 600, 1200 and 
   2400 are the original industry standards 
   for touring amplifi ers. Micro-Tech am-
plifi ers are known around the world as the 
benchmark for high-density, ultra-pure power 
in a compact package. In addition, each model 
gives you Crown’s legendary ODEP
®
 protection 
to keep the show going long after other ampli-
fi ers would fail.
Micro-Tech amplifi ers use proven technol-
ogy and a miniaturized design to deliver 
terrifi c value for their size, weight and price. 
Crown’s patented ODEP protection circuitry 
and Grounded Bridge
 output stages combine 
to provide performance and reliability that 
surpass traditional designs. Micro-Tech ampli-
fi ers also have an independent high-voltage 
power supply for each channel. This approach 
results in extremely low crosstalk and makes 
it possible to use each channel as a separate 
amplifi er.
Plus, your investment in a Micro-Tech ampli-
fi er is backed by Crown’s unequaled Three-
Year, No-Fault, Fully Transferable Warranty that 
covers everything.

Series, contact the Crown Technical Support 
Group at 800-342-6939 or 574-294-8200.

Specifi cations
The following applies to 120 VAC, 60 Hz units in Stereo mode 
with both channels driven into 8 ohm loads and an input 
sensitivity of 26 dB unless otherwise specifi ed. Specifi cations 
for units supplied outside the USA may vary slightly at differ-
ent 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 mode, 4 to 
16 ohms in Bridge-Mono mode, and 1 to 4 
ohms in Parallel-Mono mode.
Voltage Gain (at maximum level setting): 
MT-600: 20:1 ±6% or 26 dB ±0.5 dB at 26 
dB gain setting. 55:1 ±6% or 35 dB ±0.5 dB 
at 0.775 volt sensitivity; 31:1 ±6% or 30 dB 
±0.5 dB at 1.4 volt sensitivity.
MT-1200: 20:1 ±6% or 26 dB ±0.5 dB at 26 
dB gain setting. 64:1 ±6% or 36 dB ±0.5 dB 
at 0.775 volt sensitivity; 34:1 ±6% or 31 dB 
±0.5 dB at 1.4 volt sensitivity.
MT-2400: 20:1 ±6% or 26 dB ±0.5 dB at 26 
dB gain setting. 83:1 ±6% or 38 dB ±0.5 dB 
at 0.775 volt sensitivity; 46:1 ±6% or 33 dB 
±0.5 dB at 1.4 volt sensitivity.
Required AC Mains: 100, 120, 220 and 
240VAC (±10%), 50 and 60 Hz units are avail-
able.  
AC Line Current:
 AC mains current, frequency and voltage 
requirements are provided on the unit’s back 
panel.
 At  Idle:  All amps draw no more than 
 90  watts.
AC Line Connector: All units are shipped with 
an appropriate plug and cord for the required 
AC voltage.
Performance
Frequency Response: ±0.1 dB from 20 Hz to 
20 kHz at 1 watt.  
Phase Response: ±10 degrees from 20 Hz to 
20 kHz at 1 watt.
Signal to Noise Ratio: 
 A-Weighted: 
 Better than 105 dB below full bandwidth 
power.
  20 Hz to 20 kHz: 
 Better than 100 dB below full bandwidth 
power.
Total Harmonic Distortion (THD): Less than 
0.5% at full bandwidth power 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: Better than 1,000 from 10 Hz 
to 400 Hz.
Common Mode Rejection (CMR): At rated full 
bandwidth power, better than 70 dB from 20 
Hz to 1 kHz falling linearly to better than 50 dB 
at 20 kHz.
DC Output Offset (shorted input): < ±10 mV.
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 amplifi er 
working when others would fail
• 
High damping factor provides superior 
motion control over low-frequency drivers 
for clean, accurate low end
• 
Full protection against shorted outputs, 
open circuits, DC, mismatched loads, gen-
eral overheating, high-frequency overloads 
and internal faults
• 
1/4-inch and balanced XLR input connec-
tors
• 
Ground lift switch to isolate chassis and 
phone jack audio grounds
• 
Internal three-position input sensitivity 
switch provides settings of 0.775 and 1.4 
volts for standard 1 kHz power, and 26 dB 
voltage gain
• 
Three-Year, No-Fault, Fully Transferable 
Warranty completely protects your invest-
ment and guarantees its specifi cations
