The AVN-DIO03 is a Dante AoIP network-to-headphones convertor from the Sonifex DIO range. The unit features a single stereo headphone output, accessible via both 1/4” and 3.5 mm jacks, with a front-panel potentiometer to adjust volume from mute (fully anticlockwise) to +6 dB gain (fully clockwise), useful for boosting low Dante stream levels. A built-in limiter with adjustable threshold and LED indication protects hearing by preventing over-levels. The limit can be set between approximately -12dBu and +6dBu using a small adjustment tool. When limiting is active, the blue limit LED illuminates, prompting the user to reduce headphone volume.
