Power your speakers with the latest amplifier technology with the Ashly MA-250.4, a 4-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 MA-250.4'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 MA-250.4 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.

Lovely sandals!
I highly recommend! These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.
