Device Drawings
- Display: Shows either an overview of system parameters or level meters for analog inputs, analog outputs, USB I/O, and expansion card I/O. The overview contains IP address, DHCP status, and communication LEDs for Ethernet, Dante, and ARC. Meters are scaled from -72 dBFS to 0 dBFS. Each segment represents 12 dB. If signal reaches clipping, the meter will get wider.
- Wake/Navigation Button: A single momentary push button cycles through the dashboard and system pages or dismisses fault notifications. A short press scrolls through menus or dismisses a fault notification. A long press toggles between the dashboard and system pages.
- Power: Accepts power from detachable IEC power cable (100-240 VAC, 50-60 Hz, 60 Watts max). Connect only to a grounded power outlet.
- ARC: Distributes power and RS-485 data to one or more ARC devices.
- A & B Ethernet Ports: 1000 Base-T Ethernet ports for Composer host control, and third-party accessory controllers over IP. Features auto-crossover sensing for direct device-to-device connections.
- C & D Dante Ports: 1000 Base-T Ethernet ports provide 128 (64×64) channels of Dante network audio. Requires optional Dante card.
- USB Host: USB 2.0 host port connects to external flash drive providing up 8 channels of .wav file playback and recording.
