Extron Electronics SSP 7.1 User Guide - Manual (Page 18)

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:

The analog input gain can also be controlled using the SSP 7.1 Setup and Control Software
(see
Master Volume and Mute on page 29).
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 Front Panel
on page 52).
