2x25W at 4 Ohm TDA7492 Class-D Audio Amplifier Board Only
Does this, or any similar amplifier module you sell, have provisions for some sort of "power up when signal is applied" control option? Either input signal sensing or maybe some sort of "apply [5-12V] here to power up" system.
Not an answer just a further observation: In the ornery of the PCB near the inputs there are two pairs of contact points labeled STBY/GND and MUTE/GND. They're not mentioned in the manual. Could this be what I need - an undocumented feature?

Will this amp run off of a 12v lead acid battery? Thanks.
Not recommended. Requires a DC power supply ranging from 14 to 19 VDC

I'm confused. There seems to be different iterations of the same model. The one in the manual states a volume control board is required, but the one in the picture I see holes to put in potentiometres. Which one do you sell?
J11 on the board specifies a standby mode. I was confused by the previous answer to this question. To activate standby all that is needed is to complete the circuit between Standby and GND, correct?
How would this perform powered by 12 aaa batteries for a total of 18v? What would the lifetime be like?
I'm building a portable boombox and the problem I am running into is finding a battery that can power this. Does anyone know a solution to battery power this amp and the battery not be an acid battery. I was hoping for something like a LiPo battery?
I run this amp great with my 18v drill batteries! You can find these with a charger anywhere.
