The DNR-1 is a DSP (Digital Signal Processor) based background noise reduction unit. It is designed to digitally screen out voice from other back ground sounds picked up by microphones. The DNR-1 is also effective in eliminating microphone pre-amplifier noise. The DNR-1is compatible with ETS microphones, base stations, other "line level" audio sources and connects directly to DVRs, IP cameras, etc.
