Powering raspberry pi from battery

Most of the focus on getting better TV sound has been on soundbars , but when Klipsch introduced The Fives in 2020, it reminded us that a really good set of stereo speakers can sometimes be the best solution of all. Apparently, we’re not the only ones who thought so because Klipsch has introduced two new Heritage Wireless models — The Sevens ($1,299) and The Nines ($1,499) — which take the same winning formula from The Fives and add more power for bigger spaces. Both models are available starting January 31 at Klipsch.com, in both ebony and walnut wood finishes. The Sevens and The Nines use the same midcentury modern design as The Fives, with wooden enclosures and removable cloth grilles. Easy access controls are placed on the top of the right channel speaker, giving you the ability to switch sources and adjust volume without needing a remote — though a remote is also included for full couch-based control. On the back panel, you’ll find a variety of inputs including … [Read more...] about Klipsch expands its powered speakers with The Sevens and Nines | Digital Trends

New York-based prestige audio brand McIntosh this week launched the MHT300, an $8,000, 7.2-channel home theater receiver that boasts a monstrous 120 watts to 150 watts per channel of power. That’s right: up to 1,050 total watts. But what’s impressive about this is that all that legendary McIntosh power is distributed to all seven channels, making for some serious movie-watching sound from all directions. Well, kinda. The McIntosh MHT300 Home Theater Receiver will let you hear “every explosion, car chase, and high-speed fighter jet flyby,” according to a press release, at 120 watts per channel into 8-Ohm speakers or 150 watts per channel with 4-Ohm speakers, with all seven channels driven. And while this setup is sure to deliver pristine McIntosh sound, which may be great for most people, there’s a potentially expensive compromise when it comes to adding the height channels for Dolby Atmos surround sound. By default, those seven powered channels represent the front-left, center, … [Read more...] about McIntosh’s new $8,000 AVR: big power, with a Dolby Atmos catch | Digital Trends

The Marshall Middleton ($299) is the company’s latest addition to its lineup of guitar amp-inspired Bluetooth speakers , and it’s available starting January 31 at marshallheadphones.com . The Middleton, as its name somewhat suggests, sits in the middle of the Marshall portable family — it shares the same rectangular shape as the Emberton II but is heavier and more powerful than the Stockton II. What makes the Middleton stand out is its unique quad-driver configuration, which places speakers on all four sides. There are two full-range drivers, each with its own 20-watt amplifier, and two tweeters, powered by a pair of 10-watt amps.  The Middleton uses the same “true stereophonic” system as the Emberton II to achieve what the company calls multidirectional, 360-degree stereo sound. Previous Next 1 of 4 Inside is a rechargeable battery that Marshall claims will power the Middleton for more than 20 hours, and it can also do … [Read more...] about Marshall’s latest Bluetooth speaker has four drivers for 360 sound | Digital Trends

Samsung has courted a ton of flak in the past for copying Apple, but in 2023, that penchant for imitating its archrival just might prove to be helpful for smartphone shoppers. Soon after revealing the asking price of the Galaxy S23 trio, Samsung announced that its previous flagship is officially getting a price cut — rather than getting axed from retail shelves. Contents A surprisingly good value Samsung enters the pit roaring Apple has been doing the same for years, and it has actually proved to be a wise move for everyone. With a lowered asking price worth a hundred dollars or more, buyers can digest the premium of spending on an iPhone with a lighter hit on their wallets . Of course, it also helps that buying a previous-generation iPhone doesn’t come with any serious FOMO, because Apple is usually quite modest with generation-over-generation upgrades. This year, Samsung is serving Apple’s formula to Android phone enthusiasts. The Galaxy S22 , which … [Read more...] about How the Galaxy S23 copies the iPhone, and why it’s great | Digital Trends
