| Office partitions as sound panels I'm building twelve 4x8 panels using 2" rigid Johns Manville 817 panels:http://www.jm.com/insulation/performance_materials/products/ci9_800series_spin-glas.pdfLook at the table showing sound absorption coefficient at 125Hz for 1" and 2" thickness.... | |
| Petition: Stop the loudness wars The loudness war is where record labels turn the volume of a recording up to grab the listener’s attention upon first hearingThat's not the only reason for compression. Music is targeted for average inexpensive system (or boombox) that wouldn't be... | |
| No Balanced Circuitry Does it mean that the XLR output are not fully balanced....???"Fully balanced" is a term that applies to amplifier construction and not the input or output. Input can be balanced (in non fully balanced amp) by either Transformer or Instrumentation... | |
| How to ground a shielded interconnect You have to understand how the shield works. Interference can be capacitively or electromagnetically coupled. In first case it is straight forward draining interference to ground. In case of electromagnetic interference lower frequency coupling is... | |
| big screen - two channel system enough for dialog? It should reinforce center (improve imaging) for off center sitting position. | |
| I Take My Music Seriously Grand piano - I played only once because didn't like the feel. | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, Term "Scale" applies to all string instruments. Please read here: http://en.wikipedia.org/wiki/Scale_%28string_instruments%29Upright basses have 10" longer scale than bass guitar. It makes for much higher string tension* resulting in (a... | |
| Why do audiophiles shun feedback in amplifiers? Ralph, My previous speakers had smaller woofers and smaller cabinets but bass extension was 5Hz lower. Bass quality wise it is much better now with more natural attack and decay. It sounds more even, resonating less with the room (same amplifier).... | |
| Why does better power = better sound? Most "cheap" voltage regulators are less than 2.0% regulation like a LM340If I remember correctly LM340 has 0.01% Vout/V line regulation and 0.3% Vout/I of load regulation. Perhaps you had in mind output voltage tolerance that is indeed 2% in the ... | |
| Why do audiophiles shun feedback in amplifiers? Learsfool, Upright bass has better "definition" related to fact that strings are, being long scale, at high tension. Sound of plucked string instrument can be defined by factors like Presence, Projection, Sustain, Separation and Tone. Upright bass... | |
| music drop out--new router In my case Microwave Oven was operating on one of the frequencies. I changed the channel and it helped. Eventually I got 5GHz router (since my Airport Express receives both 2.4/5GHz)and set it to 5GHz. Now it is perfect. 5GHz is not very popular, ... | |
| New level of ridiculousness Two oil businessman discussed new cars drinking beer at the local bar. They decided to go and buy newest Cadillacs. When it came to paying for cars, one reached for the wallet while the other stopped him and said:"Put it back John, you paid for th... | |
| Replace volume pot Marakanetz, I can attempt to help but have to see schematics - at least of this section. I built my first amp (100W tube 2xEL34) when I was about 15. Later when electronics became my profession I lost interest and now prefer buying instead of buil... | |
| Why do audiophiles shun feedback in amplifiers? Atmasphere, It depends how tight is tight. Acoustic bass is the tightest type because of the very longest scale. On the other side of the spectrum is Paul McCartney's Hofner Violin bass that has very short scale and horrible definition. I believe ... | |
| I'd probably lose this bet.... Speakers are pretty benign with nominal 6 ohm dropping to 3.8ohm worst case but have no idea what happens with phase. Part of crossover is in epoxy - cannot tell what values or even what kind it is. Cable on the other hand is pretty strange. It ha... |
