The Ashly FX-125.4 FX Series 125.4 is a multi-purpose installation DSP-equipped amplifier.

The FX Series' pedigree is the culmination of compact Class D design so successfully implemented in the FA Series and Ashly's years of providing easy-to-use software. Along with a newly incorporated DSP engine & software UI, FX takes amplification to new levels. FX is networkable via Ethernet for wired LAN connection, or directly via its built-in WiFi hotspot. No network router needed. FX allows system configurations that don't require additional equipment, such as stand-alone DSP or speaker system processors. All of that is in one box. That saves space, money & time.

With 6 models to choose from starting at 2 x 60W in a ½ RU to 4 x 500W in 2 RU, there's an FX that will fit just about any project. Each offers a healthy compliment of IO (include Digital SPDIF In & Out) and programmable integration ports for remote Volume control, GP triggers and more.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

Very nice, but sizing is inconsistent
Size: 10 Wide, Color: Ivory/White/British Tan
All of these Cole Haan shoes are extremely well made and I like the styling. On the other hand, the sizing is very inconsistent and you may end up having to do a lot of returns trying to find the right size. Then if you get a different color of it, you may find the sizing different yet again. If you find your right zie, they are really nice shoes at a very reasonable price for the quality.
