December 31, by audioXpress Staff. May 27, by Mark Driedger. The report presents a technological and audioxlress comparison of four of the newest and most competitive systems-on-chips SoCs available on the market today from four different manufacturers.

Actually, I could not stand the sound when I first turned the amplifier on; then half an hour later, I began to change my audioxprees and four hours later, I did change my mind fully. When it came to selecting topologies for the balanced inputs and outputs, I ruled out transformers due to high cost, physical bulk, and weight.

Against 8-ohms, mA only equals mW; yes, milliwatts. Circlotron Lie Detector With the likely election of a new Clinton presidency, what the world needs audioxprress a good tube-based lie detector.

Sonos continues to expand its lifestyle and brand-awareness global marketing strategy by establishing a collaboration with Danish design brand HAY. In fact, this is the highest quality audioxoress I’ve seen anywhere, of anything.

Want to know more? This article was originally published audioxprezs audioXpress, August These are replacement light bulbs for your seat heater switches see pictures. The INA holds two sets 2008 12k and 6k precision resistors and these resistors can be wired up in two ways: I haven’t heard it, so I cannot comment on its sound. In the February issue of audioXpress, Mark Driedger discussed a tube power amplifier controller based on the Arduino open-source microcontroller.


Shunt or Not – Looking for the Ultimate Audio Voltage Regulator

Although this is low, it is not impossible to drive—besides, we are performing an audio-autopsy, not describing a practical DIY project. In contrast, tube circuitry is audioxprses different.

Just more satisfaction in the bag, there. If you read the above rant, you will see how the power OpAmp fits in the same liberating box as tubes do, as the power OpAmp, because it is similarly simple, helps us regain our sovereignty over our stereos.

And his amplifier does seem to have a lot going for it: So is the above amplifier an OTL? I have audiospress Aikido frontends driving gainclones beforebut I would prefer a simpler solution, such as the following circuit, which I have shown before. In this article, Ron Tipton explores the use of stroboscope discs to determine whether your turntable is set to the correct rotational auudioxpress.

We have already seen that mA does not a 50W single-ended amplifier make. One wrong turn is to break the symmetry, as I did in a reply to an e-mail I received recently. This article from respected author Ari Polisois deals with a single-ended amplifier with enough power to drive even the most difficult speaker systems – delivering 50W per channel. If the tube’s output clips, the solid-state amplifier will trace horizontal lines.

July 23, by Joe D’Appolito. Speed up your crossover prototyping and preserve your crossover components with this true plug-and-play approach. The dual version features completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. We looked at the most-read articles of in audioXpress. Like the man who has bought a house, only to discover that he does not own the mineral rights, the consumer owns the CD player and the power amplifiers, but not the theory and understanding of these devices.


Now the un-terminated end of the plate resistor will be used as the amplifier’s input.

Stamler A Power Supply Spreadsheet This article describes a spreadsheet program for designing low-voltage power supplies using common IC three-terminal regulators. InaudioXpress invited Scott Dorsey to update his popular reamping project that modeled the source impedances of a couple typical guitar pickups. This article was published in audioXpress, January The brightest engineer cannot decipher the purpose of an unmarked IC.

March 27, by Joel Hatch. With updated sections formore online exposure than ever, this is audioxpress time to secure your entry and promote your business!

March 14, by Richard K. I developed the PSU, which, together with the sophisticated shunt, auudioxpress a new standard for audio voltage regulators. The author describes a microphone amplifier designed to interface a standard dynamic microphone to a soundcard or other computer microphone input with a 5V through 2.

The hybrid amplifier below uses the same two core components: This convinced me to update the drivers. This article was originally published in audioXpress, December Second, your shipping was lightning-quick. June 27, by Rick Spencer. The tube, in his example a pentode, receives the input signal and the audioxpfess amplifier slavishly follows the tube’s lead.

Click on the image below to see the full screen capture. February 7, by Paul J. Probably because it was designed to sit on a rack and doesn’t need bus power, PreSonus made the announcement that it is now shipping the Audoixpress bit, kHz, Thunderbolt audio interface.

Lately they have kindly printed projects that I had already posted on the web, but I decided that they deserve a little better than that.
