AP4KAmplifiers 2x 1800w per channel Amplifier An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.
Amplifiers 2x 1800w per channel Amplifier
An impedance mode switch on the back panel of the amplifier allows the user to select full output power into either a two or four ohm load for maximum application flexibility. This means this compact two rack space amplifier can deliver up to 3600 watts of clean, pure power into either 4 or 8 ohm loads (bridged), making it a perfect solution for virtually any touring live sound, club system or installation.
The internal signal path has been optimized and a toroidal transformer is used in the AP4K design - both serving to reduce hum and noise in practical real-world applications. It's three-tier Class-H design approaches efficiency normally associated with Class-D technology; yet provides the superior transient response and low distortion of the best analog designs.
Features
- Delivers 1800 watts per channel into either 2 or 4 ohm load
(3600 watts bridged into 4 or 8 ohms) - Proven Ultra Reliable Class-H Design
- Easily Handles Reactive Phase Shifted Loads
- Advanced Protection Schemes Including DC Current, Load, Thermal & Breaker Protection
- Transparent User-Defeatable Peak Limiter Circuits
- Soft Turn-On Circuit Protects Speakers and Prevents Nuisance Breaker Tripping During Power Up
- Concise Front Panel Metering and Status LED's
- Speakon™ and Binding Post Outputs
- Balanced XLR and ¼-inch TRS Inputs
- All-Steel Chassis Construction
- Made in Canada

Great quality Coach Bag!!
Size: One Size, Color: B4/Maple Maple
Coach Tabby 20: Great small bag with lots of individual compartments...for a wallet, phone, comb, keys, earbuds, & lip gloss. The color is a medium dark brown with a lighter brown highlighting Coach signature...it goes with everything! I especially like the expandable shoulder strap to crossbody wear, with plenty of room to have it hang long if you like...and not have the strap only go to your side when wearing it crossbody...it actually can go to my hip and I am 5'6'. I've received complements on it...one I especially liked was a young girl cashier, who looked at it with big eyes, smiled and said, "Cute Bag!". I'm in my early 60's so that felt kinda great!!! ;) I bought on Amazon because Amazon speed delivers!! Thank you Amazon!

Comfort Meets Performance — Nike Men’s Journey Run Road Running Shoes
Size: 10.5, Color: Black/Summit White/Anthracite/Cyber
I picked up the Nike Men’s Journey Run Road Running Shoes on a whim, and they turned out to be a great surprise. From the first wear, they felt comfortable and lightweight, with cushioning that makes walking and running on pavement much easier on the feet. They don’t feel overly stiff or bulky, which I appreciate for everyday use.
What I like most is how versatile they are. I’ve worn them for short runs, gym workouts, and even casual outings, and they’ve held up well in all situations. The fit is true to size, and the upper feels breathable enough to stay comfortable throughout the day. They also have a clean, simple look that pairs well with both athletic and casual clothes.
Traction has been solid on roads and sidewalks, and I haven’t noticed any slipping, even on slightly wet surfaces. While they may not be designed for competitive racing, they’re perfect for daily training, walking, or anyone looking for a reliable, comfortable running shoe.
Overall, the Nike Journey Run shoes offer good comfort, dependable performance, and everyday style. A solid choice if you want a no-nonsense running shoe that you can wear beyond just your workouts.

Versatile sneakers. The upper makes the difference.
Size: 11, Color: Black/Smoke Grey/Medium Ash
Very good quality shoes for this price.
My impressions:
1. The Flyknit upper feels very soft and comfortable. I don't get the rough, scratchy feel of some lower-quality options. It also disperses heat very well.
2. The midsole is firm, but not overly hard. I find it well-balanced, as it has good shock absorption while still being soft enough to cushion the soles of my feet.
3. They're versatile. For me, especially the black ones with the dark gray sole, they work for casual wear, going to the gym, walking, and short, light runs.
4. I consider them very decent shoes for walking and short runs under 5k.

Offer lots of support and traction- perfect gym shoes
So comfortable- they offer a lot of support and I can tell they will last for a long time (and I’m hard on my gym shoes!). I’m actually a female but I sized down and they fit perfectly. I found them on sale and definitely recommend them as they are well worth the price.

Comfortable nike running shoes.
Size: 13, Color: Black/Summit White/Anthracite/Cyber, Size: 13, Color: Black/Summit White/Anthracite/Cyber
Nice and comfortable from the moment that I put them on my feet. Feels like you’re walking on memory foam. You have to buy comfortable shoes when you’re on your feet all day. I do Amazon Flex in. These will be perfect although I have several pairs so that way, the shoe lasts longer. Definitely would buy these in different colors very satisfied.
