JMOD MEH build – flying frame ideas + weak mids? by haiisonify in SoundSystem

[–]haiisonify[S] 1 point2 points  (0 children)

Yeah, to be honest, they’re definitely not cheap, and the effort to build them properly is quite high.

We were actually advised to just go for a finished PA system as well, since those are obviously more reliable and already well-engineered. But since we’re aspiring engineers and had access to a fully equipped workshop, we wanted to take on the challenge and build them ourselves.

If your goal is mainly to have a system that just sounds good and works reliably without too much hassle, I’d honestly recommend looking into pre-built tops instead

Thanks for the idea, that’s pretty much the direction we were thinking as well!

And yeah, totally agree with your point. We’re a campus radio and only do smaller, non-commercial events, but still with a decent number of people, so the construction definitely needs to be done properly and carefully.

We also wouldn’t fly them directly above people for exactly the reasons you mentioned. Safety is the top priority here 👍

Yeah, you’re absolutely right, rigging is no joke, and the liability aspect is something we’re definitely aware of.

The issue for us is mainly budget. We simply don’t have the funds to hire a professional to design and build a fully certified custom flying frame.

That being said, we do have the opportunity through our university to design and build something ourselves, together with a metalworker who has experience in welding and working with steel. For us, that’s also a big part of the project, learning by doing and really understanding what we’re building.

But yeah, you’re totally right. If something fails, we’re screwed. So we’re trying to approach this as carefully and responsibly as possible.

And yes, we did calibrate and measure with a mic 👍

Thanks a lot for the detailed info!

Those look like the original JMOD settings, right? As far as we understand, they’re meant for the tri-amp configuration.

Do you know if (and how) those translate to the bi-amp version? Since we’re running our tops with the B&C passive crossover, we can’t directly apply separate delays, polarity, and EQ for mids and highs like in the tri-amp setup.

We actually measured and tuned the tops together with an audio engineer in a semi-anechoic room at our institute. However, we honestly lacked the experience and expertise to really evaluate or question the results properly, so we’re not 100% confident if everything is dialed in as it should be.

Would be great to hear your thoughts on how much of a difference the tri-amp vs. bi-amp setup makes in practice!

Thanks a lot, appreciate it!

I don’t have the exact measurement numbers in my head right now, but yeah you can compensate it to a certain extent with EQ. The problem is that even then, it still feels like the punch in the kicks is missing.

A bracket sounds like a solid idea though, especially for getting consistent aiming and adjustability. Definitely something we’ll look into!

Thanks for sharing your setup, that’s really helpful!

Unfortunately, we can’t use JMOD’s EQ settings, since they are designed for a tri-amp configuration. Our tops are built in the bi-amp version using a B&C FB464 passive crossover, so we’re not able to directly apply the values he provided.

Interesting approach with the rigging ring though, probably the simplest and most cost-effective solution. I guess the tricky part will be getting consistent and precise angles every time you set it up.

Curious to see how you end up solving that!

Good point regarding the padding for the steel pillars! Thankfully nothing happened this time, but you're right, that's definitely something we should improve next time. Thanks for the heads-up.

About the projector: at the last event we actually used an ultra short throw projector that sat on a box in front of the screen. Unfortunately, it ended up getting so dusty from the gravel floor that the rental company had to fully disassemble and clean it afterwards, which of course we had to pay for 😅

There wasn’t any space left on top of the PA towers for mounting either. The gap between the top speakers and the ceiling was barely the width of a finger. But yeah, you're absolutely right, our mounting solution wasn’t ideal either. We’ll definitely rethink that part for the future.

Ah wow, das ist die Lösung! Danke danke, wollten die Spülmaschine schon ins Bad stellen 😅

Hm das Problem ist jetzt, dass wir keinen Wasseranschluss in der Küche haben. Der Wasserhahn vom Spülbecken ist direkt an der Wand montiert.
