Topic: 722 users....a/d stage opinions?

[MattD]

Yeah but even though your going analog out of the 722 the signal still passes through the digital gain stage of the 722.
I’m pretty sure this is how it work ;-) ..

The analog outs are post DAC and not just routed there from the analog ins?

I'll post a new thread about this with a poll.

Yes sir.

[Brian]

the analog outs on the v3 are post DAC?  that's seems odd.

[scb]

can't be on the v3.  you can turn the adc off and it'll function just as a preamp, so the analog outs must be pre adc

Pretty sure the V3 analog outs are pass-through and do not go through the ADC/DAC.  But I think he was talking about the 722:

I didn't find anything in the 722 manual to indicate this is the case.  But...that doesn't mean you're not correct.  The manual does indicate, however, that line-level analog inputs may be controlled via the same analog knobs as the mic-level signal, but alternatively may be adjusted via the menu.  In the latter case, I believe it's simply digital control of an analog gain stage, i.e. the mechanism for control is digital (the menu) but the gain is applied in the analog domain.  Since I don't own one, though...I'll defer to you early adopters and wait for a more definitive response.

There is no DAC in the V3.

There is no DAC in the V3.

that's what i thought. 

When inputs are selected as the source for the outputs,the state of recording or playback activity has no effect on the output signal. This allows uninterrupted audio at the outputs.

this sort of leads me to believe that this statement:

]Yeah but even though your going analog out of the 722 the signal still passes through the digital gain stage of the 722

is not necessarily accuate, but i'm not positive.  Has it been mentioned on the support board by an SD Engineer?

Justin at SD confirmed this during a phone call.

[Brian]

right on.  thanks!

Very interesting!  So the 722 does NOT offer analog-pass through from the mic/line inputs to the analog outputs?  I'm a bit stunned, frankly.  Given the AD2K and its lack of (I think)  analog passthrough, I'm still not sure there's any better way to run the comp, than as already noted (without the MP2), i.e. I still think it's a better comp to keep the MP2 out of the mix.  Looks like comparing the AD2K v. 722 ADCs just isn't easy, after all!  Though the V3 / 722 comp is much easier given the V3s analog pasthrough.  Thanks for the info, Zee - very interesting indeed.

brian you are correct- there is no analog passthru on the 2k.
I am probably going to run various comps -
not only the mbho>722 vs mbho>722>2k>vxpocket  at 24 bit
and also mbho>mp2>2k>vx

i can run this all at the same time i just need a 2nd computer/vxpocket hehe... my computer only has 1 pcm slot.

anyone gonna be out for sts9 here in socal in a few weeks? i'm thinking i'll do the comps there...

so lemme get this straight....no analog out in the 722, that has not already passed through the dac stage. no spdif out at 16 bits. right?

[Lil Kim Jong-Il]

no spdif out at 16 bits. right?

Not exactly.  The SPDIF outputs whatever bit rate/depth is being captured or from the file.  It's just that the 722 will not produce a resampled/dithered output at the SPDIF port.  If you record at 16-bit, the SPDIF out will be 16-bit.
