4 – ARCHITECTS & ENGINEERS SPECIFICATION
The Dante interface unit shall provide one mic/line analog input on the front panel with a female XLR connector.
Selectable gains of 0dB, +25dB, and +40dB, and +48V phantom power option shall be provided via software for the XLR
input. The unit shall provide one line level balanced output with a male XLR connector. The unit will provide two RCA
line level inputs and one 3.5mm TRS line level input, both internally summed to mono. The unit will provide a 3.5mm
TRS line level output. The internal analog to digital signal conversion shall be performed at 24-bit resolution with a
sampling frequency of 48kHz. The Dante interface unit shall receive power over the Ethernet cable from an 802.3af PoE
compliant network switch. The Dante interface shall be wall mounted in a standard US dual gang junction box.
The Dante interface shall be compatible with Attero Tech Unify software for flexible control and monitoring in system
applications. The Dante interface shall be compliant with the RoHS directive. The Dante interface unit shall be
compliant with the EMI/EMC requirements for FCC and CE.
The Dante interface shall be the Attero Tech unD3IO.
