The I/O Tab in the ZATO CONNECT's main menu includes three sub-menus, which can be accessed via the shelf menu on the left side of the menu window.

Input:
The Input menu includes the Video Input section on the left, allowing you to toggle between HDMI and USB UVC video input sources.

To the right, under SIGNAL, the ZATO outlines the specifications of the input signal.
The signal specification consists of a short version of the resolution, the scan type, and the frame rate.

Example: 1080p30
Resolution: 1080 (1920 x 1080)
Scan Type: p (Progressive)
Frame Rate: 30 (30 fps)

Compatible resolutions: 1080 (1920 x 1080) & 720 (1280 x 720)
Compatible Scan Types: p (Progressive)
Compatible Frame Rates: 23.98, 24, 25, 29.97, 30, 50, 59.94, 60

Output:
The Output menu details the output signal specifications of the ZATO CONNECT.

There is a row each for both HDMI and USB UVC outputs. Both have a dedicated SIGNAL section that details the signal coming out of either port.

Note: "Video Output USB" is assigned to the USB-C port labeled USB 2 on the rear of the device. Compared to USB 1, which just acts as a webcam input, it's a multipurpose port that may also be used as a connection point for the included USB-C to Ethernet adapter.

Note: While the HDMI Out port supports outputting 1080p signals at up to 60fps, the USB UVC output is limited to a maximum output frame rate of 30fps. If the ZATO CONNECT's input signal surpasses 30fps, the ZATO's USB UVC output will automatically drop frames to output a signal at half of the original frame rate.
Example: HDMI Input = 1080p60, HDMI Output = 1080p60, USB UVC Output = 1080p30

Audio:
The ZATO CONNECT comes equipped with a built-in Audio Mixer.

The mixer consists of 3 stereo audio meters. There is one for each audio input (Mic/Line, HDMI, USB), as well as the fourth pair of stereo meters for the output mix.
To add an audio source to the mix, press the button below the corresponding meter. Pressing the button again removes the source from the mix.
After adding a source, you can adjust the volume/gain via the slider to the right of each meter to make sure that it's mixing well with the audio coming from the other channels.
Once the independent channel volumes have been adjusted to your liking, you may make final adjustments via the Output Mix slider.

Note: Both Line (-10 dBu) and Mic Levels (-40 dBu) are supported. You may switch between them by pressing the label text on the right side of the menu window.
