the audio levels need to be setup on the Tascam at -12dB, or around that value. If you didn't check the levels at the time of recording, it might the case that the value was lower than -12 and that is why in your computer the audio is very low. The reason you might not notice this when listening on the Tascam could be because when you listen back, either with headphones of internal speaker, the volume is not the same as the recording. You could have a good volume on your headphones but you could be recording at a very low or very high level... I assume that could be the case. If you are using another device to record, with the Tascam, you will need to check the audio levels as well, all around -12dB.

We bought them from CVP or Proav, the main suppliers in the UK. In Europe you have Thomann, who are great. We make the kit specially for our students at the University of East London, so some of the items you see in the video are bought separately.
