Micro-Tech® Series

 

The Original Touring Workhorse

 

 OVERVIEW

Crown's first touring workhorse, the Micro-Tech Series, delivers industry standard performance and reliability.

Able to drive low-impedance loads with ease, Micro-Tech amplifiers feature three separate power supplies for exceptional reliability and impressive power ratings. Our patented ODEP circuitry keeps the amplifier working long after others would quit. Grounded bridge circuitry doubles the available voltage without placing output transistors in stressful configurations like other more conventional amplifiers. The unique forced-air cooling system makes certain heat is dissipated quickly and evenly. As a result, you get maximum performance without the threat of damage to the amplifier or other system components.
