Xiegu GNR 1 Digital Audio Noise Filter

Xiegu GNR1 digital audio noise filter is an audio processing device integrating digital noise reduction and digital filtering. It will effectively reduce the background noise, improve the signal-to-noise ratio, and make voice more clear and intelligible. GNR 1 works with HF and VHF/UHF transceivers, receivers and other radio devices suffering from low signal-to-noise ratio.

Xiegu GNR1 supports an external passive speaker and provides 3 Watt audio output power. Independent adjustment of input and output audio levels, selection of high or low input impedance, support two audio outputs (3.5mm stereo output, RCA output), headphone output and automatic switch of headphone or speaker output.
