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

I LOVE this sunscreen!! Super affordable and lightweight for your skin!
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
I love this sunscreen!! Love it so much I bought 3 bottles of it!
Super lightweight and blends right into the skin, and I don’t feel not sticky!
I got super excited and got this primarily because it’s lightweight, super affordable, SPF 50 for high protection, and it said there’s no alcohol or fragrance…heres the catch tho, there IS a slight sunscreen smell, but you only notice it when applying it and if you keeping smelling it on yourself up close during the day.
Other than that, it’s truly fragrance free in the sense that you aren’t just standing there doing your thing, and keep getting HIT with the scent of sunscreen for hours, like other sunscreens! The scent is extremely light and pleasant when you go to smell it on yourself.
Don’t EVER discontinue this please please please!!!!

It’s great! So light weight!
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I have been testing this out for a month now.
I love it. This does have avobenzone in it, and because of that, I do NOT put it around my eyes as avobenzone is a chemical sunscreen ingredient that typically tends to cause the of sensation of burning eyes! At least for me it does.
I use an Australian sunscreen around my eyes that doesn’t have anything that irritates my eyes. So for the rest of my face, this stuff is great. It literally is so serum like sinks into your skin within five minutes or sooner. Now it’s not the most hydrating thing in the world so if you have a dry skin, you still wanna go in with a moisturizer before however, if you have oily skin, this is your girl right here. Skin like finish, not super matte and not dewy at all. I do not wear primer so I don’t know how it plays with that. Works great under my makeup and has never caused pilling.
Quick, easy, simple ingredients, definitely sensitive skin friendly, and no fragrance at an affordable cost-effective price! Now if only banana boat decided to go cruelty free😭
9/10 bc not CF 💔

Great sensitive skin sunscreen
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Love this! I have sensitive skin. this did not sting my eyes, or burn my cheeks. Left no white cast. I'm not noticing any scent. It just feels like bare skin, it's not heavy, drying, oily or sticky. No pilling. Went on smooth, not streaky, looks like skin once dried down, not patchy. I hope they keep this in stock forever!

Hydrating Itch Relief for Sensitive, Reactive Skin
I recently dealt with an allergic reaction that left me with red, intensely itchy hives across my body. Medication helped calm most of the symptoms, but this itch relief balm from Aveeno made a noticeable difference in soothing the lingering itch and rehydrating my irritated skin. The formula is very concentrated, so only a small amount is needed to cover a large area, and it begins to work quickly. There is no added fragrance, which is ideal when your skin is already reactive and sensitive.
The jar is generously sized, and the wide opening makes it easy to dip your fingertips in and smooth the balm over affected areas without fuss. The texture spreads well, absorbs cleanly, and leaves the skin feeling comforted rather than coated. I found it especially helpful during the recovery phase when my skin still felt dry and unsettled. Definitely recommend for anyone dealing with post‑reaction itch or general irritation.

Really good eczema lotion for 4 month old baby
Love this lotion. I’ve been using it for almost two weeks now on my baby who has eczema, I didn’t wanna waste money on the baby version because what if it isn’t as powerful so I got this one and now my baby’s cheeks aren’t red and spotty. Honestly didn’t think it would work but it’s working great, I add it all over his body especially his face after he showers and it helps his itchiness at night. During the day I add some if the redness looks like it’s coming back and it ends up going away mid day. I’ve used about 4-5 other lotions that didn’t work so I’m very happy about this one.
