U240:1 Power amplifier
Power amplifier 240W, 1 channel
- Full power output supporting 4Ω, 8Ω, 70 V and 100 V
- EMG override input, ensuring critical messages are heard clearly
- Contact override with 2-tone chime for attention-grabbing alerts
- 120 Hz high-pass filters to customize audio output and eliminate unwanted low-frequency noise
- Space-saving compact ½ rack design, providing versatility without compromising performance
- Remote activation of standby mode with Remote OFF (Stand by), enhancing energy efficiency
Introducing the U240:1, a 240 W power amplifier designed to cater to the demands of small to mediumsized installations, where paramount considerations include quality, performance, and unwavering reliability. This amplifier is ideal for background music and crystal-clear voice announcement applications, making it a perfect fit for diverse environments such as bars, restaurants, retail outlets, educational institutions, houses of worship, museums, galleries, transport hubs, and conference centers. Thanks to its compact size, standing just one rack unit high and half rack wide, the U240:1 presents numerous installation possibilities, even in spaceconstrained settings. Included brackets facilitate both single and dual rack-mount configurations, while desktop and under-counter installations are equally viable. When rack-mounted side by side, two amplifiers can seamlessly inhabit a single rack unit, optimizing space utilization and effectively doubling both channel count and output power.
