(full neodymium)
High-power fullrange system, 12“/1,4“ CD neodym., 80°x50°, with integral DSP amplifier for connection a passive X-Top, or Sub. 2x 1000 watts / 8 ohms, Fohhn Audio DSP, networkable/ remote control. Multifunctional housing also suitable for monitor operation, mounting devices for U-bracket VXT-3.
State-of-the-art amplifier technology developed to meet the most demanding requirements for audio quality and reliability.
Our active speaker systems are equipped with state-of-the-art CLASS D technology and were developed to meet the most demanding requirements for audio quality and reliability in fixed installations and mobile applications. The main advantages of the CLASS D amplifiers are the low weight and compact dimensions, outstanding sound quality and a high degree of efficiency that minimises heat development inside the amplifiers considerably compared to conventional analogue amplifiers. The amplifiers require minimal cooling and always operate reliably as a result.
Speaker Management System.
Specifications for all types of Fohhn speakers are stored in a speaker database. An algorithm especially developped by Fohhn® guarantees a balanced sound and maximum operation reliability at all volume levels.
Easy to operate.
A control panel with a blue, four-line LCD display is integrated in Fohhn active systems, amplifiers and controllers so that users can adjust and view the DSP functions on the respective audio device.
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.
