Connection Ports
All of the connections for AERO.one are on the rear panel and are described in detail be-
low. See Chapter 5: Specifications for specific pinouts.
•
Metadata I/O: RS-485 connection accepts the metadata output of any Dolby equip-
ment (DP572, DP570, etc...) or any Dolby-compatible metadata source. Used to con-
trol upmixing and other functions.
•
SDI Input/SDI Output: Option allows for de-embedding and re-embedding any of
the 16 available channels in an applied HD or SD-SDI signal. VANC metadata extrac-
tion per SMPTE 2020 methods A and B is also supported.
•
GPI/O: Connect dry contact closures here to control upmixing and EAS on/off.
Note that GPI functions require held closures for the duration of the desired function.
Status of upmixing will be reflected on the corresponding GPO pin.
•
ETHERNET: Used for firmware upgrades.
•
Main Audio Input: Connect the 48kHz PCM signals to these inputs. The input chan-
nels are arranged as follows: 1/2 = Left front/Right front, 3/4 = Center/LFE, 5/6 =
Left surround/Right surround. 7/8 is unused in the latest version (was formerly EAS
input, now moved to Encoder Bypass input).
•
Enc. A Bypass/EAS Input: Bypass input for Dolby Digital (AC-3) encoder A. Ac-
cepts output of external encoder for fail-safe operation. Can also be used as EAS input.
•
AES REf Input: Apply 48kHz DARS (Digital Audio Reference Signal) here and
choose AES Ref as clock source in Setup->I/O menu. Note that this is useful with
some MPEG video encoders which provide an AES reference output.
NOTE: Appropriate reference must be applied and selected for proper operation.
