Topic: Sony PCM-D100

uncleyug,

optical in has no problem with ground loops. Consumer digital interfaces (aka SPDIF) are unbalanced. Some devices have galvanic isolation for SPDIF with pulse transformers on their output, but not all. So you can expect hum problems if you want to use your recorder in conjunction with your PC as an audio interface (H2 is famous for that).

Opto is by default fully isolated.

Coax-to-opto and opto-to-coax adapters are available:

Hope that helps.

Hosa makes a nice DFC (Digital Format Convertor):  ODL-276A I think is 24/96...  And they run on DC power so you can stick one in your bag easy...

I know the D50 doesn't work with all devices for example UA5 so I'm wondering if a converter would work or if the D100 will be compatible with more devices.

Was the D50 tested with a DFC between the UA5 and the D50 (UA5 > SPDIF > Hosa > TOS > D50)

You shouldn't need one since the ua5 has an optical out.  My point is that the D50 might not work with a converter.  The only pre/adc I know that the D50 works with is a V3(optimod) with the upgraded chip or a usbpre2

Yeah, for newer recorders, you need newer adcs that conform to the final spec. Not many cheapo units are going to be designed with that in mind.

Anyplace still selling a TOS > right angle mini TOS cable like I used to use with a JB3?

JVC was the last group I knew of making them en masse. Maybe a boutique shop might do one though.

Yeah, I know the D50 had issues with some units.  I don't know enough about how SPDIF works to know if running a converter and using the SPDIF out of the UA5 would correct that problem??? 

I'm guessing it doesn't and that you're going to have a newer Pre/ADC in order to use the D100...

Very few SPDIF converters change any frame data, so the Format converter will do nothing to make the signal work or not

[F.O.Bean]

Def pretty I have no use for the opti in but for others that's a huge game changer. For now, ill stick with my m10. If dsd was more compatible tho, I'd snatch one or two up no problem

[jbell]

That's what I'm thinking!

If the AD is on par with the Korg MR-1 - I would never use an external AD with this deck and record DSD - there is no way a UA-5 or even a Mytek would offer any better sound IMO.  The only need for the optical in would be for xfers, etc

[yug du nord]

With the digi out, I'm guessing that this could sync up with an external ADC to run four-channels...  pretty cool for such a small deck!

Good point I wonder if you can clock sync via the SPDIF's (ala the Korg MR-2000) - That would be nice if you can run more then 2 channels DSD or even PCM

Pretty much, yeah I agree. This is basically a D50 that does DSD and has a better volume lock on it. If you wanted to use an external ADC (which is likely to be PCM) then you're almost better off getting a cheaper D50.

Wish they could come out with a DSD firmware for the hs-p82 then the discussion would be over 
Tascam already has a few DSD playback and bench recorders
