ETS DNR-4E Four Channel Economy DSP Based Noise Reduction Module / Interface

ETS DNR-4E Four Channel Economy DSP Based Noise Reduction Module / Interface

The DNR-4E 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-4 is also effective in eliminating microphone pre-amplifier noise. The DNR-4 is directly compatible with ETS microphones, base stations, other "line level" audio sources and connects directly to DVRs, I/P cameras, etc.

The DNR-1 is a four 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).

Key features:

• Standard RCA or 3.5mm jacks for connection to DVRs etc.
• Adjustable input and output “line Level″ level controls.
• ETS microphone or RCA line level input.
• ETS base station or RCA line level outputs.
• Euro-style connectors makes cable terminations fast and clean.
• 500-4Khz Frequency response
• Up to -40db noise reduction (depending on type of noise)
• LED power indicator.
• Power: 12VDC @ 100mA
• Reverse polarity protected.
• All power circuitry and cable runs protected with auto-reset type fuse.
• Black plastic ABS housing.
