This shit all connected soldered right all power supply checked even shurupoverta eventually played very little quieter the phone and plays with stops
24 V works otlino
How about sound quality? There is a drone, shypeniya, flooding, etc. TP. Is there any complete silence in the columns?
I don't know why people write about jokes. If you turn off the silence is dead. The hissing passes with the advanced device which you connect.
What to do, just lit, but no sound. Likely to marry, and how to fix it?
Worked, and the led died, but there is no sound when connecting, there is a click, but it does not pluck..
Which limits the dynamics. I have only 3 W Bole Menie sing. Food that 12 that 24 difference not felt
Connected the column 15 W. Dolbit clearly. Power supply 12 V 2 amps.
can I used 15w×4 pic speaker.how much DC volts in this board
Connected 12 V but the bulb is on and there is no sound
Hello, technicians. I want to power 5 V 2a from the PSU through the boost converter. How much then v turns out? Who tried, write the result, still I will power up two columns of 15 W.
Well, look at this: 2 channels on 30-it's already 60 watts. Now 60 W divide into 12 V. How many ampere need? Right, 5A... It's at the maximum. At a minimum it is necessary at least 3. but not less! And from 12 volts!
As connect power?
From the 12v battery. Purely plays does not hisses. As soon as the block of cyplia hisses and strongly.
But I have a column it is 250 Watts and the other 45 watts this amplifier pulls these speakers?
The guys are leaking at the resistance of the dynamics of 4ohm and below. At 8 ohms plays perfectly. Checked when powered from 8 V to 24 V on a load of 8 ohms works wonderful.
Put the amplifier for speakers of 5 W, all well lit and no sound, sometimes bubbling. Everything is connected properly. What advice can give, or a marriage with Ends??
5Вт на колонку?! 😄 А зачем же ты его заказывал? Он же по 30-хе на канал! Спалишь свои динамики...
The board works but at full volume the speakers stop playing and start to click who knows why
There is not enough power supply. The power of the speakers here is not at all.
