Anyone has the 125ASX2's designer manual? Ghent from Ghent Audio sent it to me once but I can't seem to find the file or the original email. I can't find it online (only the 50ASX2 can be found).
Thanks
Thanks, but that is the data sheet not the designer's manual
Just a small question: is this simply switching noise? I just connected an oscilloscope to the output of the amp in BTL mode.

Do the math: 1 uS per division, the wavelength period is about 2 divisions, so 2 uS.Just a small question: is this simply switching noise? I just connected an oscilloscope to the output of the amp in BTL mode.

on my ACE125 483 Khz but 2 V ptp so mutch. simply for test i put a L C component at both outputs and ch1 200mv and ch2 300mv ptp.Do the math: 1 uS per division, the wavelength period is about 2 divisions, so 2 uS.
f = 1/T = 1/2 x 10^6 = 500 kHz. Bingo, switching frequency.
I used to go through calibration gear as fast as I could afford it. I've had several CRT Tektronix scopes and my fav CRT O-scope is this.( I've had HP CRTs too and some of them have some pretty nice traces too.) I suppose I could get with the times and think about a digital O-scope but for troubleshooting stuff a CRT is so fast and easy to operate.I love Tektronix scopes.
How do you have Pin1 on the 8 pin signal connector wired? Should be no connection for stereo and tied to ground for BTL.I have two working in btl with the ghent se>btl board.
Now building se stereo version via another board, but cant make it start in stereo.
When swithing the new board, with one of my old ones, it works in the btl cabinet.
Does stereo need buffer to work?
