DP-4100F

  • 4 channels
  • 8 Ohm 4 x 1000 W
  • 4 Ohm 4 x 1700 W
  • 2 Ohm 4 x 2890 W
  • 16 Ohm Bridged 2 x 2000 W
  • 8 Ohm Bridged 2 x 3400 W

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
 

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 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-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.


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.

Good for my collection.
Format: Hardcover
This was another quick and entertaining read. This instalment wasn't as enjoyable as some of the other books but it was still good. I'm glad to have it in my collection.

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.
