| Why not underhung voice coil? @audiokinesis Thank you. I can understand it better now. I will try to find out more on Faraday rings. AFAIK they are used to lower influence of magnetic field produced by the coil, but I have no idea what they look like. I cannot find any pi... | |
| Would a wireless volume knob for home theaters be worth it? I cannot imagine big knob on my remote control, so perhaps either small knob or a slider. Buttons on my remote have just right authority/speed and anything else would be just strange (unnecessary). On the other hand I enjoy knob on my DAC/Preamp... | |
| Oscilloscopes - what specs to look for? @jaytor , I noticed that Siglent SDS1202X-E, sold and shipped by Amazon for $359 is identical to LeCroy T3DSO1102 sold for $725.I read that LeCroy relabels Siglent scopes. That would suggest that Siglent is a quality brand. Perhaps one day I wil... | |
| Oscilloscopes - what specs to look for? eyrepm, As Eric said 20MHz is an overkill for audio, but I would buy scope for any possible future adventure in electronics. The basic decision is how much you’re willing to pay. You can buy unknown brand for 30% of the established brand. What you... | |
| Group Challenge - Home lighting, who is in? Erik, perhaps later hour would be better? I know that radio stations have to reduce output power at night, per FCC regulation (better propagation at night), around 6PM. It can be even 7PM or 8PM, taking into consideration time zones and daylight... | |
| Coiling excess Speaker cable, is this a problem? Thank you Al. I just tried to explain why, knowing it is against common belief. | |
| Coiling excess Speaker cable, is this a problem? Inductance of a single straight wire is already reduced in the cable by bringing return wire close (cancelling magnetic fields). Twisting wires in the cable together reduces inductance even further. Coiling speaker cable will do very little to c... | |
| Do speaker enclosures need furniture polish or oil? Spraying Pledge Furniture (wax) on my black gloss piano finish speakers helped to reduce fingerprint problem. | |
| Coiling excess Speaker cable, is this a problem? Coiling would have negative effect for single wire, by adding inductance. Coiling cable is different - it creates common mode choke that has inductance only for common mode signals. For normal mode (differential) signals current in both conducto... | |
| Measure power output without oscilloscope +1 auxinput | |
| Measure power output without oscilloscope Power can be either peak or average. Relationship between them depends on the shape of the signal. For sinewaves average is a half of the peak power. Knowing peak power (peak voltage squared over speaker impedance) will let you calculate average p... | |
| Future of cables! Bigkidz, AFAIK toroidal transformers have very little magnetic flux leakage and perhaps are quieter under normal conditions, but lack of core gap makes them more sensitive to DC in mains, that can produce noise or even saturation. | |
| i'm having a problem with digital brick wall mastering It doesn't have to be compressed to sound distorted. Brick wall filtering might affect sound negatively but not by compressing the sound. | |
| Future of cables! Knot would introduce inductance for common mode signal and no inductance for normal mode (common mode choke), but I doubt that one turn would make any difference. I would rather put as many turns as possible on large toroidal ferrite core (with ... | |
| i'm having a problem with digital brick wall mastering Delay should not make any difference unless filter does something else to reduce peaks. At this point we don't know what this filter does, but if it works then use it. |
