Topic: Sound Devices MixPre-3 and 6, Part 6

[DavidPuddy]

I’ve used a pair of Line Audio Design CM-4 mics on 1 and 2.  When I used the Sennheiser AVX on 3 and MKH416 on 4, it’s apples and oranges.  Same apples and oranges yesterday with a line feed from the soundboard on 1 and MKH416 on 4.  The levels in post were different but that likely because I had a lower gain on 4.  I can do a test of the pair of CM-4s on 3 and 4 but I don’t have much time available for the next week or so.  If no one else can test their MixPre-6 II, I can do it.

Thanks Rick. I encountered the issue for the first time on Saturday night at a show but confirmed it a few minutes ago using my stereo.

Okay, how much additional gain should I add so 4 matches 3 sound levels?

Looks like I have a problem with channel 4 of my MP6. At some point, it has started running 12+ db below channel 3 when running a pair. Tested the same mics with channels 1&2 and they're as normal. Anyone else had this problem develop?

are your channels linked?  balance at 0?  any chance you changed the actual gain in record settings (not on knob) my accident?

Off topic, but what is this and why do we need to know about it?
Please just say "it's nothing, never mind, I can turn off the feature where it automatically ads an advertisement to every single thing I post online."

Tapatalk automatically adds an annoying signature!  Easy to turn off but most users don't realize it.

Some people don't read and participate on ts.com via a web browser when using their smartphones, but, rather, rely on an app called Tapatalk (https://www.tapatalk.com) to do so.

Seems i find a firmware bug, or my device is broken. Can someone check if same problem exists on first generation of MixPre-3?
It seems something wrong with headphones output or some kind of internal routing headphone levels problem. Here is example:

If i connect MixPre-3II as USB audio device to listen music from computer and monitor with MixPre-3II Headphones-out, (headphones volume set to 75) it produce a lot of background distortions. No red clipping indicator in the corner.

Here is a sample test file with deep bass to playback: https://www.dropbox.com/s/1e0mk5fkqumhh63/SystemLog-Off.wav?dl=0

 I record a video to better illustrate this problem. Headphones placed very close to smartphone microphone, so in the end you can hear those actual noisy distortion clicks. Take a look https://www.dropbox.com/s/ywb2xfquhs6wvay/IMG_7665.mp4?dl=0

P.S.
I got same results if i upload file to SD card and playback directly fromMixPre-3II file system.
I can hear distortion with large headphones if i increase headphones volume to 56 and higher.
I can hear distortion with small plugs headphones if i increase headphones volume to 36 and higher.

UPDATE.1 Final respond from tech support - it is most likely hardware problem with my unit. So i need to send it back for exchange.
UPDATE 29.11.2019. Replaced item arrived and it have the same problem. So it looks like some global headphones preamp hardware or firmware problem for me.

Gordon, I’ve looked on the Tapatalk settings on the iPhone but I can’t see anything related to the default signature.  Hint?

Look at: Tapatalk > Settings > Signature

[rick.lang]

I’m on an iPhone on the free version. I don’t have a Tapatalk Settings or Signature menu.  Sorry if it irritates some folks.  The FAQ implies the signature can be turned on from a paid subscription:


“How do I get rid of the popup and/or smart app banner that appears on my site after I installed Tapatalk?
You can disable the popup by logging in to the Tapatalk Site Owner Console. However, to disable Smart App Banner, it is part of the Basic Paid Tier at $5/month that also includes removal of post signature and other branding control.
Tapatalk is free but we do charge a small fee to make this service sustainable.”

I do occasionally use the desktop to access forums via a web browser, but the convenience of working from the smartphone means 99% if my forum activity is via the phone and Tapatalk.

How can an app not have settings? Could you possibly not be looking in the correct place?

From my Android version:
Open Tapatalk (The app, not the specific link to this forum. You won't see it if you do that.)
Click on your Profile icon (silhouette of a person, last icon in the row across the top)
Click on Settings (third option down, between My Account and Contact Us)
Click on Signature (third option down, below Subrscriptions)
Click on the slider to turn off your signature.

Oh my!  Can’t believe I haven’t used that part of the interface.  I was just focussed on the controls that are open to iOS in its Settings for the app.  Thanks for that help.   Signature has been deselected!

New

• Support for optional MixAssist automixer plugin.
  MixAssist reduces ambient noise and reverberation when mixing and recording with multiple microphones.

  The MixAssist Plugin is available for purchase at the Sound Devices Plugin Store. (available for MixPre-3, -6, 10T, -3 II, -6, II, and 10 II).
  Flexible USB Output routing. The new USB Output routing matrix allows control of what signals are sent to the computer and in which order they get sent. The matrix allows for mix-minus and selection between pre-fade vs. post-fade isolated channels (M models and music projects allow post-fade only).
  Sound Reports added to MixPre-3, MixPre-6, MixPre-3 II, and MixPre-6 II.
