McIntosh Unleashes Its Brand New Monster Power Amplifier With A Hefty 450W Per Channel

Forbes - Tech

A case in point is the new MC462 Quad Balanced Power Amplifier from venerable US audio manufacturer McIntosh. This grand old brand has been producing high-end amplification since 1949 from the company's Binghamton factory in New York. Starting out with tube-based amplifiers, the company has evolved its offerings to include high-end audio components such as tuners, preamplifiers, power amplifiers, CD decks and even vinyl turntables. The company's price tags are never small but the performance is large and a McIntosh set-up is often an audiophile's idea of Nirvana.



Deep Learning A.I. Can Imitate The Sound Of Iconic Guitar Amps Digital Trends

#artificialintelligence

Music making is increasingly digitized here in 2020, but some analog audio effects are still very difficult to reproduce in this way. One of those effects is the kind of screeching guitar distortion favored by rock gods everywhere. Up to now, these effects, which involve guitar amplifiers, have been next to impossible to re-create digitally. That's now changed thanks to the work of researchers in the department of signal processing and acoustics at Finland's Aalto University. Using deep learning artificial intelligence (A.I.), they have created a neural network for guitar distortion modeling that, for the first time, can fool blind-test listeners into thinking it's the genuine article.

The southern amplifier

Science

Earth's natural climate variability of the past 2.6 million years has been dominated by glacial-interglacial cycles. These cycles are paced by variations in incoming solar radiation due to changes in Earth's orbit around the Sun. Feedbacks in the Earth system, including variations in greenhouse gas concentrations and the growth and retreat of Northern Hemispheric ice sheets, amplify the effects of the insolation changes. The characteristics and amplitude of the cycles changed fundamentally at the mid-Pleistocene transition, between 1.25 million and 700,000 years ago. On page 1080 of this issue, Hasenfratz et al. (1) report that this transition was associated with increased Southern Ocean stratification and reduced upwelling during glacial times.
