EDID MANAGEMENT

Audio Channel Selection

The GefenToolBox 1:8 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 1:8 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. For a full listing of the audio formats 
in this mode please see page 11.

To use this mode, set the Audio Selection Switch on the front panel to the 

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 11.

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 (e.g. 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.
