AF companion amplifiers are designed to add powerful amplifier channels to AF bit processor amplifiers. A plug-and-play signal input harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a “straight wire” architecture, without analog preamp functions such as crossover filtering, and are intended for use with external processors. AF M6D boasts six high-fidelity amplified channels 135W x 6 @4?*, 220W x 6 @2?*, with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher-tolerance components deliver sound above and beyond the expectation of Class D – in an amazingly compact package! The audio band is extended up to 40 kHz earning the coveted High-Resolution certification. Bridging channel pairs results in 440W x 3 @4?*, guaranteeing flexible and powerful performance.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.

Versatile, comfortable and a delight to wear
Size: 10.5 Wide, Color: Army Green
Had never heard of this brand but needed a pair of waterproof boots for a trip to the PNW where we would hike in mountains, rainforest and beaches. I have a pair of Merrell Moab hiking shoes, but wanted something that covered more and were waterproof. These boots are amazing. They are one of the most comfortable shoes I own. I wore them everywhere and found I preferred them over other shoes throughout the trip. They stayed comfortable and dry no matter where we went, rivers, lakes or the ocean.
I’ve now worn them on several trips including a March trip to Bryce Canyon where we went from snow on some trails to the heat of the red rocks in others. I love these boots more every time I wear them.
I am a huge fan now. At the price they are a nobrainer. I would buy these Nortiv8 boots over and over again.

Good value for a $55 boot.
Size: 12, Color: Army Green
I like these boots because I have a wide foot and even though I bought the 12 and NOT the 12W there is plenty of width. Very comfortable boot. I have put this pair through about 1000 miles mostly on asphalt, ice and snow. Very little actual dirt/ rocky trails. I bought them for the waterproofness and ankle support. Now the soles are getting thin and I can feel small rocks through the soles. Plus the soles are beginning to separate from the uppers and they are no longer waterproof. Not bad for 1000 miles. Still, I feel For a $55 boot they are a good value. I am 6ft and weigh 250.

Worth Every Penny!
Size: 9, Color: Coyote
I absolutely love these boots! They are super light, comfortable and definitely waterproof. I took them on a camping trip for the weekend and I walked through creeks and puddles with no issues at all. No water got inside and they were comfortable all weekend. The only thing was the tongue did start to bother me a bit after the 3rd day. I have some pretty boney shins but a small cloth between my shins and the tongue helped a lot.
