| RMS Power? Output impedance term can be complex. Perhaps we should rate it in ohms RMS for clarity? :) | |
| RMS Power? imhififan, Thank you for posting. Example of the wrong average power calculation in the second article is very interesting. Using averaged values of voltage and current produced error of 50%. It is very common error. People who design test and... | |
| RMS Power? Thank you roxy54. Almarg is much better in explaining technical merits. I'm just trying to contribute something being grateful for all things I learn here. | |
| RMS Power? Erik, They could say Average Power - power equivalent to power produced by DC voltage of 0.707Vp.There are no two different power values - average and rms as it is with voltage. There is only one power - Average Power.I’m pretty sure that when you... | |
| RMS Power? Wiliewonka - whoever wrote this doesn’t understand it. There is no such thing as rms power. There is only one power that produces heat and it is average power. He says that in his opinion it should be integral over time period of the v(t)*i(t) , i... | |
| RMS Power? That’s true, but it is called average Power in every engineering textbook. Unit of watt already signifies power convertible to heat - a "real" power.Pavg = 0.5PpeakTaking RMS of power curve would bring different, totally irrelevant result.With sin... | |
| RMS Power? Nobody interested? Really? | |
| Who is this cello virtuoso? Dying to find out! Gautier Capuçon You can also see him here:http://www.thestrad.com/queen-elisabeth-music-competition-2017-announces-cello-jury/ | |
| Computer, CD transport or Network Player? I prefer to transfer (WiFi) data instead of music. Data does not contain timing thus computer itself (speed, playback program etc) is not important. It can be done using WiFi, Ethernet or Asynchronous USB. When you connect transport to a DAC t... | |
| Seems like any equipment in a metal case is protected from rfi from Wikipedia:Mu-metal objects require heat treatment after they are in final form—annealing in a magnetic field in hydrogen atmosphere, which increases the magnetic permeability about 40 times.[4] The annealing alters the material's crystal stru... | |
| Speaker phase observation and question? chewie70, My speakers are factory wired inverted by default (woofer wise - tested with battery). This default inverted phase gives me more bass (and fuller nicer sound) while opposite phase brings more treble/mids. My amp and the source (DAC) are... | |
| Harvard newspaper article on Analog vs. Digital teo_audio He is not talking about digital vs. analog in general but about particular difference - the lack of noise in digital. I'm not sure if it is a tape hiss or surface noise but, according to him, it suppose to improve reception of music. ... | |
| Harvard newspaper article on Analog vs. Digital Well, he has whole chapter on surface noise. Ambient noise in the recording will be the same for digital and analog. Same goes for microphone noise. | |
| Harvard newspaper article on Analog vs. Digital Matter of taste. Surface noise on vinyl is not for me. I'm not sure how it makes performance more natural since there is no surface noise at the live performance. | |
| Surge protection for amps? I use Furman Elite 20PFi that have very tight non-sacrificial under/over voltage protection. In addition I have whole house surge protector at the panel. |
