I didn’t really seek out this little half-rack unit. It found me. the fellow who was selling the ADA Delay had this for sale as well. I got it for $20. I wasn’t really interested in it but I figured if anything I could reuse the box. I’ll give it a shot one day in the studio and see how it goes.
I don’t have a picture of this thing, but I found a funky line drawing of it in the manual.
From the manual:
The 563X Silencer contains one channel of single-ended, one step noise reduction for sources that have a continuous, unchanging hiss “floor”. For cleaning up program signals over this background noise, this very fast sliding-filter design is generally unobtrusive and remarkably effective, whether the his is a little or a lot.
Filter: 2nd-order, minimum phase design topology. Operates 1.3-38kHz depending on setting
Frequency Response: 20Hz – 20kHz +/-1.5 db on high-level pink noise
Acquired: 2010
Im interested,How much are you asking?
