The 5045 Primary Source Enhancer is a powerful audio processor that is able to reduce feedback without negatively impacting the sonic quality of the source material, effectively increasing the level before feedback by up to 20dB. With very simple controls, the 5045 is an invaluable tool for every situation and venue where feedback is an issue.

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.
