| Impdence Question Duke - I like your example wit divided coil, but I think that the difference is that EMF of both coils reacts with the speaker membrane motion while in case of two separate speakers it doesn't - even if they are driven with the same back EMF (same... | |
| Impdence Question System doesn't like long links and shortens them. The way I see it speakers is controlled when EMF generated by the speaker is shorted. Just take speaker and move/press its membrane - it moves freely. Now try to repeat it with speaker shorted by w... | |
| Impdence Question Sorry - link got shortened in my last post - here it is again:http://manuals.harman.com/JBL/CAR/Owner's%20Manual/15515%20GT4%20Man_ENG.pdf | |
| Impdence Question Audiokinesis - JBL in users manual for GT4 car subwoofer system states:"We recommend that you avoid connecting separate woofers inseries. The amplifier-damping factor (the amplifiers ability to control the motion of the wooferis expressed as a rati... | |
| Impdence Question "The only practical way to increase driver impedance is to either wire two drivers in series or use a transformer."Do not connect speakers in series because it will lower damping by amplifier (speakers isolate each other from the amp) - poor bass ... | |
| 3 meter interconnect? Kenneth - There is always a loss of quality, proportional to distance, no matter what type of cable. How pronounced it is depends on the quality of the cable and your perception. I bought my cable short 0.5m "just in case" and never tried 3m one. ... | |
| hd broadcast Fred - HD conversion next year applies only to over the air broadcast. Cable and satelite providers can do whatever they want. | |
| Digital XLR vs. Analog XLR - Balanced Cables Ckoffend - Maybe whole thing it is too technical but it is important to understand that 192kHz signal is really transmitted at 25MHz. Maybe part of article below will explain better why digital cables exist. I don't want to engage more in discussi... | |
| Digital remastering of CD's Carl109 - I have bad suspicion that the only thing that drives them to create new standard is desire to implement copy protection and raise pricing. SACD has pit modulation technique where watermark of CD is implemented by modulating sizes of each... | |
| Digital XLR vs. Analog XLR - Balanced Cables I do not know what doesn't make sense to you. Frequency of transmitted signal in the cable has nothing to do with transmission line effect no matter what multiplier you put on the top of it. What is important is the highest slew rate appearing. Yo... | |
| Digital XLR vs. Analog XLR - Balanced Cables Whenever an electromagnetic wave encounters a change in impedance some of the signal is transmitted and some is reflected (impedance boundary). Reflected signal creates all sorts of shape distortions making overshoots, oscillations and staircase (... | |
| Should a dac run hot?? Harnellt - I assume you talking about power transformer. Typical failure is caused by overheating and in effect destroying enamel on the wire causing shorted turn. Shorted turn heats up and wire melts interupting current flow. Why you suspect tran... | |
| Digital XLR vs. Analog XLR - Balanced Cables Ckoffend - I would say that most, if not all, digital cables have particular targeted characteristic impedance - in case of audio 75 ohm for unbalanced and 110 ohm for balanced. But just look at typical 75 ohm video coax - it is so much different ... | |
| Digital remastering of CD's Carl109 - HDCD is 16-bit. Bit #16 (LSB) switches dynamic range of the signal represented by only 15 bits. | |
| Digital XLR vs. Analog XLR - Balanced Cables Here is the quote from Stereophile article "A Transport of Delight: CD Transport Jitter""While we're on the subject of the digital interface, I should point out that the engineering for transmitting wide-bandwidth signals was worked out nearly 50 ... |
