| Subject: | C90 and 4000X connections |
--> XDP4000X-List message posted by: "William Ko" <kowill@hotmail.com>
Hi everyone, this is my first post as i am new to this forum/ email
list-serv. the question i am having is the: Recently i had my system
installed (C90, 4000X, and CDX-828 Changer), and the installers insisted
that everything go analog (there are no optical/digital connections
anywhere). i asked them why, and they said that i wouldn't be able to
notice a difference (the rest of my gear consists of 1-10" image dynamics
IDQ sub, 3-Diamond audio Hex series in the front, and eclipse 6.5" points
source in the rear all powered by Mmats amps). So right now, i've got
really lousy cables going to and fro. But here's the weird thing- recently
i took out the head unit to check the wiring job, and only the front output
RCA's are connected, yet i get sound from all 4 of the speaker channels (the
bus cable is also connected). What gives? And how should everything be
properly wired up using optical connections?? Help!
William

Hi, and welcome to the list!
First of all the installers were incorrect in saying that it didn't matter
whether you used digital or analog connections. That is completely false.
What happens if you use analog connections is multiple processing which is
not good for sound quality really. What happens with analog connections is
that first the (CD) sources like the changer and HU will do the D/A
conversion once. Then when the analog info gets to the XDP-4000X, it uses
its own A/D converter to convert it back to digital and then performs
crossover, eq, and processing in the digital domain. Then it goes through
the D/As in the 4000X before it gets to your amp.
You should see why this is unfavourable. The XDP-4k does all of its sound
processing in the digital domain so to use analog (where you could easily
use toslink connectoions) is a waste of even having the XDP-4000X to begin
with, IMO. The only analog connections you should have are from the XDP-4k
to the amps, but you also have to have an analog run from the C90 to the
XDP-4k because that will take care of the tuner (which has to stay in analog
before it gets to the XDP). The rest should be handled by toslink. Both the
CDX=828 and the C90 have digital ouput capability and should be connected
that way if possible--and it is possible! (You'll need an XA-D210/211 for
the C90 though).
As for the wiring of the analog connections, the installers are actually
right about that. Whether you are installing with analog or digital
connections there will always be one pair (and one pair only) of RCAs used
if you have a DSP processor like the XDP-4000X. (If you are going digital
you still need that RCA cable for the tuner as I mentioned previously). The
XDP processor needs only a left and right signal. The rest of the
processing is handled by it, not the HU (everything from fader, balance, eq,
xover--everything is handled by the XDP when it is installed).
Also if things were done via analog, you'd also have a set of RCAs going
from the changer to the XDP. (And then, of course the RCAs from the XDP to
the amps.)
Also in all connections you'd have UniLink cables going to each unit.
They way you have it hooked up is likely correct, for hooking it up the
analog way. However, I would seriously look into getting the XA-D210/D211
adapter for the C90 (if you don't already have it) and a few toslink
(optical) cables and fix up the install. Really, you're wasting such an
amazing unit as the XDP-4k by hooking it up via analog when you don't have
to.
If you want to hook it up via optical you'll need the mentioned adapter for
the C90 and two optical cables (one for the C90 to XDP and the other for the
828 to XDP). You'll need to keep the RCA going from the C90 to the XDP but
remove the RCA from the changer to the XDP. That's all you really need and
you'll be all setup properly.
Keep us updated and don't hesitate to ask for any assitance.

Hey William and welcome the listings!
Roland is correct of his statements to you. I feel that the installer wanted you
to take the car, and he was way out line to tell you that there was no optical
output. Of course there is a output, because it is clearly mentioned in the
installation manual. Also, the manual states what the list of items that are
optional.
The only thing for you to remember, there is a toggle switch on the underneath
side of the head unit, so you can select between the digital out or analog out.
Good Luck, Tony

I really suggest you switch to the digital outputs on your system. I have a
C90 with an XDP-4000X, and a CDX-848X cd changer. I had this place install
it, Soundwaves in Minnesota. They did a horrible job. Originally when they
installed it, I had a 210EQ setup with the system, instead of the 4000x.
But the ended up breaking off the digital connection of the c90, and to this
date, it still doesn't work. I went ahead and installed the 4000x myself,
but the digital connection from my c90 is dead. I guess what I'm trying to
say is, I still have the digital connection from my 848x changer, and it
sounds so much cleaner, deeper than the c90 at this point. Most wouldn't
notice, but I can definately tell the difference, and if you went to the
trouble of finding and spending so much on your stereo, I'd trust you'd
notice the difference too. Let me know
Bobby

Bobby,
Did you replace the optical adapter XA-D211 piece?
That might be your problem, as I already went thru one. I thought the
deck's optical
output died on me, until the tech diagnosed the XA-D211 adapter as being
faulty!
No joke, try and swap it out...

I don't know what your talking about. I don't see a switch on my
CDX-C90. I looked all around. I think you activate the the digital
output by entering the initial
setup menu.

Yeah, Bobby I was going to ask you something along the same lines... Did
you break the XA-D210/D211 adapter or did you break the connector/optical
out board on the C90? I'm not sure about how the C90s optical out board is,
but on the MDX-400 it is just a little board that plugs into the main board
and then has the connector soldered on that little board (that is where the
XA-D211 plugs in).
If yours is like this (and I suspect it would be similar) then the fix isn't
that expensive. The actual receptacle part is probably going to be about
$13-$20 and the optical out board is about $5. You'll just have to do some
soldering to put the receptacle on the little board (again if it is the same
as the older units). If you don't want to do this, I'm sure a repair
facility could do it for probably less than $50-$60.
Now if you've cracked/broken the connector on the main board that is an
entirely different story. That would be a much more expensive fix. Or if
that was the case you could always tap into the ICs needed on the mainboard
for the digital ouput stream and the voltage to run the optical LED.
Anyhow, I dunno how bad it is but I think you've got a good chance of it
being a (relatively) cheap fix.

I know on the CDX-C910 and also the MDX-400 and probably any other older
head unit that had optical output there is that switch you are talking
about. But I thought on the C90 the switch was not there and you set
digital or analog output mode on the onboard menu system of the C90...
Doesn't the C90 switch from analog to digital this way instead of by the
switch?
