PSSO QCA-6400 4-kanálový SMPS zesilovač, 4x 2100 W

4-channel PA amplifier with class I circuitry . 4 x 1400 W/4 ohms. Low weight and height due to integrated switch mode power supply. Reliable power amp with high impulse stability for a wide range of applications (e.g. compact PAs, multi-way PAs, international concerts). Speaker switch-on delay. 3 operating modes can be selected (stereo, parallel or bridged). 4 level controls for precise level adjustment. Input sensitivity adjustable. LED VU meter and LEDs for activated protective circuit (protect), overload (clip), and signal per channel. Complete protection set against short-circuit, overheat, clipping, overload, DC voltage and VHF signals. Highly efficient front-to-rear air routing. Electronically balanced inputs via XLR mounting jacks, with XLR feed-through outputs. Speaker outputs via lockable Speaker plugs. Rugged steel chassis with aluminum front panel. Rack installation with 2 units.
