2.1 TDA7377 amplifier subwoofer bass three-channel amplifier board Kits(not installed) preamp5532    
2.1 three-channel subwoofer amplifier board, this kit using the STMicroelectronics ST TDA7377 audio amplifier.  The preamp and bass is Texas Instruments TI brand IC NE5532 dual op amp , deep and power sound, clear treble.

 

Satellite channels around the maximum output power 2 * 12W, bass channel maximum power output 1 * 37W.

 

Power parameters:

 

Suitable single supply applications, we recommend using the AC power supply voltage 10-12V, DC supply voltage 12-15V, current 3A will be better .

 

Two potentiometers are bass and overall volume adjustment (Not traditional RC circuit to adjust the bass and treble frequencies, it is   circuit processing done for treble, and bass circuit using a low-pass filter, it does not require an additional Treble potentiometer ), ideal for use in a power supply circuit such as cars, motorcycles, electric cars and multimedia audio conversion (Can connect 12V battery-power )

 

PCB size:length 90MM xWide 50MM

 

Completed Board: 90x72 (with potentiometer handle)
