DC1048
Integrated Audio Management
Installation audio processing becomes a whole lot easier with the introduction of the DC1048. Working in conjunction with both iCore and AudioCore, it’s easy to program the unit the way you want, and then unplug the computer, safe in the knowledge that settings can’t be changed, and even if they are, setting up timed presets ensures they’ll be back as they should be by the next morning! Units may be networked via RS485 and are compatible with the wireless Walkabout system.
