    Sure Electronics AA-AB32321 2x125W Class D Audio Amplifier Board – IRS2092

     

    This 2 x 125 Watt Class D Audio Amplifier Board - IRS2092 integrates high performance IRS2092 supporting dual channel audio amplification. Both of channels are capable of outputting nominal power simultaneously and continuously. It’s suitable for amplifier enthusiasts or hobbyists to finish a complete amplifier system.

     

    This amplifier board also includes a myriad of protection features: over current, over/under voltage, DC output, and temperature protection circuits are built-in. A rather small footprint lends itself for use in space limited applications. Dimensions: 6" X 4.5"

    Dit was mijn eerste bestelling bij SoundImports, zeker niet de laatste. Spullen supersnel in huis, grote plus voor mij is de klantenservice: ik had een probleempje gemeld per email. Zeer snel reactie ontvangen, er werd meegedacht, gewoon heel goed en professioneel. 5 sterren!

    De versterker module: niets op aan te merken. PCB ziet er netjes uit, geen vuiligheid oid. Plug & Play; + en - 45 tot 50 V aansluiten, bron en speakers en het speelt. Nog niet kritisch geluisterd, maar vind 'm verbazingwekkend goed (voor die prijs). Prijs/kwaliteit vind ik m 5 sterren zeker waard.

    This device works very well it can produce transient, details and grain I like from my diy dipole speaker. Comparing with tpa3116 solutions, there’s a better control of diaphragm motion.
    The major issue is related to the gain: too much gain can emphathize noise coming from the sources. I solved the issue by replacing the 3k input resistor with a 6k one, reducing the gain to 26dB: more than enough for my setup. I’m planning to replace or remove completely the input caps to reduce distortion.
