Chapter 7: Using The Compressor

DN540

28 Operator Manual

When LINK is switched on, the compressor sidechains of the linked channels are

combined by a true power law summer such that a single source panned from left to

right will not change the compression levels that have been applied to it.

Sidechain

For most applications the DN540 is triggered by the level of the incoming signal.

Sometimes it can be useful to use a different signal to trigger the compressor; this

signal is known as an “external sidechain”.

Each channel of the DN540 has a sidechain input for the compressor. In normal use,

the amount of compression or expansion is related to the dynamics of the input signal.

The sidechain allows the signal passing through the unit to be controlled by the

dynamics of another separate signal.

Particularly in the case of drums, a very reliable trigger can be obtained by taping a

contact microphone to the shell of the drum, using the clean signal it produces to

trigger the compressor. An example of this set up is shown below.

Connection to the sidechain input is made via the rear panel jack sockets, see

“Connecting the audio cables” on page 10.
