Product Description
Home Cinema Audio System BTL DIY Digital Speaker PCB Circuit Board 2X IC 50W Amplifier TDA7492 D Type SMT AMP

TDA7492 Amplifier Board Characteristics:

1, use the patch SMT high-speed SMT machine, high temperature reflow soldering, performance is very stable, not manual welding process can be compared

2, 4 set of gain control (note orders can provide technical support, monolithic changed, if you don't ask how this board gain adjustment to the largest by default)

3, 70 x 57mm ultra small volume can be used to repair, grind the active speakers, improve quality, can also use the combined block into a multichannel amplifier or 2.1 power amplifier, a lot of useful

4 and bring the strong output short circuit and thermal overload protection, and prevent impact switch machine, this is very rare in other 50W amplifier board

The use of high-speed SMT placement machine, over temperature reflow, the performance is very stable 
With 4 model GAIN parts.can auto work on different voltage. 
Comes with super output short-circuit and over-temperature overload and prevent the impact of the switch machine 
Ultra-small 70X57MM 

When the speaker impedance is 4 ohms, the operating voltage must be less than 18V, 
the speaker impedance is 6 ohms, the operating voltage can not exceed 24V, 
the speaker impedance is 8 ohms, the working voltage can not exceed 26V, 
the power not to reverse the polarity. 


Power supply: Single-voltage 10-26V DC 
Maximum power:50W*2/8Ohm 
Mono BTL power 100W / 4 Ohms 

Package Included:
1 x  50W 2X TDA7492 D Class High-Power Digital Amplifier Board AMP Board with Radiator
