DP-F Series

  • Huge Class D power in a 1U rack
  • 4 discrete amplification channels
  • Internal DSP and computer control
  • Stable down to 2 Ω. Drive multiple speakers or line array elements
  • FIR filtering with 512 taps
  • 90 V to 260 V AC working voltage
  • Ethernet Network Connectors x 2
  • 70 V / 100 V compatible models



Harnessing the power of the internal DSP

The supplied editing software gives a practical overview of all system parameters and DSP features within the DP-F amplifier.

It is simple to monitor and edit the DP-F remotely.



FIR Filtering gives 

  • Independent control of magnitude and phase. 
  • More detailed equalisation.
  • Optimization of frequency and power response.


Huge output power and stable down to 2 Ohms

The power output figures of DP-F series are staggering. The rated power outputs are measured at THD = 1%, continuous sinusoidal 1 KHz with each channel working simultaneously. 

DP-F amps are also stable down to 2 Ohms. This allows for multiple 8 Ω or 16 Ω speakers to be driven with extreme power.


Control is via the Ethernet network connectors on the front.

With the supplied control software all parameters can be edited and all performance functions can be remotely monitored.


DP-F and DP-N amps are made for your big line array!

With just 3 pcs of DP-4100F or DP-4100N……massive systems can be created.

70 V / 100 V READY

In this high impedance system example, the DP-2200F can drive up to 100 pcs of i8T loudspeakers.This configuration can also drive LESS than 100 pcs of i8T.  Any number between 2 or 100 !

When switched to 100 V mode, DP-N (F) models have Peak Limiter and RMS Limiters set automatically.  Only the HPF needs setting in the EQ section.


Important : Before connecting the load to the amplifier, first measure the line impedance with an impedance bridge (a simple low-cost unit is adequate). If the load impedance is too low, the power amplifier will be loaded down and may overheat or distort. It’s a myth that you can connect an unlimited number of speakers to a 100 V or 70 V line.   If the load impedance measures it’s lower than the amplifier minimum operative impedance, re-tap all the speakers at the next-lower power tap.  This raises the load impedance. Measure again.
