Tip & How-To about Dynaudio Acoustics BM6A MK II Active Studio Monitor

Dynaudio BM - Power from 110V to 240V or 240V to 110V

Hi Guys,

This is what I have learnt the hardway so wanted to share it with everyone who wants to get his Dynaudio Speakers converted from 240V to 110V or 110V to 240V.

I actually requested many forums including Dynaudio Support as I bought mine from US and they were 110V, I wanted to use it in my Country which has 240V standard, What these guys suggested me was to order the whole AMP Modules for the speakers if I want to have them work in my country. In other words it was a solution of $350 per module totals to $700.

Shame on them as I opened the speakers myself and found a small jumper wire hooked up on the connections marked 110V and there were other connectors marked with 220V and 240V.
All I did was just took out the jumper from 110 and inserted it in 240V connectors!!
Thats about it!
So guys forget these mean techiz at Dynaudio and use my experiene to solve your problem :-)

Rockola 470. How can I convert my 240v 50hz to 110v 60hz to supply my jukebox?

2 choices: replace power supply transformer or replace motor to get the right speed and the right sound pitch.

connected alesis sr16 with alesis 110v power supply.to 240v mains...........briefly powered up and then nothing. Have I "fried" the adapter or the sr16?

Look carefully at the adaptor and see if it takes any voltage besides 110 (it will say in very tiny print, you will need a magnifying glass). if it does NOT say 220V or 240V then you friend the adaptor. Get another adaptor - most are "dual" voltage meaning they run in the U.S. or overseas.

Also check for "polarity" (which part of your plug is + or - ).

my monitor is styill for working but the tweeter dont make any sound. i think its blowed up, is there a fuse a something that could be replaced in the amp?

no fuse in there unfortunately.

The problem could either be a blown tweeter (but that would likely cause distortion rather than silence) or a fault with the amp or crossover. Often it seems a relay is at fault in these instances with dynaudio monitors. In any case, unless you have considerable electronics knowledge (which I think it's fair to assume you don't ?) you won't be able to fix em yourself. Give dynaudio an email or call - they're helpful.

Hi, I own the Dynaudio BM6A acoustics monitors & I want to know if there is a circuit breaker system inside the monitors, for surge protection? The reason I ask is because I have no power conditioner for my rig, and I am afraid about the monitors the most. thanks a lot for the servise! Mauritzio

If an internal circuit breaker pops, something has failed. Even surge protectors do little to protect stuff unless they are high level types with filtering. Key thing: ALL your interconnected equipment MUST be powered from the SAME receptacle or power conditioner. Using multiple outlets can allow building "ground bounce" to rupture sensitive input circuits. Use of balanced lines avoids noise in systems.
