MICRO-TECH SERIES

he Crown

Micro-Tech

600, 1200 and

2400 are the original industry standards

for touring amplifiers. Micro-Tech ampli-

fiers 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 amplifiers would fail.

Micro-Tech

amplifiers use proven technology

and a miniaturized design to deliver terrific

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

amplifiers 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 amplifier.

Plus, your investment in a Micro-Tech ampli-

fier 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.

Specifications

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 specified. Specifications

for units supplied outside the USA 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 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

available.

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

milliwatts 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

configurations like conventional amplifi-

ers. The results are lower distortion and

superior reliability.

• Patented ODEP

(Output Device Emula-

tion Protection) circuitry compensates for

overheating and overload to keep the

amplifier 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,

general 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.

• The best Three-Year, No-Fault, Fully

Transferable Warranty in the business.
