Definitions
The following terms apply to Extron Matrix Switchers, and are used throughout
this manual:
Tie — An input-to-output connection.
Configuration — May consist of one tie or two ties.
Current configuration — The configuration that is currently being used (also
called configuration 0).
Input buttons, output buttons, and LEDs
1 Input 1 through 4 buttons and LEDs — The Input buttons are used to select
an input, either to determine existing ties, or to set up a configuration. The
input LEDs identify selected inputs and indicate audio levels in the audio
adjustment mode. A more detailed explanation of the two functions is
included in Front Panel Operations later in this chapter.
2 Outputs button and Outputs 1 and 2 LEDs — The Outputs button and LEDs
select and identify outputs.
I/O Control buttons and LEDs
When creating or viewing a configuration, you must specify whether the
configuration applies to video, audio, or both. This is done with the Conf/Save
button. Current mode is indicated by the Audio and Video LEDs.
3 and 4 Decrement ▼ ▼ ▼ ▼ ▼ and Increment ▲ ▲ ▲ ▲ ▲ buttons and LEDs — The Decrement
▼ and Increment ▲ buttons decrease and increase the amount of audio gain
for a selected input. The input 1-4 LEDs and the Decrement ▼ and Increment
▲ LEDs indicate the audio level of the selected input (see the chart in Viewing
and adjusting the audio level).
5 I/O Conf/Save button and LED — Press and release the Conf/Save button to
select video and audio, video only, or audio only for configuration. As a
secondary function, the Conf/Save button selects the audio level display/
adjust mode. Press and hold the Conf/Save button until the I/O LED begins
to blink. If the Video/+dB LED was lit, it turns off. Select an input. The
current audio level setting for the selected input is displayed in the input
LEDs. The audio level for the selected input can be increased or decreased by
pressing the Increment (3) or Decrement (4) buttons. A more detailed
