Sad sam se setio, radili su bench test tog pojacala u engleskoj. Evo sta kazu.
Got 1 yesterday..I bench it! 650W per channel, both driven at 1Khz into 4 ohms...1275W 1 channel driven into 4 ohms...Lack in the power supply! Not able to test it into 2 ohms, protect trip at about 400 watts! At 650 watts per channel, it come really hot in less than 5 minutes! To be fair, I have redoo the test with burst signal at 1 Khz, 20ms signal, 40ms no signal and can get nearly 1300 watts per channel, both driven. This test is more like music signal. I was able to bench it for 30 minute with ''normal'' heat, but I stop it to not burn it. Freq response is 25Hz to 18 000Hz flat, but totaly unable to make power test under 50Hz, lot of power supply ripple. Have to mentione too that it's a class d amplifier, output coil are under amplifier heat sink. The one I got is with 'squirrel' blower, not the small fans as seen in first post picture. To be honnest, it sound incredibly 'cold' (QSC sound!). Class d ripple is a bit hight, about 4V HF sine wave on output. Another thing very important: These amp are full bridge design with 60VDC on each speaker wire. If you buy one, just be sure to have separate wire NOT CONNECTED TO ANYTHING going to speaker. Of course, because of this amp is not bridgeable...
So in conclusion...Nice toy, maybe good for top or monitoring, but definitavely not good to drive sub stack, except maybe in 8 ohms...And with proper limiter/processing to not overstress it...For sure I will stay with our PowerSoft and D-Amp amplifier for our main rig!
A evo i slicica jedna druga koja mnogo vise lici na D3400 :-)
