4-SDI Quad Viewer

The S-9104 is the SDI Quad Viewer of 4 SDI input, and output HDMI or SDI in quad split display mode, which is widely used in broadcast studios to monitor 4 SDI signals by 1 HDMI television.
It’s 19-inch 1U designed, and can be installed in standard broadcast racks.



Input and Output

S-9104 Quad Viewer supports:
HD/SD-SDI input ×4
HD/SD-SDI loop output ×4
HDMI Quad-split output ×1
HD/SD-SDI Quad-split output ×1
3.5mm analog audio output ×1


HD / SD Mixed Inputs

Currently quite a few of broadcast studios produce both HD and SD programs, and S-9104 Quad Viewer supports HD-SDI and SD-SDI mixed input and quad-split output via SDI or HDMI.
The mixable formats are: SDI 1080i50 with SDI 576i; SDI 1080i60 with SDI 480i. And the ratio of SD channel can be adjusted to 4:3



Full Screen Switching Display

Besides the Quad-split mode, you can also select 1 input channel to full screen display, and switch to other input channels conveniently by the pressing the buttons on the front panel of S-9104.


Embedded Audio Monitoring

By audio meters or headphone output

The Quad-split output or full screen switching output support 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.




UMD/TALLY and Alerting

S-9104 support UMD and TALLY display of TSL Protocal, and will alert "NO SIGNAL", "MUTE", "FROZEN FRAME" or "BLACK FRAME" when detected video/audio lost and any abnormal of input SDI signals.

Power Supply

The S-9104 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-9104 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 quad-split mode strictly follows quarter HD resolution, with 960×540 of each input video, which could help to get the most of the video definition, remain the original video quality of each input. Meanwhile, if the input video is SD-SDI, it will display pixel to pixel at the quad-split mode.

Video Formats

S-9104 supports the following SDI input formats:

(1) In the quad split mode, support 480i/1080i60 mixed input and 576i/1080i50 mixed input. For all the other formats, the quad split mode requires the 4 input SDI of the same formats.
(2) When input SDI is 720/1080, the SDI or HDMI output format is the same with input.
(3) When input SDI is 480i or mixed with 1080i60, the SDI or HDMI output format is 1080i60
(4) When input SDI is 576i or mixed with 1080i 50 the SDI or HDMI output format is 1080i50
