Class D amplifiers, first proposed in 1958, have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? What is needed to make a “good” audio Class D amplifier? What are the ...
However, a mirror with a coating of this type is relatively narrowband. That means it can’t be used at wavelengths other than the exact laser wavelength it was designed for. Also, the peak reflectance of all thin film mirror coatings shifts with angle. So, a laser line mirror designed fo...
So, a hi-fi setup would include speakers, an amplifier, and other physical audio components. Lossless vs. hi-resolution audio Hi-resolution audio, or hi-res audio for short, is related to lossless audio but not exactly the same. Above, we mentioned that compression can result in a lossy ...
The outcome of that research is an improved copper voice-coil and glass-fibre former, pushed by ceramic magnets and a 500W class-D Pascal amplifier. It gives the 9in long-excursion woofer even more grip on the bottom without sacrificing a deep frequency response. ...
A high-power RF amplifier generates the field, which is swept in frequency from 80 MHz to 1 GHz. The device under test is placed within the cell and exposed to the electric field. A field-strength monitor within the cell provides feedback to maintain a constant field level as the ...
A Smurf attack amplifier is acomponent of Smurf attacks that increases their damage potential. The amplification factor correlates to the number of hosts on the victim’s IP broadcast network. For example, an IP broadcast network with 300 hosts will yield 300 responses for every fake ICMP echo ...
The Sonos sports dual-angled tweeters alongside a single woofer and a Class D amplifier for each driver, while custom waveguides also help to direct the frequencies more adeptly. We lamented the lack of any higher-quality codec in our first-gen Move review, so it's frustrating that Sonos ...
Vocoder D (8-Band) All new FX types are side-chainable, which means they have 2 inputs (in the regular FX chain). In case of the Vocoders, the normal input 1 is the Modulator (voice) signal, while the input 2 is the Carrier (synth) signal. ...
Inside, Ruark has packed a suite of high-spec technology worthy of any audiophile. Two 30mm silk dome tweeters, two 100mm paper cone woofers, and a powerful Class A-B amplifier deliver rich, nuanced sound with extraordinary clarity.
If you are like most consumers, you think "3D Ready" means a projector is ready to display 3D in all its various forms. Well, that's not quite true. Many 3D Ready projectors are available right now, as you read this article, but 3D is still a confusing subject. What 3D signal sourc...
