Rupert Neve Designs 5045 Primary Source Enhancer

Keep on-stage feedback out of your audio with the Rupert Neve Designs 5045 Primary Source Enhancer. This is a two-channel device that tames acoustic feedback in a manner similar too, but not exactly like, a gate. As such, you can use it to help boost the level of microphones in a live performance setting before feedback occurs, all without adding obvious tonal coloration.
