The U120:1 is a 120W single-channel power amplifier engineered for high-quality audio performance in small to medium commercial installations. It delivers dependable amplification for background music and clear voice announcements, making it ideal for retail spaces, restaurants, educational facilities, houses of worship, museums, galleries, transport hubs, and conference environments.
The amplifier supports full power output across 4½, 8½, 70V, and 100V systems, providing maximum installation flexibility. It features an EMG override input to ensure critical messages are always heard, along with a contact override function with a 2-tone chime for clear and attention-grabbing alerts. A selectable 120 Hz high-pass filter helps eliminate unwanted low-frequency noise for improved speech clarity and system performance.
Designed with installation versatility in mind, the U120:1 features a compact half-rack form factor and includes mounting accessories for rack, desktop, and surface installations. Two units can be installed side by side in a single rack space to increase system capacity while maintaining a minimal footprint.
