Installation Cascading Splitters The 4K Ultra HD 1:2 Splitter for HDMI provides the capability to “cascade” (daisy-chain) up to 10 splitters.

WITCHING ECHNOLOGY Fast Switching Technology Fast Switching Technology (FST) is a Gefen software implementation for HDMI products. FST was created to improve the lengthy HDMI authentication process, based on the HDMI and HDCP specifications. FST provides quicker audio/video source switching and greatly improves the overall audio/ video system behavior and performance when more than one HDTV display is used in the system setup.
Setting the Switching Mode Using Slow Mode When set to slow switching mode, the 4K Ultra HD 1:2 Splitter for HDMI will follow the standard authentication process, based on the HDMI and HDCP specifications. Slow mode is recommended when the source does not support multiple devices. Out 1 Out 2 Disconnect the power supply from the splitter.
Setting the Audio Channel Mode The 4K Ultra HD 1:2 Splitter for HDMI features a switch that will switch between 2-channel and multichannel audio output. Information In order for the audio channel mode to be selected, the EDID switch must be set to the Int position. If the EDID switch is set to the Ext position, then the Audio switch will have no effect on the audio output signal.
Setting the Audio Channel Mode Out 1 Out 2 Using Multichannel Audio Use this audio mode when the connected displays (and/or other sink devices) are capable of supporting multichannel audio. Disconnect the power supply from the splitter. Fast Set the EDID switch to the Int (up) position. Slow Set the Audio switch to the Multi-ch (down) position.
Setting the EDID Mode The 4K Ultra HD 1:2 Splitter for HDMI features EDID Management. Before the source can send video and/or audio to the display (sink), the source reads the EDID (Extended Display Identification Data) from the display (sink) devices connected to the splitter. The EDID contains information about what type of audio/video data that the source can send to each output device.
Surface Mount Instructions The 4K Ultra HD 1:2 Splitter for HDMI should be mounted vertically in a wall or cabinet with wood/drywall screws as shown in the diagram above. There should be an inch or two of clearance between the edges of the unit and any walls or vertical surfaces to allow for enough clearance for insertion and retraction of cables at the HDMI connectors.
