Does travel entail flying? The TSA bin is 25" diagonal and whatever fits in there doesn't need to go through special screening. I carry a 9ft KTek in the OR432 with the side exit dismounted within the case and have never been stopped. Yes the OR432 is 30" long but sitting diagonally the 5-6" depth of the bin allows it to fit-ish. Never has it been an issue. They're probably focusing more on the mixer bag in the KTek backpack.

If you don't require high fidelity and just need to hear the channels/mix clearly, then these work beautifully and can be found for $75 on sale (July 4th anyone?). https://vicfirth.com/collections/headphones/products/vic-firth-stereo-isolation-headphones

Side bar: Ladda batteries are backordered, with no indication on when they will be available again...at the Ikea in Atlanta the manager seemed to think they were going to be discontinued altogether (replaced with another source?) but take that as 100% hearsay. Some locations still have them but no backfill planned it seems.

Still patiently waiting of iOS support I run on a tablet now so no complaints. I love the product (altho I wish I could run Wingman on android but can't due to the newish Android version...)

Superb. I'm doing less 'larger' productions (maybe we all are, unfortunately) so I sold my BS Mag Jr and have been looking for an alternative. The Olympia was on the top of the list but this certainly pushes me to pull the trigger. Thanks a ton for sharing the parts list!

I'll counter that by adding that I have been using IDX batteries exclusively since...well...as far as i can remember in my sound mixing career - let's say decades. I haven't used anything else. Obviously my BDS has changed from basic spliced cables and multipliers, to newer BDS designed for "smart" batteries but only using them for capacity telemetry and not the bells and whistles it offers. I've never had an IDX NP style battery fail me, ever. Sure, some have lost their charge but that is an expected outcome to constant use. I have had issues with V-mounts, but most here don't use that especially if you air travel. Take that with a grain of salt. Smart batteries are great, I see how they have a place in our workflow.

A venn diagram does not allow for Good, Light, Stiff plywood to coexist. If you can weld aluminum sheet(!!!), why would you consider anything else?

I agree on the AC versus battery. Try both and see if the noise is still there. If not, I'm betting it's the cable for sure. 120hz is generally in the bridge area but other anomalies can also cause noise in this range.

^this...and also just process of elimination. I had the same issue as you back when I had a 664 and ran it out to a T4. I just started dipping switches and changing the output selections until it sounded crystal clear. Not scientific, but after I found the settings it was left there until unit was sold and it worked flawlessly.

Still having one foot in the live sector I can attest that this a more a push into regaining that market share. High budget productions, those that are very well funded, are opting for other offerings due to their availability, functionality, and serviceability. Cost generally falls fairly low on the totem poll. Again, speaking here of multimillion dollar productions - traveling, theater, etc. If this is what DPA has introduced to date, I can't wait what the next year has to offer and hopefully it bleeds into the tv/film sector...

Just in case... https://www.forbes.com/sites/suzannerowankelleher/2025/02/05/airline-portable-chargers-fire-destroyed-plane/

Removal and re welding 18650 batteries is pretty easy. Just search YT and you'l find plenty on techniques to remove the bus strip and spot weld. You can find a cheap one that works well enough on amazon (<$50). You'll still be way ahead of replacing it entirely. If they use kapton tape to mask that gets pricey but not entirely necessary - All said without knowing how the batteries are oriented and fitment. Update us please!

It's super easy to get in if your carnet and paperwork are all in order. I've never had an issue and I carnet into the country without really having work booked. Any credential you can provide on your line of work helps tremendously. All this can be gutted, though, if you get someone that woke on the wrong side of the bed...but that's the case in any country really.

Is there a sound report? There should be and I'm feel certain any "mystery" will be solved.

I was going to suggest similar, but with a simple fan, too. It'll ensure all remnants over liquid is evaporated - at least better than not introducing any type of air flow. This has worked well for us in the past when rained out sets occur.
