The LV 5700A Multi-SDI monitor is provided with audio monitoring, measurement and data analysis capabilities for embedded AES/EBU monitoring (audio is disembedded and output via 4 BNC connectors; 8 channels, as standard). Facilities using separate (non-embedded) AES/EBU audio will need to use the OP75 External AES/EBU Inputs option in order to monitor external AES/EBU. All of the embedded audio measurement, monitoring and analysis abilities of the LV 5700A are also available for monitoring external AES/ EBU using the OP75 Option 75 adds monitoring and display for 8-channels of AES/EBU digital audio inputs. Surround sound image, lissajous, bar graphs and digital levels are displayed. An on-screen display indicates if the embedded audio is synchronous with the external AES/EBU input audio and shows lock/unlock or no signal. A speaker is also included to allow monitoring of the selected channel.
