EDID MANAGEMENT
Audio Channel Selection
The GefenToolBox 1:4 Splitter for HDMI with FST features a switch that will
modify the supported audio formats listed in the pre-programmed EDID. 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 with FST 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. See page 11 for a full listing of the
audio formats in this mode.
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
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. See page 11 for a full listing of the audio formats in this
mode.
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.
