TAKE CONTROL
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 FILTERS
FIR Filtering gives
- Independent control of magnitude and phase.
- More detailed equalization.
- Optimization of frequency and power response.
STABLE DOWN TOÂ 2 OHMS
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.
ETHERNET X 2
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.
POWER FACTOR CORRECTION
Lets make this simple…. and call it PFC instead!
PFC not only aligns the AC voltage to the AC current, resulting in reduced heat and increased amplifier efficiency, but PFC also regulates to ensure smooth power delivery even with huge fluctuations in the AC supply.
BUILD YOUR SYSTEM
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.
