Get multiple audio sources in sync with your video, using the AD-300 Pro Audio Delay Box from Datavideo. This multifunction sound box offers 5 x input channels: a pair of RCAs, a pair of XLR-1/4" combo inputs, and an additional XLR-1/4" input on the front panel. The combo inputs feature mic- and line-level switches along with phantom power switches to provide +48V phantom power for condenser microphones. The unit offers a built-in mixer to route the incoming signals to a pair of stereo outputs with both balanced XLR and RCA connections to choose from. The 3.5mm front-panel headphone jack provides quick monitoring.

Each channel on the AD-300 offers a digital delay adjustable from 0 to 3000 ms, allowing you to get professional synchronization from multiple sources. In addition, each channel offers a compressor, limiter, expander, and gate, allowing you to tame audio levels and reduce noise for more professional-sounding results. High-pass and low-pass filters along with an 8-band EQ on every input provide precise control over frequency content, giving you additional audio-sculpting power.
