SescomA/V Lip-Sync Corrector

I use open back headphones to listen to my TV, while my wife listens with the soundbar because we like to listen at different volumes. The headphones are connected via a DAC (digital to audio converter) to the optical output of the TV. The soundbar is connected via the HDMI eARC output. The two were never in sync, with the optical feed being earlier by 150 ms causing an annoying echo in my headphones. No adjustments on the Samsung smart TV could solve this problem but this amazing little device connected to my headphones did! I usef RCA to 3.5mm splitters to splice this device into my headphones cable. It worked perfectly. The sound quality was good but there was a loss of volume after connecting this, which I corrected with a volume adjustment on my DAC.

Simple and straightforward to use. Plug input into IN and output into OUT, power it on, set your delay and you're golden. Works like a charm. We're using HDMI to SDI transmission and the video lag was killing us on video presentations. Our audio extractor works way faster than the HDMI to SDI to HDMI processing, about 180ms faster from what we found.Completely happy with the lil guy. A little more than I had wanted to spend but it works very well and sounds just like it did before except in sync with the video now. Its the little things...

This device is absolutely awesome. I searched blogs all over regarding audio lip-sync issues when audio is faster than video and found very little solutions other than purchasing a new digital-ready amplifier and feeding optical-audio through TV. I finally searched Amazon and came upon this solution. This device will help those directly connecting their cable box/input source to their analog sound system (via RCA). In my particular case, the sound was off by 100ms. I set it and it was immediately in sync - 5 min set up. The device can easily be tested by turning up the audio on both the TV and the stereo/amp - then adjust until there is no echo (both TV audio and amp in sync). Audio quality is excellent - no different with the device. Note: This is a powered device, so you need a power strip nearby.

The ear/eye picks up on anything out of sync for more than about 30ms. This item does 50ms increments ONLY. I used this for correction delay between an AV receiver's zone1 and zone2 (in same, large room). If your sources (zones) are not almost perfectly in sync, like less than 5 ms, you could get a flanging sort of effect. I tried this item at it's 50 and 100ms increments and it was very close, but not precise. For more precise control, try the RTS-200C RadioTVsync. I bought one, although priced at 199, it works perfectly for my application (at 75ms delay) and is as precise as you can get at 1ms increments. Retuned this one, otherwise I liked it (especially the small size). In this case, more money does buy more with the RTS-200C.

We have a digital mixer at our church and use "NDI" to send video to our TVs, so between the two, there is expected delay between the audio and video. We play videos from our computer and the sound is way faster (in nature) than the video. We run our computer's audio into this and then out of this box into our sound mixer. We set the delay (200ms for us) and it is so much better with this, no more awkward words before lips move.

Why the delay issues? The extenders process the digital signal then it goes through the network and the monitors have to process this signal again. In most cases the audio is not going through this process and ends up ahead of all the digital processing. This product fixes the problem PERFECTLY! I cannot say how happy I am with the results. We have a large auditorium with 6 - 60 inch display monitors. We used a digital HDMI balun signal boosters to transmit the video. The audio goes directly into the mixing board. The Audio and Video where never really synced up correctly by doing this. Adding the product we put on a video presentation and just kept increasing the delay until it was synced up perfectly. Total amount of time for the fix was 10 minutes. Very easy to use and works great!

I've got 2 separate sound systems on my tv. One stereo using AV inputs and the sound bar using HDMI ARC. It got unsyncd and could never sync them together again. Was a lil skeptical about the price but once I got it and it fixed my problem, made me so much happier about purchasing it.

I have looked for several years for a product that would sync FM transmitters with complex video systems.Finally I found this which works perfectly and easily.
