Dm 4800/if fw mkii

[Sachikant Lenka]

my IF FW card runs well on 44.1/48khz.when I work on 96k after some time sound stops,all the lights under fs section blink together with error messege pop ups that all sound stopped.pl contact tascam service.what to do.so i plan to use my Motu 2408 MK3 pci424 via ADAT of built in ADAT port of DM4800.pl help me in routing inside DM 4800 .I am confused about the sync of both the hardwares.

I had this SAME EXACT error using 88.2 - 96kHz with my DM3200. It had to do with the DSP board being defective and prone to overheating. If that is the case... your looking at a $560 part replacement. Just to be clear, you are not clocking to any external hardware right? If you are, don't and see if the message pops up as a test. If you are not externally clocking and using the DM by itself...then it sounds like you have a defective DSP board.

thanx dear for responding.Actually I was in love with the flexibility of this sound card.what to do .you are correcrt.I have to go for a new one.in the meanwhile I have to run the studio.pl go through the following msg and try to help.
MY IF FW has become defective.So now I try to run my studio through alternate motu 2408 mk3 pci 424 till i buiy another IF FW card.Now I am stuck in routing the signals from motu into DM 4800.
My signal will flow
Focusrite MK3 dynamic Preamp-Motu2408-DM 4800
I dont want to loose the benifits of routing fascilities of Dm.
I connected ADAT out from motu to Internal ADAT in DM 4800 and in routing section of DM i have set input ADAT 1-8 to 25 to 32 where in I get 4 separate output to listen and monitor during recording and mixing.
Now the analog outs if mics from studio from Mic Pre is fed to analog ins of motu and again fed from analog out of motu to line in of DM via 1/4"TRS.
Now the problem is
I am not fetting any signal into the chanel section 1-24 of DM i.e. chanel faders,bus assignment and preamps of DM are not getting any signal from mics.
But Cubase gets signal deirecly from mics and record but I loose the control over gain adjustment inside TASCAM .
Can anyone Pl send routing diagrams for such set up so that I will be able to route the signal in the following way
MIC-PREAMP IN-PREAMP OUT-MOTU IN-MOTU OUT-DM 4800 IN-CHANEL 1-24-BUS 1-24-CUBASE 6.
PL HELP
URGENT.

Are you saying that in addition to the "all sound has stopped" error message, your IF/FW isn't working either and if so, what's wrong with it?

Please note:

• The "all sound has stopped" error message IS NOT caused by the IF/FW card. It's usually displayed when there's an issue with the DSP board (defective/overheated).

• A common symptom of a defective DSP board is the DSP chips overheat easily (more so when using the 88.2/96kHz rates). When the chips reach a certain temperature and fail, the DM displays the "all sound has stopped" message. I'm assuming the chips are shutdown to protect them from further damage.

If I'm correct with my diagnosis, using the MOTU interface will not circumvent the problem. The DSP board is expensive ($509 USD + shipping) so another recommendation before replacing is to remove the board, blow out it's connector on the mainboard with compressed air and then re-seat the DPS board. If that doesn't work and you're still get the error message, then you can try mounting an internal fan next to it. If that doesn't work then the only solution is to replace the DSP board.

Again, this is based on my own experience with this error message. I haven't seen the error once since I replaced the DSP board a year and a half ago and I used to see it once every other session religiously.

thanx dear.
I did not understand which DSP u r telling about.Is some board inside the mixer?what is the name of the board in particular so that I can contact TASCAM for a diagonistic tool.Actually I have already reset the mixer under diagonistic mode,cheked everything and everything is fine.can upload the screen shots.
why I decide to change the sound card to Motu is also surprising.Pl read the following .It was a peculiar issue.
As we r recording a lot of indian instruments like Dholak Tabla etc, the players in the floor complained about latency even at a buffer size of 128 and failed to play in sync with metronome.when i recorded the same palyers with all the same set up(room,mics,everything) from motu 2408 mk3 Pci 424 (of course lost the control to monitor the input bus etc from the hardware) the players were happy,plyaed with sync and most surprisingly I recorded more round/tight sound (while in DM 4800 it was sounding hollow i.e.something like room sound)
So i decided to connect motu to dm 4800 via adat of Dm (internal).recording good sound with 4 different listening outs but issue is the mic signal is not coming to ch 1-24 to control the faders and directly go to DAW for which I cant use the compressor of DM on chanel 1-24 while recording.
Dear ultimately I shall have to replace the DSP as u suggest or replace the firewire card but its a costly affair in India.So i have to run my studio with the motu-Dm setup now.pl soneone help in setting Motu-Dm (internal)routing so that I can record smoothly.

uploading screenshots of internal routing in DM4800 connected and using motu2408mk3pci424 as sound card


pl advise if i am doing something wrong

 

[Sachikant Lenka]

this is motu setup

Yes. The DSP board a separate PCB board like I explained a few times above.

Please note that the DM Diagnostic Tool will NOT detect a DSP board issue.
There are no latency issues if you are monitoring through the DM mixer and I am still struggling with why you are saying you need to replace the IF/FW card when it sounds like your sound degradation experience with it might be user error.

In any event, here is the part number for the DSP Board.

Part Number: DDMP2 SV Pack V00167600A.
Retail cost is $509.86 plus shipping.

dear
I am not that trained sound engineer.U r right it may be the issue of DDMP 2 board.But I am unable to understand where I make the mistake for which I record degraded sound.My set up is very simple
MIc-Mic pre-Line in of DM-Cubase.
I special thing that on my Mac Pro ,Cubase under Device Setup where I select the sound card the facility of Direct Monitoring is disabled by default.So while recording manually I have to bring down buffer size to 128 and again increase the buffer size while mixing.
I cant blame the cables,mics,etc as every thing works fine and my instrument players are much more comfortable while I record through other sound card like Motu 2408 or 828 hybrid.
So where i am doing the mistake in DM for which such problem arise.pl advice
