few problems with video signal and audio

Hi there,
i have a 3 problems.

1.- my english... sorry for that

2.- i have a ATEM TV STUDIO with 2 HDMI to SDI CONVERT...i used two Panasonic HDC-HS80 Camcorder... i connect in HDMI to ATEM TV STUDIO.. but the signal is leaving every 5 second (with SDI CABLE is every 2 seconds) with both cams, sometimes just in one camera...and if i lucky the signal dont leave...

3.- for Audio i using Sennheiser ew 112-p G3 Camera Mount Wireless Microphone System with Canare BCJ-XJ-TRB 110 Ohm to 75 Ohm Digital Audio Impedance Transformer, i connect this in AES/EBU and dont work..

any solution?
Thank you

1.) My english is also bad. No problem here....

2.) ATEM don't like hot environments. Maybe try to cool the ATEM using a fan....
OR
ATEM don't like long HDMI cables. How long is yout connection a) to ATEM AND b) to HDMI-SDI converter ? Try a shorter one...

3.) As I know, is Sennheiser XLR output an analog one. ATEM needs a digital one. Your Canare is an impedace transformer, but no analog to digital converter.... So you need an additional analog to digital converter.
