Hi everyone, I'm new to this forum and was needing some help.

In my living room I have some 5050 led light strips. 22 meters in total separated into 4×5-6m sections. The kit I got came with 3 power adapters and 6 rolls of 5m.

My first concer: the adapters are only 5A and I understand that the current rating for the strip is 1.2A/m?

One of the adapters was shot from the start so I had the 22m running from 2 adapters and one day one of them burnt out.

My plan is to have the strips reacting to music in which case I'd need a music controller and an amplifier as there's no music controllers able to handle 24A

Can someone explain to me if my thinking is correct and also the cable joining the strips to me looks insufficient too and having a browse online those cables are rated for about 2.5A.

What I need to know is what spec controller, amplifier and cables I need to have it working reliably and safely. My requirement is to have it synchronised too so it needs to run off one controller.

yes 6amp per 5metre i thought
and one power source per strip to avoid volt drop[ not a 12amp source to two end on strips]

Right idea big-all, but the OP wants it going to music, which means it needs an amp, or...........

yes more trying to say you need several 12v un connected electrically but connected control frequency wise
or a mains feed to them all with the sound control :dunno:

Not sure what you mean there, mains on LED strips could be interesting though :lol:

As an aside (That's why I posted this separately) there is more to multiple LED strips than what most folk would have thought in the first place. (Even me) I have learnt a lot over the past few weeks regarding LED strips and LED Pixels

i meant control the mains input to fluctuate the lighting in time with the sound
but as my brother showed me last year colour change works on minute voltage changes so sound control may only work on the 12v side :dunno:

LED strips operate on 12v, in theory you may be able to adjust the mains going into a power supply to change the LED strips, but in practice its not done.
As I said there is more to LED strips than most would think there is. Its also why the OP may need an amplifier.
