本教程由 Videoguys.com.

In Part 1 of this two-part series on the 罗兰V-60HD生产切换器 (下面的图1), we did an overview of the functionality and the features of this powerful video switcher. 在第二部分中, I’m going to take a look at the Smart Tally system, as well as the auto-mixing feature on the audio side.

The first feature I'm going to review is the Smart Tally feature. The Smart Tally feature allows you to communicate with your camera operators, 尤其是在嘈杂的环境中. Instead of just using intercom to let your camera operators know when they're live, 在很多嘈杂的环境中, a visual signal is actually more effective, and that's where the Smart Tally system comes into play.

You would set up your local area 网work and connect up a WiFi router with a video switcher, and then each camera operator would have their own mobile device that they'd log into the WiFi on th WiFi router. I've done this on this cellphone shown in 图2(下面).

If I go to Input 3, or Channel 3, it's gray (图3，左), because right now, 3 is not on the Preview or the Program bus. If I take 3 on the preview bus, it turns green instantly (图3, right). This lets the camera operator know that if they’re camera operator 3, they're on standby. 下一个是他们. Once they go live, I'm going to cut to 3, and it goes red. So, a very effective system of communicating with your camera operators, 尤其是在嘈杂的环境中, and it complements the use of intercoms for this camera communication.

音频Auto-Mixing

The second advanced feature that I'm going to look at is the audio Auto Mixing feature on the Roland V-60HD (下面的图4). This is a feature that allows you to connect multiple audio inputs onto the switcher. Based on the weighting—the priority levels that you have set—the video switcher will automatically balance those levels, decide which ones are to be louder, 哪一个更安静.

This feature is much easier to understand if you can see and hear it in action. I do a quick demonstration of this at the 2:00 mark in the video above

The Auto Mixing and the Smart Tally features on the Roland V-60HD are two very advanced features that basically allow you to do a lot more and handle larger productions without adding extra gear.
