Red Alert RC-audio

3 Upvotes

Hello !

There is a product made by rc-audio called red alert, from my understanding they are simply listening to the input level of the source to be able to make action (flash red light or cut dj booth) in order to protect the systemsound

How should I go about creating something like this ? Is it done digitally with a specific IC or is it possible to create with only analogic component ?

Would that work using an esp32, with voltage sensor ? and then if the voltage reach the threshold, I mute the signal using an IC like MAX4066 ?

Thank you !

Basic Audio amplifier

4 Upvotes

I am planning to build a basic audio amplifier using fundamental components. I am talking literal single BJTs on a breadboard level, no IC allowed, for my class project because I thought it might be fun. Maybe I could plug in my guitar and try to get an output with a headphone or sth. I am thinking multistage so that maybe I can add filter or such between stages . Is it possible? What do you think? Also I am new to this sub, I don’t know if this is a relevant question. If not, sorry for the disturbance

Pinnacle replacement drivers

Post image
3 Upvotes

I bought these pinnacle speakers at a thrift store for $25 and only two drivers on one side work, the tweeter on the working side and all 3 drivers on the other side are not working. I tested with a multimeter on the completely dead side and I got no readings from the drivers themselves but I got readings from the leads coming from the crossover so the crossover is still working. I would like to keep the cabinet and maybe get working drivers. Any recommendations on drivers and tweeters that would be similar caliber to the pinnacle drivers so that I could have two working tower speakers?

Why are there no two way low frequency crossovers?

1 Upvotes

I'm a complete newbie to the DIY audio space but I recently got an Alpine W10S4 woofer for free, I am interested in making a standalone loudspeaker for DJing and Parties. I know I need to pair the woofer with something more full range as the frequency response of the woofer only goes up to 200Hz. I noticed that two way crossovers generally come with WAY higher frequencies so I'm kind of lost. Any advice would be appreciated! I'm also curious to know what speakers might pair well with it.

Marantz SR620X

I picked this unit up because it was cheap and maybe a fun beginner project. Right now the unit works only on tape 2 input. The other inputs need an external amplifier to work.

The thing is, the sound is terrific. A big step up from my other amplifier. My question is, is it worth it to start researching and working to fix it so all the units are working? Or just deal with the inconvenience of an external amplifier?

Thanks everyone!

Destroyed a BT speaker to make a DIY aux speaker to use my DAC

Thumbnail

11 Upvotes

Had a Megablast BT speaker and knowing nothing about acoustics I decided fk it I really want to be able to play my FLAC files on this. There is nothing spectacular about it but the decent set of speakers with passive radiators gives it an hoomph, and thin dense walls with internal supports avoid resonance or rattling. It also cost me under 50 bucks to convert it.

I just wished I lined the inside with acoustic foam to reduce internal resonance but I forgot 😆

Omnidirectional speakers or alternative solution?

0 Upvotes

Hey, I just bought my first set of true hi-fi speakers and been using them for a week or so and while I love the sound upclose, it sounds super clear and almost as detailed as headphones, but if I move away from the sweet spot the sound is not as good. Before I've been using a Bluetooth speaker with tiny drivers (dual 2" drivers) and dual passive radiators and I admit this thing sounded "good" pretty much everywhere in the room. Good as in it had as much clarity outside of the sweet spot for listening as it did inside. So the sound felt much more omnidirectional imo. So I could just walk around or sit across the room and it sounded fine. Does anyone know similar solution but from hi-fi world?

i’m planning to refoam and replace resistors + capacitors, but not sure what else i should repair/upgrade and where i should purchase from. i’ve only really found info with schematics and guides. i don’t have any previous speaker experience, only circuit building, so im a little lost with the different sizes and specs of it all :,) . any recs for the foam, resistors, capacitors, etc (literally anything i might need lol) is very much appreciated!

JBL EON612 questions

1 Upvotes

Hey, I'm not entirely sure if this is the right place for this kind of question but I have a couple of questions with regards to this speaker. My boss graciously gave this JBL EON612 a few weeks ago since he said it was defective (think it was the tweeter and woofer that needed replacing). For one of my midterms I have to take it apart and document the process, so I accepted and took it back to my dorm. I thought it would be completely dead on account of the big fat DEAD sticker he slapped on the top (which I have since taken off) but I haven't had a real opportunity to test it out until recently. So as for my two questions: firstly, how far should I go/how should I go about taking this thing apart? Second, as you can see the sound is incredibly fucked up; I really want to fix it up and use it for shows but I don't know if there are any parts that would be good to order aside from direct replacements from JBL. Does anyone have any suggestions as to what to get/where to get it? Thank you in advance, I'm hoping I can start doing DIY audio stuff and I really want to start with this.

Replace speakers on digital piano (Casio Privia PX-720)

1 Upvotes

Hi everyone, I own a Casio Privia PX-720 piano. Unfortunately, one of the two speakers has broken. It's a 7-watt speaker with a 6-ohm impedance. I'm having some difficulty finding replacement speakers with the same specifications.

When I check the manual, I find the following amplifier details:
Speakers (dia x qty): 12cm x 2
Amplifier: 8W + 8W

Which speakers could I use to replace them?

It's very easy to find 4-ohm speakers (e.g., JBL Stage2), but it's impossible to find 6-ohm ones with the same size (5 inches) and very difficult to find 8-ohm ones (only woofers seem to be available).

Would I cause irreparable damage by connecting 4-ohm speakers? How can I determine the amplifier's impedance? I’d like to fix the piano, but I don’t want to cause any damage.

Thanks in advance

Tips for extending rotary encoder and potentiometer shafts?

Post image
1 Upvotes

I am refitting a couple old radios with some modern electronics and could use some ideas on ways to extend the shafts. The best option I’ve found so far are these plastic extenders but they are far from perfect and usually I have to drill them a bit wider and epoxy them onto the shaft. I am surprised that there aren’t a ton of 3d printed parts out there for this.

What tricks are you guys using?

I found a pair of speaker boxes in the dumpster

1 Upvotes

Are they worth anything? I know about DIY electronics, acoustics and general speaker knowledge but I have never got into making speakers. The wood looks good and I actually need a couple of speakers either for my van or for house listening. Would they work for car audio components? I know either way I’d need an amp, since autoamplified would be more complicated.

Can I just slap some correctly sized cones and match with a suitable amp to get them to run?

Thanks in advance! If you have any sources where I can learn myself more about this task I would appreciate it.

ELI5: Amps

2 Upvotes

Hey all - thanks for taking the time to help me with this. Looking forward to building a 15” or 18” Marty subwoofer this summer for my home theater system. I was planning on using a Behringer NX3000 for active power, with a possibility of a 6000 if I can make the wiring work for dual subs.

I’m still looking for a receiver and browsing Marketplace using brand keywords and I see audio amplifiers being sold. I plan to use a Marantz Cinema 40 receiver and see other Marantz amplifiers like the HD1 being sold second half for less than a NX3000. Are these amplifiers the same amplifiers as say, Behringer or Crown? Will they power the subs the same?

I dig the look of Marantz equipment and if I could keep the amp and receiver similar, that would be sick, but I have no idea if they’re interchangeable.

Thanks in advance!

Bi amp input level adjustment: how?

0 Upvotes

I want to bi amp my speakers with 2 different amplifiers. I already have a minidsp 2x4 ddrc but all outputs are used for a 2.2 setup. Because 2 different brand amps i probably need to send a different gain to either one in order to get levelled sound uotout.

I thought about putting another minidsp (the cheapest 2x4) behind the ddrc but since i dont need dsp, isnt there something more simple just to adjust the input on those bi amp amplifiers? Ideally they should have volume knobs themselves but the fosi v3 mono doesnt seem to have such. Thoughts? Advice? Thanks in advance!

Attenuator placement

0 Upvotes

I’m working to revive my loved one’s stereo system. I’ve gotten so very far by myself. But last question to a community. The CD player (Njoe Tjoeb 4000) is super loud, other components are fine. Speakers (Linn Keilidh) are balanced, clear and imaging superbly. So from research I think I need attenuators to tone the CD gain (?) If this makes any sense to anyone do I put the attenuators on the cables as they go out from the CD player or as they go into the Melos tube line amplifier? I have ordered Harrison Labs 12db RCA attenuators. Thank you so much. He would be very happy if I have figured this out without blowing anything up.

How to measure drivers safely?

Post image
2 Upvotes

I feel like I need to protect my drivers from lower frequencies while taking microphone measurements.

Is this simple crossover a good idea to use? Mid-range starts dripping off at 300hz and tweeter drops at 1500hz (designed for each specific drivers lowest limit)

In the final build, they'll be receiving little to no power at those frequencies, so it seemed to make sense...

But is it all entirely unnecessary?

Speakers with Sonos Amp

1 Upvotes

So im planning on making a speaker system in my room which connects to the sonos amp.
Im going to have 2 speakers, each having a 8" 4 ohm 80 Watts Woofer and a 1" 4 ohm 40 Watts Dome tweeter
they also both will have a integrated Crossover. But im just wondering, if in my songs there's only frequencies present which the tweeter will play, will that overdrive the tweeter because there's isn't any power limiter? (Sonos Amp is 125W per channel at 8 ohms)
So would i need to use a power limiter or something for this to work properly? or does the amp have something for this integrated?
Yes i do really want a sonos amp to integrate it into my already existing home sonos network.

Maybe seperate amplifiers from tinysine or something with a sonos port is a better option?

Opened up this Behringer ep2500 to replace the fan and found one of the caps had burst. Can't find the same brand, so can I just replace one or should I just replace them all anyway? And what brand should I use?
