    Audio

    What am I missing? I am trying to send audio into the PTZ camera and the sound is WAY HOT that it just clips but at the same time the volume is so low you can hardly hear it. I have tried the Line and Mic settings with no luck. I really need this to work.


    Thanks

    So where does the audio come from, what device? I've connected a powered lavalier mic to PTZ1 and got perfect sound over NDI, have not tried a LINE source though.

    I did help one guy that had audio issues, turned out that his XLR-to-Mini adapter plus was also an attenuator and that was causing issues.

    Besides adjusting audio in TriCaster, I believe you can also adjust via the browser interface for camera itself, check that

    Thanks

    Thanks I will give it another try. My plan is to use several Microphones in a board meeting setting and bring the audio back to the studio over the PTZ camera using NDI. I would be using a small mixer on site to adjust the sound before sending it to the camera. The board room is across town but on the same network as my studio.

    Hi,
    What is your connection between the mixer and the cam ? It seems that you might have a phase trouble, how is your cable made ? Which output are you using from the mixer ?

    It is a Peavy PV10 mixed I have used a 1/4 inch reduced down to the 1/8 inch into the camera. I have tried all outputs on the mixed with the same results. I can hook a single Mic into the cam and it sounds great

    The 1/4" to mini-jack adapter, is that mono on both ends? If so, and camera is definitely set to LINE level input, then I don't know. Don't use stereo plugs.

    I worked with one guy who converted XLR to mini and the converter was actually an attenuator so something else to watch for. Keep a clean signal path

    Thanks
