I love the citations referenced in the above post, always been a big fan of RLC circuitry, Inductive Coupling, Reflected Impedance and what a few discrete parts can do [1].Nice. However spread spectrum hits 40Mhz using the same copper (my provider who I do not like **&*) and I'm to lazy to...

!!! SPEC IT SO I CAN TEST IT !!! Yeah, Sr. Engineers and Scientists want to replicate the solution before giving any credit to the assertion (hypothesis).BTW I crashed and burned badly with the "good audio transformer" solutions on ebay as the entire genre was yanked as (what I found anyway)...

YIKES!!! Ushers at the bigger church venues (meeting halls) sometimes call this mob control. That would seem to only allow battery power.Battery power is fine for the (executive) conference room and when batteries run low swap in another battery or if there are power outlets around the table...

I had a nice long reply but the machine ate it with a 404. Did not see the little "restore saved content" box, oh well... a few highlights:Assuming a DAW class: Cntl pnl/sounds and audio/audio/sound playback/Default device/UCA202I did not want to drag curves into the thread. Its nice to...

NO and NO. I'm using the Behringer UCA202 from the laptop USB to the phono preamp input on an ancient stereo amp. The drivers are ROMed on the device (XP SP3). MS probably distributes it by default by now. There is absolutely no noise with this setup (admittedly far from perfect as it is...

In public forms we are constrained as to the message we convey.Looking at other meeting room setups might tell you the practice at your locale (facilities and electrical engineering probably let it the laptops float).I know its not the safest practice but I plead guilty to doing the same...

Yep. I don't see the copper rod working unless the surrounding soil has been treated electrolyticly and even then some locations and soil types make actual earth grounding impossible[1]. As far as I know there is no guarantee that there won't be a voltage differential between power utility...

$46 on Amazon, reviews favorable except for recent Dell Studio Series which is reportedly chipped to recognize and use OEM chargers only (HP reportedly does this as well). IMHO they have gone overboard with these models, targeted at video editing and multimedia in general. Sort of like tower...

Anybody try this ???"Universal notebook power adapter - Compatible with models from Dell, Toshiba, Acer, HP, Sony, Fujitsu, Compaq, ASUS & more. For a complete list, visit" antec.com/snp90"And with seven detachable connectors, the SNP90 works with virtually any notebook on the market...

123.5v Across rails, 60V AC Across Switching Power Supply Pin to Wall Ground (No Load Infinite Resistance).**** thing visibly Arc'd when I plugged it in. Having tested 20KV connectors for Corona I'm still respectful of even small arcs as the instantaneous voltage across air in that milli- (or...

!!! HAZARD !!! DVOM measurement Dell Laptop 20V 5A switching supply ground pin to building earth ground 60VAC (USA 110AC more or less).

Sounds Good to Me (No pun intended). But on the flip side Electrical Engineers and Electronic Device Designers see amps, laptops, lighting, power generators, mains, sub-stations, etc. as big white boxes and (being qualified to do so) tend to discriminate between signal ground and power ground...

Good things opto-isolators, isolation transformers and 1:1 isolation amplifiers.I do not have much to say other than I've been annoyed enough to ask a relatively well regarded manufacturer of sound gear to send me some schematics in hopes of finding a solution to this problem.So after...
