hi guys. after problems with a previous amp. I bought a several more amps to try.
one was a tda7492. my question is, what or how do I use the btl mode as it states
Maximum power:50W*2/8 Ohm Mono BTL power 100W
cheers

I have found a description by using Google.
This seems correct.

Features:
With 4 model GAIN parts, can auto work on different voltage
The use of high-speed SMT placement machine, over temperature reflow, the performance is very stable
Comes with super output short-circuit and over-temperature overload and prevent the impact of the switch machine
Specification:
Power supply: Single-voltage 10-26V DC
Maximum power: 2x50W / 8 Ohms
Mono BTL power: 100W / 4 Ohms
Size: 71 x 60 x 20 mm
Note:
When the speaker impedance is 4 ohms, the operating voltage must be less than 18V;
When the speaker impedance is 6 ohms, the operating voltage can not exceed 24V;
When the speaker impedance is 8 ohms, the working voltage can not exceed 26V.
The power not to reverse the polarity.
cheers guys. so in theory looking at the diagram I would say tie the speaker + to the right side terminal and the speaker - to the left side terminal. or am I wrong

Oh..Yes you are right......sorry my fault. Wrong Attachment.
Sorry

In pic i can see nothing. Diagram....? Can't See it
I found some pics from the other side of the PCB. In the middle there is the Power Connection. Vcc and Gnd
Left and right are the Speaker Connectors. Plus + to plus +....and Minus - to minus-
correct
@jabie5
connect one Loudspeaker to one of the channel (e.g. R+ and R-)and put a Resistor with about 8Ohms and 5 Watt to the other channel.

Power supply: Single-voltage 10-26V DC
Maximum power: 2x50W / 8 Ohms
Mono BTL power: 100W / 4 Ohms

ok chermann. please excuse my ignorance but what will that do. also see specs above, this is why I thought is was mono aswell

sorry but it si not possible...read this...
its written by the board seller....but not from the chip specification
BTL Bridge?

This is seller specifications, false.
Read ST specifications, it's 2x50W, so you can use one channel but it cannot exceed 50W.
Hi,
about this amp board, i have it and i read the same specifications,
2x50W @ 8Ω
BTL : 100W @ 4Ω
Should not it be the opposite ??
2x50W @ 4Ω
bridge : 100W @ 8Ω
or i don't get the bridge...which is possible too
🙂

From the picture I would say that amp is already running in BTL mode ... the four output coils for two speaker connectors is a dead giveaway.
What you've got there is a nice little stereo amplifier ... hook it up and enjoy it.
The specs you showed appear to be gibberish, posted to impress you, not represent the product. Keep in mind that this stuff gets sold in pallet quantities and is often put online by people who wouldn't know an amplifier from a watermelon.
