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.

Good, inexpensive work watch
Color: all black watch
Bought as a working watch so I don’t wreck my good watches. It’s been working just fine and holding up well while not taking very good care of it. Keeps accurate time. Glass has stayed clear. Black finish looks good and is holding up well. Seems to hold up with steady pounding. Stop watch buttons are a bit crude and will mess up your time when your hand gets pushed back against it during hard labor. However, I have not babied this watch at all.
