Cloud Electronics 46-120MK2 4-Zone Mixer Amplifier 4x120W (4Ω/8Ω/100V)
DETAILS
Cloud Electronics 46-120MK2 – Versatile 4-Zone Mixer Amplifier with Power Sharing.
The Cloud 46-120MK2 is a high-performance 4-zone mixer amplifier, designed for commercial audio distribution in environments such as hospitality, retail, education, and leisure. It provides independent source selection and volume control across four zones, delivering 120W per zone with support for low-impedance (4Ω/8Ω) and high-impedance (70V/100V) operation. A key feature of the 46-120MK2 is its power-sharing capability in 70V/100V mode, allowing for flexible speaker configurations and efficient power distribution.
Multi-Zone Control with Flexible Source Selection
Each of the four zones can be assigned its own audio source and volume settings, ensuring tailored sound distribution for different areas of a venue. Users can control source selection and volume levels directly from the front panel or remotely via optional RSL-6 / RSL-6A remote controllers, which can be installed in each zone for ease of use. This makes the 46-120MK2 ideal for businesses requiring independent music or announcements in multiple areas.
Comprehensive Connectivity & Digital Paging Integration
The 46-120MK2 features six stereo line inputs (four balanced) and two microphone inputs, with priority options that enable paging or emergency announcements to override music playback. It also includes a digital paging interface, making it fully compatible with Cloud PM-Series paging microphones for seamless integration into multi-zone PA systems.
Additional connectivity includes two auxiliary outputs, which can be assigned to different zones, and Ethernet & RS-232 ports for external control and system integration. The amplifier also supports remote music mute functionality, which allows it to be linked to a fire alarm system for automatic audio muting during emergencies.
Efficient Power Management & Reliability
The 46-120MK2 is designed for energy efficiency and reliability, incorporating an automatic standby mode to reduce power consumption when not in use. A universal power supply ensures stable operation in various installations, while built-in limiters, thermal protection, and short-circuit protection enhance safety and longevity.
