INTRODUCTION
Thank you for choosing Mackie Designs’
active sound reinforcement speaker systems.
The FUSSION 3000 is a full-range, me-
dium throw, active loudspeaker system
capable of extremely high sound pressure
levels and wide dispersion. With almost
2000 watts of low-distortion built-in power,
the FUSSION 3000s are ideal for large
sound reinforcement systems that require
precise reproduction of transients, high lev-
els of intelligibility, and compact size.
The FUSSION 3000 features specially
designed, high-output transducers includ-
ing a special eight inch, horn-loaded
mid-range that allows the FUSSION 3000
to generate extremely low distortion
(< 0.05%) at full power. The mid-range
operates between the frequencies of 500
and 2500 Hz , eliminating the placement of
a crossover point in the middle of the criti-
cal voice frequency range. The result is a
super smooth phase and power response
that delivers extraordinary intelligibility at
extreme output levels. Frequencies above
2500 Hz are reproduced by a 3˝ titanium
diaphragm compression driver mounted to
a 80 x 60 degree horn with a 1.4˝ exit
throat. The FUSSION 3000 delivers deep
bass through the use of four 12˝ high-
output woofers.
The FUSSION 3000 frequency response
is absolutely flat between 55Hz and 18kHz.
The system controller provides complete
system management of all electronic and
acoustic functions including electronic ac-
tive crossover, electronic phase alignment,
electronic time correction, electronic equal-
ization, and complete amplifier protection.
Mackie Designs has implemented a
unique “Vacuum Tube” philosophy for
amplifiers designed for mid- and high-
frequency reproduction. The FUSSION
3000 features two high-precision MOSFET
amplifiers, one for the mid-range driver and
a modified version for the high-frequency
compression driver. Both amplifiers are de-
signed to emulate the celebrated warmth
and transparency of vacuum tube amps.
The result is the clearest and most accurate
reproduction available.
Each 12˝ woofer handles 350 watts RMS
long term. Arraying four woofers within
the cabinet allows the FUSSION 3000 to
produce very deep, precise low frequencies.
The array is also much “quicker” than a
single 18˝ or double 15˝ woofer array be-
cause each diaphragm is significantly
lighter and faster.
The low-frequency amplifier module is
an excellent example of the efficiency of ac-
tive designs. The amplifier produces 1500
watts RMS of power from a module taking
up the area of only a single sheet of paper.
The key to producing transients quickly is
the availability of tons of power. That’s why
the FUSSION 3000 uses an exorbitant
quantity of high-voltage capacitors in the
power supply to store the necessary energy.
To ensure long-term reliability and perfor-
mance, the amplifier modules are mounted
on a huge three-square-foot heatsink, elimi-
nating the need for fans, dramatically
extending life expectancy, and eliminating
maintenance cycles.
The FUSSION 3000 is the first profes-
sional speaker system to completely create an
ideal union between speakers and amplifiers.
The input and control panel offers un-
precedented signal routing flexibility. All
connections are made via XLR connectors.
There is a Main Input with a Loop Out for
connecting to other enclosures. Addition-
ally, there is a Sub-Out connector for
connecting to the FUSSION 1800AS active
subwoofer system. This output incorporates
low-pass and subsonic filtering as well as
complete amplifier protection for delivering
a line-level signal below 85Hz. For sound
reinforcement situations where “fill” speak-
ers are needed, there is a Fill Out connector
with level and (0º/180º) phase control
(this signal is high-pass only above 85Hz).
The FUSSION 3000 can run on 115VAC or
230VAC and features soft-start circuitry that
eliminates “pops” and precisely controls in-
rush surges.
The cabinet is constructed of 13-ply,
18mm thick baltic birch wood with built-in
fly points for suspending with approved
rigging hardware.
