Hi Richard,
X-8x-x Mit is not compatible with DASH... DASH is PCM based and Prodig is different.
To make things more complex:
X-80 comp with the X-86-C not X-86 X-86 comp with the X-86-C, NOT X-80 X-86-C comp with X-80 (PB only), X-86, NOT HS X-86-HS comp with X-86, X-86-C, NOT X-80, and had a unique HS setting.
In transferring this format there are a couple of PD to PCM DtoD converters, but since these machines were used in the analog domain as mastering machines, we have to keep in mind that the sound of he converters are part of the sound that engineers heard and used. I would capture in the analog domain with these machines.
Hope this helps,
