Hi Anders and all,
I decided to contact Rane about my problem with their Note 110. I copy the =
relevant part of the reply I received below.
Regarding RaneNote 110, realize that this connectivity is a last ditch meas=
ure for interfacing unbalanced to balanced when transformers are not an opt=
ion. For microphone interconnections, the methods listed seldom apply.
First and foremost is the issue of sending phantom power to microphone: all=
three wires must be in place for this scheme to energize the mic.
Second, lifting shields on microphone cables typically adds hum and noise, =
instead of reducing the symptom.
Lastly, when stereo plugs are utilized, these equate two unbalanced connect=
ions on a single plug, therefor correct interpretation becomes necessary.

ppeared to me to be correct for, I'm guessing, not only this Y cable, but a=
ny cable from mic to recorder. I can only think that in my present mental s=

when I did the wiring, I didn't cut off the ground sheath but insulated it =

HD-P2 there was no signal at all! I quickly realised that the missing reco=

orked perfectly. I hope somebody will show me where I went wrong with the R=

ith this AT-8022. I did very rough and ready tests using the battery with m=
y LS-10, and then phantom power with my HD-P2, in the same room concurrentl=
y. On normalising both recordings to a similar level, and then changing to =
spectogram view, it looked pretty clear that the HD-P2 recording was much c=
leaner; the background black indicated this. Although the HD-P2 has slightl=
y less self noise than the LS-10, I don't think this was the sole reason, p=
erhaps not relevant at all. I suspect that phantom power v battery is the r=
eason. Any comments very welcome, and I'm very aware that my tests were by =
no means scientific! Either way, unless further testing proves otherwise, I=
'll be using this whenever possible, with the HD-P2. It's hardly worth men=
tioning, but the HD-P2 recording also sounded better.
