Key Features:
  • Class AB power amplifier
  • Delivers 2x 250W into 4Ω
  • Full range frequency response
  • Switchable ground lift & bridge/stereo mode
  • Designed and engineered in Germany

The DJ500 is a powerful, full-featured Class AB power amplifier with an output of 250W per channel @ 4 ohms and 500W in switchable bridge mode. It is especially suitable for mobile use by DJs and smaller bands and in permanent installations.

The DJ500 has extensive protection circuitry and a power-on delay. The half perforated front panel and a low-noise fan keep the amp cool. XLR and stereo TRS sockets are used as inputs and Speakon-compatible sockets and heavy-duty screw terminals as outputs. A ground lift switch helps eliminate ground loop hum. LEDs on the front panel next to the easy-grip volume controls indicate functional status, overloading, and triggering of the protection circuit.

The DJ500 functions in the entire frequency range of 20Hz – 20kHz with extremely high dependability, dynamics, and impulse fidelity.
