If it works for your levels, fine. I don't need to convince anyone of anything. Facts are facts and the r09 issue is old news, even if some haven't yet noticed their recordings are distorted or sound worse than they could. Some of us are looking for compact recorders that perform similar to a 7xx in three very important areas - reliability, audio quality, and signal handling.
The problem is the r09, and probably the hr, distort before they clip and do so at fairly comparatively low levels. So whatever edirol mfg spec exists on max signal handling before clipping is wrong. It's actually even lower than advertised.
There are "accepted" recording levels that a/d's should be able to take before clipping or distorting. The world will not recalibrate for the r09/hr.
If you take a patch out of someone setting levels for a piece of pro gear, you risk distortion. I believe even non-pro signal levels will distort the r09.
If you record with a v3 and set levels appropriate to the digital output or built-in a/d, the analog output will be wayyy too hot for the r09. Even at trim setting 1, you must compromise and turn down the pre or the r09 will clip (and regardless, it will be distorting bass).
So the solution is to compromise with input pads... and try to find a portable that has better signal handling.
