Suitable for professional live sound reinforcement or fixed installations, the top of the range 4-channel DP-4120 delivers extreme power from a light weight design.

Its advanced switch mode power supply and super-efficient Class D topology delivers high power with low distortion.
With 4 discrete channels and multiple operating modes its simple to configure into the most complex of installations or touring rigs.

DP series are also stable all the way down to 2Ω.  This means they will drive multiple 8Ω or 16Ω loudspeakers.

Key Features

  • Top of the DP series lineup
  • Super light weight - Only 12.3kg
  • 4 channel configuration
  • Power Output 8Ω : 4 x 1200w
  • 2 x 4080w@8Ω BTL.
  • Ultra-quiet variable speed fans 
  • Advanced protection circuitry
  • Class D topology
  • Stable at 2Ω.  Drive multiple 8Ω or 16Ω loudspeakers
Internally, a full suite of protection circuitry includes thermal, over-current, DC, short circuit protect and power on/off mute. This level of protection ensures long term system reliability and peace of mind should the worst ever happen.


Front panel LEDs also keep the sound engineer well informed with fault, peak and signal LEDs.


The variable speed fans keep the amplifier rack quiet when not in use - and cool while its running at high volume.
The DP Series feature stereo, bridge and mono modes. Use in bridge mode with an individual high-powered subwoofer or use a single DP to power your whole sound system equally.


Mono mode saves external cabling by splitting a single input to feed both channels of the amplifier.


In addition, gains can easily be controlled by the rear panel gain switch. This allows for installation into almost any rig or venue.


The DP-4120 features XLR inputs with a maximum input level of +22dBu allowing for integration with any typical professional audio system.
The 1U design allows for powerful systems to be configured in extremely confined spaces. In the tour rack or in the amp room, DP delivers reliable power from a small box.


Lightweight, powerful and portable. Its that simple!
Stable down to 2 ohms
Need to drive multiple loudspeakers in a larger system?


DP series amplifiers are stable all the way down to 2Ω allowing for daisy-chaining of 8Ω or 16Ω loudspeakers.
