I installed it internally in my old car radio pioneer, the sound was of excellent quality.
Yeah I like it too 😊
I recentlyy found a very old cassette tape/cd boom box on the curb and i want to add bluetooth to it. It will be very nostalgic if it works.
Хареса ми аудио кабела ти!
Ръчна оплетка 😁
Браво!
Позна позна ;)
Thanks for the video. 2 points of concern if I may:
the noisy smps 5v power
The metal around the BT module will kill BT RF.
I must confess you are right 👍
Excelente tengo un teatro 4.1 RCA y no tiene Bluetooth le pondre uno por que es un teatro com buena potencia y se me hace un desperdicio tenerlo botado
Gracias excelente video
Thank you 🙏
I did an upgrade based on your video. I used a power supply with USB 2.0 output, which I built into the amplifier (Teufel B200), which is smaller than yours, I didn't have much space, but I managed to pack everything in nicely. The problem is that it plays terribly quietly. I have to turn the volume all the way up to hear the BT sound. What could be causing this?
Are you sure you connected the output from the BT module to input of the amplifier. The BT module is able to give signal to your input of the amp. Then set the amp input where the BT is connected to. Volume from BT can be adjusted through the phone, when you bind it. Something has to be wrong. It has veey loud and clear sound in my setup. Please see report here when you manage to play it as it should be or if you need some further help ☺️
@@FixitEasyDIY Thank you! I connected to the only input this amplifier has - AUX. And just such a problem with the terribly quiet sound. At first I connected the ground wrong but after taking the whole amp apart I managed to do it properly. Technically it works ok, connects to iPhone 12 mini, MacPro6.1 or MacBook Pro 2018 without any problem.
Any humming, hissing noise? Since there is no ground loop isolation or DC filter
Actually there is no problems at all. The sound came up pretty good 😊
How to control bass and treble?
By implementing the module you can use the controllers on the front panel ;)
I tried draining power from the board, but that gave a terrible noise through all inputs.
There must be a way to do it without noise injection. I used a separate power supply. Ugly but working just perfect.
Евала за клипчето човек ,обаче какво направи ти,взе зарядно за телефон на входа му върза 220v ( ac) на изхода излиза около 5v DC и върза модула за него.Обаче ако се налага да се вгражда в авто сд така няма да стане.
В автокасетофонче ще е същата процедура, само че ще трябва едно понижаващо модулче от 12 на 5 волта вместо зарядното ;)
@@FixitEasyDIY именно
Съгласен съм ;)
@@FixitEasyDIY не разбрах от къде взе сигнал за каналите
@@FENIXDJBEATS На модулчето има пинчета с изходи - паралелно на изхода, които е с 3.5 мм жак. Просто ги запоих, за да не слагам и кабел с жак, иначе става и с готово кабелче.
Здравей ! Може ли линк към модулчето в Али Експрес ? Благодаря ти предварително ! :)
Ето цялото видео за това модулче. Мисля, че в описанието на видеото трябва да има линк, но до минута ще го напиша и тук. Поздрави ;)
Ето го точният линк: www.aliexpress.com/item/32961053585.html?spm=a2g0o.order_list.0.0.21ef1802gIerWJ
Благодаря ти много ! :)
Could have tapped 5volt supply in amplifier
I wanted it to be inside the enclosure. Not the best way to do it but it's working just fine 😊
Any advice or sources of info to find out where in my amp I can find and safely tap a 5v power supply? I'm thinking of doing this to my old sony ta1066
Easiest way is on the transformer's primary coil. It will trigger 5v when switch is ON.
@@FixitEasyDIY no..DON'T do this, no way..just DONT
Какво мериш в началото на видеото?
Проверявам на кои крачета кореспондират плюсовете на ляв и десен канал и кое е масата. Оказва се, че масата е отстрани и исках да съм сигурен.
@@FixitEasyDIY Благодаря
@@yanev93 няма грижи. Ако мога да помагам с нещо съм насреща ;)
the audio quality is plain useless in those vhm-314 chips and all the like - has nothing to do with hi-fi. dramatic rolloff at lower frequencies (possibly higher too), cataclysmic distortion, stereo separation is not what it is supposed be in stereo sound, possibly resonant peaks, audio image is completely wrecked to oblivion, hissing/buzzing noise even from clean psu. these are complete waste of money/time. the only positive thing about these is that there is no chinese lady saying "bluu tooot divaice s nauwh khonnekted".
Can you recommend another bt decoder, i almost buy it, glad to see your comment
out of these chinese ones the best one was ZK-PT2 even though it uses a JieLi chip. There's a reason why these things need proper capasitors - and therefore there's an increase in price. @@LFSIDIndonesiaOld
@@voltagetoe thanks for your advice🙏 sadly this thing is not available at my country marketplace😅.
have you tried QCC5125/QCC3034? i picked up the latter and from what i can initially tell it seems pretty solid.
Another silent movie.
Would have been nice to hear what you are doing rather than listening to some crappy music. Anyone not exactly 100% confident in what you are doing won't have a clue. If this video is only for those that know how to do this then what's the point?
I have nothing to say. You are just right. I am still learning how to make decent videos. Sorry for disappointing you 😔.
The instructions are very very clear, it isn't his fault that your average person doesn't understand, i wouldn't recommend dealing with live wires if you don't know anything about electricity in the first place.
To any aspiring hobbyists out there: DO NOT DO IT LIKE THIS!
I have been using it for more than a year and there are no worries.
@@FixitEasyDIY If you ever sell the amplifier please remove your dodgy modifications first.
hi, great video. I wanted to know if there is a module that transmits audio instead of receiving. Thanks
Hi, thank you for your comment. I have seen transmitter modules on AliExpress. I`ve seen double mode working modules also TX and RX. Just pick one of your choice ;) They should be pretty simple and cheap devices in general.
