| Holographic imaging Roger, the term for the time it takes a signal to pass through an amplifier is called Propagation Delay. It is usually a constant at all frequencies within the pass band of the amplifier circuit. But- has nothing to do with Doppler Effect.I notice... | |
| Highly efficient speakers to pair with my SET amp I can second the Decware choice, along with a recommendation to look at Tonian Labs. The Ref3A stuff is excellent also, maybe not as efficient as ideal for an SET, but an easy load, and that's important too. | |
| Holographic imaging Roger, I have many times had test tones being played through loudspeakers with microphones and frequency counters in use- never in the years of working in and out of the recording studio have I ever observed a connection between gain and pitch as ... | |
| Highly efficient speakers to pair with my SET amp Betsy- if you are running an SET with 18 watts, you need more efficiency than 92 db to really hear what the amp is all about. One inexpensive way to get that is the ZU Druid- but if you look into them, make sure they are a new pair or a set that h... | |
| Holographic imaging Tbg, sorry, but, **there is no doppler effect in an amplifier**! If a designer of a 'holographic processor' tells you something like that, turn around and run as hard as you can!You have propagation delay in any amplifier circuit but that does not... | |
| Help mismatch maybe? Mapman, ya learn something new every day. I would not have thought that Quad would do something like that... from the looks of it, with the woofers in parallel and Quad's tendency in the last 20 years to use transistors, my bet is that these speak... | |
| Help mismatch maybe? Mapman, that could be- sort of. The problem is that ESLs in general do not have an impedance curve based on box or free air resonance. It is based loosely on a capacitance. Consequently, it will require constant power with respect to impedance, no... | |
| The focus and air lie So- through all of this no-one has really been able to make the case about how 'focus' and 'air' are a lie, although like a number of other threads on the 'gon, it does seem that the terms have almost as many meanings as the number of people that ... | |
| Looking for Polarity Invert Feature... If you have a recording that was done with 2 or 3 microphones, the effect can be heard. The effect has to do with the fact that audio waveforms are not always symmetrical. Take a look at an audio waveform on an oscilloscope and you will see what I... | |
| Help mismatch maybe? Mapman, the short answer is no. All you have to do is look at the designer's intent, particularly with the speaker designer. What is the amp that he is using in the design process? Is it tubed? If so, its likely that he has engineered the speaker ... | |
| Holographic imaging Doppler effect??! I would think that if there is any doppler effect in the recording, you would certainly **not** want to compensate for it. Otherwise you would not be playing it back right :)I get the feeling that a lot of these holography system... | |
| Looking for Polarity Invert Feature... One of the first preamps to have the invert feature was the original Atma-Sphere MP-1 (1989). It is the one signal processing feature that we have on our preamps (easy enough to do since our preamps are internally fully balanced). | |
| Help mismatch maybe? You have a mismatch. The speakers are a Power Paradigm device (they expect constant power from the amplifier, regardless of load), and your amplifiers so far are Voltage Paradigm (they make constant voltage regardless of load). Anytime you mix the... | |
| Class D and High Efficiency Speakers? High Efficiency speakers in general prefer an amplifier with a relatively high source impedance, due to the reactive nature of high efficiency drivers.The use of low output impedance amplifiers with high efficiency drivers is the reason why horns ... | |
| Holographic imaging Mapman, my experience has been that anywhere you can involve tubes in audio will help, as long as the tubes are in a competent circuit :) |
