Fohhn Amplifier D-4.1200

Fohhn Audio announces the upcoming release of its new multi-channel D-4.1200 digital amplifier.

The D-4.1200 is the latest in a series of powerful, 19-inch, DSP-controlled amplifiers that have been specially developed for demanding fixed installations and mobile applications.

Weighing just 11kg, the compact 4-channel D-4.1200 is nevertheless built to deliver robust and reliable performance capability. Featuring state-of-the-art Class D amplifier technology and Fohhn DSPs for the best possible sound quality, the D-4.1200 generates 4 x 1200W of power at 4 Ohms. An integral 4-in-6 matrix enables each input channel to be independently routed to the 4 powered and 2 auxiliary outputs. (The auxiliary outputs can also be used for controlling an additional standard amplifier.)


The D-4.1200 is equipped with extremely quiet fans and is designed to generate a minimal amount of heat when operational. Fohhn Mains Control constantly monitors the mains supply to the amplifier, interrupting it if the maximum permitted range is exceeded. By automatically switching on at the mains voltage zero crossing, the initial current input surge is also minimized on power-up.

As with all Fohhn products, system integration and control are key factors. The D-4.1200 features an integrated speaker database for all Fohhn loudspeaker types. Two separate Fohhn DSP engines are also included – one exclusively for speaker control and the other for user control of the onboard audio tools that include 10-band parametric EQ, delay, dynamics, crossover etc.

Channels can be directly edited via the amplifier’s blue 4-line front panel display, turning the D-4.1200 into a practical plug-and-play system for mobile applications. For larger installations, the amplifier can be remotely controlled and networked using Fohhn Audio Soft software and a laptop.

The D-4.1200 has an unlimited range of applications in venues that include concert halls, opera houses, theatres, churches and industrial settings.
