4 – ARCHITECTS & ENGINEERS SPECIFICATION
The AES67 break out Interface shall have two balanced mic/line analog inputs and two balanced line analog outputs. Each
analog input shall be capable of driving an AES67 audio stream and each analog output shall be capable of being driven
from an AES67 audio stream.
Each input channel shall have +48V phantom power, selectable via software on a per channel basis. Each input channel
shall have five gain levels: -12dB (pad active), 0dB, +15dB, +30dB and +45dB, selectable via software on a per channel
basis.
Each output channel shall have adjustable gain between 0dB and –60dB in 1dB increments plus a mute, selectable via
software on a per channel basis.
All parameter changes will be non-volatile and self-restoring in the event of AC or PoE power interruption.
The unit shall accept 24VDC or IEEE 802.3af standard PoE as power input. The unit shall be compliant with FCC
47CFR Parts 15B and 18 (Class A), EN 55011, ICES-003, CE (EN55022 Class A and EN55024 Class A), and RoHS
requirements.
The unit shall be the Attero Tech u I/O Interface
