69.132.141.143
I am trying to insert the DEQ between my Lambda II transport and MSB Gold Link III. I have configured the DEQ for AES/EBU output
The meter on the DEQ indicates that it it recieving and processing the input
My DAC "lock" indicator flashes when I turn on the DEQ but doesn't lock onAny thoughts and suggestions you may have are most appreciated!
Here are a couple pics of the DEQ's IO menu configuration. I'm hoping that the problem may be a setting that I'm overlooking
Here's the input page
and the output page
Thanks for looking!!

Follow Ups:
Normally when the DEQ is getting a 44.1Khz signal from a transport it will show 44.1Khz in the window that now says unclocked. Have you tried to generate pink noise from the unit? If not then try this. Select pink noise and accept. Then the sample rate window will default to 96kHz. If your DAC accepts this then adjust the level of the noise gain until you hear something. If not then adjust the sample rate of the pink noise to 48 or 44.1 Khz. If you have sound now then you know the digital output is working ok.You say when you send signal from your transport to the DEQ that the green level meters are reporting signal? Does the sample rate window stay unclocked when this happens (I remember you said the screen shot was with nothing hooked up so unclocked makes sense in that case)? If it reads a value, what is that value (32, 44.1, 48, 96)?
Are you sure that you are not plugged into the microphone/RTA input instead of the digital input?
The screen shots I posted are static. That is, nothing is hooked up to the DEQI'll have to reinsert it into the system and see if the display changes
Sorry If I misled anyone

Does the DEQ play from it's analog outs? The display on I/O pg 1 should have the number of the incomming sample rate (such as 44.1) displayed and yours shows "unlocked" which is not correct. It looks like your problem is an issue between the transport and the DEQ not working for some reason.
"Does the DEQ play from it's analog outs?"I don't have the proper cables/adapters to find out
"The display on I/O pg 1 should have the number of the incomming sample rate (such as 44.1) displayed and yours shows "unlocked" which is not correct."
When I choose the DIG XLR in the DEQ defaults to the clock setting as XLRIN and the sample rate is unlocked. I don't know how to change these from their default settings. Could you point me in the right direction?
"It looks like your problem is an issue between the transport and the DEQ not working for some reason."
The DEQ's level meter is modulated by the musical signal when a disc is playing. That makes me think the feed is okay. I not sure about anything else :~)
Thanks for your help

The sample rate must display a number to indicate that the DEQ is locked to the incomming digital data. There isn't any additional setting for this. You have a problem. Are you using AES from the transport or RCAs with an adapter? What is the date code? I have another person writing me with the same problem.
I am using the AES/EBU out from my transportThe date code is 0602
You help is most appreciated!!

Try 2..on my part. The transport/deq should be fine. The levels moving should indicate the input is ok. In that case, in all likelihood the analogue outputs ARE working, even though you can't test them (although you could with, again, a couple cheap adaptors xlr to rca). BUT, the earlier poster is right--it shouldn't be saying unlocked...to me that means it's NOT locking on your transport. It is not a setting, it is a reporting of what clock speed the input is. Put it to pink noise and you will see 96. It doesn't make sense to me that it says unlocked AND the meters are moving. I fussed and fussed with mine before I got it all figured out. My situation isn't the same as yours, so it doesn't help much--but the owners manual is very opaque and doesn't tell all. Do you have coax out on your transport? Can you try anything other than aes from your transport?
When it says "unlocked" what I have taken that to mean is not that you can change some setting to get it to lock, but, rather, that there is something amiss with the incoming signal such that it CAN'T lock on it. Also, make sure all the cables are tight.
If you're trying to send a 96 kHz digital signal to your DAC via a single digital cable, you should find out if the digital receiver can take such an input from a single line. And if the transmitter from the DEQ 2496 is sending a 96 kHz signal. Often, many such interfaces handle signals up to only 48 kHz, but various products handle this somewhat differently.Note that many DACs that do take signals at 96 kHz require two digital cables in order to run at full sample rate.
Also note that the Link III itself also upsamples to 96 kHz. You may be trying to separate the upsampler from the DAC, but the transmission between separated upsampler and DAC may be compromised, relative to it being done in the same box, where such linkage should be optimized.
Although I think the real problem is asynchronous upsampling being done in the first place....
"If you're trying to send a 96 kHz digital signal to your DAC via a single digital cable, you should find out if the digital receiver can take such an input from a single line."I thought I was defaulting to the transport's clock in the input screen where the clock is set to XLRin. The sample rate seems to default to "unlocked" in this clock mode. With this cockpit of controls, I'm not really sure what I may have overlooked.
Much thanks

Check your cable wiring. There is some inconsistency in the industry between wiring on pins 2 & 3.
"Check your cable wiring. There is some inconsistency in the industry between wiring on pins 2 & 3."I'm not sure what to check for. I'm using identical 110 ohm cables. The DEQ is obviously locking on to the transport because the musical signal modulates the level meters of the DEQ
Some manufacturers use pin 2 for positive and pin 3 for negative. (Pin 1 is almost always ground.) Other manufacturers use the reverse for pins 2 & 3. It might be interesting to see if your connection improves if you switch pins 2 & 3 at (only) one end of the cables. If you're using commercial manufactured cables, you might want to experiment with a set of homemade cables first. You should be able to find the connectors and cable for $25 or so.
I have a deq but have not tried aes out. Hopefully someone else has. But I believe that all of the outputs are always live. What happens when you select the s/pdif? Does it work then into the appropriate dac input? Once you select one on deq, there is something you have to do to accept it. Like push the large button in, isn't there? Good luck. Im sure someone here will have a definitive solution for you.
"What happens when you select the s/pdif? Does it work then into the appropriate dac input?"My Dac does not have a toslink input so I can't check. The s/pdif is via an RCA
Thanks Tom

You can still test s/pdif I think. I don't have aes on my dac but run coax to it from the deq via an xlr-coax adaptor that I bought for $12 at Guitars Center. I didn't read the later posts above, so maybe the problem is solved, but as a diagnostic, if it isn't, this might shed some light. Good luck!
