Feed-Forward Compression

The signal entering the compressor is split: one copy goes to the output (though the VCA), while

the other is fed forward to the VCA via a sidechain circuit. See the image below:

Sidechain High Pass (SC-HP)

As explained in the Feed-Forward Compression section above, the input signal is fed to the

VCA. Generally, the more energy you have in the sidechain, the more compression you get; but

if you apply a high-pass filter to remove low energy from the signal, the result will be less energy

when low-frequency energy is present, hence less compression. In bass guitars, for example,

the abundance of low energy entails lots of compression; but if a high-pass filter is applied on

the sidechain, the VCA will identify less energy on the low bass notes than there is in the actual

input signal and will therefore attenuate the signal less, allowing more low frequencies.

1.5 Components

WaveShell technology enables us to split Waves processors into smaller plugins, which we call

components. Having a choice of components for a particular processor gives you the flexibility

to choose the configuration best suited to your material. dbx 160 includes the following

components:

• dbx 160 Mono

• dbx 160 Stereo
