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. Review: AD18 from SMSL. Rocks! - This is my 2nd AD18 from SMSL.

I've heard earlier models did not function this way, but recently purchased units through Amazon should work. You'll need a 3.5 aux to rca cable for it to function I believe. I hooked up a powered sub to mine using the high level speaker inputs on the sub. **Q: What is the rated power output per channel at 8ohms, and the THD%?** A: The rated power output is 45w+45w @8ohm, THD + N = 0.04% **Q: When using the sub-out with a powered sub can the sub volume or levels be controlled via this unit?** A: Yes, and no. The SMSL's sub output level is variable, and raises/lowers in sync with the amps volume position, but you still have to set the master volume (for the sub) on the powered sub itself. I've got mine parked at about the 11 o'clock position, but results will vary depending on your setup. You will also need to find the crossover sweet spot on the subs low pass filter control. **Q: What is the frequency range of the input/output of the waveform?** A: It happens often ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pequeño pero poderoso *by J***B on 7 May 2022* 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.
