Mackie Designs has implemented a unique "Vacuum Tube" philosophy for amplifiers designed for mid and high-frequency reproduction. The FUSSION 3000 features two Trans-Fet amplifiers, one for the midrange driver and a modified version for the high-frequency compression driver. Our Trans-Fet technology combines a very simple Class AB design topology with special transformers fitted on the amplifier outputs, that assists in eliminating intermodulation distortion by-products. This type of design emulates the celebrated warmth and transparency of vacuum tube amps. The result is clear, and accurate reproduction..

The FUSSION 3000 delivers deep, quick bass through the use of four 12-inch high output woofers. Each 12-inch woofer handles 350 watts RMS long term. Placing four devices within the cabinet allows the FUSSION 3000 to produce very deep, precise reproduction of low frequencies. Using four 12-inch woofers allows low frequency reproduction to be extremely "quick" compared to other designs. The low frequency amplifier module is an excellent example of the efficiency of active designs. This amplifier uses a high-efficiency, high-current topology to produce 1500 watts of power from a module the size of a single sheet of paper.

Frequency response of the FUSSION 3000 is linear between 55Hz and 18KHz. The system processor provides complete system management of all electronic and acoustic functions including electronic active crossover, electronic phase alignment, electronic time correction, electronic equalization and complete amplifier and component protection. Because it is designed to deliver very high output levels (133dB peak-full range) and wide dispersion, the system can only be line-arrayed with other FUSSION 3000 cabinets. The system's wide dispersion characteristics do not allow it to be used in large arrays.

FUSSION 3000 is the first professional speaker system to create a completely ideal union between transducers and amplifiers. To ensure long-term reliability and performance, the amplifier cards and processor are mounted to a huge heat sink eliminating the need for fans, dramatically extending life expectancy and eliminating maintenance cycles. An easily-accessible rear input and control panel offers substantial signal routing flexibility. All audio connections are via XLR connectors, including a main input with a loop-through output for connection to other enclosures. A Full Range/High Pass switch allows the FUSSION 3000 to be operated full range or above 85Hz only. A SUB-OUT connector allows simple connection to the Fussion 1800AS/1800S active subwoofer system. The SUB-OUT signal is low-passed below 85Hz and also contains the limiting and protection circuitry for the active subs. For sound reinforcement situations where "fill" speakers are needed, there is a Fill-Out connector with level and (0°-180°) phase controls. Mackie's FUSSION 3000 can run on 115V AC or 230V AC single phase. The system features soft-start circuitry that eliminates "pops" and precisely controls AC in-rush current surges.
