Fohhn Audio is to release the multichannel D-4.1200 digital amplifier, the latest in a series of powerful, 19-inch, DSP-controlled amplifiers developed for fixed installations and mobile applications.

Fohhn D-4.1200 power amplifierWeighing 11kg, the compact four-channel D-4.1200 uses class-D topology and Fohhn DSP, offering four channels of 1.2kW into 4Ω. An integral 4:6 matrix enables each input channel to be independently routed to the four powered and two 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 in operation. 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 minimised on power-up.

The D-4.1200 also 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 and crossover. Channels can be directly edited via the amplifier’s blue four-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 intended applications for the D-4.1200 include concert halls, opera houses, theatres, churches and industrial settings.
