Hi there,
I've got some old Beovox CX-50 loudspeakers that I'd like to use in the basement when doing sports.
Since their quality is not that good I thought I'll go for a cheap Class-T Amp.
I tried the Lepai TA2020+ I have in my car and it's almost enough power (although they are rated 50w/6 Ohm).
I thought about a TDA7492, 2x50W but I can't find any with tone control (probably need to increase bass with these small speakers).
Does anyone have a suggestion for me? Alternatives are the "Mohr SV 50" or SMSL SA 50. I need a finished built as I'm a noob
Thanks for your help,
Christoph

(Hot sale high quality) Music Hall TPA3116 2.0 channel stereo digital power amplifier board with Bass+treble adjust-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group
Close as you're going to get my friend.
Mac
Here's another that's on sale at PE. Mac
SMSL Q5 2x50W Amplifier DAC with Optical Coaxial USB Version 2
In general...
- TPA3116 usually sounds better than the TDA7nnn amps. Some boards sound good in OEM state, others "require" modding.
- 2.0 speaker output boards sound better than the 2.1 output boards.
Having written that, someone pointed me at this youtube: -

There is also a TPA3116 version of the board he uses for a few $s more.

I found this one:
Nobsound Bluetooth 4.0 TPA3116 2.1CH Stereo HiFi Amplifier Digital-Endverstärker | eBay
Bluetooth, 12V but 2.1
Edit: here is a 2.0 http://www.ebay.at/itm/New-Bluetoot...987169?hash=item2ee6853ce1:g:MW4AAOSwWnFWA13k
Does anyone know if nobsound is good?

For http://www.amazon.com/Nobsound®-TPA3116-Channel-Digital-Amplifier/dp/B00WTOAC1M
I found this table:
Power range : 8-25V （Can use the laptop power supply）
Power Interface：outer diameter 5MM，inner core 2.1MM
（We recommend 17V-22V，use 12V or below as power supply will have a greater impact on this amplifier power）
Power supply voltage:
12V ------- 8 Ohm speaker / 12W (left channel) + 12W (right channel), 4 ohm speaker / 20W (left channel) + 20W (left channel),
15V ------- 8 ohm / 18 + 18W, 4 ohm / greater than 30 + 30W,
19V ------- 8 ohm / 32 + 32W, 4 ohm / greater than 45 + 45W,
24V ------- 8 ohm / 38 + 38W, 4 ohm / greater than 55 + 55W,
I guess it's probably similar for the other amps? I could then use this one for example in the car where I only need 20w (12v) and the normal, not mini version with a higher power power supply for the 50w beovox speakers

This one seems promising.... Nobsound Bluetooth 4.0 TPA3116 Digital Amplifier HiFi Stereo Integrated amp 100W | eBay
Complete in-a-box solution including power supply.
I haven't listened to it. Shipped from Germany though, so EU consumer laws apply if it's a) crap or b) broken.

I've ordered this one now, for testing:
Wholesale Product Snapshot Product name is 2015 New TPA3116 digital stereo 4.0 Bluetooth amplifier 50w+50w with high bass adjustment Mini Power Amplifier
The knobs seem to be nicer. Let's see how good it is

Here's a link to a YOUTUBE video with a BREEZE AUDIO TPA3116D2 amplifer and Little Bear P-5 Tube Preamp, which inspired me to purchase them for a pair of modified TABAQ using the Tang Band W3-2141 3" driver I'm building for my brother. Have a listen, as I think you will be quite surprised at the wonderful sound.

*Speakers are almost complete, and I can hardly wait to get a test listen, before I take them to my brothers house. DIY'ers always get the first listen!

Finally it arrived
2015 New TPA3116 digital stereo 4.0 Bluetooth amplifier 50w+50w with high bass adjustment Mini Power Amplifier-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group
TPA311 BT4 50w
It's working and sounds not too bad, have to test it in the car though.
This is how it looks like inside:
What do you think? Can anyone familiar with the components tell me if it's worth it?
I'm not an diy audio guy..

I posted thoughts here on a nearly identical board. Was curious if others get noticeable noise using its Bluetooth, esp. during quiet passages.
Don't recommend wasting time trying to fix/improve it as I did, just use as is... Maybe after adding a bit of thermal paste between heatsink & chip if there is none.
BTW don't know if normal car voltages will be so great w/this board, its LM7812 min dropout voltage appears to be 14.5v.

I tried it in the car today - I'm getting some noise if there is no sound/music. And also, if I leave it turned on I get the typical pop sound when turning on the car.
Not sure if it can be solved (with my basic knowledge), I only know those power filters for the audio inputs, not sure how this can be used with a BT amp (on the outputs?).
