Ashly NX1504 overview
The nX Series 4-Channel Multi-Mode Power Amplifier from Ashly is capable of driving 2, 4, and 8 ohms loads at full power and offers a maximum rated output power of 150W per channel at 25V, 70V, and 100V modes. It features a universal switch-mode power supply with PFC (Power Factor Correction) that operates from 70 to 270 VAC. The multi-mode output capability allows each individual amplifier output channel to be set for low-impedance (2, 4, and 8 Ohms) or constant voltage (25, 70, or 100V) operation using DIP switches.
The amplifier has power-saving Ashly EMS (Energy Management System) that provides an automatic sleep-mode drawing less than 1W. It is suitable for live sound and fixed installation sound systems in stadiums, arenas, performance venues, places of worship, and convention centers.
- Utilizes Class-D switching amplifier technology
- Selectable 80 Hz second-order Hi-pass filter, limiter, and input gain per channel
- Remote DC level control per channel
- Extensive protection circuitry, continuously variable cooling fan
- Euroblock input and loudspeaker connectors
- Detachable AC mains line-cord connector
- CE, FCC, RoHS certified

Super Cute and Dainty—Perfect for Gifting!
I ordered this dainty pink heart initial necklace as a birthday gift, and it is honestly so adorable in person. The pink heart has a really nice, vibrant color, and the gold finish looks super trendy and clean. It’s the perfect length (16 inches with a 2-inch extender), so it sits right on the collarbone and layers really well with other gold chains.
It makes for a really sweet, personalized gift for a mom, friend, or even a preteen girl who loves that "soft girl" aesthetic. The initial letter is subtle but clear, and it doesn't feel overly heavy around your neck.
Why I'm giving it 4 stars instead of 5:
The only real downside is that the chain is very thin and delicate. You definitely have to be careful not to yank it, and I wouldn't recommend sleeping in it or wearing it in the shower if you want the gold plating to last. It’s also smaller than it looks in some of the product pictures, so just make sure your expecting something truly miniature and "dainty."
Overall, for the price point, it’s an awesome piece of trendy jewelry. It looks much more expensive than it actually is, and the packaging makes it super easy to gift right out of the box.

Pretty initial necklace
Color: A, Color: A
This is a cute necklace that I ordered for my daughter. This necklace is nice because it's decent quality but I wouldn't be devastated if it broke or got lost. The initial is nicely made and the chain is delicate. It's the perfect size for my 7 year old and I think my 11 year old would also like it. When I ordered it, it was $15 but now there is a coupon to make it $12 which is a great value. I would buy it for myself if it was silver. It comes in a nice box that makes it great for gifting.

Great for daughter or friend!
Color: E, Color: E
This is absolutely perfect for a daughter for Valentine’s Day or a gift just to give. The initial is in a gold with a gold chain and a precious pink heart. Easy to use gold clasp to put it on or off. The chain seems pretty regular like most chains, but seems durable enough to wear everyday. It hasn’t tarnished or turned any necks green so it’s skin safe I would say. Wouldn’t recommend showering with it, but it has stayed gold with no tarnish. It is simple and cute for a friend, daughter, even a mom.

Great for my 8 year old daughter. Dainty and elegant
Color: K, Color: K
This necklace is perfect for my 8 year old daughter. She loves dressing up her clothes with fun necklaces and this one is so elegant and pretty.
The chain is very thin so be mindful of that. It could definitely easily break if not taken care of. I do like that it has an adjustable clasp so I can shorten it to where she likes it. The chain is actually a good length so there is room to grow.
It is plated so definitely not recommended to wear in water of any kind as it will eventually turn. For the price it’s a good little necklace for younger girls and having their initial on it will be something special for them.
The box it comes in is sweet and has a really motivational saying in it.

Must have
This initial necklace is adorable. The gold tone is pretty and shiny without looking cheap, and the pink heart adds the perfect little pop of color. It feels lightweight but well made, and the clasp is easy to use while still feeling secure. I bought it for my daughter and it’s the perfect everyday necklace cute, simple, and special without being over the top. It’s held up well so far with no discoloration, and it looks great layered or worn alone. Such a great little personalized piece.
