Low Frequency Subhoofer Amplifier
Overview
The TPA3116D2 100W Digital amplifier board can be used as a subwoofer power amplifier board, with the NE5532 buffer matching of the front-stage op amp.
Specifications
- Amplifier chip: TPA3116D2
- PCB size: 75X60MM
- Output power: 100W
- Impedance: 8ohm
-
The power connector is a standard 5.5MM power jack, which is the same as most laptop power supplies.
-
Power supply range: DC8-25V
Note:
- The power supply of the board is very important. The higher the voltage, the higher the current, and the greater the output power. If you only have 12V 1A, you can use a 3-4 inch speaker. If you are above 19V 5A, you can use a 8-10 inch speaker
- Normal operation is to connect the external power supply and the power connector of the digital power amplifier first, and then connect the 220V power cord of the external power supply to the mains socket.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!
