Pros:
Stereo single-ended configuration Po output power RL = 3 ?; THD = 10 %; VP = ±27 V - 110 W; RL = 4 ?; THD = 10 %; VP = ±27 V - 86 W Mono bridge-tied load configuration Po output power RL = 6 ?; THD = 10 %; VP = ±27 V - 210 - W
Cons:
It comes with output filter inductivity of 22 mH and capacitator of 470 nF. Those results in engaging of the low load impedance protection at high power on RL = 4 ? .
Other:
The output filter values in Stereo single ended mode should be: RL L C 2 ? 10 mH 1 mF 4 ? 22 mH 680 nF 6 ? 33 mH 470 nF 8 ? 47 mH 330 nF
Bottomline:
Perfect small amplifier with a reasonable price
