IRS2092S 500W Mono Channel Digital Amplifier Class D HIFI Power Amp Board With FAN
A part of the review has been auto-translated.
As small as it is, this thing makes a lot of noise. Take care not to blow up your speakers! You need a double (+ and -) power supply, at least +50V and -50V. As for the connections, they are a bit unclear but here they are. Take the pcb in front of you with the fan on the left and the blue connector on the right (see attached photo). The connections of the blue connector from top to bottom: speaker + speaker - +60V GND -60V The connections of the white connector from top to bottom: input ground input positive
Can a connection circuit? Which is the audio input output and power supply? On a picture please.
Banggood send me a second amp when the first did not work. Now I get 200 Watt from 2 * 55 Volts, efficiency better than 80 %. Wow!
Perfect!!!: So powerful. The only thing is you need a transformer like + 50v AND -50v, or two transformers, because you need the + and the - 50 v. Really I´m usinga 52v +- transformer. After some hours they become noisy. This is because of these small fans. The fan is pure trash, so start to loose the equilibrium just from the first moment you turn on the amplifier. The fan start to touch the alluminium dissipator, and the noise become a part of the sound circuit. So the solution is tu remove the trashy fan and to install another one (external). And voilà: a powerful perfect small power amp. Blessings from Spain,. probably the best country in the world ;-) ;-)
Wow !! This little amp kicks ass!! It will blow your speakers if you are not careful. Amaizing power pure digital 500W RMS !! recommended power supply +60v 0 -60v Very powerful clear crisp sound and solid bass. good value for money
Deliver hj. I thought it was too small to generate 500 whats. But I will provide the source and remove my doubt.
Yo lo alimente con una fuente de +- 60 VDC@10A que recicle de un AVR Onkio funciona bien. Le inyecte señal con una mixer behringer al parecer tiene buena sensibilidad. Lo conecte a un bafle JBL JRX 215 y lo mueve al 100. PROS: - Buena potencia - Buena definición - Conexiones mínimas - tamaño compacto - Buena protección térmica CONTRAS: - La resistencia de 10 ohms que esta cerca de la salida saca humo si no tiene una bocina conectada a la salida. - El inductor se calienta demasiado. - Al conectar con otras bocinas sin crossover pasivo, los mosfet se calientan y se apaga el amplificador.
My product is not working
took.more arrived.vlw
I couldn't make it work. Apparently everything's fine, 60v asymmetrical feed, ok input, speakers ok.. It keeps swaying, it works a bit and for the sound, the fan goes on (or not because when I take it out of the socket it stays on for a few seconds, so it's not sure).. Did anyone there have that problem and get it to work? Ahh in an attempt like that to tidy up, I moved that trimpot or that train that looks like one and, I'm not sure that's why, but I ended up burning, by the way, by toasting a 10" speaker, if I'm not mistaken for 250w, A box with a bugle and tweeter, which continued to sound, I didn't move anymore after the accident, but finding out something else I come back here to update the account
