![]() ![]() Just spoke to and we were able to come to a resolution. The Shade Room has since revealed on Twitter the situation has been rectified. The Shade Room says issue has been resolved And YOU called ME asking why we don’t post your family! Lie again and I’ll put out the receipts. We are only addressing your comment on negative content we didn’t bring up your daughter. In response to Cardi’s rant at The Shade Room, the blog responded by accusing Cardi of lying. Why not ask her s***, why not ask me on DM? The Shade Room snaps back Wait how can you say that, when have you ever asked me to ever post anything about me? And if that’s true you got my publicist. ![]() All of this but ignore me a couple of days ago when I DM y’all. You can’t show a DM or anything of me asking you that and I’m not dumb to post that call but trust I got it and even on that call never asked y’all that s***. In my experience that although the latter has been known and implemented for nearly 50 years now, the cheap easy fix is what you frequently get even on high priced gear.Cardi went on for while, further down the post she said: If on the other hand the trim is in the feedback loop of an input IC opamp, then the trim can not only prevent clipping but also improve S/N at the same time. If they are after the first stage, then they can optimize S/N but not prevent overload clipping of the input stage. This will prevent clipping, but degrade S/N. Unless you have a circuit then you don't know how the trim input pots are designed. Now this is where the difficult part starts. So if you hear no hiss or noise at your listening position with volume or trim pots set in a sensible range you are OK, as long as you are not getting distortion in the loud passages. Without instruments, which incidentally few invest in, but should, you can only do this by trial and error. Simply it is optimizing signal to noise ratio and avoiding clipping of any input output during playback of any program. So in well written, orchestrated and recorded music there is going to be a vast range of voltage at inputs and outputs throughout playback. ![]() I know in the pop industry they don't know or understand this, but I don't cater or engineer for those idiots. The first thing to remember is that music is, or should be, highly dynamic, with wide dynamic range. In that case: is it better than not using attenuators? Because, isn't sending the signal from preamp as hot as we can (without any distortion of course) the perfect way to increase Signal to Noise ratio?Ĭlick to expand.There is no simple answer to your question in a way and in a way there is. this means my preamp will now need to send 4.48V to drive the amp to full power, right? If, on the amplifier, I'm starting using attenuator nobs : for simplicity let's say I will set them to -6dB. So, as a conclusion : My preamp needs to send 2.24V to drive my amp at full power using balanced inputs which will be easy considering it is able to output as much as 8V. voltage output of the preamp is doubled)" From there we can conclude with a gain of 29dB that we need to send 1.12V from preamp to drive A23 to full power.Īnd I guess for Unbalanced it does translates to 2.24V, given unbalanced sensivity is given "per leg", which correspond to Gene's comment : " THX standard gain level is 29dB utilizing balanced inputs decreases this to 23dB, though naturally the output of the preamp is boosted by 6dB under this scenario (i.e. If A23 is 125W into 8Ω, then max amplifier voltage output is 31.62V. Gain : 29dB with attenuator nobs on "THX" position (attenuators defeated)įirst, it seems Parasound A23 sensivity is not given for full Power, as 28.28V output into 8Ω translates to 99.97W (Parasound A23 is 125W RMS into 8Ω) ![]() Input Sensivity : Balanced 1V for 28.28V output into 8Ω, Unbalanced 1V per leg for 28.28V output into 8Ω Max Output Level : 4V unbalanced, 8V Balanced at 0.06%THDĬontinuous Power Output : 125W RMS x 2, 20Hz-20KHz, 8Ω, 0.06%THD both channels driven Please note: I'm using this article as my main source for maths. I would like to understand if there is room for improvement playing with attenuator nobs on an amplifier versus going the "plug, play, forget" way of life -) I would like to talk about "Gain staging", or "Gain structure" as I'm not sure to understand it fully : ![]()
