Rupert Neve Designs 545 Primary Source Enhancer 1-channel 500 Series Background Noise Reduction System

The 545 Primary Source Enhancer is the ultimate feedback reduction solution for any audio setup. It effectively reduces feedback without affecting the sonic quality of the source. The 545 senses when someone is speaking or singing into the microphone and allows the signal to pass through. Once the the input falls below the threshold, the unit reduces the gain to eliminate feedback. Unlike standard gates, the 545 does not rely on filtering or digital processing. Its all-analog circuitry provides superb control and sonic performance without compromising the integrity of the source material. At the core of the 545 are Rupert Neve Designs' custom input and output transformers. These transformers combined with the device's intuitive controls, provide superb control and sonic performance. The minimal control set allows for easy adjustments on the fly, even during live performances. Its ease of use makes it ideal for anyone, even in circumstances where a full-time or experienced engineer is not readily available. If you're looking for a reliable and effective feedback reduction solution, look no further than the 545.
