Tekton Double Impacts
lpretiring One of the things that fascinates me about this hobby is how ubiquitous it isHuh? You find high-end audio ubiquitous? Where do you live? In my part of the world, it's very much esoteric. |
charles1dad ... regarding the preamplifier gain issue, 35 db is far too much for virtually any audio system to utilize. You’d literally have no range of the volume control i.e. one click above the 8 o’clock V.C. knob and it’d be too loud even in systems with very inefficient speakers.Sorry, but you are completely mistaken. There is no inherent correlation between the position of a volume control and the actual output of a preamplifier. Different volume controls have varying tapers, and it's the taper that establishes the link between the control's position and the output of the preamplifier. You can design a control's taper to set the output anywhere you like along the control's rotation. |
charles1dad ... My point is that in "practical" terms 35 db is an excessive amount of gain for particularly a preamplifier/line stage.It sure seems to be excessive! What is the supposed advantage of such high gain in a line stage? |
almarg Cleeds, I wouldn’t by any means say that Charles is "completely mistaken." While it is of course true that there are differences in the taper characteristics of various volume controls ...That was the only aspect of his post to which I responded, Al. Many audiophiles cling to the misguided assumption that the actual physical position of a volume control in some way correlates to actual output power. You certainly understand that a volume control that is half-way between full-on and full-off may drive an amp at half-power, quarter-power, or nearly full power, or anything else. There's no way to tell without actually measuring. I don't argue that 35dB seems like very high gain for a line stage preamplifier and it isn't clear to me what, if any benefit, such high gain would offer. |
