| 3 three channel system, anyone? Magfan...There were two basic approaches to early multichannel...matrixing with many variations but most notably SQ, and the discrete system you mention. Information for the rear channels was carried by FM modulation of a carrier between 20 and 40... | |
| 3 three channel system, anyone? Magfan...What you did was basically the "Dynaco" setup, also attributed to Hafler. The Dynaco setup also included a Y-connected center front, which increased the load impedance of the front speakers so as to compensate for the series-connected rea... | |
| 3 three channel system, anyone? Stanwal...If you use a simple Y interconnect you have shorted the Left and Right together. ALL channels will be Left plus Right... in other words Mono. To mix Left and Right so as to get a center signal without screwing up the Left and Right you m... | |
| bi-amping and effect on cross over Bombaywalla...An interesting observation. Of course the inductor and capacitor values are determined by the desired crossover frequency, not any consideration of overall inductance. This can't be a real-world problem because so many people are usi... | |
| bi-amping and effect on cross over If you just use separate power amps for input to the high and low sections of the internal crossover (do not use a line level crossover) the two amps will output identical signals, so the crossover won't know the difference from using one amp. Tru... | |
| Turntable Speed Using Strobe 33.3 The frequency of line voltage is almost perfectly controlled: it has to be so as to keep all the generators linked up on the grid in sync. Each day, around midnight, there is a brief time when frequency is adjusted so as to get the number of compl... | |
| Classe CDP .3 1.5 skipping non red book CDs What is a "non red book" CD?? | |
| Woofer motion problem. Viridian...A properly designed rumble filter eliminates difference signal between channels, which is vertical groove modulation, and which constitutes most of the problem. Some overall attenuation below 20 Hz, such as provided by some preamps, is ... | |
| Woofer motion problem. Macd...It is unlikely to harm the speaker, but it does have a bad effect on the sound. Get a rumble filter. | |
| Magnepan anything new on the horizon? Those little Maggies may sound great, like many small cone-based monitors, but the spatial character of planar speakers will be lost. This may not be evident in the environment of a small demo room. | |
| Switching to analog...AND building a pre-amp? There was a time when Dyna Kits (which later became Dynaco) had the SOA equipment. I built several units. Work slowly, double checking the instructions as you go, and you will do fine. | |
| Converting Power Cords into Speaker Cables? When I biwired my MG1.6 speakers the first time I tried an experiment. Noting that I was using a one ohm tweeter padding resistor, I used thin (cheap) wire (AWG 24 I think) for the tweeter, and got rid of the resistor. The speaker cables were quit... | |
| Audio advancement - why? If we listen to SS amps long enough humans will evolve to prefer odd harmonics :-) | |
| What Printed Magazine do you prefer? AUDIO (long gone). | |
| Audio advancement - why? Solid state technology DOES have an answer to the imperfections of transistors cited by Atmasphere. Digital amps. (You could make a digital amp using tubes, but there would be no point to it). In a digital amp the output devices are full-on or ful... |
