The LED bar lights from the bottom up to indicate the current gain level. No LEDs lit indicates
no gain (0 dB, or unity gain); all the LEDs lit indicates maximum gain (24 dB). Each solidly lit LED
represents 3 dB. A slowly blinking LED indicates an additional 1 dB or a quickly blinking LED
indicates an additional 2 dB:

Front Panel Security Lockout (Executive Mode)
When the front panel is locked, the user cannot make any changes from the front panel (except
disabling the security lockout). If the user attempts to make changes with the front panel locked
out, all the input LEDs flash simultaneously. The lockout does not block changes made using SIS
commands or the SSP 7.1 Setup and Control Software. To lock out the front panel:
1. Press and hold the active input button (the button next to the LED that is lit).
2. While holding the active input button, press and hold any other input button. All the LEDs
blink in ascending order (from 1 to 5) and then the active input button lights.
3. The front panel is unlocked in exactly the same way. All the LEDs blink in descending order
(5 first and 1 last) and then the active input button lights.
This feature can also be set using the SSP 7.1 Setup and Control Software (see
page 46).
