High-Power 120 Watt Mixer Amplifier: Delivers consistent 120 W output, providing reliable sound coverage for commercial and industrial spaces.

Four Mic/Line Inputs with Individual Volume Controls: Each input has dedicated front-panel gain controls for precise balancing of multiple audio sources.

Configurable Priority Muting: Automatically lowers background music when announcements occur, ensuring clear communication over ambient noise.

Low-Z and High-Z Operation: Supports 4/8 Ω low-impedance and 70/100 V high-impedance speaker systems. Includes a switchable 80 Hz high-pass filter for enhanced clarity.

Energy-Efficient Design: Auto Ramp circuitry reduces power consumption by enabling quiet, fast power up and down, saving energy without affecting performance.

Direct Drive, Constant Power Class D Technology: Ensures high-fidelity sound with superior audio performance and minimal distortion (<0.05 %).

GPI Remote Volume Control: Supports RJ‑45 Ethernet connection for wall-mounted or tabletop controllers, enabling convenient remote operation.

Fanless, Convection-Cooled Design: Eliminates fan noise while maintaining efficient heat dissipation for continuous, reliable operation.

Auxiliary Output for System Expansion: Easily integrates additional amplifiers or distributed audio systems through the dedicated aux output.

Flexible Rack, Table, and Wall Mounting: The 1U, half-rack enclosure with joining brackets allows versatile installation in any commercial environment.

Intuitive Front Panel Operation: Front-panel power, gain, and tone controls simplify operation for both technical and non-technical users.

Robust Safety and Protection: Includes thermal, overcurrent, DC, and high-frequency protection, as well as controlled start/stop and load safeguards.
