Visualizing the Spectrum? AK Technologies AK2515 Audio Spectrum Analyzer

[@profewiase]

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

[@santoslaguna58]

[@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......

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.

May require a little work to get it working in the car, but I know you guys are resourceful. Post some pics or email me some when you get them installed BigDWiz (at) gmail dot com

[@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!

Thank you for another outstanding video!!! I so miss the EQ analyzers from the 80s and this is freaking cool I love it I am definitely going to purchase one or two appreciate the videos very much brother.

[@ColettaHughes]

Looks nice, but that's not an EQ it's a spectrum analyzer. However, if it's somewhat acurite, it would be nice with an old school EQ so you could see your adjustment like on an Alpine.

[@clearme2]

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 .👍🏻

[@rogergreen9861]

I had been craving some spectrum toy in the practice sessions and had not happened on this gem until your review. Cheers, mate. Just bought one.

[@NotWatching666999]

That's awesome! I use to have a Kenwood double din where the second unit was a 7 band display and loved it. The only reason I bought my Panasonic and Awai Decks were the spectrum analyzer. If only I could find a way to make it look factory in my car.

I know which one you're talking about :)

[@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.

[@2011joser]

Great video Big D. Good to see variety related to car audio. I was inspired to build my bench top power supply by your video a while back. This thing is cool, now I just need to find a way to use it so I can buy one.

[@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.

Cool man. This one will need a 12V to 5V USB adapter and either RCA to 3.5mm adapter or some soldering skills to add RCA’s to pads on the unit. But yeah, it’s super cool looking 👌

[@hammerhome7879]

Personally I think that the manufacture would be wise to market this with a din size frame around it , to appear as something from Alpine or other major manufactures. Also mount the function buttons on the front , built into the bottom or sides of the screen.

[@BenjaminEsposti]

3:28 I bet that device has either a small supercapacitor or a backup battery (rechargeable?) to power something called a "Real Time Clock" ... basically, it is a dedicated circuit to keep time, and is built to be able to run off of a battery for years. (Literally with microwatts of consumption.) Also, that's good that it had the correct time, as some cheap RTC's are notorious for being inaccurate (like, loosing a few minutes per month!), even on some PCs/computers from well-known manufacturers. P.S. $40 for a device with a large VFD display like that is actually a bargain! Try buying a VFD like that from an electronics distributor like Digikey ... You'll be paying about $100 for a display that size ... ahh, the wonders of China!!!
