SMSL AD18 80 Watt x 2 Wireless Bluetooth Amplifier For Speaker

Es de un tamaño mas pequeño de lo que uno imaginaria, aunque el truco está en que tiene su eliminador de corriente casi del mismo tamaño que el aparato, para mi mejor, no estorba y se calienta menos asi. Múltiples entradas que le otorga gran flexibilidad a la hora de conectarlo, con salida amplificada directa a las bocinas y al subwofer. Lo conecté a unas bocinas Yamaha gama media que tenia y suena espectacular. Lo compré para una tableta buena pero con sonido horrible en verdad, tanto por sus bocinitas como por auriculares, la conecto por el puerto USB para "puentear" el dac de la misma y el cambio es abismal. Ahora pasó de ser solo para redes sociales a mi centro multimedia principal, escuchas todos los detalles de la música y las películas como home theatre, solo conectalo a unas buenas bocinas y sub y suena mejor que mis auriculares sennheiser hd599. El bluetooth se conecta también sin problemas y sin lag. Muy contento con la compra, lo recomiendo ampliamente.

This is my 2nd AD18 from SMSL. Been using it since 2019. Buying it for a family member. Its Afforable and I got significant time-limited discount offer from Amazon, if compared buy from Lazada! Seller was fast to ship and deliver the product. Thank you FINE MUSIC and Aamazon!

That's not very quality sound but i'm happy the same.Hope this amplifier will not die fast >.<

Works good when it comes to basic functionality. Controls are hard to master because everything is with one knob. Pushing knob is not consistently picking up what I want to do and turns volume instead. When in USB mode if left turned on and I turn on my PC I get loud speaker breaking sound. This is super annoying because I need to remember to turn it off every time I turn PC off. Bluetooth can connect only to 1 device. There is no firmware update available at all. Manufacturer do not care about this model. Consider buying newer model.

===EDIT=== Despite the product description claiming it's supported, there is a problem with this amplifier and the 96kHz USB sampling rate, where every so often the speakers will output a deafeningly loud cracking/hissing noise. This can be resolved by setting the sampling rate in windows back to the default 44.1kHz sampling rate. ========== I bought this wanting a compact, Bluetooth-enabled amplifier that would compliment my Wharfedale Diamond 220 speakers without breaking the bank while also not being so incredibly cheap the quality is in question. I'm a student so the limited space of my student bedroom meant I was looking for something with a compact package. I managed to get a relative bargain by getting a customer return from the Amazon Warehouse, thankfully it was in perfect condition as I've found the warehouse to be a bit hit-or-miss. The unit has loads of connectivity, I opted to use the USB connection (configured at 96kHz) from my laptop as this would bypass my laptop's sound card and instead send the digital signal directly to the amplifier. I connected my speakers up with some speaker cable bought from Richer Sounds and some soldered banana plugs from Amazon. I'm very happy with the sound, my speakers are rated for 50W each and this amplifier can go up to 80W per channel. This amplifier is **loud**, and I've gone nowhere near the limits. The proprietary 'SDB' EQ mode makes for a good listening experience, I also did a +2dB bass offset because I don't have a subwoofer (although there is a port for connecting an active/powered subwoofer in the future). I'm no audiophile but I think it sounds pretty great! The Bluetooth interface supports APT-X, a low-latency audio codec. My phone and laptop both support this, I think it sounds fantastic too. This is great if I'm watching movies in bed from my laptop as I can avoid using my laptop speakers, I do notice a tiny bit of lag where the audio is behind the video. (With VLC video player you can set a delay on the video if this annoys you). The display is good for configuring the amplifier, it works well and is intuitive enough. The remote is nice for controlling the volume and settings from in bed, however, the remote leaves a little to be desired... Sometimes the amplifier doesn't respond to button presses on the remote, so you have to press 'A' to sync it back to the amplifier. The remote won't allow you to change to modes without direct sight of the display because there are no buttons like 'Bluetooth', 'Aux', instead there's a button for switching between inputs, but you can't tell which is selected without sight of the display. If I'm in bed and want to switch from 'USB' to 'Bluetooth' it's hard to read what the display is set to from that distance. Overall I'm really pleased with this amplifier. It's small, affordable, well built, sounds great and has great specs.
