Topic: Tascam DR100 MKII (as Bit Bucket) and Mytek Stereo192 ADC - Incompatable?

[page]

Ok, I can sort-of use the DR100mkii as a Bit Bucket....

The SD702 will lock to the Forssell's AES (96K) signal AND also
output Consumer level SPDIF 96.096k signal to which the DR100mkii will lock with.

So I can use the DR100mkii as a backup, but unfortunately I cannot get rid of the SD702
since it is the only recorder I have that locks to the Forrsell. I bought the DR100mkii thinking
I might not need the SD702, but I am now discovering how great a machine this recorder is.

Theres something screwy going on there... I thought the 7 series boxes didn't resample if they locked onto an incoming signal. I can see them changing from AES to a consumer level voltage on the digital out, but pushing out a different sample rate doesn't seem right.

Well, I set the sample rate on SD702 to 96.096, but it is still locking to the Forssell's signal. Maybe there's resampling of the input signal, which actually is no good because I don't want to change the signal being sent from the Forrsell. Thanks for bringing this to my attention. Peace, Marco

a simple email to sound devices will explain whether it resamples or not (or a post on their forum).

I heard from Sound Devices and the sample rate that will be output is the AES signal the unit locks to, so this means the DR-100mkii is one weird, finicky unit when it comes to the Digital input. It locks to the SD702 by itself at 96.096 but when chained with Forrsell it locks to 96k, but will not lock to the Forssell's SPDIF directly. Anyways, I might just run a firewire disk off the SD702 as backup instead.

I suspect due to header information that is being sent and other aes/spdif format differences.

Has anyone tried the Tascam Dr-100mkii with the SPDIF out from a V3 or a Benchmark AD2k? That is to say, does it lock with no problems?

anybody got the answer to this?

Anyone used a Tascan dr100mkii with a mini-me?

I don't think the dr100 will work with the minime - pretty sure I read this somewhere on tonedeaf's dr100 thread

"As far as testing...I have a mini-me that I am using to test the digital input on the unit.  The mini-me has both AES/EBU and SPDIF outputs, so I first hooked up my mini-me through the digital SPDIF output.  The DR-100mkII locked in quickly at both 16bit and 24bit and at both 44.1 and 48khz sampling frequencies. "

No word on 24/96 though...

The DR100MKii locks on the SPDIF signal, but not all of the AES/EBU modes.  If I remember correction, for AES/EBU for some reason it locks on 16/44.1, but not 16/48, 24/44.1 or 24/48.  I'm not sure about 24/96, but pretty sure it should be fine from SPDIF.

Back a couple of pages, Todd R got it right.    We interpret the spec as strictly as we can, because it's a liability not to.
If we let a signal with a badly formatted header come into the A/D, it could turn out to have been a Dolby AC3 signal, which would render as full scale noise.  In a product where the user could be wearing headphones with the volume cranked up, we can't take the risk.
Even 48kHz /44.1kHz would produce sample slips which render as nasty clicks.  We don't want the audio to contain clicks that you might miss at first - that gives both of us a bad rep.
With professional gear such as the HD-P2, we can relax the limits a little because we expect pro users to always test first.

If mytek or someone can lend us one of their ADCs, we can investigate relaxing at most the "AES header, but unbalanced signal" restriction.

I must have got this confused with AES tests - (not wanting to use the minime's SPDIF out as the jack is kinda white trash - I had a minime about 10-11 years ago so I know)
