AES3 Output Sample Rate Configuration
The AES3 output sample rate can be configured using the HTML5 Toolbox Web-GUI. See
Configuring AES3 Audio
1. Open the HTML5 Toolbox Web-GUI and click Audio in the Menu Bar, then click Audio
Options to display the Audio Options panel.
2. Click the AES Output Clock drop-down menu to select your preferred AES Output Clock
setting, then click Save.
Audio Reference Levels
By default, the PPM METERS on the front of the codec, or in the HTML5 Toolbox Web-GUI, use
dBFS to express nominal operating, headroom and noise floor levels. The codec can also
automatically adapt to different Tieline reference scales. A Tieline codec with proprietary Tieline
session data enabled will automatically adjust the reference level to suit G5 and G3 codecs, or
Report-IT. When connecting to a non-Tieline codec, or a Tieline codec without session data enabled,
the codec will use the Tieline G6 reference scale setting.
The default Tieline G6 audio reference scale displayed on the PPMs when connecting to a Tieline
G6 codec is -40dBFS to 0dBFS. Using this reference scale audio peaks can safely reach 0dBFS
without clipping, providing 20dB of headroom from the nominal 0vu point.
Important Note: If a codec supports multiple stream programs and the Auto (default)
reference level is selected, the first codec to connect will configure the reference level
used for all subsequent connections. I.e. If a G5 codec connects first then the G5 Audio
Reference Level will be configured for all connections.
To adjust this setting:
1. Open the HTML5 Toolbox Web-GUI and click Audio in the Menu Bar, then click Audio
Options to display the Audio Options panel.
2. Click the Reference Level drop-down menu and select the correct option, then click Save.
