First of all, this is a user forum, not the BM Supoort site. Next, audio,delay as measured on the Ursa Mini/Pro is about 3 frames. This is caused by the fact that you are monitoring the audio signal after it has been processed and merged/sync'd to the video (think gap difference between record and playback heads on a audio tape deck, same issue, slight delay on the recorded signal vice the imputed signal.
The only way to monitor audio without delay, is to monitor the audio pre-processing, which is a switchable option on most ENG cameras. However on the Ursa Mini and Pro, you only get processed audio monitoring, which is what a sound recordist wants to hear, that is why the Audio guys wear big earphones to block out the on set sound to hear only what is coming from the headphones as it is recorded, to make sure it gets recorded distortion free, etc.
As far as camera operators go, you can learn to adapt to the delay with time, and get the hang of listening to the recorded signal, while following the action. Having the Camera Operator monitor audio is not always,the best option, better to have a dedicated sound guy, on a field mixer, sending final audio mix to the camera, and monitoring the return audio from the camera. That is why camera audio break out cables are used between camer and audio person, include two audio XLR cables and a return 1/8th unbalanced line return, all in one expensive cable. From the mixer, the audio tech. can switch between pre and post processed audio on the filed mixer, which can switch between the audio return from the camera (post/recorded audio) and pre-pricessedmaudio sent to the camera to be sure they match.
Generally, BM does not speculate about possible changes and upgrades to its equipment until,it is ready for release.
