Hi Hadi,

4 PIN connector is BAL IN and it is not used for bridge connection.

another one near +75v is for heat sink to ground (10 ohm SMD & 1nF/100V)

use 1mm (mica/silica or any heat conductive & insulator) space between MOSFET and Heatsink to reduce EMI.

ETD29 1mm gap all. for 250KHz fsw L= (50uH or 70uH)C= 1.5uF
winding 36T 0.5mm x2 SWG wire or 40T 0.5mm x2 SWG wire

Regards
MANOJ

i do not underestand what are you say.
please say it more clear
thanks
hi hadi,

sorry!!! my mistake for UN BAL input (cold (-)) joined to GND. Hot (+) and GND used for input {you will get signal if connect reverse ie. cold & GND no problem}

can you please share part list?
how can i underestand my source is un balance or balance?
i want conect your amp to my car cd player
may car cd player model is pioneer 7150
it is balance or not?
if i have a balance source how can i wireing?
if i have a unbalance source how can i wireing?
i dont know what you said about balance.
i am sorry but i am amator
i am not electronik enginier but i love it and i am new in electronik

Hi Hadi,
Only two components i used SMD(10 Ohm & 2.2MOhm) both you can ignore (optional)
Consumer product always use UN balance mode (in & out).Only professional Product is used balanced mode.their input and out put is set to @1.3v pp signal level (+4dB)."In balanced working, the signal's positive-polarity connection (+, or hot) and negative-polarity connection (-, or cold) are segregated so that the - is no longer combined with the earth, shield, or ground line. Instead, a three-wire connection gives the ground line its own separate identity. The opposite-polarity + and - signal lines may then be said to be balanced, or set equal with respect to the ground. This balance is engineered, not for aesthetic or philosophical reasons, but so that the next input in the chain can be arranged just to look at the difference between the two audio lines. Every proper balanced input operates as a differential circuit, and any unwanted noise, hum, or interference common to both lines is therefore canceled".
your Pioneer 7150 signal output is UN-balanced one.i think you work for a car amp like SUB WOOFER AMP is it???
if ans. is YES then you need a DC to DC converter for my amp AUD600 and SUB filter.
for 300W 2ohm sub speaker for CAR (small room area) square root 300*2 = 25V supply
so you wire up DC to DC +25v -25V 15A one.

Regards
MANOJ

Hi manoj
answer is yes
i creat it for my car
i dont have + - 25 volt 15A DC to DC converter
do you have any idea about converter
i am ready to creat that
i use pt2322 ic for sub filter and micro AVR atmega64 for control it
(that project is in progres and not complet now)
my sab woofer model is 305c from pioneer company.
thats so good
i have one JBL sub woofer too
it have two magnet 700w 6ohm RMS and it is 12 inch
please help me to creat this things
is AUD600 have short circute protection?
thanks friend

Hi Hadi,
Yes. short circuit / over current and DC protection you can add over temp. protection also.

PT2322 is not a sub filter it is a 6 ch volume controller with tone.are you building a home theater ???
your IC is not bad for home theater. i prefer SPDIF(digital in ) only. they can handle AC3/DTS signal directly.

DC to DC schematic and PCB i will give to you, pls give me little more time

MANOJ

HI my friend
how can i creat over temp protection?
i dont use pereamp or crosse over. i just use PT2322 tone control for 5 chanel amp. what you say? is it enoufe to me or i must use pereamp?
i build it for my own car in home
do you have beter IC like 6 chanell controlabel ecolayser like pioneer car player? it must control by micro controler
can you offer to me a beter IC?
my car player dont have digital exit and i can not use it beacuse i dont have any knowleg about digital sound
sorry for my bad english friends
thanks to all
have a nice day
