OPERATION
Control and operation of the BrightEye 71/71-F is performed from the front panel or with the BrightEye
Control application. When controlling the module from the front panel, most, but not all of the control
settings and parameter choices will be available. For more comprehensive control, use the BrightEye
PC or Mac Control application.
Front Panel Controls and Indicators
The front panel shown in the figure below provides status indicators and control over module setup.
Status Indicators
The following status indicators are provided on the front panel:
• In – Illuminates green when a valid input is present on the SDI In connector.
• Mode – The currently selected mode (Mux or Demux) illuminates green.
• Group – The audio group (1, 2, 3, or 4) currently targeted for embedding or disembedding
(depending on module configuration) illuminates green when the selected group contains
audio, and illuminates red when the selected group does not contain audio.
• Gain – These controls allow for quick adjustment of Gain level for the four channel pairs.
Gain adjustment is done in conjunction with the VU indicators. For independent channel
adjustment, and other controls, use the BrightEye Control application.
• VU – VU output level and the status of the Gain adjustment for each channel pair is indicated
by the state of the VU and Gain indicators for each of the channel pairs. The VU indicator
illuminates red when the audio level exceeds the headroom level set by the user (with the
Peak Indicator control in the BrightEye Control application).
Additionally, the VU indicator illuminates orange when the output is above 0 VU, illuminates
green when the output is above -20 VU, and doesn’t illuminate when the output is below
-20 VU. The Gain indicator illuminates red when the gain level has been adjusted to a value
other than unity by the user. The 0 VU point corresponds in the digital domain to the digital
reference level (-18 or -20 dBFS).
• Mon Vol (Monitor Volume) – Illuminates green when monitor volume is set to unity, or red
when set to other than unity.
• Pwr (Power) – Illuminates green when the BrightEye unit has power and the internal voltage
regulator is functioning correctly.
