INSMA TDA7492P Dual Channel Wireless Bluetooth 4.0 Audio Receiver Digital Amplifier Board with 3.5mm Plug (TDA7492P Chip)

The overall product was good but the Bluetooth signal was horrible. It would cut off even for a change in the phones orientation from 5 meters away. But the sound quality is okay

Thanks Amazon

Good amplifier

I bought this amplifier to install in a DIY ammo can boom box. It is small and compact but puts out more than enough power for two 4" speakers. I was pleasantly surprised at the sound quality. When using the bluetooth feature, there is a faint buzzing or humming noise when there is no music playing, but once the music starts, you can no longer hear the buzzing noise. Also, when the amplifier is powered-on, there is a very brief loud thump. For this reason, combined with the buzzing noise, I deducted one star. Otherwise, I am very happy with this device.I power this amplifier with a 12V 5A gel cell battery, and the battery life is amazing. I take it off the trickle charger and the voltage reads 13.1V. After 8 hours of continuous listening at moderate outdoor volume, the battery never dropped below 12.6V.

It's not the best amp I have used I got this one cause I wanted it fast I ended up replacing it later was not happy with it at all bass mids and the highs just vary hallow and large amount of noise when not playing music

Used to make a boomboxVery loud

Sound is a little low and it crackles if you touch the cable plugged into the 3.5mm even slightly.

Some confusion about this. The 3.5 mm port is AUX in. Works great from my Aiport Express.

Great board to create you own BT speaker system. Plenty of power and response.

Works really well. Built this into a hardwood DIY boombox.

Tiny but powerful. The Bluetooth connects very easily. Built at rocking boombox with it.

Worked for a few months and now it's dead. Bluetooth connects but no sound...

Have at least five products made by this company and none of them have held up. Very disappointed. I guess you get what you pay for, don't go cheap

Great simple unit, poor battery terminals (recommend you connect leads and secure)Had a few speaker terminals , a little hot melt glue, a old plastic box and a DeWalt battery

Excellent for the price. Sound isn't high end but works well

Product works as advertised. Bought the 3.5mm version, which serves as a line in (I am using it for a line in from my PC). Great alternative to a full receiver to drive bookshelf speakers.

Good little amp but it has its issues. The version I received is the Bluetooth plus 3.5mm in. When connected via Bluetooth without audio thing you can hear some weird interference. But during the same with or without an airplane and a cable plugged in To the input, I get very bad interference! To remedy it, I leave the input splitter disconnected. Also, I get a loud pop from the speakers when turning the amp on or off. Also when turning on, the Bluetooth connection tone seems to play at full volume, and it isn't a simple chime either. It's so annoying. But other than that, great Bluetooth range, and a great value for a diy bt speaker.

It took about 5 minutes to hook this device up and it worked perfectly. Good sound. I marked it down because there are no instructions shipped with the unit, but a little internet search resulted in a useful hookup diagram. It's actually pretty intuitive, but I like to have documentation. The other demerit is that it took 30 days to arrive after I ordered it. I get a lot of stuff from China and most items arrive in a week or less. Other vendors offer quicker delivery times.
