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

Architects’ and Engineers’ Specifications
1. GENERAL.
The amplifier shall have a free-standing
frame with front and rear brackets for rack-mounting, and
supplied with four resilient feet suitable for table-top place-
ment. The amplifier shall be capable of two-channel opera-
tion, with a switch to place the amplifier into single-channel
operation by bridging the outputs of the two channels.
2. POWER OUTPUT.
The two-channel power amplifier
shall deliver a rated continuous average sine wave power
output over a 20Hz to 20kHz bandwidth of 425 watts RMS
into 8 ohms per channel, 700 watts into 4 ohms, and 1000
watts into 2 ohms with both channels operating, with no
more than 0.05% total harmonic distortion. In single-channel
operation it shall deliver 1400 watts RMS into 8 ohms and
2000 watts into 4 ohms, with no more than 0.10% total har-
monic distortion.
The power amplifier shall deliver a maximum continuous
average sine wave power output at mid-band of 500 watts
RMS into 8 ohms per channel, 850 watts into 4 ohms, and
1300 watts into 2 ohms with both channels operating, with
no more than 1% total harmonic distortion. In single-channel
operation it shall deliver 1700 watts RMS into 8 ohms and
2600 watts into 4 ohms, with no more than 1% total harmonic
distortion.
3. POWER SUPPLIES.
All necessary operating voltages for
the amplifier shall be provided by an internal power supply. A
master power switch shall be located on the front panel along
with a green power-indicating light.
4. INPUT CHANNEL CONNECTIONS.
Each monaural input
channel shall have an electronically balanced line-level input,
presenting no less than a 20k ohm impedance to the source.
Each input shall have an input sensitivity of +4 dBu, requiring
no more than 1.23V RMS to be driven to rated output into
a 4-ohm load. The input connector shall appear on the rear
panel as a female XLR-3 type connector. In addition, each
monaural input channel shall have a parallel 1/4" TRS phone
jack and a male XLR-3 type connector, which can be used
as inputs or “thru” jacks for daisy-chaining the input signal
to another amplifier, or a high- or low-frequency crossover
output for subwoofer applications. Pin 2 of the XLR connec-
tors, and the tip of the 1/4" TRS phone jack, shall be non-
inverting.
5. INPUT CHANNEL LEVEL CONTROLS.
Each monaural
input channel shall be equipped with a gain control appearing
on the front panel, each having 20 detent positions, and cali-
brated in dB and volts.
6. FRONT PANEL INDICATORS.
Each channel shall have
an associated six-segment LED meter appearing on the front
panel, capable of displaying signal present, –20 dB, –9 dB,
