Overview The ControlSpace EP22-D is a 2-in/2-out audio interface utilizing Dante , a digital media networking technology from Audinate . It’s ideal for adding 2x2 channels of Dante audio I/O in a compact, unobtrusive unit. The two inputs use 3-pin Euroblock connectors for balanced or unbalanced connectivity and support either mic or line level signals. Each input also features a 24V phantom power option. The two outputs also use 3-pin Euroblock connectors and each provides a balanced line level output. Each output also has an optional +10dB analog boost. Connection to the Dante network is provided by a single Ethernet RJ-45 connector on the back of the unit. Note: The ControlSpace EP22-D has a label on one of the mounting flanges that lists the last 6 digits of the MAC address. Important for initial device identification, these digits are part of the device's default network name when detected by Bose ControlSpace Designer software. The full MAC address is also given on the back of the unit. The EP22-D is PoE powered over the network cable from a suitable PoE source (IEEE 802.3af) or a 12V DC power supply may be ordered separately. ControlSpace Designer software is used to configure the audio routing of this device and configure and control its specific features. The EP22-D’s small form factor and integrated mounting bracket allows for inconspicuous placement near sources or destinations, thus reducing the amount of analog cabling required. On flat mounting surface, mark screw locations through holes in the mounting flange. Secured the unit to the mounting surface using appropriately rated no. 6 screws through each mounting flange.
