Amplifier with switching power supply 4 x 1600 Wrms (4 ohms) - QCA-6400 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.

  • 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
  • Neutrik Speakon outputs
  • Housing design: (19") 48.3 cm rack installation 2 U
