The U240:1 is a 240W single-channel power amplifier engineered for demanding small to medium-sized commercial installations where reliability, clarity, and installation flexibility are essential. It is ideal for background music and clear voice announcements across environments such as retail stores, restaurants, bars, educational facilities, houses of worship, museums, galleries, transport hubs, and conference centers.
Designed with full system flexibility, the U240:1 supports 4½, 8½, 70V, and 100V speaker systems, making it suitable for both low-impedance and distributed audio applications. It includes an EMG override input to ensure critical messages are always prioritized, along with a contact override function featuring 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 intelligibility and audio clarity.
The amplifier features a space-saving half-rack design that enables highly versatile installation options. It can be mounted in single or dual rack configurations, installed side-by-side to double system capacity, or deployed in desktop and under-counter setups using the included mounting accessories. This flexibility allows efficient use of space without compromising performance or output power.
