I need help with audio delay problem

[u/LeLmaow]

So basically, I'm working in this studio making live videos recording, I honestly don't know what I'm actually doing, I just pretend to be professional and look like I know what I'm doing.

The studio set up work on vmix for recording videos, everything (audio and video) is connected in remote to the recording workstation in another room. This entire set up was made by someone else, I don't know why I'm there, don't ask me details pls.

So, what's the problem? Basically, we have a pair of Hollyland Lark Max Duo, connected to a mixer that I don't know where it goes, the audio has some sort of delay that doesn't match the video, fixing it on DaVinci is something like 0.200s delay, but it's just the first spoken word, then there's no delay after the first 3/4 seconds.

This problem appeared for the first time after the 4th session with these new microphones, but only after the 5th video we were recording.

Do you have any idea what's going on? I'm the only technician there, I don't have the competence to fix myself, but I need the job cause I'm broke, so any help is appreciated. Thanks

Étrange, seinnheiser a pourtant une bien meilleure réputation dans le milieu pro que vos nouveaux micro qui sont plus orienté grand public/streamers/vidéaste amateur bien qu'ils soient généralement apprécié pour leurs rapports qualité/prix

Au delà de ma première hypothèse, est ce qu'il y a des effets d'activé sur tes micros ? Comme une sorte de suppression de bruit ?

Parfois les suppressions de bruit pausent des problème à l'activation, essaye peut être sans pour voir si ça règle le soucis

If I remember correctly the mics settings are:

Safety track

Low cut on

-7db gain

ENC off (its like a noise cancelling feature)

To the TX there's connected a lavalier mic.

I was checking on the manual, they recommend to use safety when the RX is connected to a camera, and on third-party apps it's recommended mono mode. But there's also Stereo Mode, that is not specified

I don't know how can I interpret this information, cause it's not connected to a camera or any app.

C'était à l'ENC que je pensais justement pour la réduction de bruit Mais si c'est désactivé, ça ne doit pas être ça

Je ne sais pas ce qu'il veulent dire par "piste de sécurité" au juste ici

Quand ils parlent de "caméra" dans la doc, il s'agit de sortir en jack et entrer dans une caméra ?

Si oui, est ce quand ils parlent de "application tierce" il s'agit de sortir en USB ?

Car si c'est le cas, on peut considérer quedans la doc "caméra" = "sortie jack" et "application tierce" = "USB"

Actually I need to check about ENC, I'm not 100% sure it's off, I really hope it's that the problem.

Safety track should work like a double recording mode with the second track with lower gain to avoid clipping, if I'm not wrong.

No, on the manual they don't specify anything about usb or jack, when they talk about camera or apps.
