The Cloud Z8MK4 is a professional-grade, rack-mount (3U) mono audio mixer designed to manage audio across eight independent zones. It blends simple background music control and powerful microphone paging to provide a flexible solution for commercial environments like bars, hotels, offices, retail, and multi-area venues.
With six stereo input sources (balanced and unbalanced) and three mic inputs (including a dedicated paging mic), the Z8MK4 gives you full control of audio routing to each zone. Its digital paging interface (PM series compatible) enables cascading of mixers for more zones, while its switch-mode power supply supports up to 600 mA of internal accessories like EQ cards or remote input modules. Remote control of music level and source selection is available via optional wall remotes per zone.
The Z8MK4’s Facility Port lets you integrate optional LM‑2 or similar plates in each zone for local mic or line sources like laptops, DJ setups, or tablets. Priority settings — including mic-over-music and Line 6 priority — let you configure the system for announcements, emergency messages, and source overrides. Plus, EQ modules for different speaker brands, fire-alarm mute interface, and strong build quality make this a reliable center for multi-zone audio.
