Page 7: Safety Information
Safety Considerations and Information should be disposed of in a responsible manner. The DCM-1 is powered by a separate Power Supply Unit (PSU), which must be earthed. Ensure that the mains power supply provides an effective earth connection using a three- wire termination. -
Page 8: Welcome
It is recognised that the tasks of design/set-up, physical installation and day-to-day operation of an audio system based on the DCM-1 are likely to be performed by at least three different people. You will find, therefore, that this manual is divided into sections: •... -

Page 25: Connections And Wiring
The remote plates all have two RJ45 sockets, labelled OUTPUT and LINK. The “first” plate in a daisy‑chain wiring system should be connected to the DCM-1 using its OUTPUT socket. The LINK socket on this plate should be connected to the OUTPUT of the next plate in the chain, and so on until the last plate in the chain. -

Page 30: Section 3 : Configuration
The DCM‑1 can be configured in a variety of ways to suit all installed situations. Most configuration functions are accessed through the menu system. For convenience, the DCM-1’s basic block diagram is repeated above. The menu system has two modes: User Mode and Installer Mode. -

To permit paging of Zones 9 and higher in a system utilising two DCM‑1s, a fixed numeric offset of 8 should be set in the “second” DCM-1 (and left at the default value of 0 in the “first”). With the first DCM‑1 feeding audio to Paging Zones 1 to 8 and the second to Paging Zones 9 to 16, correct paging of the higher-numbered Zones will result. -
