ETS DNR-1 High Performance DSP Based Noise Reduction Module

ETS DNR-1 High Performance DSP Based Noise Reduction Module

The DNR-1 is a single channel digital background noise reduction processor. It is designed to connect directly to any SM1 series microphone (or any line level input signal) and a DRV, I/P camera, etc. Note- the audio output of the DNR-1 is “line level″ (0db).

DNR-1 location and power The DNR-1 interface box is designed to be located next to a DVR or I/P camera. The DNR-1 (unless connected to an ETS interface box or base station) requires a 120VAC power source within 3 feet of its location. If this is not possible in your application, you can splice in up to 100 feet of 18 awg, 2 conductor cable to extend the distance between the AC power source and the DNR-1.

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 directly compatible with ETS microphones, base stations, other "line level" audio sources and connects directly to DVRs, I/P cameras, etc.
