Help with Linear Acoustic I/O

[arg2013]

Good morning,

I have recently been given a used AERO.air II (newer model) by Linear Acoustic.

I am having an unbelievably difficult time getting the box to recognize the audio coming in through its inputs.

The audio is coming from PC and thus far I have tried the following audio interfaces:

- Orban Optimod PC-1101 breakout cable w/Canare 110-75 Ohm transformers (as Linear Acoustic suggests)
- ESI U24 XL using it's digital IN and OUT ports on RCA connectors with RCA to BNC cables

Needless to say, both attempts were unsuccessful. I've gone through the I/O Settings menu on the AERO.air and selected AES 1/2 as the input and output options for BNC ports 1 and 2.

The only way that audio is passed through the box is if I enable "Master Bypass". When all bypassing is disabled, no audio comes into the box nor leaves the box. This is apparent by:

1) The AERO.air's screen shows no audio activity on screen.
2) The Orban PC-1101 card's software mixer shows no audio is coming in through Digital Inputs.

I am very new to Linear Acoustic equipment. I have used the Orban PC-1101 with many other boxes with no issue. Typically though< I work in the analog world instead of digital and this is problematic only because Linear Acoustic machines do not have analog inputs (except for the dumbed down AERO.lite -- a great box but with limited parameter adjustment control).

Is there a particular USB or PCIe audio interface that you all can recommend that have worked successfully with Linear Acoustic hardware equipment? At this point, I am uncertain if the choice of audio interface devices am I using are the problem or if the particular AERO.air unit I have is ruined.

Any help would be very, very greatly appreciated.

Thanks!

I have recently been given a used AERO.air II (newer model) by Linear Acoustic.

First of all, here is a manual. I suggest reading it: https://www.telosalliance.com/image...Products/AERO_air_DTV_5.1_V1.18.01 Manual.pdf

The AERO is a TV audio processor designed for multi-channel surround up-and-down mixing to accommodate programming that has stereo, then Dolby Surround, then back to stereo as needed. The processor is probably set to recognize audio that is encoded with metadata. No metadata, no processing. The metadata is typically contained within the VANC channel of the video stream.
