2-channel Background Noise Reduction System for Feedback Reduction and Live Sound Enhancement.
เครื่องปรับแต่งเสียง Rupert Neve Designs Portico 5045 On-Stage Stereo Feedback Reducer, Easy-to-Set up Controls, Threshold, Depth & Time Constant Knobs, Allows for Louder Mics in Concert
The Rupert Neve Designs 5045 Primary Source Enhancer 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.
The device sports easy-to-use controls. A Threshold control dictates the level at which the processor starts working, while the Depth parameter sets how much attenuation is applied below the threshold.
The Time Constant knob gives you access to six different attack and release speeds—twelve, actually, when you consider that the RMS/Peak switch changes the behavior of this parameter. With these minimal controls, you can easily set the processor to suppress anything below the signal’s optimal range.
The 5045 takes line-level from mic preamp outputs or insert sends of consoles and delivers a line-level signal that can easily feed a console or PA. Because of transformer coupling on the I/O path, the unit can interface with a wide variety of gear. It offers XLR connections on the input and output paths.
Features:
- An ideal way to remove unwanted background noise from your audio
- Provides 2 channels of clean signal for greater gain without risking feedback
- Functions similarly to a noise gate but operates on a more discerning principle
- Automatically detects when direct sound is present for perfect reaction time
- Straightforward controls are extremely easy to use for ultra-fast results
