| Maggies with no Sub: Fantastic surprise Dogmcd and Dave_b...All speakers, cone or panel, experience increasing distortion before their output rolls off. Indeed, distortion components tend to hold up the measured output level as the fundamental, which is what we care about, rolls off. If... | |
| Maggies with no Sub: Fantastic surprise Martykl...I spent quite a few frustrating years searching for the "correct" crossover frequency. Then the light dawned! There is no correct frequency. It depends on the music.I have an electronic crossover which lets me vary the crossover frequenc... | |
| Maggies with no Sub: Fantastic surprise I love my Maggies, and agree that their bass response is most often OK without subwoofer help. Just the same, I have a very elaborate built-in custom 3 channel (fronts) subwoofer system. Three 15" drivers and 3 12" drivers individually driven by s... | |
| Maggies with no Sub: Fantastic surprise If you use a spectrum analyzer you will see that the LF roll off of the Maggie is perfectly smooth...no peaks and dips. This is, supposedly, why Maggie bass sounds so much better than what would be expected from the -3dB specs. Also, as Jallen not... | |
| Riaa curve Chosenhandle...There is only one RIAA phono equalization curve. Before this was agreed to different labels did indeed use their own propietary curves. | |
| Speaker wiring question Don't do it! A "Y" connection will short the two amplifiers outputs together. While preamps are unbothered by this which is a way to get a mono signal (they are short proof) power amps are likely to burn out. | |
| Looking for an excellent outdoor FM antenna The Magnum Dynalab ST-2 is very unobtrusive. It performs OK, but not like my big Yagi on rotator. | |
| BALANCED VS UNBALANCED The output buffer stage and input buffer stage of the "cheap" equipment are unity gain circuits, one of which happens to be wired up for signal inversion. Unity gain circuits are easily implemented with near-zero distortio/noise. | |
| Dbx lps The DBX encoding scheme for LPs provided superb performance and comparable in every way to CDs. DBX, unlike Dolby, refused to license hardware manufacturers to use its patents. Dolby (in the cassette tape field) encouraged hardware manufacturers w... | |
| Disconnect the woofer I am not familiar with other Maggie crossovers, but the MG1.6 crossover, while simple in concept, has features which many external low level X/O lack. High pass is a simple 6dB filter. Low pass is 12 dB. The break frequencies are not the same, and... | |
| Servo Controlled Arm Hiho...An important detail about the Sony linear tracking servo is that it does not move in and out, as you suggested. It only moves in. (Unless you pick up the arm). This is because the servo only modifies the RATE of movement, which is always in... | |
| Servo Controlled Arm Rotarius...I think you are talking about the vertical "Biotracing" servo, which is quite separate from the linear tracking arm. Sony made pivoting Biotracer arms also.By the way, I made a typo in my last posting. The spec tracking angle error is 0... | |
| Servo Controlled Arm Dan_ed...If groove spacing changes abruptly there will be a momentary change in tracking angle WITHIN THE SPEC RANGE OF 0.5 DEGREES. (Remember, the arm pivots). A properly designed servo does not overshoot or hunt. Digital servos make it particula... | |
| Servo Controlled Arm Dan_ed...The main points are as follows...1...The arm pivots, just like a conventional arm. This prevents any side forces due to the servo.2...The pivot point is moved as the record plays.3...The rate of movement is biased to match nominal groove ... | |
| Servo Controlled Arm I have a Sony PS X800 TT that has a linear tracking as well as the "biotracing (vertical servo) arm. All the criticisms of servos that audiophiles cite do not apply to a well designed servo. No hunting, no offset. The arm pivots, so the servo does... |
