Niet Meer Leverbaar - Fohhn D-4.750, DSP Amplifier, 4x750W, 4 ohms 2x DSP output, Display, Audio DSP remote control
Perfectly adapted amplifiers and DSP technology.
The Fohhn® D-4.750 DSP-controlled CLASS D amplifier was developed, to fulfil the most demanding requirements concerning sound quality and reliability. Fohhn DSP amplifiers guarantee an excellent sound quality, maximum reliability and offer a host of possibilities for adapt your sound system to various room acoustics. The D-4.750 is extremely lightweight (only 11.1 kg) with blue 4-line front display, operation or remote control via a laptop. The D-4.750 CLASS D with 4x 750 W / 4 ohms, 4x 390 W / 8 ohms is fitted with the new Fohhn Audio DSPs as well as 2 DSP Aux outputs for controlling an additional standard amplifier.
Sound quality. Reliability. Intelligent control.
- 4 input channels
- 4 amplifier outputs, each with 750W at 4 ohms (output channels 1-4)
- 2 DSP Aux outputs (output channel 5+6)
- State-of-the-art CLASS D amplifier technology
- 5 premium audio tools such as Parametric EQ are integrated
- Integral speaker database for maximum operating reliability
- Remote monitoring/operation, network-compatible
- Minimal heat development, extremely quiet fans
Each of the 4 input channels can be routed to the 4 amplifier outputs (1-4) and Aux outputs (5-6). Each channel can be edited separately or in combination with other channels.
2 DSP Aux outputs
The D-4.750 has 2 utputs “Aux5” and “Aux6” for connecting an external amplifier. Knowing the data (amplification, maximum output voltage) of your D-4.750 amplifier is essential to protect your speakers. The D-4.750 gives you the option of storing and accessing the performance data of up to 100 amplifiers, which can be viewed on the display, edited if necessary and then saved under a different name. The stored data can then be loaded to output channels Aux5 and Aux6. You can of course assign a separate amplifier to each output channel. Once you have loaded an amplifier preset, the performance and speaker data is evaluated and the multiband limiter on the D-4.750 is preset automatically.
Plug & Play
With remarkable reductions in generated heat and an incredibly low weight and compact dimensions combined with characteristically high levels of output power, we recommend this new Class D DSP amplifier for an unlimited range of applications, including AV & media, concerts, opera houses, theatres, churches, cinemas, theme parks, television studios, delay lines, stage monitoring and industrial applications. Rapid DSP access via the 4-line display transforms a mobile application into a simple, reliable Plug&Play system. The D-4.750 is extremely quiet thanks to temperature-controlled ventilators and an adjustable noisgate!
The new amplifiers save you having to use/adapt external DSPs, EQs and crossovers as well as using cables, and in smaller installations, you can also realise your projects quickly and reliably with a comparatively simple microphone mixer.
Remote control / Remote monitoring
The system´s network compatibility and remote control options via a laptop provide you with assistance while you work. You also have the option of linking the D-4.750 to a media control system.
The Fohhn Audio DSP.
Dual DSP power for excellent sound quality and optimal reliability. Integrated Fohhn DSP technology offers a host of possibilities for implementing your sound concepts. The equipment includes two separate stereo DSP engines and integrated speaker database for all Fohhn speaker types, which is what makes our amplifiers so unique. The speaker database is based on an algorithm specially developed for each speaker, which protects bass, mid and high frequency drivers in all performance classes and guarantees outstanding sound and maximum operational reliability.
5 professional audio devices offer valuable benefits on an every day working level: 10-band parametric EQ, delay, compressor/limiter, noise gate and crossover allow the user to adapt the audio system perfectly to sound requirements, room acoustics or personal preferences. Cable faults, cumber some rack cabinets and tangled cablesare a thing of the past. The integrated technology reduces the weight and dimensions of the unit and guarantees stress-free operation. In addition, the operating status display gives you complete control in monitoring the temperature and operating time.
User software, USB adapter, WLAN adapter.
Perfectly adapted amplifiers and DSP power for all your mobile and fixed installation projects with Fohhn speaker systems.
