The 5045 shares some traits with conventional “noise gates”, but operates on a different principle. One common aspect is that both reduce the gain during the absence of signal – or more specifically, both begin to attenuate when the level of a signal falls below a certain user-defined threshold. The 5045 senses when someone is speaking or singing into the mic and allows the signal to pass through, and senses when the person has stopped talking or singing and reduces the gain appropriately, which helps reduce the system’s tendency to feed back. Most importantly, the 5045 does not require filtering and digital processing to achieve significant benefits.
