All user reviews for the JCB XPP 4200

"I use this amp for 1 month.
-I bought because it has a good price and quality that is being protected.

-Powers: 2X300W RMS into 4-Ohm and 8 Ohm RMS 2X200W.
-Bandwidth: 10Hz-De 20'000Hz with trs bonnne restitution in the Lower.
Taut-Harmonic Distortion (THD): <0.1%
-Damping Factor (Damping Factor): -350 / 1 For the XPP 4200 and 200 / 1 for the XPP 3200. (The damping factor is the ability of the amplifier include the movement of the Boomers, the more important over the amplifier can keep the CONTRL).
-Cooling: Variable Speed ​​Fan-Major, trs trs Noisy but effective full power.
-Protection:-All protections (Soft Start, Overload, Overheating (80C), input level too high, voltage and short circuit), but not according to Bridge.
-Display: 2 LED Clip (1 per channel), a blue LED in the center of Power and a powerful trs Led Orange Protect.
Good-Finish, Rackable 19 "2U (Note there arati at the top and on both cts).

Ds 1-day problem: Out-of the packaging, the fan is not running! Even when I did walk the entire APRS Amp noon with the same clip peaks, heating it very well but it did not rsist and grill (Under 4 Ohm when same). I had ramen shop, the APRS ascultation technitien (The Amp works but fan HS), it gave me a new one against t chang (Exposure):-The fan is Bruille trs, progressive ventilation works well.
