Professional audio metadata can be applied to the AERO.2000 to minimize processing and control functions, such as upmixing. AERO.2000 protects itself against loss of incoming metadata with reversion modes that apply user set reference loudness values.

    Getting Started Getting Started This user guide is intended to be read while in front of a running AERO.2000 unit. It is most helpful if the source(s) that will be used is actually connected to the AERO.2000. Doing this provides feedback to the user, via the meters and IP audio monitoring, about the configuration changes being made.

    • Connect AERO.2000 AES outputs AES Outputs 1/2 and 3/4 to the external watermark encoder inputs 1 and 2. • Connect external watermark encoder outputs 1 and 2 to AERO.2000 AES inputs 1/2 and 3/4. The viewer ratings encoder does not encode to the Ls or Rs channels so pairs 5/6 do not need to be routed outside the AERO.2000.
  • Page 91 1/2. When 5.1 surround is present it is on 3 entirely different pairs. For example, Pairs 3, 4 and 5. AERO.2000 can upmix pair 1 and automatically switch to the 5.1 surround pairs when 5.1 surround audio is present. If a program with stereo only content appears the AERO will switch back to the stereo source.
  • Page 92 Any 3 input pairs can be selected as the 5.1 surround source channels for Program 1 Input channels 1/2, 3/4, 5/6. These three AMX5.1 inputs are always used for the 5.1 surround program source. ©2016 LINEAR ACOUSTIC INC. THE TELOS ALLIANCE. ALL RIGHTS RESERVED Page 78...

    Troubleshooting Troubleshooting Troubleshooting AERO.2000 is reliable and easy to install. Most problems turn out to be wiring or configuration errors. However, it is a powerful processor with many possible configurations and user- adjustable parameters. • If you cannot find the source of a problem, simplify the signal path.

  • Page 94: The Unit Does Not Power On

    When using the AES-3 inputs the AES reference may be missing or at the wrong sample rate; the unit expects to lock to 48 kHz. AERO.2000 defaults to an internal 48 kHz reference if the external reference is removed or missing. This allows audio to continue, but with asynchronous inputs and outputs (due to the sample rate converters on each input pair).

    AERO.2000 User Guide July 2016 L16/1/18039 An Ethernet connection to the AERO.2000 that is unstable (i.e. bad port or other network issue) can cause the same issue as switching unsynchronized sources into the AERO.2000. The Ethernet connection must be stable.
