PSSO QCA-6400 4-Channel SMPS Amplifier

4-channel PA Amplifiers with Integrated SMPS The 4-channel PA amplifiers of the QCA series offer ultra-high output power paired with a low weight and small overall height. The amplifiers use a patented second-generation Class I output circuitry which combines the high efficiency off Class D and the sound quality of Class A. Featuring a modern switch-mode power supply, the amplifiers provide up to 10 kW peak power and weigh less than 16 kg. This makes the series particularly attractive for mobile applications. The amplifiers can be used flexibly in stereo operation, parallel operation or in mono bridge operation. Extensive protective circuits will protect the amplifiers and the speakers connected.PA amplifier with SMPS, 4 x 1600 W / 2 ohms, 4 x 1400 W / 4 ohms4-channel PA amplifier with class I circuitry 4 x 1400 W/4 ohmsLow weight and height due to integrated switch mode power supplyReliable power amp with high impulse stability for a wide range of applications (e.g. compact PAs, multi-way PAs, international concerts)Speaker switch-on delay3 operating modes can be selected (stereo, parallel or bridged)4 level controls for precise level adjustmentInput sensitivity adjustableLED VU meter and LEDs for activated protective circuit (protect), overload (clip), and signal per channelComplete protection set against short-circuit, overheat, clipping, overload, DC voltage and VHF signalsHighly efficient front-to-rear air routingElectronically balanced inputs via XLR mounting jacks, with XLR feed-through outputsSpeaker outputs via lockable Speaker plugsRugged steel chassis with aluminum front panelRack installation with 2 unitsNeutrik Speakon outputsHousing design: (19") 48.3 cm rack installation 2 U
