We just recently switched our wireless microphones to the new freq window and discovered RF interference that we have traced to our BM miniconverter Analog to SDI2 box. Our microphones broadcast in the 470-506 MHz range and pick up RF interference on all frequencies. The interference is enough to cause the mics to cut out intermittently which is obviously not acceptable. We record video with a Sony HVR-Z1U Camera to be processed live. Audio is processed through a Berringer X32 Board. Audio and video are combined in the BM miniconverter Analog to SDI2 box. Signal is outputted to post processing through 2 SDI cables (for redundancy).
RF Interference exists when video input is RGB composite or S-Video.
RF Interference is reduced but not enough for the mics to function properly when using only 1 SDI output (which we can do, the second SDI output is for redundancy only).
NO RF Interference exists when Camera is on but video cables are not connected to BM box.
NO RF Interference exists when Audio Only is processed through BM box.
NO RF Interference exists when Camera is on, Audio is on, Video cables R & B are connected but Green is off. However, there is also no live picture when G cable is disconnected.
RF Interference exists using multiple different cables from Camera to BM box.
Camera on or off makes no difference.
Audio on or off makes no difference.
Once the BM box detects signal on the G video input, the RF interference exists.
We are talking to Shure to see if there is anything we can do with the microphone transmitters or receivers. Does anyone have any ideas for us on the video side of things? Thanks.
