Questions and Answers

I Have this working OK on USB, and Bluetooth from Iphone, but I can't get it to work from either the front or rear AUX connections. Am i missing something in the controls, or have I got a defective one?

It took me forever to figure it out. I thought it was only my unit, but I see it's not the case, and it's clearly a design defect. You need to have Bluetooth playing, press the Play-Pause button, switch to Aux with the M button, then press Play. Usually it starts then playing the Aux-RCA source. You can press Play-Pause and it mutes Aux, then again to restore the sound. Once you turn it off, you need to repeat the process to select Aux. Basically Aux cannot be used unless you have a Bth source first (I think you can play from USB-TF also first)

i want and power supply

After 1 week of home use one of the channels gives constant noise when playing which is annoying. Is the amplifier broken?

Arrived fast and well packed. First seemed a problem, as just a small green light flashed for a fraction of a second by pushing volume control. Nothing else. May be because of a less powerfull power supply (12V 1A). The volume meter has no start/stop position, you can turn it around. Then when inserted a pendrive suddenly switched on, 2 strong green lights appears with the LED panel. After that everithing worked fine, all input works as it must be. I used with a Roadstar 4Ohm 24W sound box pair as seen on photos. I have ordered a 24V 5Apower supply to try it with my 100W sound box pair (using it with a 180W amplifier now). But I am quite satisfied with my 24W boxes, I will use this tiny box with those.

Very satisfied. Shipping in reasonable time from Belgium, Compact and well-made product. The sound is surprisingly balanced with powerful but balanced bass, well-present and balanced mediums, crystal highs without being ringing and annoying. Although driven by a 24V 5A power supply the output power is certainly not 50W per channel but less than half (they will be ear 20W channel) that however, even if pushed to high volumes, does not denote important distortion, on the contrary. Currently tested only with aux and with bluetooth; the latter is easy to match and the connection is stable in the range of about 10m. I definitely recommend it to sound a medium - sized (4mx4m) environment. The finishes are good in general, very good considering the price. Last remark: even at high volume the little monster does not warm. Pro Economical Excellent sound quality Finishes Versatile Dimensions contained Against Volume lower than declared

Sound quality is excellent and the amplifier is easy to use. Connects to my devices quickly and without problemes every time. Construction is good, but 2x50W seems a bit optimistic, considering the amplier ICs are only cooled by the ciruit board. All in all a very nice amplifier with a stunningly low price. I just bought a second one…

Excellent amplifier, and not only. High quality and quality sound! I recommend it!! It'd be the best thing if it had control!.

Super small toy with great performance. Small and very light, the power supply is bigger and heavier. Speaker connector is a source of confidence, the 5.0 BT + point. What is missing is a headphone jack, dimming the display, and the light around the volume control could be dimmer. The sound is still a bit "digital" to be introduced.

Nice unit. Arrived in Canada earlier than expected. Nice wide voltage input. I'm using a 20 volt power supply from an old printer and the amplifier works great. Bluetooth setup was fast and easy. Binding posts for speaker wires are good quality. Would definitely buy again.

A termék kis késéssel megjött (korona vírus miatt). A 2x50W túlzás, de szépen behangosít egy normál szobát. Mivel nincs hangszínszabályozó beépítve, így a basszusokat normál, 2.0 helyzetben hiányolom. Célszerű Equalisert telepíteni a mobil telefonra, és ott lehet hangszínt állítani. Kipróbáltam egy passzív 2.1 felállásban (Infinity passiv-subwoofer 100W +2X Magnat 20W házimozi front hangfal. Így már szép telt a hangja. Kicsi, szép, célnak megfelelő. Első itteni rendelésem volt, most már bátrabb lettem

Excellent stereo amplifier. The quality / price ratio I find is impeccable. Beautiful aesthetically and robust, its materials are very good. Personally I use it almost exclusively with bluetooth input and I can say that it has never lost the connection remaining perfectly hooked to the source.

excellent performance beyond my expectations. Very good sound quality.No hissing sound at all. Bass response was enough for me. channel separation was good. I found there is thermal protection also. very much satisfied.
