| What's the deal with coloring CD's and/or tray mechanism Geoffkait, pure matte black has 100% absorption of all colors. Other colors are used only to reflect only one color. Targets for infrared, for counting number of pulses in rotational speed measurements, are usually gold/matte black (including one ... | |
| What's the deal with coloring CD's and/or tray mechanism Black absorbs all wavelengths. Special infrared sinking paints, used by military, are all black matte. Cheap version, often used, is Krylon 1602. You can easily test it with infrared led (remote control etc) and cellphone (since they show infrared... | |
| What's the deal with coloring CD's and/or tray mechanism Even infrared is absorbed best by the black paint. | |
| What's the deal with coloring CD's and/or tray mechanism geoffkait, black would still absorb red light better than green. Green makes sense if you want to absorb red light ONLY. | |
| What's the deal with coloring CD's and/or tray mechanism If edge supposed to reflect infrared then it should be gold marker, but if it supposed to kill reflections it should be black. Green doesn't make sense. | |
| Apple AirPort Extreme & the Apple Airport Express Firmware Upgrades are Available Done (AE), Thank you hgeifman. | |
| Best DIY silver solder? I crimped and then soldered heating wire first to avoid thermal expansion of the connector. That way it keeps direct oxygen free connection and it is strong. I used WBT solder but it might not make much difference since the solder is only 4% sil... | |
| What transport should I get? RAID 2 is stripping - not very secure and not the backup at all. You need separate HD for plain backup. I use two - second at my work in the case of fire theft etc. I feel that it is more secure than CDs (that can be stolen, lost in fire etc.)I do... | |
| Cd Ripping - is it better to use inbuilt CD drive of laptop or use an external Cd drive Get good program like EAC. I use (free) XLD on the Mac. Program can go to given sector multiple times until you'll get proper checksum (I set my XLD to 200 attempts max). You are extracting data. What is stored on your HD is data and not the m... | |
| Class D Technology AFAIK, class C is a poor choice for audio (better for FM transmitter). | |
| Warm-up time for amps and preamps It is simply drying out of electrolyte. Every 10 degrees Celsius temperature increase cuts capacitor life by half. Presence of voltage on capacitor is beneficial since it is rebuilding dielectric layer (aluminum oxide). Without voltage electrol... | |
| Class D Technology I'm not sure what NuForce are doing. It is possible that they adjust supply voltage to signal level, but that would only mean much lower noise (than for instance Icepower) at low signal levels. Noise level at max loudness would be the same as f... | |
| Class D Technology You might damage membrane from overheating, but most likely not from 500kHz switching frequency. As for switching frequency level following signal level - your understanding of class D output is poor. Amount of switching noise is constant independ... | |
| Class D Technology Switched voltage 50-80V represent the highest output voltage. They show switching noise riding on a very small signal. This signal of 1V peak represents 63mW of the root frequnecy + harmonics on the 8 ohm speaker. | |
| Class D Technology Stereophile test shows about 0.5Vp-p - that is about 1% since switched voltage is in order of 50-80V. It comes from the fact that output filter is 2-pole making it -40dB/decade while switching frequency is about decade above filters cutoff fr... |
