Help needed to prove that the Victor is a 20 Bit deck

We like to do some testing in the Netherlands to prove that the Victor ZD-V919 is a 20 bit deck.

The test is fairly simple. More details later.
Who in the Netherlands has a Victor and would be willing to help the DCC Museum?

On a sidenote to this I can confirm that the DCC600 has a little strange digital out. One of the sides (L/R) reports 20bit and the other only 18bit, when monitoring it in wavelab through spdif. I’m not sure any information is transmitted on the two last bits, and I think not, but it’s still a bit wierd. My DCC730 does not do this, and only reports 2x18bit streams as it should.

I would really like to talk to you.


Hi. i can write to you right here if that’s ok. It’s no magic tricks to measure bits from an spdif.

Don’t know if the image works. It’ shows a 24bit 44.1 recording from the spdif of my dcc780. As you can see it reports 18bit on both sides and the green bars show how many is used in the audio itself.
I’m using wavelab 6, and the function “bit meter” from the “analyze” drop-down.


This is what it looks like on my DCC600. Unfortunately my drive belt snapped just now so I only got out a few seconds of audio. But it’s strange bits reported from the spdif. 20 left and 24 right.

Thanks for sharing.
How is the software connected to the 730 and 600?
What hardware are you using for this?


I wrote in pm, but I can write it here too:

You need an audio card without SCMS copyright protection because it will block the DCC audiosignal otherwise.
Mine is an RME but anything with spec above 48khz/16bit will do, as it is considered “pro” and do not have SCMS, or as an option to turn off.

Then I simply connect spdif out from DCC to spdif in on audio card and record a wavefile of 24bit in wavelab from the digital input.

The cheapest pro soundcard I know of without SCMS is Zoom U44. That can do what I did.
