MT-2400

he Crown® Micro-Tech®600, 1200 and T2400 are the original industry standards

for touring amplifiers. Micro-Tech am- plifiers 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- fiers would fail.

Micro-Tech amplifiers use proven technol- ogy 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 ampli- fiers 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-

M I C R O - T E C H S E R I E S

Features	• Full protection against shorted outputs,
• Crown’s Grounded Bridge™ design delivers	open circuits, DC, mismatched loads, gen-
	eral overheating, high-frequency overloads
large voltage swings without using easily
	and internal faults
stressed output-transistor configurations
	• 1/4-inch and balanced XLR input connec-
like conventional amplifiers; the results are
lower distortion and superior reliability	tors
• Patented ODEP® (Output Device Emulation	• Ground lift switch to isolate chassis and
Protection) circuitry compensates for over-	phone jack audio grounds
heating and overload to keep the amplifier	• Internal three-position input sensitivity
working when others would fail
	switch provides settings of 0.775 and 1.4
• High damping factor provides superior	volts for standard 1 kHz power, and 26 dB
motion control over low-frequency drivers	voltage gain
for clean, accurate low end	• Three-Year, No-Fault, Fully Transferable
	Warranty completely protects your invest-
	ment and guarantees its specifications

Year, No-Fault, Fully Transferable Warranty that covers everything.
