Is the plan still to sell these or the design/BOM? I would absolutely love a couple of these for my desk! Would happily pay for print files + component list!!

I would have liked to see a a close-up of the bottom of the Sonicare - they have so many models, I’m not sure if the one you have has the same bottom as mine (HX6521/01 bought in 2020.) Since my problem was the toothbrush turning on by itself and the front button not shutting it off, I had to pry off the bottom and stop it - gave it a cleaning to get rid of the condensation and it works OK. I didn’t mess up the bottom enough to stop if from working.

I want to share an experience i encountered in an outdoor event ( 2 subs and 2 jbl line arrays on each side they were same height and arrays were put on high with a pole mount maybe a max height of 8-9 feet as the subs were some high model style anyways . My concern or question is the subs had no issues I was able to hear them from far and close distance but the for the mids and high frequencies I was able to hear strange things happening to the sounds ; it was like when the wind blow the sound faded drastically almost felt like the sound was muted and only bass was on . I was maybe 40 feet away from the stage ( there was much crowd to even block the sound or view . Do you know of the why this happened or nothing like these has happened we were in a park they rented the power generator and it was plain day nothing like running so much lights . Will these also happen it it wasn’t line array and more like the normal speakers that have a wider tweeter horn ? This was not my system but a local private event .

This was super helpful, especially as I'm starting out with repairs in the industry. Thanks Dave!

WAS JUST ABOUT TO DISCONNECT MAIN BOARD AND SOLDER OFF... CHEERS DAVE.. TOP IDEA..

Needs an update for 2024!

Great. I opened my tootbrush without any damage. And then fixed it. Thank you! Ps. I used duct tape with bolt

This is adorable

Ok. I’ve got the guts out. I go to tighten the screw - and there’s no screw. She’s gone missing. How do I find what I need?

Beautiful ❤❤❤❤❤❤

the opening the back with a screw is genius, never saw that before

Thanks. Save me a lot of time

Hi Dave. New to your channel. I play in a duo that uses tracks for bass and drum. We often struggle to be happy with the sound of the tracks. For larger outside venues speaker placement is always a question. We also play with the EQing to try and optimize the punch. Do you have a video yet that shows how to optimize drum and bass coming from tracks and also talks about speaker placement, depending on the type of venue, whether they’re outside or inside. We are also interested not just in placement but speaker types if they also have an impact in optimizing our base and drum track sound. Thank you for your help.

Cheers Dave, i feel more validated for my sedimental purchase of an old Perreaux 9000B.

send hot, turn down late.!!! Gain structure is not just the mixer, but then entire signal path all the way to the speakers.

I remember that grin. Pinned to the back wall of a hall too small for Steel Pulse's PA. Looked round to see other grinning idiots. If you can't hear it with yer belly it ain't low enough!

Unfortunately IMO, most guys don't think like Dave, who is doing aux fed to get to rid of low frequency garbage. They do it for that reason, but what they really like about the method is now they can go BOOM BOOM BOOM with the subs and impress everybody. This is not the music doing that, it is the mixer. When I see live videos of bands who don't have huge low end on their records but have BOOM BOOM BOOM in their shows, then it's clear it's a useful technique that's been abused by mixers to the point that it's now the norm.

Woohhhh what is the brand name of this monitors???? Can I play my guitar into it via multi effects unit ?

I’ve been wondering something similar, let’s say a smaller box that cost half as much like the hdl6a vs having half the amount of a larger box that cost twice as much like the Hdl20. so would a 4 hang hdl20 rig be louder then a 8 hang hdl6 rig? does the maximum spl rating plus 6db every time the amount of cabinets is doubled apply to this?

thanks Dave! I went with the purple sound tools cable at 45M and been having great results, and I feel like I don’t have to worry as much about people stepping or pulling on it

How to fix leaking of coffee

I would enjoy a follow up video discussing headroom. As audio engineers we all know that it's best to run any system at somewhat less than 100% of its capacity, but how much headroom is actually necessary, and where do you start to see diminishing returns from adding system capacity at a fixed volume level? If you want to mix at about 95dBSPL you want a system that is capable of throwing more than that, but how much more? 105dB? 120? 130? At some point you're just wasting money, but I've always just kind of estimated how much headroom is ideal and never gotten really scientific with it.

AH the age old conversation between audiophiles and audio engineers..... LOL ...

We'll just go and buy Amphenol. Simple....

smart!

Thanks for the tips Dave! Been working in a venue 6 1/2 years now, and your explanation of eq’ing the system is the best I’ve heard. Appreciate it brother.

pardon my ignorance, ethernet/network switches are incompatible w/ the data transmission protocols in pro-audio? (these days switches introduce latency under 0.1ms)

Audio nerd AND proud Sonicare repairman thanks to you! Grateful!

DAVE !!!! Why are you not measuring Total Harmonic Distortion ... Freq response is 1 thing.. THD is another ... I'm disappointed that your experiments did NOT take distortion into account, other than clipping, Which is audible. ... THD will impact the 'listenability" and ear fatigue over time.

I've literally been studying cables with this kind of tie. Like, for real looking at it like 'HOW?!'. THANKS!

The SoundWire adapter is amazing. Its ability to protect computer equipment from serious damage should a phantom power mistake occur makes the price of this device a good value.

Are times still fast down there at ridgemont high? But in all seriousness, this is really helpful. I wish I could get your IRL advice with my very limited live setup, trying to make the most out of it. I'm working with a group of 4 to 8 musicians (cover / tribute circuit), using a medium format mackie board. I never necessarily intend on becoming a sound guy... I just started as key / drum tech / roadie for these people - 6 months later, I'm getting put behind the board. It's been a fun ride, but I'm still trying to find my way.

I agree with the workaround Dave. Thanks for the response.

I imagined the horizontal line array would have been the most efficient by using the ground boundary but it seemed like the vertical line array was way better

2:15 very cool.

I really dig your videos brother. Thanks for sharing so much hard earned knowledge.

wow that’s a much more bounded saturation than i was guessing it would have, almost sounds a bit like hard clipping (but of course proportional to the wavelength)

It's actually pretty hard to clip the x32 in practice if you're staged right and the rig is sized right. But then again there are plenty if amateurs out there.

👍good info

Apologize if this is a bit off topic, but Dave, have you or anyone had any luck driving production intercom over Ethercon/cat cable? Have tried multiple cables and break ins/outs with no luck. Trying to cut down on the analogue cables deployed from stage to FOH in the main bundle/snake. Figured it has something to do with the call shunting/grounding etc.

I hope you are very proud of yourself. This is an excellent video, but you already know that from all of the positive comments. So instead, I thought it'd be cool to paint you a picture of how awesome you are. Let's assume every person that left a comment fixed their toothbrush after watching. There's 500 comments, but you replied to most, so let's say 250 people. The price for a Sonicare ranges from $30-$90+. So lets just use $50 as a rough guess for an average. That's $12,500 that you collectively saved people. But wait. How many views do you have? 117k. I can't imagine that people are coming here if they don't have one or aren't intending to fix it. So let's grab a safe number, a bit less than half the people that watched the video attempted to fix and were able to fix. 50,000 people. Dude. That's freakin' $2,500,000! Two point five million dollars that you likely saved people!!! Could be more! Who knows! Regardless, whatever the true amount is, you have clearly made a huge impact on people's collective finances. Super cool!

Since we use digital “snake box/stagebox,,,what i understand is the heart of the system switch from the console to the stagebox,and the console become the “remote” just like midi controler…but i might be wrong😅

You are so good!!!

Hi Dave, I love your analogies for conveying engineering concepts with intuition. I was hoping you could apply your science communication skills to a simple question that has been bothering me for ages: In power engineering, we use a transformer at the source and to step up voltage (and step down current) to maximize the efficiency of long distance power transmission. In audio engineering, we do the opposite; step down the source’s voltage and step up the current to maximize the efficiency of long distance signal transmission. How would you explain in an intuitive way to, say, a high school physics student, why power vs audio engineers do the opposite? Thanks, Brian

The ultimate board. A step backwards. Analog i/o and mix, digital delay and reverb. Period

Dave you are absolutely phenomenal. I so appreciate your no bullshit approach.

would be awesome to see a custom prototype at 140m-150m layed out with no joins, id be amazed if you couldn't get a solid 140m signal! purely to fun of course, 130m is going to be massive for most gigs out there, no one wants to run FOH over 100m from the stage :P
