Hello lopelo.
MXF XDCAM HD with 6 audio channels is not a standard broadcast configuration, so I guess you're going to use a custom FFMPEG command for that.
Supposing your original media already contains those 6 audio channels, I would try with something like this:

ffmpeg -i "input_file_path" -vcodec mpeg2video -b:v 50M -g 15 -bf 3 -minrate 50M -maxrate 50M -bufsize 100M -r 29.97 -flags ilme -top 1 -pix_fmt yuv422p -s 1920x1080 -aspect 16:9 -acodec pcm_s24le -ar 48000 "output_file_path"

Sorry, it's not necesary to use a custom ffmpeg. You can select XDCAM encoding and select same as source in the audio layout. It should output a MXF with 6 audio channels if you used that in the channel mixer.
