I'm not going to be telling you anything you don't know, but there are always potential noise issues with any digital product. A combination of low output guitars in front, high gain amps afterwards, and incorrect gain settings makes this sometimes unavoidable. The TimeLine will face the same issues.
All H9's current go through audio analysis testing, and must have a signal to noise ratio in the 90-100dB range to pass. So, we believe (apart from rare hardware problems) that these products have an entirely good noise performance, and reported problems are usually as described above.The H9 also has better noise performance than the TF, MF and PF.
It is our belief, that, when set up properly, the H9 has no significant noise issues, as shown by the large number of users who have no problems.
