Foxconn wants to replace 4 million of its workers with robots in China. The wages there have quintupled in the last few years and it is becoming cheaper to do it with robots in China. The robot revolution happened already, that's why there are no jobs and companies are showing profits despite high unemployment. Welcome to the new economic paradigm.

you can tell the difference, but you would have already have had to spend a bunch of dough on tuning the room and putting in very good speakers, and tuning them to the room... and of course for the very fine detail, you would have had to spend most of your life wearing earplugs. But there is a difference. also not all microphones need power. most use an induction based transducer to create a very small ac voltage (-60ish dB), which is then bumped up by the mic preamp, depending on the device to -10 or +4 dB. Condenser mics need power to charge the plates, tube mics also need power... and there is at least one mic that I know of which has a dynamic element but has active electronics in it to tweak the frequency response and requires phantom power.

At some point, the length of cable will reach a point where the capacitance will start to kill the low end of your frequency spectrum... Crosstalk on balanced, twisted pair lines is typically very low. It is the whole point of twisted pair... The transceivers at each end use some form of common mode rejection to kill most of whatever the lines pick up in interference. the higher the number of twists per unit of length, the better it will be at rejecting noise and crosstalk.

Comment Its a biofuel... (Score 1) 468

The CO2 released from brewing or baking, not counting the fossil fuels used to fertilize, harvest and process the grain, have a net zero effect because the grain harvested the Carbon from the atmosphere. Think of it as a biofuel, Ethanol to be precise.
