DBX 904 LED Board Schematic
-o- Part of the The DBX 904 noise gate module for the 900 series rack. …. I poked around with a meter, and got about a .4v signal at the input. I started working my way back from the output, and found a non-polarized electrolytic capacitor that wasn’t passing any AC. So to test my theory, I removed C3– a 4.7uF non-polarized electrolytic cap– and replaced it with a pair of 10uF capacitors wired back-to-back, i.e., negative tied together, positive side out… and it works, passing a clean, gated signal! ….Brian Gilbert
Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal’s dynamic range. Compression is commonly used in sound recording and reproduction, broadcasting,[1] live sound reinforcement and in some instrument amplifiers….
