The AV Tool AP-411 Lip Sync Corrector is a compact device used to correct audio/video timing mismatches that result in the loss of synchronization of the two components of A/V program content. Since this problem is virtually always caused by the program's video component arriving after the audio component, the AP-411 Lip Sync Corrector provides up to 300 milliseconds of delay for the audio component to restore A/V synchronization to the program material.

Excellent specification of >80dB S/N plus <-70dB of crosstalk and <0.01% Total Harmonic Distortion (THD-N) are coupled with a 48kHz sample rate to provide superior performance under demanding conditions. Inputs up to 2Vrms are accepted and the output level is a maximum of 2Vrms. The unit requires only 5VDC for operation and consumes only 0.5 watt of power. An AC Adapter is provided.

      Comments about AV TOOLBOX AV Tool AP-411 Lip Sync Corrector:

      Used three of these units to equally delay a 5.1 signal to match the delay of our plasma monitor. Using in a professional color correction suite. The only draw backs are that this device has "stepped" fixed values of delay. It is not variable. Unless your picture delay is the same as one of the fixed values (mine was not) you have to compromise and find the value closest. Ours ended up about a 1/4 frame late. Late is better than early when adjusting sound to picture. Still within the margin of offset that most people can perceive.
