120W half-rack 100V/8Ω Class-D mixer amplifier - LEM COMMERCIAL GEN-MICROIAMP120

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 VDC, making it suitable for systems with backup power. User benefits Compatibility with 8 ohm loudspeakers and 100 V lines for maximum flexibility 3 balanced MIC / line inputs, with automatic priority over CH1 via VOX Microphone input with priority for announcements and service messages Line output for system expansion Dual AC and 24 VDC power supply for systems with emergency backup Compact size for installation in small spaces and lightweight racks Areas of use Shops Offices Waiting rooms Restaurants Public spaces Background music and announcement systems
