LEM Commercial - Micro iAMP120

The MICROIAMP120 is a 120 W compact 1U half-rack mixer / amplifier designed for commercial applications requiring efficiency, reliability, and ease of use.

It features three balanced MIC / line inputs, with CH1 equipped with Phantom power and a VOX function for automatic priority management. A line input and an unbalanced AUX input are also available, allowing the connection of additional sources. A line output is also available for connection to external amplifiers or recording systems.

The amplified output can operate on both low-impedance loads (8 ohms) and 100 V constant-voltage lines, making the MICROIAMP120 suitable for distributed systems.

Class-D technology ensures high efficiency and low heat dissipation, while integrated overload, short-circuit and overheating protections ensure stable operation even during continuous use. It can be powered by either AC or 24 V_DC, making it suitable for systems with backup power.
