Visualizing the Spectrum? AK Technologies AK2515 Audio Spectrum Analyzer

Old school EQ's with spectrum analyzers are getting very expensive and hard to find. I recently came across this 25 band spectrum analyzer by AK Technologies. It is reasonably priced at $45 currently and looks SO good. Check it out and the links below if you are interested in picking one up!

I don't know why these spectrum analysers are not in stereo or AVRs anymore. They made the system looks so beautiful when playing. My dad had a Kenwood and I could sit and watch the light and analyser all the time when my dad was listening to music, and they were so beautiful to watch. 😂😂😂

Thanks brother, I appreciate the comment

[@RadiOG58]

Yes!!! So cool to have those old skool visuals with new school equipment. There are only so many stereos with spectrum analyzers so this definitely has a place. Kind of hard finding the older EQs with a spectrum analyzer and hard to justify buying one when stereos have the same capabilities inside now.

[@wal]

Yes very true. We really just need the visuals anyway

[@californiakayaker]

Have you ever tried this with pink or white noise (or maybe some sort of easy sweep generator? I've seen them as android apps) ? We've got a special ham radio application we are trying to set up so we know more about what a "repeater" sounds like. A "repeater" is a special fm radio on a mountain top that picks up weak fm radios and transmits them to the other side of the mountain for instance. The spectrum on some repeaters (especially ours) can be messed with to the point where you don't know what you've got. Its radio audio and every radio messes with the audio specrum (FM Pre-Emphasis and De-Emphasis). We have a volunteer group with special repeaters (ham radio) trying to fix the audio so every repeater sounds the same. The end gadget needs to be inexpensive, easy to replicate, and easy to power.

[@scottkelmer436]

Thanks for the video! I saw this on eBay, but wasn't sure how big it actually was, or if I could use it as a display for my home audio, or if it had to be installed "IN" something, or if it had to be soldered, or plugged in, but you just answered all of those questions! Very helpful!

Love these. My dad back in the early 80's had one for his home audio racks. Used to watch the lights for hours. Make me want to install it in my truck .👍🏻

[@FrankFactor]

There is just something so cool and satisfying by being able to see what you're listening to, like watching a sub with good excursion oscillate. I had (still have packed away) a Kenwood KMD-D400 in dash minidisc changer that I kept installed long after I was no longer using minidisc just for it's (nearly) full screen Spectrum analyzer. Love this gadget for that price.

[@MacNifty]

This is one item I don't understand we are lacking with newer equipment more capable more precise and lights and displays wayy cheaper today yet they leave things like this out today. That is a really nice analyizer. Reminds me of the one that was on my 1990 JVC premiere shelf system when auto tape scan / rewind and flip took off. The vacuum lit display reminds me of my mini arcade stand up Boxing game from early early 80's.

[@dondmon96]

I had a 1996 regular cab Dodge Dakota Sport with the short bed. I put 4 Kicker 15s in the bed ported through to the cab with an RV weather boot. We took the cup holders out and put in a Kenwood KGC-7043 single din graphic eq and I loved it! It not only gave HUGE adjustments to the sound but there was a knob on the front of it that had gain controls for my Subs and my high range amps which offered endless setups for your music!! I loved it and wished I never had to sell that damn truck......

[@PhiMobileSounds]

Need the schematics on. Obviously, you can wire in a 12 to 5 Volt converter and I am sure you can solder on RCA connections to the back. Make a quick connect and you are in business. Looks like a quick little upgrade. My only concerns are the brightness and ability to customize the color. This thing in blue would be dope!

[@Djmambo77]

Old school eq's are crazy expensive now wooo!

[@303nitzubishi4]

SO cool! I never knew there were DIN size units like this available. I used to stare at the spectrum analyzer in my Aiwa bookshelf stereo back in the 90s during certain songs. Had a Sony head unit in the early 2000s that had a configurable display that thing was cool too, but there is no substitute for a VF display. This is going on the Amazon wish list stat. Thanks big D another great production

[@wal]

Man I remember going to the electronics stores and drooling over the coolness of those mini systems with the spectrum analyzers and “hyper bass” output. Fun times

[@mytruckinlifeace4047]

Pretty cool but the way the inputs are on the side would make it very challenging to install in a din location.

[@wal]

Yeah, need some right angles or figure out how to solder some wires to the board

[@deezematz]

I was thinking the same thing. Some 90 degree angle ones should work. As long as it doesn't got the mounting hardware. I would def like to get one of these. Hey wiz was there music coming from the unit itself? Or just your speakers.

[@merlijn5467]

Thats why there are soldering connections on the back, you can solder wires directly to the back instead of plugging in the 3.5mm

[@TomMusick]

he used a Y connector coming out of the source. one side went to the display and the other provided a signal to the speaker.

[@ManofCulture]

I think that solder pad on the board near the audio jack is connected, you can probably solder some wire or connector there.

[@josea.garcia3994]

Great video BIG D!!!! 👍👍👍 That unit looks very similar to the Pioneer DEQ-7600 digital processer in which I recently brought on Ebay for $545.00 by having the highest winning bid!!! A lot of people don't know that those old school analyzer spectrum processers still go for a lot of money on Ebay!!!! In most cases they go for a lot more than the original price that they cost when they first came out in the early 90"s!!!!! They are a little hard to find that's why they cost so much!!!! I'm still trying to get my hands on a Pioneer DEQ-9200 digital Processer in mint condition for a reasonable price but I haven't had any luck!!! The one that I did find on EBay they are asking for $1000.00 for it brand new!!!! Sounds crazy doesn't it???

[@wal]

I know bro and I don’t think many people care too much about the EQ or crossover functions, just want something visually stimulating 🤗

Thanks brother. I appreciate the feedback

[@MacNifty]

A project I have drawn out and components priced and all that but haven't actually built it yet.... the Wall sized 8 ft tall by 12 feet wide huge spectrum analyzer. With super resolution better than the resolution for a recording studio mix console meter bridge. Minimum 50 segments using large square style LED's or even somehow with fiber optic light emitting from the glass / plastic fiber style single LED engine light emitting fibers which I found fiber as large as 14mm diameter. Channel the fiber tubes through your base board backing that would mount to the wall, have the fiber come up a hole and over the board and down in a hole like sewing. This way would be the most complicated and pricey build so my thoughts are simple with just the larger button sized square LED's or even push buttons round or square and just 50 segments for 50 levels of one band in the bandwidth / spectrum of the audio and double or triple that same segment if it's not meeting up with the larger scale trying to achieve. I think it would be bad ass to have a full wall sized spectrum analyzer. One that is also truly just as accurate or actually more than twice as accurate as these single din ones. For me with BIG SOUND I also like BIG DISPLAY that is not just stagnant but moving to the music as well and if it's a wall sized meter bridge that's something serious for those who produce and mix as well. Would make awesome for all the live competitions and even stage backdrops for performers / acts. Slap it on the side of a van like those vans and trucks that haul panes of glass. Mount that huge spectrum analyzer VU meter to anything once built and provide the power and audio signal.

How'd your experience with this unit go, in your home setup, and in your vehicle?

[@AlexGeForceASR]

Could you address these questions to the manufacturer AK2515_VFD ? 1. Do you plan to release new HW versions of RTA with the use of a large VFD display in 1/3, 1/6, 1/12 octave with a precise indication of the level of frequency, calibrated in dB, no AGC function, with good accurate ADC, fast CPU, grid frequency: 20,25,32,40,50,64 Hz---KHz 12,14,16,18,20,22 ? 2. would like to have an accurate RTA device, the direction in which it would be possible to believe and not conventional meter toy. 3. Is it possible in this version AK2515_VFD to disable AGC? AGC strongly affects the measurement accuracy of signals, and at different frequencies has a different effect. For example, if there are high levels in the midrange or lowrange of a signal, then the AGC turns on and the lowrange of 8,12,16 KHz becomes lower than the actual signal level. The range of 12, 16 KHz is practically not displayed! Why?

[@wal]

You just did 😬👍

[@meademorgan6614]

What you are looking for and what you want it to do, takes it way out of the $50 price range. Get a grip, this is more or less just a cool flashing light that resembles a spectrum analyzer. Not a real spectrum analyzer. If you actually know what you want it to do, ( and it seems that you do) and you have some pretty specific things you want it to do or not do. Then you already know that a $50 Amazon or eBay spectrum analyzer is not what you want.

[@AlexGeForceASR]

And I agree to pay more. Moreover, I understand well that devices with the required characteristics will not cost $ 50. But let them do it. I'm willing. But there's nothing, nobody does anything. The old devices that are sold on Ebay, I'm not interested because I already have and Samson D1500 and Alesis D230Q, but they are bulky and they can not be built into the device. And from new there is only EVOR04, but it does not use VFD. So I ask, what would this VFD this amazing bulb has developed first-class spectroanalyzer. I'm willing!

[@McOG]

Alex please let me buy your D1500 or D2300Q for a reasonable price!

[@SmashCatRandom]

@@AlexGeForceASR You can just make one - I've made several, both using FFT, and also analogue band pass filters to get the exact frequency bands I wanted. The electronics are not that complicated, honestly - just a lot more components for the analogue version, obviously. If you wanted to use this VFD with your own electronics, you should be able to de-solder the controller PCB and add your own. As said though, you're looking at a lot more than $50 for a custom job. They will likely never make them, as there is no market for anything more than the nice looking audio analyzer they have here. 25 bands is pretty good, to be honest...
