  • All-purpose audio

    posted by hatallica

    * USB and SD inputs - listen to hours of your own music.* Audio Line input - I connected my TV audio output.* FM radio includes auto-tuning feature* 4 speaker outputs allows me to use the old speakers from my broken bookshelf stereo.
    A few times, the radio did not work when I switched modes. Turned off/on and it was ok.Power supply - sku.56426 is what I am using right now. It is only 12V, 2A, but that is enough power for typical TV or radio audio. I was using a supply with higher current rating, but had an audible buzz.
    I used this to replace all of the audio functions normally in a stereo costing 5x or 10x. Ok, you need to provide your own speakers. Audio is not premium, but not bad, either.

    Small and powerful! This small device is able to replace a micro system. Their sound is loud and clear, has memory card reader and USB Pen Drive on. His case is a aluminum heatsink, do not worry even connected for long.
    Could have cds player, would be perfect and complete. plugged the unit into two speakers from my old micro system, have more space and the same sound!
    Tired of your computer system? find more convenient than the thumb drive keep changing cds? Want to listen to music from your memory card into a sound? Buy this product!!
  • Good class-D amp.

    -Stay lukewarm at low level (<5watt) and around 40°C for 2x15watt approximately.-No on/off "pop" at all.-Good sound quality.-Small and compact board, easy to integrate.-Great voltage range operation. -Very low humming (at least with a 24v power supply and 90db/w/1m speakers)
    I use it right now with a generic 24V/5A switched-mode power supply ,a 5€ USB sound-card and a 50Kohm logarithmic potentiometer. Sound is very good on my cheap 6Ohms Jamo S406. After a short break-in (2/3 hours) the bass are solid, treble/medium are clean. I didn't test it at high level but I think its powerful enough for a small party in the living room :)
    Definitely a good price/performance ratio. I would recommend it for someone who want a good sounding inexpensive system. Thanks DX for this very affordable chinese DIY audio board, they are good sounding and fun to play with. ps: Sorry for my mistakes, english is not my native language.
