In the same boat as you, I have concerns. In many cases, the volume control from an BT device works well with the board default level, but NOT in every case. You do get increased volume if you hit the audio up board button after your device has been set to a satisfactory sound level. After a power off/on cycle, I am not able to determine if the board "remembers" your board button audio level. As for the audio level up/down switch on the board and the BT device, I didn't worry about that issue since the default level
There are several different tones of beeps. When the device is turned on and when a Bluetooth connection is made, the sequence is different.
In the datasheet, I didn't see anything about people mentioning that, so I believe it's not a possibility.

My sound and volume were good, and I was able to sync with it without any problems. Input voltage was not marked on the board, which is 8-volts from my understanding. The connections are labeled so I was able to connect them without difficulty. A 24V system. Furthermore, there are two dip switches that are not functioning Labels are present. The setting picture appeared on the internet when I searched for it. The volume range does not seem to be the same. This setting is 33 by default. It was definitely louder than I wanted to test when it reached 6 db, so I couldn't tell how the high end of the volume changed. The only strange thing I noticed was that the play/pause, back/next buttons seemed to work sometimes and not. I think that depends on what app you're using. It's not sure if that's a problem with the board or just something to do with Bluetooth in general.
In this review I am looking at the TDA7492P Digital Amplifier Board, which is powered by the TDA7492P chip that is a 25W + 25W class D amplifier. I believe that. The old JVC speakers were driven by two 20W 4ohm speakers using this amp. As a result of the board, my speakers have gained new life. Overall, both the sound quality and loudness of the output were excellent. I believe that. I found the setup to be very easy as well. You can pair your device with the board once it has been powered on SANWU Audio is a bluetooth device that connects a cell phone to. If you do that, you can begin using this message board. Besides those buttons, on the board there are also five others "play", "back", "next", "vol+" and "vol-. " To date, I have only used the vol buttons to control the volume, and thus far I haven't run into any issues. I believe that. It would be a good idea to indicate the voltage polarity of the power jack in the product documentation. Despite the fact that center positive power supplies are very popular, I won't plug anything in until I have figured out where the positive and negative are, especially when I am dealing with DC voltage. I did have to check the polarity of the circuit board a bit in order to give myself some peace of mind. The second thing is that there is a noticeable buzzing noise when the board is connected. This is gone as soon as the music begins. I believe that. Due to the low price point of the board, I strongly recommend it to anyone looking to make a DIY Bluetooth speaker out of it.
I pushed two 6 volt batteries into it. 5 1/2" to 4 1/2" When I play the Rockfords with it in my test box, it is loud! There is a small drop in 1amp when using the bench, and the temperature meter records the highest temp when wide open at 108F. It's also sound quality is top notch, so I will be using this on a regular basis Builds with Bluetooth speakers with four-inch or larger woofers go with this board.
These little boys are so cute when they are working. However, I have had five or six of the 10 or 12 that I have ordered go bad after I have installed them completely or die after they have. It is kind of a pain to have to tear the case open, replace the board, and reassemble because they are perfect for what they are, but like I said, they aren't really reliable on quality.
The idea seems to work, but I'm not very happy with the result. When I tried to use it as a cordless speaker to watch online movies while away from home, it made popping and cranking noises that were just too distracting. Every now and then, it makes a loud noise, similar to during commercial breaks. I bought a different brand of amp (AOSHIKE) for a different project and it worked much better. It had a cleaner sound, and it didn't make As well, the volume is not yet high enough to drown out the hiss, so you need to increase the volume. The signal-to-noise ratio is low so the signal is barely heard. I did not have a great impression of the sound quality.
The price was good and the shipping was fast. It sounds good with speakers with a 4 ohm impedance. 8ohm has yet to be tried. It is simple and easy to I was able to pair my tablet with Bluetooth quickly. This note states For my LG Android smartphone to perform a device search, I had to hit the "refresh" button (arrow circle icon). This is a product I will purchase more of.
There are 50W per channel, which brings the total power to 100W. This is NOT a 250W power supply as Despite this, I powered it up and was up and running in no time both with one of those $3 Bluetooth dongles from China and streaming from my PC. It also works with my Samsung Galaxy S5 too. Yes, the browser is old, but it still works. If I have time, I will post more pictures once my project is complete.
It says this product comes with a power supply three times. There is no way to You will not find a power supply included in the kit! Nothing but a waste of time! We will return as soon as possible!.
