DG Systems has launched enhancements to its distribution service for spots and music. Its new Media Manager is a dedicated, on-site server. The company says this approach provides stations and agencies guaranteed delivery of spots and music. Promised benefits include no user intervention or dedicated phone lines; Web-based desktop access to audio, traffic and delivery status; and cost savings. For example, cuts can be accessed from multiple workstations on a LAN, instead of using ISDN lines at multiple facilities. Info: www.dgsystems.com.
