4-SDI Multiviewer via HDMI

S-9204 is a solution of monitoring 4-ch SDI by a single HDMI monitor or television. There’re 3 display modes: Quad-split display, one channel full screen switching display, and PGM/PVW switcher mode display.
It’s 19-inch 1U designed, and can be installed in standard broadcast racks.



4-SDI Switcher via SDI

Now you can use S-9204 as a basic SDI switcher in the field producing. It support PGM channel output via SDI, direct switching by pressing the channel buttons on the front panel, and supports PVW to PGM switching under the PGM/PVW display mode.
The PGM switching output offers zero delay.



Input and Output

S-9204 Quad Viewer supports:
HD/SD-SDI input ×4
HD/SD-SDI loop output ×4
HDMI Quad-split output ×1
SDI switching output ×1
3.5mm analog audio output ×1

Note: The input SDI signals require the same format.



Embedded Audio Monitoring

By audio meters or headphone output

The HDMI multiview output supports 2 channels of SDI embedded audio meters display for each input channel. The audio meter is green, and will turn yellow when exceeds -20dB, and turn red when exceeds -9dB.
And you can select the input channel to output SDI embedded audio via 3.5mm headphone socket.





SDI Timecode, Channel Title

The SDI timecodes of each input channel can be displayed under HDMI multiview output. And you can also edit the channel title for each input video easily by pressing the keys on the front panel of S-9204.




Power Supply

The S-9204 can be powered via the 4-pin XLR socket of DC 12V input on the rear panel.
A 4-pin XLR power adaptor is provided in the product package.

Pure FPGA 10-bit Processing

Remain the original video colors

S-9204 adopts the pure FPGA chips to encode the original video; nothing is changed during the input and output with the 10-bit processing, which ensures the color reproduction of the original video


Strict Q-HD Quad-split

Get the most of video definition

The multiview mode strictly follows 1/4 or 1/16 of original video, which could help to get the most of the video definition, remain the original video quality of each input.

Video Formats

S-9204 supports the following video formats:
