Hi Beoworld Forum. 

Can anybody explain to me how I should understand the ICEpower based Beolabs power ratings.

Look at the Beolab 7.2.

Power Consumption typical 20 W (standby 0.3 W) but the 6 built in ICEpower amplifiers delivers all together 750 W’s.

Input = Output plus heat loss

20 W = 750 W plus heat loss  ???

B&O don't seem to rate in RMS, sounds like peak 1ms to me. No way class D "makes" more power than it draws, unless they're defying physics😕

Granted class D is more efficient than AB or A; electronics laws still apply. Also no frggin way BL5 are 2.5kW continuous using 500va transfos!

Hi Davidr.

I fully agree.

Would like engineers from B&O to explain this mystery 😎
