My mod doesn't touch the DSP part, only the output signals from the DACs (and the analog input to the ADC for level control on anlog input A & B). If you had the problem before, it will not magically disappear. On the other hand, if you don't have it, it will not appear with the mod.

Trying to put together this outputboard for DCX,after soldering C1 I started to wonder why only a cap for one Ic when theres holes exactly
the same at the other 5 Ic´s.Is this correct with only one (C1)?:
And whats the 5 opams for?The first 3 I know must be for the input,are the 2 others for analog output?
Would be nice with a schema for this one..
Wery thin pcb tracks..

An externally hosted image should be here but it was not working when we last tested it.

hi guys!
unfortunatly i have no time to re-read all of this crazy thread !!! so i'd like a quick point out if possible
Has anyone succeeded in getting digital outputs from this nice piece of hardware?
simple ? worth it ?
any how-to ?
i'd be seriously glad to be able to use a few of those
as my digi-Xovers for my next HT setup ,
and still be able to use higher quality dacs!
( if worth it .. )

Hi JinMTVT,
With a modified DCX, there's no need for external DAC's - IMHO the AKM is more than adequate, unless you plan to use a NOS DAC, which is a different approach.
The digital out mod consists of bypassing all the DAC's and output circuits, and installing Digital transmitters to each DAC inputs - lots of SMD soldering.

ok thanks for the info
i am not afraid of soldering, but it has to be worth it...
i am currently running a RAKK DAC + some custom stuff and passive output trannies
i have yet to come across a dac that gives the same transparence ...
thing is that, i will need alot of channels ...
and i do not even know yet how i could split all the signals ... will need to run 3-4 DCX for my HT setup
1 for subs and rear
1 for sides
1 for front ... maybe 3 would cut it ...
( 1 additional if i decide on 2 rears... )
all main loudspeakers will be 2 ways
Is there any easy mods to the DAC section of the DCX that will augment its DA quality ?
power supply section ? ( easy and comon sens mods ..)
i think i'll buy 1 right away to test it and compare VS my RAKK DAC setup , and it'll let me familiarize myself with the unit for further tweaking!
If i understood correctly, by using a DCX to set crossovers and delays, splitting the signals for multi-amping ...there will be no problems associated with phase and regular mecanic Xovers ??

These guys sell kits to upgrade the output stage.

They also offer a power supply upgrade solution and a reclocking option. Much simpler than working it all out yourself.
The six channel volume control is pretty cool too. Job done.

wich mod gives the greatest change in output quality?
this comes in kinda pricy if you do them all and have 3-4 DCX to do it on!!!
Hi,
If you want to keep the analog output, with HT, you may want to have a remote control option that also lets you adjust relative levels of the low, mid, hi channels. After all, you power amps on those channels and the various speaker drivers probably have different sensitivities and efficiencies. You don't want to use the DCX digital level control as that cuts into your resolution.
That was the exact problem I had to solve and for which I developed my remote controlled active output mod kit. It is described here:
http://www.linearaudio.nl/6chan-1.htm
There are some user experiences with this mod kit on the DCX2496 yahoo user group:
http://tech.groups.yahoo.com/group/DCX2496/messages?o=1 , pretty positive.

Maybe it is not cheap, but it is necessary. I do not know any other solution that will be less than Jan's kit with all the features. Without modification, you are better off running passive set up, that will most likely sound better than stock unit. Not to mention volume control for 6 balanced channels.
