I have run in to an odd situation, something I just started noticing a few days ago. What it is is DC on the DI/O output. How I discovered this is playing with...
I have an art di/o that was modified by Kevin Morris. The power supply has a torroidial transformer and it does not hum. I do not know enough about electronics...
Craig, I'd suggest you check out two different areas. First I'd take a hard look at the transport? Perhaps the difficulty lies there and not with the DIO....
... Gary, thanks for your thoughts. I have the transport "isolated" with digtal output and DI/O digital input transformers, as well as a series 0.1uF cap at...
Craig, Very strange that it has minimal sonic impact. Is the offset on both channels and how long does it take to develop to 6V DC and how long to 14V DC ?...
... channels and how long does it take to develop to 6V DC and how long to 14V DC ? From what I know of the circuit diagram, a long time constant DC drift can...
Hi, I am using a 9V 3.4A toroidal transformer with the DI/O sourced from Toroid International and it is working very well. There is no humming and it is way...
... Toroid International and it is working very well. There is no humming and it is way better than the stock supply. ... Do you have the tube installed? My...
Hi, From previous posts, it would appear that an EI transformer would be better than a toroid for a DIO power supply. 1. Is there a reason why many use toroids...
... See the EI ones I mentioned on my web site, they're Hammond 10V @ 4.8A IIRC, 10V is OK, many people make similar ones (see Digi-Key). Also used Plitron and...
Hi, would their be any advantage to using an " R" Core type transformer and does any one know of a source that could provide them. Regards, Karl ... From:...
I was away yesterday celebrating the "Lunar New Year" arrival but left the DI/O on repeat to see if I could induce output offset on the order of the rail...

Hi. After hearing all the hooplah about the ART DI/O for the last couple years, I finally decided to get one. It's been burning in, only thing I've done...
... I have an M-Audio 2496 Audiophile soundcard - I bought the DIO because I didn't realy like the idea of the ADC being in a noisey computer case. I have just...
Yea, I have the M-Audio 24/96 card, and I hate it's sonics - I use the coax I/O and external converters, and get *much* better results. (Use the M-A 24/96...
Hi John, I never did get an answer that I totally understood. I didn't pursue it because I just dialed my attenuator on my preamp down a bit. This woked fine...

Steve, http://home.ca.inter.net/~cfraser/DIOFAQ.htm John, with respect to the A/D. All the "hoopla" you have heard is basically towards the D/A conversion. So...
Hi Tom, The values and construction dtails have alaways been available for the attenuator circuit on the cfraser site. My question has always been as to the...
Those values (output through 3.3k, end of 3.3k through 1.5k to ground) will reduce the nominal 7 Volt output to around 2 Volts. This will get you in the...
