| Analog Tuner Existence..... Once in a while the local NPR station (WAMC) stops its left wing diatribe long enough to broadcast some live music. Even over the radio music that has never been run through a tape recorder sounds more real. | |
| Analog Tuner Existence..... Perhaps digital radio will produce decent stereo. Except in strong signal areas the difference signal that is combined with the mono (sum) signal to derive stereo is so noisy that it is often best to switch to mono reception. | |
| Noisy vinyl from Classic Records In their time LP recordings were amazing technology. They yield excellent sound, but with some degree of surface noise. The surface noise is an inherent characteristic of the technology, sliding contact between two physical objects. It can be mini... | |
| Goodmans Speakers Back in the 1950s when I started building speaker systems there were two lines of British drivers that were considered to be best...Wharfedale and Goodmans. Of course there were also Tanoy, Bozac, and some others, but they were not that common. I ... | |
| Is Phase and polarity the same thing? Magfan...I rebuilt my MG1.6 crossovers, so I am familiar with them. The low pass (woofer) is 12dB and the high pass is 6 dB. The break frequencies are quite different (I can't remember the exact numbers). The phase of the passed signal changes ove... | |
| Electrical Question - dumb one - but a good one The current rating is based on overheating if the specified current is carried continuously. A 15 amp rated plug will handle any current surge that your amp will demand just as well as a 20 amp plug. | |
| Is Phase and polarity the same thing? Magfan...6dB..... 90 degrees (not zero)12 dB...180 degrees18 dB...270 degrees24 dB...360 degrees (which is like zero) | |
| Is Phase and polarity the same thing? Tbg...As I read your comment about some drivers being hooked up out of phase, it seemed as if you had no idea why they would do this. So I explained.Even if cone excursion matches the electrical signal without delay (doubtful) the resulting sound ... | |
| Is Phase and polarity the same thing? When a crossover has a 180 degree phase shift at the crossover frequency (12 dB) connection of the driver out of phase is the right thing to do.Neither the mic diaphram nor the speaker cone moves in sync with the electrical signal, so it is not as... | |
| Noisy vinyl from Classic Records "Left channel only" you say. Damage or defects in the vinyl groove would not be clever enough to affect only the groove modulation direction associated with the Left channel. The problem must be in the signal mix. | |
| Is there such a thing as tube sound in a ss? Mcondon...The CarverPro ZR1600 amp (I have three of them) was described as "tube-like" by various reviewers when it came out some years ago. The ZR1600 uses the TriPath module, which audiophiles are not faniliar with. (It's all ICE and sometimes H... | |
| Rules for matching subwoofers to room size Audiokinesis...You are correct about phase coherency being overrated by audiophiles. I threw that out as one plausible explanation of what I personally hear even if you don't :-)Many years ago I read an interesting observation about an experiment ... | |
| Rules for matching subwoofers to room size Audiokinesis...I think it "really does matter" that the thump of the drum and the higher frequency percussive sounds come fromn the same location...for phase coherency if nothing else. Contrary to what you said I think that most subwoofers have 24... | |
| Is there such a thing as tube sound in a ss? Some say that certain "digital" amps have a tube-like sound. With a digital amp the characteristics of the amplification devices, be they tubes or transistors, are out of the picture, and the sound will depend on the amplification algorithm. This ... | |
| Rules for matching subwoofers to room size This business about not being able to locate a subwoofer is simply untrue in my experience. Perhaps it is based on experiments with pure sine waves. With the possible exception of a flute, musical instruments don't produce pure sine waves. A drum ... |
