LM4780 GC's- I'm using them parallelled and the sound is pretty good, but just a bit too strident in the top end- I'm getting a >100Khz bandwidth which might explain it.
The data sheets say to use Cc approx 220pf between the In+ and In - pins (15,16 and 21,22), but that just made it ring above 100KHz, so i connected the 220pf caps between the In+ pins and earth. That decreased the bandwidth to about 80Khz and it sounds better to my ears. Is that the correct way to do it? I wouldn't mind decreasing the bandwidth a bit more ,470pF should do the job. I'd appreciate your advice, expertise if you could please. |
