Cloud Electronics DCM1e Ethernet Digital Control Zone Mixer

The DCM1e is a new Ethernet version of the popular DCM1 Digital Control Zone Mixer. The addition of an ethernet port on the rear panel of the new DCM1e allows its own on-board web-server to be connected via an RJ-45 socket to an independent or existing switch or router. This feature means the new DCM1e can be configured and controlled remotely by any mobile device or PC connected to the same network.

Using the web browser of any mobile device Users have limited installer defined controls via simple and intuitive interface pages. Power Users are provided with additional installer defined controls, whilst Installers have administrator status via a password protected Configuration Options screen.

Multiple devices can connect and operate the DCM-1e concurrently, providing complete flexibility and control for up to eight separate zones, if required.

Key Features

• 8 stereo line inputs (1 balanced), with input level trims (via menu system)
• 8 balanced line outputs (2 stereo + 6 mono)
• Any source may be routed to any zone at any level
• 4 Extension Ports for optional remote line input modules (balanced or unbalanced), using Cat 5 UTP cable
• 4 Mic Inputs for optional remote mic input modules, using Cat 5 UTP cable
• External inputs (mic or line) may be routed to any zone
• RJ45 interface for Cloud PM Series digital paging microphones
• Separate analogue paging mic input with standard short-to-ground zone selection
