Setting Description
Treble Sets the volume level for high frequencies without
changing the master audio volume.
Output Mode Specifies how the system configures the volume for
a device connected to the line out port.
▪ Variable: Enables users to set the volume with
the remote control.
▪ Fixed: Sets the volume to the audio level
configured for the system.
Audio Meter (dB) Displays the audio level of the output (left and right
channels).
Using 3.5 mm Audio Output
If you want to use the 3.5 mm stereo line output to hear audio in the room, make sure you mute the
monitor(s) connected to your G7500 system through HDMI.
