t-amp? what izit?
its a type of amp produce by tripath, basically a much refine class-d amp.
there is ta2020, ta2024, ta2022, the 1 i brought in is ta2024, bang per buck you cant beat it
some good reading abt the ta2024
sonic impact T-amp which make this chip really famous!
since most of you guys that ordered will be getitng thier parts by today, let me start off with some of my built 1st
doing it very slowy as this is my 1st built, altho simple but not femiliar with it.
i got 2 boards with me, 1 i will mod as i build the other completely stock wana compare the difference, altho im planing to run active setup with 4 channel.
stuff you need to start for those new to DIY
for 1 board you need
solder and lead ofcos
multimeter if available, else be very carefull with what you are doinglor...
some cable. cat 5e or cat6 are easily available and easy to work with
a housing that you like
on/off switch x1
power supply terminal x1 set (male and female)
rca female x 2 (1 black 1 red)
speaker terminal x 4 (2 black 2 red)
a stereo volume port
some parts are not shown here
pretty straight forward, solder 1 wire to each terminal pin, red goes to +ve and black goes to -ve
the middle pin will be the signal, side pin for ground.
so which is which?
middle pin is ground
right pin is the right pair
left pin is the left pair
left and right channel will share the same ground
when you buy a switch measure for connectivity when you off and on it.
for mine its the middle and top pin
taken from ESP, well im not too sure how it works either , didnt check it out cos im not using it, so here's wat i got form ESP
hmm...same for 2 pot? sifu please advice so i can update, newbie here....
from RCA female to board input im using rs 485 data cable,
i gounded the shiled (connect it directly to 12v -ve)
the rs 485 cable
other then that it is cat6 for all the power supply wiring, and cat5e braided for speaker terminal, wanted cat6 but i dont have much as you can see i remove all the terminal and solder directly.
capacitor power supply are cheapo jalan pasar stuff, 2x 10000uf and farnell 3 x 3,300uf.
in the middle you can see a 40amp relay use in car. i believe those transfer voltage better then the switch alone.
Attached bellow is the evaluation board by tripath, our board follows tht design minus the input coil, most ta2024 amp follow this design
