Ideal for fast turnaround productions where there is no time for post, live broadcast and streaming, preview on set, feeds to video village, IFB feeds, rough guide mixes, and more, the Sound Devices NoiseAssist Plug-In for MixPre-6 II Recorder is used to suppress unwanted background noise instantly. Featuring an advanced signal-processing algorithm, the plug-in reduces noises such as traffic, generators, HVAC noise, and more, while preserving dialog clarity. NoiseAssist continuously monitors background noise to give you clean audio for the entire take.

This version of NoiseAssist provides 2 instances, which can run simultaneously on your MixPre II.

Suppress Background Noise Instantly    For MixPre-6 II Recorder    2 Instances

• An instance is a single occurrence of NoiseAssist. You can set an instance of NoiseAssist to run in one place on your MixPre.
• An instance can be applied to any single channel, any single bus, or mix track (L or R).
• If you have the two-instance NoiseAssist plug-in, you can apply NoiseAssist in any two places, for example, on Bus L and Bus R, on two channels, or a channel and a bus.
• NoiseAssist can be used at sample rates 48.048 kHz and less, and at 24 or 32-bit float bit depth.

Q: 1. I'm primarily interested in using the MixPre as an audio interface. Will a MacBook Pro provide enough power over USB-C or not?

A: Yes, the Sound Devices MixPre-6 II 6-Channel / 8-Track Multitrack 32-Bit Field Recorder can be bus-powered by a MacBook Pro.

Q: 2. I have a power bank with 2 usb-a ports, (1) 5V 2.1A and (1) QC 2.0: 5V 2A - 9V 2A - 12V 2A, in this case do I have to plug both USB-A’s ? Or this could damage my device ?

A: If you’re using the MX-USBY cable you should plug both USB-A ports (Data & Power) into the same destination to properly power the MixPre. MX-USBY: https://www.bhphotovideo.com/c/product/1333784-REG/sound_devices_mx_usby_y_cable_usb_c_to_2x.html We also recommend looking at our Powering Options page to get a list of powering methods that we have tested: https://www.sounddevices.com/mixpre-3-mixpre-6-powering-options/ Any powering method/battery bank not on that list means it has been tested and we cannot guarantee it will work as expected.

Q: 3. Can phantom power be switched individually by channel? For example, two Shure SM86 mics in 1 and 2 and output from a stereo lav system (i.e. Rode Go II) in 3 and 4. 1/2 need power and 3/4 do not.

A: Yes, phantom power can be allocated to individual channels on the Sound Devices MixPre-6 II 6-Channel / 8-Track Multitrack 32-Bit Field Recorder in each channel's menu parameter settings.

Q: 4. How "Quiet" are the preamps behind the 3.5mm Aux input?

A: About as quiet as quiet can be.

Q: 5. The Sound Devices Mixpre series has had quite a few quality control issues. I purchased the Mixpre 6 when it first came out and it never worked. Why should I be confident in any Sound Devices product?

A: Hi Scott, I am sorry to hear your MixPre-6 II "never worked." Can you please clarify what this means? Did you contact our support team to determine what/if anything is wrong with your unit?

Q: 6. Can set up post fade insulated tracks with Mixpre Series II recorders at 32 Bit (to feed post fade signal directly to ISO tracks?

A: Hi Renzo. Post-fade signals are audio signals that are after or "post" the ISO inputs and tracks. Generally, post-fade signals are not sent to ISO tracks. Please feel free to send an email to support@sounddevices.com with technical questions. Thank you!

Q: 7. I'm a little confused. The mixpre 3 ii has a timecode generator, but you have to keep it on the camera? Can't you just jam timecode to the camera then separate them. My whole reason for picking up the zoom f6 or mixpre 3 ii was to get my sound equipment off my shoulder rig

A: The MixPre-3 II has a timecode generator, so it can maintain timecode on its own. As long as the camera that is being jammed from the MixPre-3 II also has a timecode generator, the 2 devices do not need to be continuously connected. However, if the camera only contains a timecode reader, the camera would require a constant connection to a timecode generator.

Q: 8. How does "timecode support" work? How is the timecode generated in the MixPre-6 synchronized with or connected to the camera(s) (Canon EOC Cxxx for example)? I presume when this is done correctly I don't need to record scratch audio on the cameras for sync'ing in post?

A: The MixPre can work with TC a couple different ways: You can set the 3.5mm TRS Aux Input as Timecode in (although that means you won't be able to use channels 5&6 for audio); You can set the 3.5mm TRS Stereo Output as timecode out (although that then means you won't be able to use your mixer's line out); or you can input timecode via the micro-HDMI if you connect your camera's video output (although I've had trouble with introducing interference noise messing around with the HDMI port). So, you've got a few options here. If you don't mind being tethered, you can connect your camera to the mixer and feed timecode one direction or the other. Of course, that will burn an input or output on your mixer and you'll be tied down, so that might not be preferable. The other option (that doesn't require more gear, and won't require you to burn an input/output) is to "jam" sync. Basically, before you start shooting, connect them up and jam timecodes to get them in lockstep. Then you can detach, and even change your settings on your mixer to get your inputs & outputs back. I'm not a huge fan of this method, because some devices lose their sync when you power off & change batteries, so if it's a complicated, hectic shoot and you lose sync for some reason, you might not know till later. Plus, if you've decided to use your 3.5mm in/outs for a different purpose, now you'll have to unplug things and menu-dive to re-jam, which may not be workable in a rush. The third option, which is what I'm planning on doing for my next shoot, is to use an external device (like a Tentacle Sync or UltraSync or Locket Box or Deity BPTRX) to feed consistent timecode into both devices. That way you can set your timecode on your TC boxes, then mount those to your devices and trust that they'll keep everybody marching to the beat of the same drum. For me, this is the best compromise, because I don't want to send TC out of my MixPre (because I need the stereo output for monitoring and I don't want to re-configure on set), and I don't need my aux inputs on 5 & 6, so I'm okay burning that input for my TC in. That said, there's still nothing wrong with getting a scratch track for reference on your camera. It's probably a good idea to have *some* reference audio there for a multitude of reasons. Hope this helps.

Q: 9. How important are the 1/4-inch TRS inputs for event / wedding videographers? Is it more flexible when connecting to a DJ soundboard? Can't decide between Mixpre 3 ii or Mixpre 6 ii.

A: Hi Alex. Both 1/4" TRS and XLR connections are very common at such venues when connecting gear to/from mixing panels. The most important question is: How many inputs do you need? If you feel that you may need more than 3 inputs at 1 time, the MixPre-6 II may be a better option. Otherwise, you may need to confirm in advance of the event what cables are required based on DJ equipment, since the MixPre-3 II does not have combination jacks.

Q: 10. Howdy. Is the 1/8" aux input strictly mono (rather than stereo)? Thanks.

A: Hi David, The 1/8" AUX input is an unbalanced STEREO input. However, it is only MONO when used as a timecode source.
