This feature is useful for limiting the output of the source device to either 2 or multi-channel audio formats. NOTE: This selector switch will only affect the pre-programmed EDID in the INTERNAL (INT) EDID Mode. The GefenToolBox 1:4 Splitter for HDMI can use either of the following settings for audio format support: 1. 2 Channel: This setting will limit the audio formats listed in the pre- programmed EDID to 2 channel LPCM. For a full listing of the audio formats in this mode please see page 10. To use this mode, set the Audio Selection Switch on the front panel to the 2 CH position. This mode is useful in scenarios where all output devices/displays are HDTV monitors that only support 2 channel LPCM. This setting will ensure that all connected devices will receive and produce sound. 2. Multi-Channel: This setting will enable all common audio formats in the pre- programmed EDID. For a full listing of the audio formats in this mode please see page 10. To use this mode, set the Audio Selection Switch on the front panel to the Multi CH position. This mode is useful in scenarios where the output devices/displays are varying devices (i.e. HDTV display and audio receivers). Please note that sound may not be heard from all output devices/displays if a shared common audio format is not used by the source device. 8 EDID MANAGEMENT External EDID Management The GefenToolBox 1:4 Splitter for HDMI features EDID Management. Before the source can send video or audio signals to the display, the source devices reads the EDID (Extended Display Identification Data) of each device connected to an output. The EDID contains information about what type of A/V data that the source can send to each display. GefenToolBox 1:4 Splitter for HDMI distributes a single source to multiple output devices. This involves reading EDID data from more than one device. Management of the EDID data is important to maintain compatibility between all devices. Display Connections • If a display is not connected to Output 1, then no EDID changes are made, meaning that the previous EDID information will be used. This state will be in effect until a display is connected to Output 1 and the Splitter is power- cycled. • EDID is copied from Output 1 to all other outputs. The audio block will be copied from Output 1. EDID-copying is performed only when the Splitter is reset or power-cycled. 3DTV Support • 3D signals are supported if a 3DTV is connected to Output 1. Deep Color • Deep Color will be disabled if one of more other displays connected to the Splitter do not support Deep Color. 9 EDID MANAGEMENT Internal EDID Specifications The table below lists the settings that comprise the built-in Internal EDID data structure: Video Data Block Audio Data Block Speaker Allocation xvYCC 1080p@60Hz 2-channel: 2-channel: xvYCC 709 1080p@50Hz LPCM 2CH FL/FR xvYCC 601 1080i@60Hz (native) 1080i@50Hz Multi-channel: Multi-Channel: LPCM 2CH LPCM 8CH AC-3 6CH DTS 7CH Dolby Digital+ 8CHDolby TrueHD 8CHDTS-HD 8CH MAT(MLP) 8CH RLC/RRCRL/RRFC LFE FL/FR 10 FAST SWITCHING TECHNOLOGY FAST SWITCHING TECHNOLOGY Fast Switching Technology Fast Switching Technology (FST) is a Gefen software implementation for HDMI 1.3 products. FST was created to improve the inherited lengthy HDMI authentication process, based on the HDMI and HDCP specifications. FST provides quicker A/V source switching and greatly improves the overall A/V system behavior and performance when more than one HDTV display is used in the system setup. FST allows connecting / disconnecting or turning ON / OFF of HDTV displays without having these activities affect other Hi-Def sources routed to any other HDTV display in the same system. 11 WALL MOUNTING INSTRUCTIONS The GefenToolBox 1:4 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. For installation on a drywall surface, use a #6 drywall screw. It is recommended when installing on a drywall surface that studs be used to secure the Splitter should undue stress be applied when connecting and disconnecting HDMI cables. 12 SPECIFICATIONS Single Link Bandwidth ............................................................................. 225 MHz Pixel Clock / Speed .................................................................................. 165 MHz Maximum Video Resolution ................................... 1080p, 1920x1200@60Hz, 2K Input Video Signal .............................................................................. 1.2 volts p-p Input DDC Signal ......................................................................... 5 volts p-p (TTL) HDMI Input Connector .......................................................... type A 19-pin, female HDMI Output Connectors ............................
