Sinewave 50W+200W CLASS D ACTIVE SPEAKER AMPLIFIER MODULE

Hey,

Anyone have experience with this product?

Buy 250W ACTIVE SPEAKER CLASS D MODULE, 4 TYPE FIXED EQ, ACTIVE SPEAKER, 50W+200W CLASS D ACTIVE SPEAKER AMPLIFIER MODULE at Aliexpress.com

Looks like it could be an affordable alternative to the Hypex AS2.100.

I've requested documentation since the website does not provide any details.

It looks to me like they somehow have put all imaginable functions in this module. If i understand correctly, it is not stereo but only 1x200 W and 1x 50 w for public speakers and sales events. Do you want to have MP3 player at the back of both of your speakers ? I am affraid that the sound quality will be far from the Hypex modules. Yes it is cheap, but you have to buy 10 of these to test it

I believe that product is from fellow forum member "authlxl". You could try to PM him if you have any questions.

Received the documentation. It appears that the crossover frequency is fixed at 1k and the EQ consists of fixed selections. No evidence of a DSP. Oh well.
