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-N amplifier.
It is simple to monitor and edit the DP-N remotely.
REDUNDANCY
DP series amps get used in ‘mission critical’ environments. Therefore the ‘auto’ mode has been built in to deliver redundancy capability.
Set the input to ‘Auto’ and the input will change, should a problem happen with external connections.
(Use of an internal delay is advised to compensate for any switch timing and latency issues)
FIR FILTERS
FIR Filtering gives
- Independent control of magnitude and phase.
- More detailed equalisation.
- Optimization of frequency and power response.
STABLE DOWN TO 2 OHMS Huge output power and stable down to 2 Ohms
The power output figures of DP-N series are staggering.The rated power outputs are measured at THD = 1%, continuous sinusoidal 1 KHz with each channel working simultaneously.
DP-N amps are also stable down to 2 Ohms. This allows for multiple 8 Ω or 16 Ω speakers to be driven with extreme power.
DANTE ™
Using the Ultimo 4×4 chipset, DP-N amps easily join any Dante ™ ecosystem.
- Digital audio connectivity of up to 96 KHz
- Remote, network control.
BUILD YOUR SYSTEM
DP-N amps are made for your big line array!
With just 3 pcs of DP-4100N……massive systems can be created.
70 V / 100 V READY
In this high impedance system example, the DP-2200N 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.
