Installations are becoming increasingly more complex. Where microphones and speakers once had to be switched or even rewired by hand, now there are flexible routing options using presets and automated processes. The DSP matrix processor ZONE X 1208 from LD Systems enables all that and more.

Ethernet interface for remote control via the universal control software Xilica Designer; Ethernet Dante card optionally available

With its DSP hybrid architecture, the ZONE X 1208 can adapt your sound system for different circumstances and possible uses. Choose one of the different DSP templates and use the event scheduler to set up calendar-managed workflows with automated preset options. Everything you need: Twelve balanced mic/line inputs with low-noise microphone preamplifiers and separate switchable 48V phantom power as well as eight balanced line outputs are available. There are also eight GPI and GPO logic ports which can be used e.g. for automated processes and the integration of third-party devices. The front panel with only 1 RU looks very tidy. The ZONE X 1208 is easy to set up and manage via Ethernet with the universal software Xilica Designer (Mac/Windows) providing an overview of all connections and settings. Thanks to the additional REMOTE bus connection, the ZONE X 1208 is already equipped for future remote panels and paging microphones from LD Systems. An Ethernet Dante card with 64 x 64 channels can be installed as an upgrade option for audio over IP applications. The Dante standard opens up a whole world of compatible devices from different manufacturers for all conceivable applications.

From routing and processing of different microphone and speaker groups, in a church for example, to complex multi-room installations with calendar-managed routing for different configurations - the ZONE X 1208 makes everything possible.
