OK, friends, now in this video, this trick is in accordance with the theme, how to install the used music box module or mini amplifier, like this, the picture looks like this, OK, how to install it or the module is like this, OK, let's pay attention, OK, there's a battery compartment then There is also a speaker, yes, the pin. Well, for the path to the original battery, we combine it or we add an Elco. Yes, the Elco can use 470 micro farads or 330 micro farads. For the volts, we can use 16 volts or 25 volts. Yes, install it according to the minus like this, friends. So, next you use a USB cable, so prepare the USB cable, we install it according to the Min Plus of the battery used, well, like this, positive to positive and negative to negative. Yes, like this
111111
So, next we use a check, a check or an RCA cable or RCA jack, which is usually used to connect to the input and output, then we combine the negative cable, the ground cable, which is a bit large, that's the ground cable, then the small cable is the input cable, so we ground it. that's why we join this module, friends, to this module, we join the ground to the module used for a music box or mini amplifier, so it's like this
OK, next we test and test whether it can turn on, now we connect it directly to 5 volts, OK? Well for this, basically don't use more than 5 volts, the power supply, just don't use more than 5 volts, it's safe, right? Without R, without this without a diode, and if by chance Do you have one? Or the amplifier already has a 5 volt USB so just plug it into the amplifier like this, it already has 5 volts, just don't use more than 5 volts, it's still safe, then we connect the jack to the amplifier to the active speaker then the RCA jack cable. one small one, well, like this, basically in the demek-tembak, it can bounce around, you know, this is the speaker that we have, yes, we Anukan, it's really like this, so let's skip it first
OK, let's prepare it, let's connect, connect or connect between the cell phone, Bluetooth, cell phone, then there is Bluetooth, this module, we play the music, we play the music, the music is like this, it's connected and it's playing. So, next we just have to look for which part we connect to this RCA jack, don't go to the speaker. Yes, don't go directly to the speaker, so let's join here, yes, this is the speaker, don't go to the speaker, we will take it from the Bluetooth module to the Bluetooth IC. Yes, there are two, one is an amplifier, then this is the Bluetooth part, so we take it directly to the Bluetooth, don't go directly to the speaker. Yes, because the sound will be defective, so the way we do it is just plug it in, plug it into the Bluetooth IC's leg, so we stick it in like this. We look for it. Well, if it makes a sound like this, it sounds. If it can sound, that means it's the output of the output. from this Bluetooth IC, yes, if you already know, let's look for this path that goes to the power IC, yes, this power IC, we look for the path that is a bit loose, friends, yes, if there is no connection, the cable doesn't go anywhere, so we look for the path that comes from the output. This or that IC is a bit loose. Anyway, don't use this speaker because the sound will be over. So, after finding the path that is a bit loose, for the connection, we click like this, we scrape it until the copper is visible. So, next we connect the input from the RCA jack that we installed earlier. Yes, let's connect the ground here, the connection is here, friends, so don't go to the speaker, don't go to the speaker output of this module, the sound will overheat, Dad, usually it will disappear or what, anyway, the sound is defective OK, ready, let's try, friends, yes, let's try. Well, anyway, the main thing is, don't do more than 5 volts because the IC will break. Yes, if you can, 3.7 or 4 volts, 5 volts is also safe, we can do it better. OK, then if it sounds, it means it's successful, friends, so we can use the music box. If the battery has been damaged, we will combine it with some active speakers or assembled speakers. Those that don't have Bluetooth, okay. This is how to connect the Bluetooth music box to the active speaker, then onto the assembled active speaker. Well, like this, it's very easy. If you want a stereo, just add it. 2R 1k yes, we combine 2R and it can be stereo, if this is still mono, because it goes directly to the mp3 module with a cable or one RCA jack, okay, that's all my trick, I hope it's useful, see you next time, wassalamualaikum warahmatullahi wabarakatuh
