The 5045 Primary Source Enhancer is a two channel device that is exceptionally useful at reducing feedback, effectively increasing the level a microphone can be raised before feedback occurs in a live sound environment by up to 20dB, without negatively impacting the sonic integrity of the source signal. With controls that are very simply laid out and generally require minimal adjustment, the 5045 is an invaluable tool for churches, stadiums, performance halls, or any venue where feedback is problematic.

The 5045 shares some traits with conventional “noise gates”, but operates with 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 tendency of a system to feed back. Most importantly, the 5045 does not require filtering and digital processing to achieve significant benefits.

Key features:

• All analogue design: The 5045 is built around custom transformers and doesn't introduce filtering and digital processing. The result of these analogue circuits is sonic performance that retains the integrity of the source material.
• Simplified controls: simplified use makes it ideal for environments without a full time engineer
• Depth control: sets how much attenuation is applied after the signal falls below where the “Threshold” is set. “0” implies zero attenuation and the 5045 won’t effect the signal gain
• Threshold: sets the level at which the PSE engages
• Time constant: sets how quickly the attenuation occurs
• RMS/peak: the 5045 tends to return to normal level from attenuation faster
