chapter 7: Using The Compressor

The DN540 is a dynamics processor that utilises premium quality, high precision components to achieve a high degree of accuracy and control. The DN540 has been designed primarily for creative use as front of house (FOH) or monitor. However, it is just as effective when used in the studio while broadcasting or recording. The DN540 processors offer, in a compact unit, control over the dynamic range for creative and corrective purposes.

Modes of operation

The compressor has the following two modes of operation, which are selectable via the AUTO pushbutton.

Manual mode (AUTO off) Linear type of compression, where the attack and release time constants can be adjusted manually (via the ATTACK and RELEASE control knobs). This provides a more advanced style of compressor operation, typically to produce creative effects.

Auto mode (AUTO on) RMS type of compression, where the attack and release envelope time constants are adjusted automatically, taking into account threshold and ratio settings relative to signal levels and transients.

Both of the compressor modes operate in either soft knee or hard knee.

Manual mode with soft knee (linear peak)

With the AUTO and HARD pushbuttons switched off, the compressor is peak sensing with manually adjustable attack and release envelope characteristics. The soft knee affects the attack shape, which noticeably slows the onset of compression. This can be particularly useful on drums to emphasise transients by giving them more punch, while retaining a good deal of artistic dynamic from the drummer.

The compressor normally sounds best on

applications that require slower attack time settings. If faster attacks are needed it is normally best to switch on the hard knee.
