Datavideo - AD-300

Datavideo AD-300 is a professional delay unit capable of satisfying, on its own, the multiple audio processing needs encountered in A/V post-production. With 5 input and 2 output channels, it acts as an audio delay to synchronize an audio signal with video, mixer/matrix router, equalizer and signal processor with various filtering effects on input sources, including pass filters. low and high pass. Audio delay is adjustable up to 3000 ms for each input channel independently to achieve precision synchronization between audio and video. The equalizer is divided into eight frequency ranges from 125 Hz to 16 kHz, each with ±10 dB boost to create desired effects and adjust the timbre of both vocals and music.
On the 2" LCD screen for menu and parameter selection, you can use the full range of audio processing functions (Effects), including the compressor / limiter up to a compression ratio of 100:1. The expander / gate allows for more distinct volume changes for both instrumental music and vocals and again the maximum selectable ratio is 100:1.
The AD-300 has built-in balanced or unbalanced audio conversion to ensure the output matches the desired format, and also features a toggle button for switching between MIC input (even with +48 V Phantom power) and line input, on three inputs.
