Mackie Designs Inc. continually engages in research related to product improvement. New material,
production methods, and design refinements are introduced into existing products without notice as a
routine expression of that philosophy. For this reason, any current Mackie Designs product may differ
in some respect from its published description, but will always equal or exceed the original design
specifications unless otherwise stated. ©1999-2002 Mackie Designs Inc. All rights Reserved. Mackie and

–6 dB, –3 dB, and overload. Each channel shall have inter-
nal status LEDs appearing on the front panel to indicate
activation of protect mode and short-circuit protection.
Two temperature status LEDs shall appear on the front
panel, one to indicate normal operation (COLD) and one to
indicate thermal protection (HOT).
7. PROTECTION FEATURES.
The amplifier shall pro-
vide delayed activation of the outputs at turn-on. Each
channel shall have a short-circuit protection circuit for
detecting excessive current flow at the output that, when
activated, mutes the output for four seconds. The short-
circuit protection shall continuously cycle on and off until
the shorted condition is remedied. The amplifier shall
have a thermal protection circuit to protect the power
devices from over-temperature operation. The circuit shall
activate when the internal temperature crosses the safe-
operating threshold and, when activated, mute the out-
puts until the internal temperature cools to a safe-oper-
ating temperature, at which time amplifier shall resume
normal operation. The amplifier shall have a fan to cool
the heat-producing internal components, drawing cool air
in from the front, and exhausting warm air out through
both sides. The fan speed shall be variable, the speed
being determined by the internal temperature and the sig-
nal level present at the output. The amplifier shall have
an SCR crowbar circuit to protect the speakers against a
catastrophic amplifier failure. The circuit shall activate in
the presence of continuous DC at the speaker outputs,
and shall shut the amplifier down by turning off the high-
voltage rails.
8. OUTPUT CONNECTIONS.
Each channel shall have
a heavy-duty 5-way binding post speaker output connector
appearing on the rear panel, with 3/4" spacing for accom-
modating standard double banana plugs as well as spade
lugs or bare wires. Each channel shall have a Neutrik
brand Speakon
®
output jack appearing on the rear panel
in parallel with the binding post. A separate Speakon
®
connector shall be provided for the bridged mode mono
output.
9. AMP MODES.
The amplifier shall have a three-way
switch appearing on the rear panel for selecting the mode
of operation, which shall include stereo (two channels in,
two channels out), mono (one channel in, two channels
out), and bridge (one channel in, one channel out, bridged
between both speaker outputs).
10. OUTPUT APPLICATIONS.
The amplifier shall have
a three-way switch appearing on the rear panel for select-
ing between limiter on, limiter off, and subwoofer mode.
The defeatable electronic limiter circuit shall sense the
onset of clipping and shall limit the input signal and there-
by prevent the output from clipping.
11. CROSSOVER.
Each channel shall have a 4th order
Linkwitz-Riley, 24 dB/octave crossover with switch-select-
able crossover frequencies of 60, 90, or 120Hz. When the
subwoofer mode is selected, the two input channels shall
be summed and the low-frequency output from the cross-
over shall be routed to the selected channel. In the full-
range modes, the high-
or low-frequency output of the
crossover may be routed to the input thru connector via a
rear panel switch.
11. LOW-CUT FILTER.
Each channel shall have a low-
cut filter with a variable frequency control appearing on
the rear panel covering a range of 10Hz (OFF) to 170Hz.
12. PHYSICAL CONFIGURATION.
The amplifier shall
be rack-mountab
l
e with rear support rails for extra sup-
port, and shall have a steel chassis frame painted gray-
black. The amplifier shall be 19" wide (483 mm), 5.2" (3U)
tall (132mm), and 16.67" deep (423 mm), and shall weigh
55 pounds (25 kg).
13. DESIGNATION.
The power amplifier shall be a
