Figure 2.6. SIM-3088 front panel LED indicators for an 8+8 configuration
The Mute/On LEDs for channels 9-16 will be lit either green or red, since channels 9-16 are
always used as processor and are either passing signal (green) or muted (red).
2.2.3.2. 4+12 Configuration
In this configuration, the switcher uses four channels as system inputs (From Console) and
12 channels as processor outputs (To Speaker).
Transfer function measurements are made in the same manner as the 8+8 configuration
discussed above.
As shown in Figure 2.3, this configuration will light the Console LED for channels 1-4, while
the Processor LED for channels 5-8 will be lit. The mute/ON LEDs (1-4) will be off and the
mute/ON LEDs (5-8) will be lit either green (passing signal) or red (muted).
