Inputs
The input cards available for the Quantum Ultra Series include:
•
HDMI (IN4HDMI)
— Each card contains four HDMI connectors.
•
HDMI 4K PLUS (IN4HDMI 4K PLUS)
— (Quantum Ultra II models only) Each card
contains four HDMI connectors that support resolutions up to 4096x2160 @ 60 Hz.
They also pass through audio signals that are embedded on the HDMI output.
•
IP (IN SMD 100)
— Each card contains two LAN connectors.
Source down-scaling
Each input card has an on-board scaler that can down-scale the video sources in size to
1/32 of the original size (horizontally, vertically, or both). Production of up to 16 instances
of an input is supported, up to the total bandwidth of 18 Gbps (4K @ 60 Hz) or 144 Gbps
(8 x 4K @ 60 Hz) for 4K PLUS cards.

Should more instances be required for a preset layout, the scaler produces the required
image sizes but reduces the frame rate as needed.
Downscaling examples
For simplicity, the example in the diagram in figure 9 assumes that each screen in the
target display has the same resolution as the source.
