Information about the amplifi er is stored in the software 
system inven tory and is displayed on the software 
control panels. Information includes manufacturer, 
model, date code, and serial number. The green items 
can’t be edited. 

Channel Labels: Each amplifi er includes two labels 
that you may edit for your own use. Simply type in the 
text areas. Use these labels to describe the channels of 
your amplifi er. These names will appear in the individual 
processing blocks.

Attenuator Limits: This lets you set a limit on the 
attenuators. You can set the maximum attenuation from 0 
dB to –100 dB. Once set, attenuation cannot be adjusted 
beyond this level.

NOTE: The attenuator setting must be below the 
attenuator limit that you are trying to set. For example, if 
the attenuator is set at –3 dB, you cannot set the 
attenuator limit below –3 dB unless you decrease the 
attenuator level.

Blackout Mode: This button lets you blackout the front 
panel display until you press a front-panel button or turn 
an Encoder. This feature turns off the LCD backlight and 
all front panel LEDs except for the fault LEDs and power-
switch green LED. After blackout mode is enabled, an 
Encoder press/turn will “reactivate” the display. If no 
button is pressed/turned for over 5 seconds, the display 
will return to blackout mode.

This screen lets you apply the System Architect settings

Due to the nature of DSP processing, there is some inherent delay or latency within 
the I-Tech’s DSP. These latencies are shown in Table 4 below:

These latencies do not include CobraNet Transport Latency and FIR Processing 
Latency.
