dbx 463X Over Easy Noise Gate Expander


dbx 463X Over Easy Noise Gate Expander

This is a used piece and has some cosmetic wear and tear but otherwise works perfectly.


Vintage noise gate from dbx. The 463X is a 1/2U single-channel “Over Easy” noise gate / expander which can be linked to a second 463X to make a stereo gate, or to a  compressor

When linked to a 163X, the pair can act as a stereo noise gate or a stereo compressor, depending on which unit is selected as master. With one of each unit you have the option of stereo compression or gating

The 463X has an additional high-impedance (Hi-Z) input on the front panel ideal for use as a DI (direct injection) input. This makes the 463X ideal for use with noisy synths or guitar fx which might benefit from a subtle noise gate. The DI input has a level trim on the back panel and it has enough gain for synths, guitars or even high-impedance mics

The 463X is simple to operate: set the threshold with the threshold control, then dial in the amount of noise reduction (expansion) needed when the gate is closed. By dialling in a small amount of reduction – no more than 10 db – it’s possible to clean up noisy signals without the gating becoming obtrusive. Attack and release times are dependent on the slider position and on program material

The 463X also has a key input to operate the gate from an external signal. This works very well on keyboard pads keyed by a cowbell or other percussion instrument

The DBX 463X is a really simple piece of gear, that has a Hi-Z 1/4″ input in the front of it. It also has 1/4″ connections for input and output in the back of it, as well as for a few other features including for stereo coupling this with another one. It is rack mountable, but will only take up half of a single space. The only parameters that is has are for threshold and for setting your ‘downward expansion,’ which is basically setting the amount of gating that you’d like.
