Thanks oryoki
this is really interesting stuff,

can you tell us the character of the noise?
If I read you correctly it seems the P48 is as Un-clean when no current is=

being draw as it is with the fairly heavy draw of 5.7ma the NT1a takes, is=

this true you reckon?
Be very interested in knowing what the noise is like with a dummy load,
don't know if you intend to do that.
But look forward to any more info as you get it.

 Re: Zoom H4n just arrived


A little more testing of my H4N revealed some quirks.

First, if you try to record using a single mic connected to XLR with phanto=
m
power on, the other channel records a relatively high level of noise.  This=

seems to be caused by the unterminated XLR input.  Plugging in a second mic=
,
but leaving it turned off, reduces this noise.

Second, with phantom power on, the noise level is higher than with it off
and the mics receiving power from an external power source (ART Phantom II=

in this case).

Third, the 1/8-inch (3.5 mm) minijack on the rear of the recorder has less=

self-noise than either XLR input.  Recordings made with a Rode NT1A mic
powered by an ART Phantom II power supply and connected via the minijack ha=
d
very low levels of self-noise.

Fourth, the right XLR of my H4N has a higher self noise level than the left=

XLR input.  The difference is quite noticeable.

These listening tests were performed in a very quiet setting, and with the=

goal of finding the recorder's self-noise level.  If you record in a settin=
g
with a higher level of ambient sound, the H4N recorder's input noise is
likely to be masked.
