Possible to add gain control to boostaroo?
"Arny Krueger" wrote in message ... I think this is the first time I've been criticized for posting test results that were unbelievably good! ;-) No criticism at all, if true. I just wonder if your 16 ohm load was disconnected without you knowing. (I originally thought it was just a simple typo) Given what we now know about the boosteroo circuit, I still can't see how you can obtain those figures from that IC into a 16 (or 15) ohm load.

I just wonder if your 16 ohm load was disconnected without you knowing. (I originally thought it was just a simple typo) I could measure a slight drop in output voltage when I hooked the load up. One thing about these digital audio measurements, you can see the difference just about everything makes, even if stunningly trivial. Given what we now know about the boosteroo circuit, I still can't see how you can obtain those figures from that IC into a 16 (or 15) ohm load. I think you underestimate modern IC technology. Besides the proof of the product is the sound quality, right? My Boostaroo is hooked to the PC I'm typing on right now - giving the internal audio interface a little extra oomph for driving Sony 7506s. Stevie Ray sounds great! I run my Boostaroo off a 5 volt power supply salvaged from an old cable modem. I use it all the time for mixing multitrack recordings. Works for me! |

However boost that distortion by another order of magnitude above 0.07%, and there are ways I can nail it in a DBT. 0.7% nonlinear distortion isn't happening below clipping with the Boostaroo. |

However the device spec sheet talks about 10% THD. Yes, a quite common figure used to get the maximum power output, not infer any performance level for distortion below full output. However boost that distortion by another order of magnitude above 0.07%, and there are ways I can nail it in a DBT. 0.7% nonlinear distortion isn't happening below clipping with the Boostaroo. I never said it was. But there is a big difference, spec wise, between 0.0007% and 0.7%. However if you say the figures are correct, then I'm not going to argue any further, since I have yet to measure one. TonyP. |
