AV mixers, which play a core role in audio-visual production is the A-PRO-4 that supports information sharing in real time, such as live video streaming via the internet. Particularly, the A-PRO-4 has professional-grade SDI, consumer-grade HDMI and analog video inputs, and one of the inputs has a built-in scaler that allows users to connect devices without worrying about resolutions or frame rates. For an external sound source, the unit has one stereo input available for adding a commentary or background music.
In addition, the unit has a VIDEO fader feature convenient for transitions and a 100 mm-stroke AUDIO LEVEL fader is available for mixing the five audio inputs.
You can fine-tune the levels with ease.
10-bit/4:4:4 Processing for up to 2K/60P
The 10-bit/4:4:4 internal processing provides clear video output with no color bleeding even for output to a projector or LED display.
Streaming Output via USB 3.0
Output of resolutions of up to 720x480/59.94i with USB 2.0 connection and up to 2048x1080/59.94P with USB 3.0 connection is possible.
Video signals in system formats non-compatible with this unit are automatically converted by the scaler to a compatible output when connected to the fourth input terminal.
External Synchronization Support
This allows you to build a synchronous system using this unit as a core system component, or integrate this unit into an existing system as a high-definition sub-switcher.
Supporting a Wide Range of External Controls
Moreover, the audio IN/OUT terminals may be used as GPI IN/OUT terminals.
One audio terminal can accommodate two GPI channels, so you may utilize eight GPI channels in total.
