| best network switch configuration for audio +1 erik_squiresThere are high quality SMPS but unfortunately the most of them, especially wall warts, produce a lot of switching noise. It is practically impossible to avoid them (light dimmers etc.) but noise can be filtered out. I use Furman E... | |
| Class D Technology I am not sure where obsession with the switching frequency comes from. It is inaudible while the only other thing that it might cause is filtering network phase shift - that can be beneficial since speaker has much larger positive phase shift at ... | |
| Class D Technology No, learning about class D is not your goal. You placed many negative posts on class D with no single positive one. That is trolling. | |
| Class D Technology In learning about Class D, it appears that after the linear signal is destroyed and turned into a saw tooth wave form, the output filter? tries to put the signal back together...doing an incredible job considering the complexity of this task...but... | |
| best network switch configuration for audio Yes, it is 1's and 0's but they have to be converted at exact time intervals to avoid additional "products" that result in overall noise. In your case Ethernet network transfers data and not music. Music is created when timing (clock) for this d... | |
| Your opinions on how to string 25 ft speaker cables 12 gauge wire has about 340nH/ft inductance. It is 17uH for 2x25ft wire and represents impedance of 2.14 ohm at 20kHz. Bringing wires closer reduces inductance, twisting reduces it further.As for high levels - levels for bass peaks will be in ten... | |
| Your opinions on how to string 25 ft speaker cables Twisted !!! Twisting reduces inductance of the cable and shields the cable from external electric and electromagnetic interference (preventing induced noise entry back to the amp). It is because both wires are exposed evenly to external fields. Tw... | |
| ROI. Where is money better spent? tls49 +1I spent more on the cables since they are a non-perishable item. | |
| To Bi-Wire or use Jumpers? Hard to say. Some speakers respond well to biwiring while with others it is better to spend more money on single cable. I use both since my woofers, midrange and tweeter are all separate. I use shotgun cable and AQ jumpers between midrange and ... | |
| Warm-up time for amps and preamps Properly designed electronics doesn't have components under a lot of stress. There is a lot of industrial and commercial electronics that stays on for decades including home phones, elevator controllers, phone switchboards, cellphone towers etc. ... | |
| What's the deal with coloring CD's and/or tray mechanism As I explained earlier - spilled light would appear as mostly red but it shows as white (no red at all), because all camera sensors can see infrared and filters are not able to filter it completely. If you cannot understand it I cannot help it. Al... | |
| What's the deal with coloring CD's and/or tray mechanism As I said you can see for yourself with a red laser poster how much is reflected off the black tray.nalso, of the black matte tray was actually 100% effective the green pen wouldn’t make any difference.It doesn't, according to many. You are tryin... | |
| 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. |
