CHAPTER 2

The SIM 3 Hardware

2.2.2. LED Indicators

2.2.2.1. Console/Processor

These indicators show the conﬁguration made in the software (from the Branches dialog,

select the Switchers tab) of the line switcher for the ﬁrst eight channels in groups of four.

When the console LED (left) is lit, those four channels become system input channels (From

Console). When the processor LED (right) is lit, those four channels become processor output

channels (From Processor).

2.2.2.2. Bus Select

There is one blue LED for each channel of the switcher. The LED, when lit, indicates that the

channel is assigned to one of the buses in the Live Branch.

NOTE: The level of the selected channels can be monitored in the SIM-3022

analyzer. The front-panel Line 1 meter will show the level of the signal on the

“console” bus and the Line 2 meter will show the “processor” bus of the Live Branch.

2.2.2.3. Mute

There is one bi-color (green and red) LED for each channel on the switcher. These LEDs

indicate the status of the channel as follows:

■ Off – Indicates the channel is used as a system input (From Console)

■ Green – Indicates the channel is used as a processor and its output (To Speaker) is

passing signal (not muted)

■ Red – Indicates the channel is used as a processor and its output (To Speaker) is muted

Only channels 9 - 16 can mute in every conﬁguration, and channels 1 - 8 need to be

conﬁgured from the software as “processor” in groups of four to be able to mute.

NOTE: If the mute safe switch is set to “Enabled,” muting can only be

accomplished via the software (in the selected channel located on the right

side of the screen under the Speakers tab).
