Series amplifi ers deliver
superior sonic accuracy and enor-
mous amounts of power from a low-
profi le design, and are perfect for touring and
fi xed installations.
The Crown
®
Macro-Tech 02 Series amps are
enhanced versions of the Macro-Tech line.
They offer the same features and performance
of the original Macro-Techs while delivering
key added benefi ts that continue to expand the
versatility of this distinct product line.
When it comes to manufacturing amplifi ers,
there are no shortcuts to quality. Crown’s
Macro-Techs have proven themselves time and
time again in some of the most demanding
applications in the world.

Specifi cations
Note: Specifi cations relate to120 volt, 60 Hz units in Stereo
mode with 8-ohm loads and an input sensitivity of 26 dB gain
at 1 kHz rated power unless otherwise specifi ed. Specifi ca-
tions for units supplied outside the U.S.A. may vary slightly at
different AC voltages and frequencies.
Power
Output Power: See power charts below.
Load Impedance: Safe with all types of loads.
Rated for 2 to 16 ohms in Stereo, 4 to 16
ohms in Bridge-Mono and 1 to 4 ohms in
Parallel-Mono mode.
Voltage Gain at 1 kHz, 8 ohm rated output:
MA-602: 54:1 ±6% or 35 dB ±0.5 dB at
0.775 volt sensitivity.
30:1 ±6% or 30 dB ±0.5 dB at 1.4 volt
sensitivity.
20:1 ±6% or 26 dB ±0.5 dB at 26 dB gain at
the maximum level setting.
MA-1202: 64:1 ±6% or 36 dB ±0.5 dB at
0.775 volt sensitivity.

46:1 ±6% or 33 dB ±0.5 dB at 1.4 volt
sensitivity.
20:1 ±6% or 26 dB ±0.5 dB at 26 dB gain at
the maximum level setting.
Required AC Mains: 50/60 Hz; 100, 120, 220
and 240VAC (±10%) units are available. All
draw 100 watts or less at idle. Current, voltage
and frequency requirements are provided on
the unit’s back panel.
AC Line Connector:
MA-602 and MA-1202: NEMA5-15P (15A)
MA-2402: NEMA 5-20P (20A)
Performance
Frequency Response: ±0.1 dB from 20 Hz to
20 kHz at 1 watt.
Phase Response: ±10 degrees from 10 Hz to
20 kHz at 1 watt.
Signal-to-Noise Ratio:
A-weighted: Better than 105 dB below rated
full bandwidth power.
20 Hz to 20 kHz: Better than 100 dB below
rated full bandwidth power.
Total Harmonic Distortion (THD) at full-band-
width power: Less than 0.05% from 20 Hz to 1
kHz increasing linearly to 0.1% at 20 kHz.
Intermodulation Distortion (IMD): (60 Hz and
7 kHz at 4:1) Less than 0.05% from 163 mil-
liwatts to full bandwidth power.
Damping Factor: Greater than 1,000 from 10
Hz to 400 Hz.
Slew Rate: (Slew rates are limited to useful lev-
els for ultrasonic/RF protection.) Greater than
13 volts per microsecond.
Features
• Crown’s Grounded Bridge™ design delivers
large voltage swings without using easily
stressed output-transistor confi gurations like
conventional amplifi ers. The results are lower
distortion and superior reliability.
• Patented ODEP
®
(Output Device Emulation
Protection) circuitry compensates for over-
heating and overload to keep the amplifier
working when others would fail.
• IOC
®
(Input/Output Comparator) circuitry im-
mediately alerts of any distortion exceeding
0.05%, providing dynamic proof of distortion-
free performance.
• Enhanced PIP2™ (Programmable Input Pro-
cessor) connector accepts new accessory
modules that tailor the amplifi er to suit specifi c
applications, such as networking via HiQnet™
or TCP/IQ™.
• Balanced XLR and
1
/
4
-inch (6.35-mm) phone
jack inputs for each channel on the standard
PIP2-FXQ module.
• Full protection from shorted, open and mis-
matched loads; general overheating; DC;
high-frequency overloads; and full protection
from internal fault are provided by our latest
protection scheme: “Quad-Mute.”
• Three Year No-Fault Full Warranty completely
protects your investment and guarantees its
specifi cations.
