In this example, we first change the trim level on Input 3 to be a level of 85. Entering “TRIM”
and a carriage return will display the trim levels of all inputs. In this case, we can see that the
trim level for Input 3 has be set to 85.
Audio Line Input Mix Audio Line Input Mix
To change the relative mix or audio level of the line input in relation to the HDMI extracted
audio, use the LIN command. For example:

Firmware Revision 1.0
$ LIN 80
LIN 80
In this example, stereo line input’s volume level is increased (from the default value of 70) in
relation to the audio extracted from the current HDMI input selected. Installations which use
this feature for a teacher microphone may want their voice louder.
A LIN value of zero will effectively mute the stereo line input and not affect the loudness of the
HDMI input selected.
Type “LIN” and carriage return to obtain the current LIN value.

input device then adjusts it’s output resolution to match the resolution of the display.
The SW1900-HD has the ability to intercept the input device’s request for display information
and respond with a user defined resolution. The command to specify this resolution is the RES
command and below is a list of RES settings:
