Power your speakers with the latest amplifier technology with the Ashly MA250.8, an 8-channel power amplifier that delivers 250W of power per channel. The amplifier incorporates Ashly's proprietary advanced intelligent power-sharing and ultra-efficient D-MAX amplifier technology for the cleanest and most reliable performance with lower power draw. Additionally, the MA250.8's multi-mode capabilities allow it to accommodate different speaker types, switchable per channel from Low Z (2, 4, and 8 ohms) to Hi Z (25, 70, or 100V).

The MA250.8 is 2 RU and can be mounted into a standard 19" rack enclosure. The rear panel features removable Euroblock input and output connections as well as remote VC ports and switchable 80 Hz HPF and Clip Limiter on each channel. The front panel provides a volume control knob for each channel and comprehensive LED indicators for levels and amplifier status.

AI Power Sharing

Advanced intelligent power sharing dynamically distributes power to channels where needed and adapts to varying conditions. Power sharing allows the amplifier to balance power between channels to match asymmetrical speaker loads. The advanced AI-based power sharing picks up where other amplifiers leave off by intelligently and automatically adapting to your varying power demands.

Ultra-High Efficiency

You can operate as many as any three MA amps on a single 20A service. Ashly optimized active air cooling using a newly developed SailFlow design, which moves the air along a selective path, to where it's needed most. Coupled with the new Ashly-engineered ultra-high-speed switching power-supply, the use of high-speed, lossless Silicone-Carbide switches, and intelligent power management, the end-result is nothing short of stunning.

Nice tactile feel
Style: 2024 Model
Works right out of the box. Installation was simple. Probably should have gotten the next small size, as it is larger than I expected. But I like the key response and the feel of the mouse, so I'm keeping it. Nice, inexpensive keyboard and mouse.

Well, Logi (Logitech)'s normally great record has been broken...
Style: 2024 Model
Gotta vent. I've had my Logitech K800 forever and a day and LOVED it. Never any performance problems, smooth, comfortable, easy to use, and took a beating daily for years. Got it through work, so it was more expensive than your usual, but it couldn't last forever. It started being unable to take a charge, so I knew I would have to retire it. (They stopped making these (WHY???) and they're selling after-market for a fortune.) I have Logi all things keyboard, mouse, etc., so went with them again. Bought a K650, but out of the gate, it started doing weird stuff, like repeating keys when you weren't even touching the keyboard, jamming up, or just stopping functioning. Did all the usual troubleshooting, but nothing worked. Just to save time, I sent it back here and replaced it with an MK540. Son of a gun if it didn't start immediately doing the same things. NOW I was cranky, so I did my online research and learned these are well known problems for others, who also couldn't solve them. I then went to Logi tech support. Got a level 1 person who walked me through the standard steps I'd already done multiple times (Did you turn it off and on again? :-D), gave me long lists of things to try, then at the end, when nothing worked said, "Well, it's within 30 days so just return it to the seller, and here's a link to our other keyboards." "Ummm," I said, "this is the exact same circumstance with two DIFFERENT keyboards in a row. As I had no trouble with my previous Logi keyboard, and nothing else has changed on my end, it seems logical that the problem is with the new software, hardware or some QA problem with producing these models. Why would I go buy another one when we don't know WHY it's doing this, suggesting I could go through this all over again?" (BTW, a MAJOR inconvenience for days). Her answer (twice): "Don't worry, it'll be fine, just go get another one." OMG. Stubborn, so I gave it a third shot (MX Mechanical) now for 3x the money hoping better quality would help, but guess what? I've now received my 3rd notice from Amazon saying delivery will be delayed, this time with no date estimate known. I tried, Logi, but even I am done. Buying a highly rated other keyboard that has all the features I need. Logi, not sure what you're doing with these membrane ones (vs. mechanical), but it's not working. If you could ship me a K800, I'd so appreciate it. :-D K

Perfect keyboard with wireless Unifying Receiver
Style: 2024 Model
I've tried and had to return multiple $100+ keyboards due to irregular F1-F12 or arrow key layouts, dreaded Fn key in the lower-left, mushy key travel feel, etc. I've been using exclusively Logitech keyboards & mice since the 90's, but gave up and tried venturing to other brands like Keychron (had issue with inadvertent key presses when pausing fingers over keys). But this simple keyboard just gets it right. I didn't even need the bundled mouse since I use Logitech MX Master 2S, but like that I can use the same Logi Unifying Receiver and Options+ software (optional). There are dedicated keys: * power on/off colored slider * play/rewind/ff * volume mute/down/up * calculator * battery level * 2 user-configurable buttons * Fn+ F1-F8 are also configurable The are 3 height levels, built-in mini palm rest (I still use a big keyboard mat beneath), slot for Unifying Receiver and 2 AA under the battery cover. Minor issue is the batteries clack when using the F5-F12 keys (just below where the batteries are), but I taped a little strip of foam on the inner side of the battery cover to resolve it. Also great is Logitech MK270, which is more compact, light, and perfect for the road. Both have amazing battery life.
