Perfectly adapted amplifiers and DSP technology.
The Fohhn® D-2.1500 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-2.1500 is extremely lightweight (only 10.1 kg), 2 channel operation, 2x 1500 W / 4 ohms, 2x 900 W / 8 ohms, Fohhn Audio DSP, with blue 4-line front display, operation or remote control via a laptop.
Sound quality. Reliability. Intelligent control.
>Fohhn® Mains Control – the integrated mains supply monitoring system<
During use, the supply to the amplifier is constantly monitored. If at any time it exceeds the maximum permitted range (180-255 VAC), the supply will be interrupted. During power up it also minimizes the input surge current by switching on at the mains voltage zero crossing.
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-2.1500 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-2.1500 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.
