The 5045 Primary Source Enhancer is exceptionally useful at reducing feedback without negatively impacting the sonic integrity of the source signal, effectively increasing the level a microphone can be raised before feedback occurs in a live sound environment by up to 20dB. 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 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.

Features:
• All Analogue Design
The 5045 is built around Ruperts custom transformers and doesnt introduce filtering and digital processing. The result of these analogue circuits is sonic performance that retains the integrity of the source material.
• Simplified Controls
With a minimal control set and little reason to change settings, the 5045's simplified use makes it ideal for environments without a full time engineer.
• Depth
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
With the RMS/PEAK button pushed in, the 5045 tends to return to normal level from attenuation faster.
