| Amplifier Input Impedance John (Jmcgrogan2) & Bombaywalla, see what I meant when I said that "I don't have a good feel for what the inevitable tradeoffs would be." :-)Thanks, Kirk. Good to see you here again.Best regards,-- Al | |
| Bolero:why can't my system reproduce snare well? A further and probably more significant point than the one I just mentioned: Take a look at these graphs, which are presented in this article. The high frequency content of a snare drum hit, relative to the lower frequency content, is much greater... | |
| Bolero:why can't my system reproduce snare well? Great points by Frogman and Lowrider, as might be expected. I would add one other thought, which is that putting all other factors aside the nature of our hearing mechanisms is such that a snare drum will tend to sound at least a little bit "muffl... | |
| advice on dedicated line Jim, thanks for the detailed and nuanced answer. Good stuff!Best regards,-- Al | |
| Preamps, balanced and unbalanced lines out... As Mofi indicated, usually both outputs will be active simultaneously, or they can be made so via menus. However, in a lot of designs the balanced and unbalanced outputs are driven by the same output stage, and in a lot of those cases the RCA outp... | |
| Driving a power amp with an integrated amp? Somewhere in the forum I read that it is not a good thing for the integrated amp??That would be true if the integrated amp had a tube output stage, and output transformers, as that kind of output stage should not be operated without a speaker or e... | |
| Subwoofer connectivity question Should I run leads from my amp to the sub, at the same time as running speaker cables from my amp to my speakers?Yes. The input impedance of the speaker-level inputs of the sub will be very high. Therefore it will present a negligible load to the ... | |
| Subwoofer connectivity question The input impedance of the line-level inputs of most subs is too low to be optimal when driven by a passive preamp such as the Lightspeed. Also, if the sub is not located close to the Lightspeed the capacitance of the interconnect cables that woul... | |
| advice on dedicated line Great reference, Jim (Jea48), as I'd expect from Mr. Whitlock. And all of the sections you referenced make perfect sense to me. Thanks!Amazing that it took until the last few years for an explanation and measured verification to finally be present... | |
| Amplifier Input Impedance 02-11-14: BombaywallaHow come Almarg hasn't spotted this thread as yet?? ;-)02-11-14: Jmcgrogan2Even the great and powerful Al needs a little vacation time every now and then. ;):-). Thanks, guys. No vacation time needed, though, as I'm always on ... | |
| Bolero:why can't my system reproduce snare well? I second the comments about recording technique and quality.Also, to be sure that nothing simple is being overlooked, are you using the 4 ohm taps on the amplifier? If not, that is undoubtedly part of the problem.Also, given that the impedance of ... | |
| Use receiver for power output from integrated amp I didn't ask but I wonder what, then, the purpose of the fixed pre-out connection might be.Most commonly, driving a headphone amplifier, or a tape deck or other type of recorder.Regards,-- Al | |
| advice on dedicated line Minorl, thanks for your comments, most of which I agree with. However, I would respectfully disagree with the following, especially in a situation such as Margot's where the power consumption of the system is not particularly high: I don't buy the... | |
| advice on dedicated line Jim, thanks for chiming in. Margot, Jim (Jea48) is the foremost expert on electrician-type matters on these forums.To answer some of your recent questions:Would it be workable for me to get 6 outlets instead if 4 in case I ever wanted to plug in a... | |
| Use receiver for power output from integrated amp TLS49 is correct, of course. The fixed-level outputs of the integrated amp are most likely configured similarly to how the tape outputs on many older preamps were implemented. Namely, the input signals are routed to the source select switch, and t... |
