(Is it allowed to advertise here? I have completely run out of money. :cannotbe: )
It is a dual mono 3 level Class D power amp with 50 Hz toroidal transformators. Has simmetrical XLR inputs, it produces 1500 W unclipped sinus power at 2,66 load impedance.
Amp:
full bridge, 8 pcs of FDP2552 in each chanel (150V 36mOhm), seperate common mode and differential mode output filter chokes (cold operation), overcurrent sensing depending on chip temperature (approx. 90 A at cold FETs, 60 A at 100 celsius chip), auto-reset with ~1s period. Max output voltage: Vdd-2V.
Bandwidth: 15Hz-30kHz (+0,5/-3dB), S/N aprox. 110 dB (based on hearing tests), distortion: tbd. Effective carrier freq: 370 kHz. Residual carrier: ~300 mVeff at no drive, ~1,5V at half drive.
Supply:
soft-start, 1 ohm primer impedance trafo with 2*46VAC (128VDC) output, summa 19000 uF 200 V Nippon Chemicon elkos.
+ small signal supplies stabilised, power on sequence ensured by logic.

Did you make distortion analisys and load test? How much is the phase shift and what is the frequency response? What is the switching frequency?
Thanks,
