DTIPro 32 on the Blink


My DTIPro 32 is throwing tantrums. I'm getting input locked in, but after about 2 seconds of output I hear a click and lose it. (Mute circuit kicking in?) At that point it's locking up and won't do anything until I power it up again. Anybody know if this is a common problem, and/or have any suggestions? I've tried (unsuccessfully) to contact Duster V. re: repair. Time to move on? Thanks.

Guess I'm spending too much time with my 5 year old ... the DTI is taking "time outs" on its own initiative (that's the fundamental problem)... And a meaningful spanking would certainly inflict more harm on my hand than the unit... However, I have considered chucking it against the wall..... think that would help?
For years I used mine via the (optional) ST input without problem. Last year I acquired a DDS-Pro and hooked it to the DTI Pro 32 via IIS. I powered up the DDS, then powered up the DTi. It locked up. I thought it was defective, but after experimentation I found that the DTI needed to power up before the DDS (this power-up order had never been an issue through the ST input).

I don't understand why this happened. I know it is a tempermental unit, though.

So have you changed input connections on your DTI lately? Does it get secondary lock before hanging? Can you try another power supply?
Thanks for the ideas .... I'll give them a try on Monday and let you know how it goes (that system is in my office....) I've been trying to use it with my Esoteric P-10 transport ... conventional digital cable out - into a DDE 3.0 via I2S ... (with no alternatives re: output on the P-10 ). The cable I've been using is the powered AA digital cable; perhaps that's causing the problem Ki mentioned. I bought the DTIPro 32 a couple of months ago, and have never been able to get it to work properly in that system, so I just put my DTIPro back in (with no problems). I did try it between my Cal Delta and Sigma (with a different digital cable), and had the same problem (thought I didn't try the different output options on the Delta). I've been using a PS2 power supply, but also have a PS3 and PS4 that I can try. Again, thanks for the assistance ....
No luck with change of cables, power supply, or sequence for power up of equipment. It doesn't seem to matter what's connected (or if anything is connected at all - input or output). The unit seems fine for a couple of seconds, then completely locks up (with all the lights on). It is worth the effort for the upgrade from my DTIPro? (I've been thinking about upgrading the DDE 3.0 DAC anyway, perhaps its time to rethink the AA combo. Guess I could use the DTIPro 32 as a doorstop...) Again, thanks for the suggestions.
