| why does digital volume control cause loss in info Almarg...I know about this chip because one failed in my MAP1 and was replaced (on waranty). Sorry I can't cite the exact part number. There are three of these 2-channel chips in the six channel preamp, so they can't cost that much. | |
| why does digital volume control cause loss in info There is a common digital volume control chip, used in my McCormack MAP1 six channel preamp, which does 1/2 dB steps. It is a stepped attenuator, and no motor is involved. If such a chip follows the D/A conversion no bits are lost. If an analog ou... | |
| why does digital volume control cause loss in info It doesn't. Digital volume control is commonly implemented using a module that is essentially a digitally controlled stepped attenuator. The signal is analog. The notion of "dropping bits" is pure myth. | |
| Best speakers for home theater/voice clarity? Shadorne...Except for "Global Warming" :-) | |
| Dynamic Headroom Kijanki...The 47 volts you cite is DC. Allowing for a 3 volt drop through the output transistors this suggests that the amp can swing +/- 44 volts. But that 44 volts is the peak of the signal. For a sine wave signal this would allow 228 watts RMS.... | |
| Dynamic Headroom Kijanki...So it seems that the FTC power spec IS supposed to cover thermal considerations. That might be very reasonable for pro amps which play highly compressed and peak limited music at maximum volume. I play music on my system very loudly (but... | |
| Dynamic Headroom Kijanki...Agreed that "Unlimited time" would be more than "Continuous" in the definition of power. I don't know how the spec is exactly defined but I think that "continuous" could be 5 seconds or so. This would be long enough to reflect any power ... | |
| Best speakers for home theater/voice clarity? Speech inteligibility is maximized by limited and contoured frequency response, which, of course, is not good for music. Unless the speech is localized in one channel (center) you are between a rock and a hard place. | |
| Dynamic Headroom Almarg...I don't agree with your description of the power supply as "weak". It may have been designed that way.I like to think about this issue in terms of voltage. The amplifier delivers an electrical output which is the same shape as the input s... | |
| Crossovers, why so few options? Stilljd...Experimentation is always interesting. I have not biamped my three MG1.6s unless you count the Subwoofer/mains as biamping. I did rebuild the passive crossovers using AWG10 air coils that are externally mounted. Because my Maggies will n... | |
| Crossovers, why so few options? The MG 1.6 crossover is a simple HI/LO divider and has none of the extra elements that Kal refers to. It is, therefore appropriate to consider for biamping. However, the stock crossover does have different break frequencies and slopes for the HI a... | |
| Maggies a waste if only 3' from backwall? Philjolet...The MG 1.6 has a QR tweeter. QR means Quasi Ribbon, and amounts to no more than a section of the diaphram with lightweight conductors to extend HF response. I do prefer the QR approach over the true ribbon, perhaps because the common t... | |
| Crossovers, why so few options? Kal...The passive crossover elements which address driver characteristics can be retained while the basic HI/LO filtering is done at line level. | |
| SHOW attendees: please post speaker reports here Maggies are planars. If you don't appreciate planar characteristics you won't like Maggies. | |
| least harmful light dimmer Dimmers go a bad name for causing noise when they were a new thing. With those sold today I experience no problems. I even have one on the light over my turntable, and I can't tell from the sound if it is on or off. |
