Basic electrical questions.
Cellphones and cordless phones emit far higher frequencies than the frequency components of the digital hash, other component-induced noise, and power line noise that we have been speaking of. I believe cellphones operate in the range of 800 to 19... 
How to go from RCA to XLR?
Rww -- yes, but they still could have provided balanced xlr inputs for each stereo channel, and then fed those inputs into a pair of differential receivers with single-ended outputs. The single-ended outputs could then have been fed into the same ... 
Basic electrical questions.
From an electical engineering perspective, separate dedicated circuits all connected to the same subpanel would all be in parallel with each other. This means that any spurious artifacts from a component fed back into its dedicated circuit would b... 
CD player connected directly to Amplifier?
If the player was made to drive a power amp directly, not all are, then it should give the best sound in that mode. If it sounds better with a tube line stage then: 1, the output stage of the CD player was not of good quality or 2, you like the eu... 
How to Bypass electrolytic caps
I have no knowledge of what Spectral has been doing in recent years, but I recall back in the 1980's that their designs tended to be of the "dc to light" school, meaning ultra-wide bandwidth. If your amp is like that, it would mean that it would l... 
How to go from RCA to XLR?
MBL whom offers some of their most costly designs as either stereo single or a mono pair that simply uses the XLR input to make them balanced mono only. Rww -- I took a look at the MBL 9007 via the link you provided. Yes, it pretty obviously is de... 
How to go from RCA to XLR?
Rww -- I'm not certain I understand your question, but I think you are asking why shouldn't all monoblock amps, at least the better ones that have balanced topologies, be designed as bridged amps. I'm probably not the best person to give you a com... 
Basic electrical questions.
Jea48 -- That was an excellent paper; thanks!However, it does not really address my question, which as you appear to realize was about having MULTIPLE dedicated lines powering different parts of the same audio system. The author describes his own ... 
How to Bypass electrolytic caps
Bypassing in this case means simply wiring the film caps in parallel with the electrolytics. Connect one end of a film cap to one terminal of an electrolytic, and the other end of the film cap to the other terminal of the electrolytic. When I say ... 
How to go from RCA to XLR?
Hi Rwwear,First, I would not assume that the monoblock amps are designed internally as bridged stereo amps, unless you know that to be true for the specific model.But in order to answer your question, let's assume they are. I'm pretty certain that... 
Basic electrical questions.
Can someone offer either a technical explanation, or at least some persuasive anecdotal evidence, to explain the claim that running multiple dedicated lines to the different components of a single system is beneficial. As I indicated in my earlier... 
How to go from RCA to XLR?
Atmasphere, isn't losing 6db of gain the same as losing half the output of the amp or more?No. That's the basic point that both Atmasphere and I were making, which the person at Aragon apparently doesn't understand. Losing 6db of gain just means t... 
How to go from RCA to XLR?
With designs that I am familiar with, feeding a balanced differential amplifier input with a single-ended signal will only mean that you have to turn the volume control on the preamp up a bit higher, by 6 db. It will not affect the maximum power o... 
Speaker Packing?
The one time I used Yellow Freight, about 15 years ago to deliver a large antique radio, they were only equipped to offload to receiving docks, and not to lower items to the ground on a lift at the rear of the truck. They told me this in advance, ... 
2-way vs. 3-way
As is usually the case, there are tradeoffs a designer makes and implementation is often more important than the specific design type.Well said!I'll just add that the fact that the low frequency driver in the 2-way speaker has to handle frequencie...
