Have you tested the cable to make sure it is wired correctly?

ugh, yep. the cable is bad. it's essentially a 1/8" stereo TRS to 2 (two) 1/4" stereo TRS (not as described). junk

(edit: setting Channel 3 - usb-1 to phase inverted as a work around)
Well glad you got it figured out, and glad it's not a faulty SD machine!

in general how long does it take to write a set or say 2 hour show to usb?

Write speed to my Cruzer Fit was about 3MB/s.
And write speed to a 64MB Samsung Drive Fit MUF-64BB was just above 10MB/s.

I picked up the SanDisk and it is indeed slow.  I didn't do the math but 10.6 gb took about 24 minutes. Going to try the samsung and see how it compares.  The bb are not available but these are....

Got the Samsung in today and just tested with the same 10.6gb files.  Took 15 mins so much faster than the sandisk....

Does the MixPre-3 have the ability to be used remotely with a timer where I could set the timer to turn on say at 6 pm and turn off at 6 am?

The SD722 has that ability but I am unable to find the topic in the MixPre-3 pdf guides. I would really like to suspend recording 12 hrs of the day.

Not that I know of, sorry.

MP-6 mkII arriving maƱana, to replace mkI running 2.21.08 firmware. (Hey, it's rock solid, and I start recording a half hour before the show so pre-roll not a big deal for me.)

Wondering how y'all run them compared to the I. Levels to 11?

Firmware-wise, seems like only big change is addition of pre-roll. Anything else of note?

TIA

You can also lock the controls with newer firmware!  I don't use that feature, but it is nice to have.  File backup to usb drive is also nice.  Don't remember when channel linking came into play, but maybe 2.21 has that feature.

Locking controls will be great. Does Wingan still change things when the unit is locked?
USB stick work as a drive in this scenario?

Wingman only stops and starts recording!  I'm not sure if the controls are locked if that also locks the Wingman app.  My hunch is no.  The USB backs up the recording after a show is finished.  Next time you turn on the recorder if you have a drive in the USB it will start to transfer it to the drive.

If you already have the usb in it will start when you stop the recording.

MixPre v1 now have this in firmware (7.10) as well.

v7.10 Support for front panel lock

Page 22 - Press channel knobs 1, 2 and 3 simultaneously to enter the Front Panel Menu.
ps - oh and by the way, I only have 1 ticket and like 5 posts b/c this is a new screen name. My old one was "eclark" but I had someone that was taking tickets from me like everyday and I didn't want to deal with it so I just signed up for a new name.

Gain question related to Mk II functionality.

1. Over recording isn't an issue, so no need for fast/easy gain reduction.
2. Why not set input gain with wanted boost, rather than using knob to add post-fade gain?
3. Doesn't input gain add less noise?

I use custom setup, with gain set to basic, maybe I can't access this control setup?

Has anyone used a MixPre USB input to patch out of another MixPre's USB output?
You'd probably have to power via the Sony N mount or perhaps that 8-pack AA sled...
I was just thinking how this thing is a great recorder, great preamps, but has a lousy output stage with nothing but the mini jack...


...nothing ANALOG, that is!??!??!??!?

Mixpre Firmware 7.14 is released. Adds Low Cut Filter option at 100 Hz

https://www.sounddevices.com/download/
They updated the user manual to reflect changes

Quote
LOW-CUT FILTERS
40 Hz to 160 Hz (adjustable), 18 dB/oct. First stage analog, subsequent stages digital

https://cdn.sounddevices.com/wp-content/uploads/2021/08/MixPre-Gen1-User-Guide_8.11.21.pdf

edit: the channel indicators now pulse red on peaks, green for medium signal, and off for muted!?
That's different!
Brightness can be controlled via very confusing LED screen which lists the LED for the screen on the left, and the knob surround brightness on the right.

I still wish they'd change the label of PHASE to POLARITY invert.

more edit:
I have been using the Mixpre6 as my daily USB audio interface for my mac, and found that I prefer powering it via the supplied USB-C cable with the Y-connector for the dual A plugs, because I can put the power one on a brick, and the MixPre won't power down and cause my stereo to hum and click every time I reboot.

After installing 7.14 firmware, I noticed that the power indicator was amber, not green, as though it was only getting power from the data connector of the Y.
I wiggled the power plug of the Y and the green came back on, but would not go green reliably when plugged after unplugging until I rebooted a few times.

Once again, I regret updating firmware the first day it's available.
Hoping for 7.15 soon.
Quote
New
Added 100 Hz Low Cut Filter option.
Fixed
Gain ranges are now always correctly applied after loading settings.
Ring LED brightness is no longer affected by channel mute status.
Opening a Song Project from Audio Mode no longer incorrectly opens the last Song Project instead of the selected Song Project.

Interesting - on my MixPre6ii & MixPre3i w/7.14 a muted channel is still red. The brightness menu still says LCD on the left and LED on the right like it did before...are you thinking something has changed? If you didn't delete the old firmware file you can load it - just hit cancel when it prompts to confirm the firmware name and it will cycle through all the firmwares you have on the SD card.

I'm happy they fixed the bug where I had to load a music file twice to get the right one to load - valuable only to those that use the Musician Plugin, but it was pretty annoying.
