The 1100DCI Device Control Interface is an expansion unit used in a GLOBALCOM system to provide a remote control interface method to networked output devices. The 1100DCI hosts an interface server that provides direct access to control program selection, background music (BGM) selection, and output levels in real time using mobile devices. An iOS, Android, Windows Mobile, or any device with a compatible web browser that is allowed to connect to the system network can be used to control output devices such as the DNA and Titan series amplifiers, 1502AO audio output module, or T9116 zone output processor.
