Thanks for the input Graham, before I normalise the meter shows barely 48 but after between 12 and 24 and louder. Right clicking the meter shows it set at 0 – 60. Also the puzzling thing is when clips from a HDV camera are on the same timeline the HDV cam clips sound waves are normal whereas the EX clips remain flat. Even after normalising the EX clip and opening it in Sound Forge the sound waves are not visible (but the sound is). After ensuring that “Import MXF as Multichannel” was checked I have four sound channels instead of two (I normally import stereo as two mono channels. I have tried recording with the level wheels on the EX to near max but the sound waves are still not visible. My brain hurts!!
