The AP-411 Lip Sync Corrector from AV Toolbox is a compact tool that allows you to correct audio/video timing mismatches that create a loss of sync in program content. Typically, a loss of sync is cause by video arriving after audio, so the AP-411 provides up to 300 milliseconds of delay for the audio component to restore audio/video sync.

The device has stereo RCA input and output connectors, which can accept and output up to 2Vrms audio levels. It supports a 48kHz sample rate, and requires only 5VDC of power to operate. An AC adapter is provided.

        Comments about AV Toolbox AP-411 Lip Sync Corrector:

        This is a gadget built for a very specific purpose and seems a little expensive compared to something like an Alesis Nanoverb which can do so much more for less. However, this little box solves a huge issue, and that is matching audio delay to video delay. We use 3 of them to cover all 6 channels in a 5.1 editing suite. Our video goes from the edit station to the 4K monitor via HDMI. The audio goes analog from the sound card to a 5.1 amp. As is typical with all HDTV and UHD monitors, there is a small (150 millisec) delay of the picture in the monitor due to the time it takes to process the signal and display it. As a result, the audio would come out the speakers 150 ms before the picture, thus creating a terrible loss of sync that's really annoying. This little gadget allows delay to be dialed in to the audio in 50 ms increments, up to 300 ms. We set all 3 to 150 ms and problem solved. They have no power switch so we plug all the wall warts into an extension cord plugged into the "switched" outlet on the back of the amp and they come on and off with the power button on the amp. My only complaint is that they are so small and light, what the heck do you do with them? We velcroed them into the back of the rack.

            Did the trick. We use DVI to ethernet converters to get the video from 4 cameras to the video booth. It caused a delay in the video signal. The Lip Sync Corrector allowed us to get everything back in line.

              I use this as a delay for TV and webcast production. It's easy to use and has a clear signal. Wish it had XLR connectors, but not a big deal.
