| Subject: | Excessive noise on analog inputs to XDP-210EQ... |
--> XDP4000X-List message posted by: "Roland M" <mdx400@hotmail.com>
I'm getting what seems to be excessive white noise on the analog inputs of
my XDP-210EQ :(
I'm wondering if anyone else has had such a problem? It seems strange but I
haven't had this noise before. The digital inputs (from a CDX-828 changer
and an MDX-400) are fine, there is no noise at all.
I'm not talking about the "volume over 75% standard 210EQ noise" thing
either. Just at low volumes, either using the HU (CDX-7850) or my analog
changer (CDX-T60) I'm getting a rather annoying amount of hiss at low
volumes.
I never used to get this noise before, however I remember getting some
amount of hiss on the analog inputs only (and I know this is going to sound
strange) when it was very cold outside. Now it is just all the time. There
have been two "changes" in my system since the summertime which may have
caused this but I'm not sure:
First of all I have moved the analog RCAs (Lightning Audio Storm TPX-500 for
the HU and TPX-400 for the analog changer, pretty much the same RCAs except
the plugs are different; twisted pair, both top-of-the-line LA/RF before the
TPX-1000). The move hasn't been anything big, just that I applied sound
damping material (Raamat) to the entire floor and so the cables I moved to
be more neat underneath the carpet since I had everything removed.
Second of all the tweeters (Focal TN45s from a Focal 165V Polyglass comp.
set) were previously behind factory tweeter door sail panels (behind the
factory tweeter grilles) and in the summer I drilled holes out in the sail
panels so the tweeters are mounted so they are directly facing out (with
their own grilles for protection) now.
I thought maybe the slight movement of the RCAs might have caused it but
then there are two sets, would it have happened on both? And perhaps since
the tweeters are now entirely unobstructed perhaps I wasn't hearing it
before? But it is really noticeable now whereas before I never noticed at
all (except in very cold weather as I mentioned).
I am going to try to troubleshoot with some temporarily connected RCAs but
other than that I can't really think of anything other than maybe there is
something wrong with my 210EQ or that it was always like that?
Any other suggestions are appreciated!
Thanks,
Roland M.

Unfortunately I know just about as much about the unit as you do. In fact I
didn't even realise that it could attach an HDD myself! LOL.
You'd probably be better off asking those questions over at the ICIX forum
where people who know more about it (including the guys at eD) would be able
to answer more questions about it.

Yeah Car PCs are cool. The nice thing about them is that you usually end up
with something truly unique in that your Car PC will tend to be unlike any
other one out there (unless you use some pre-fab solutions or outright copy
someone else's existing install); the bad thing about them is the same I
guess in that they usually require a bit of custom work and a lot of time to
think out and put together/install. In the end it should pay off, but be
prepared for a few headaches and a lot of head scratching on the way there!
