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 dialing 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
