MICROTECH DA-21400 High-Power Class D 2-Channel Amplifier in a Compact 1U Design

The MICROTECH DA-21400 is the flagship model in the DA Series, delivering extreme power output in an ultra-compact
1U rack-mount design. Powered by advanced Class D amplification technology and a high-efficiency
switching power supply, the amplifier provides an impressive output of
2 x 1,400 watts at 8 ohms and up to 2 x 2,550 watts at 4 ohms.

This amplifier is designed for demanding applications that require high headroom and reliable power delivery,
such as driving 18-inch subwoofers or powering large line array speaker systems.
With a damping factor greater than 1000, the DA-21400 ensures precise control over large speaker drivers,
resulting in tight, powerful, and well-defined low frequencies.

The cooling system is intelligently designed with temperature-controlled fans to maintain optimal operating conditions
even during heavy use. Comprehensive protection circuits including over-voltage, under-voltage, and speaker short-circuit protection
ensure safe and reliable operation. These features make the DA-21400 an ideal amplifier for
touring sound systems, concert productions, and high-end entertainment venues.
