Here's the manufacturer's blurb:
The features are what i need (compressor, gate, feedback elminator), and the price is good ($70 to $100 on the Internet). I'm thinking of getting one of these to goose up my flute microphone for live performance, especially with some compression and feedback elimination. And i'm wondering if it's good quality, reliable, etc.Our popular all-round problem-solver combines a ULN mic/line preamp with a variety of useful signal processing options, including our renowned feedback destroyer circuitry, a delay line for speaker time-alignment, an effective yet easy-to-use compressor and a noise gate with LEARN mode. Switchable +48 V phantom power, 24-bit A/D and D/A converters and professional connectivity round out the package and add to the SHARK's ability to adapt to just about any application. Get a five-pack and rack-mount them in just over one space.
Thanks!
