I'll stick with my original!!  It has been solid.

yeah i put mine up for sale this morning and was quickly followed by two others. I'd been meaning to list it anyway, moreso because i probably wont be doing any open taping till next summer. not going to firesale mine tho, its a great unit. if it sells it sells, if not, im happy with keeping it.

Not seeing a big advantage to the upgrade.  Unless I did the Mixpre 10, which is way cheaper than the original.  I haven't been taping a lot the last few years and never run more than 4 channels so probably a waste of money.  I'll hold out for the version III  :bigsmile:

generic response from SD to my tech support request

Out of curiosity, have you tested standard SD cards that are Class 10?
On Taper Section, most of the cards tested are µSD card which is not recommended. We do see that three standard SD have been tested but have multiple cards of the same model been tested? Not all cards are created equal even if it's the same model.


bolded part is news to me....i replied that its not practical for consumers to test multiple numbers of each type of card

why would anyone use a micro with an adapter instead of a full size SD card?

micros offer identical performance and are universal in more types of equipment. My A10 or R07 cant take full size SDs, and if im testing cards i want to find the fastest micros as well

Full size SDs are mostly an empty case, they use the same types and grade of memory inside.

https://youtu.be/1W4UScF4GaA?t=61

There are literally *dozens* of UHS-I microSD cards that can sequentially write in excess of 10X the paltry 4MB/sec we need or 8 channels of 24/192.

https://havecamerawilltravel.com/photographer/fastest-microsd-cards/

look at the top speeds of the full size SD cards - Exactly the same! for UHS-I as well as UHS-II.

https://havecamerawilltravel.com/photographer/fastest-sd-cards/

sorry, blaming microSD is a poor excuse by sound devices, imo. Esp considering even among full-size cards tested in that thread only 1 out of 4 actually worked at full bitrate (about statistically the same as the tested micros in these limited sample size). I cant comprehend how they have a 10T spec'd for 12 tracks at 24/192 when the mixpre-6 cant reliably write 8 of those channels with properly spec'd cards. I guess nobody uses high bitrates in the real world?

would have been a huge upgrade if the mixpre-IIs were UHS-II compatible. in any case it needs to be solved. I dont know what kind of buffering the mixpre uses if any, but something like 512MB of fast buffer memory is a tiny onboard chip and would be nominal in cost

Theres prob a reason the scorpio uses an SSD - even thought its maximum bitrate is 17MB/sec and well within the sequential write rates of most modern cards

If camera manufacturers can integrate UHS-II/v90 support, it seems like this would be obvious for high-bitrate audio applications. id love to buy one of the cards that can write at 200+MB/sec but none of our gear supports it

Here are two good discussion threads on JWSound you might all be interested in.  Paul is active on the first, and Jon Tatooles (also of SD) is active on the second:

https://jwsoundgroup.net/index.php?/topic/34175-the-new-mixpre-ii-are-here/&
https://jwsoundgroup.net/index.php?/topic/34174-floating-point-v-fixed-point-wav-files/&


In the second thread above, Jon linked a page on the SD site where we can now hear some music recorded in 32-bit float on the MixPre 10 II, at 3 vastly different levels:
https://www.sounddevices.com/noise-in-32-bit-float/


Paul, if you are reading this, I request that you please do same with some very dynamic piano music.  I know that is right in your wheelhouse.

am doing some testing at home and the mixpre didnt write a file header- how to fix? its a 6channel and i cant open all 6 channels in soundforge as a .RAW file

EDIT: I popped it back in the mixpre and played it, then ejected and put it back in my computer, and it had a header

Sold my mixpre-6 on ebay and now the buyer sends me this message:

"Ive contacted Sound Devices to confirm, but it seems this unit is defective. The volume knobs do not light up when the mice are active. They are supposed to display the color green or red depending on if it’s clipping or not! I’ll wait until they get back to me but if that’s the case I’m going to have to send this back to you."

Has anyone had this issue? I only powered mine with Sony camcorder L-Mount batteries and the knobs always lit up for me. Maybe it behaves differently when powering it by USB?

they light up using usb as well.  that said they only light up when getting good levels.  if he just has it turned on with no real gain being input then there would be no color on the knobs....

You can set the LED brightness in the settings he probably has them turned all the way down.

Either that or he’s bullshitting you and has buyers remorse.

He just told me he's used USB ext power, USB to a laptop, and AAs... and that he updated the firmware. (I never updated the firmware since I had no need to).

I asked him to send me pictures of the unit with levels hitting 0 and the knob lights off and pictures of the setup screens for one of the channels with no knob light.

The knob lights were lighting up like christmas trees when I used the unit at Dead & Co and Dave Matthews a month ago. This pisses me off.

I PM'ed Paul Isaacs. Hopefully Paul can get him in contact with the right people in support to help him configure it correctly because ebay always fucks the seller.
