System Info
The System Info menu provides the following statistics:
• Firmware Version
• CPU Usage – Normally around 20%
• Buffer Size
• Average SR – Average Sample Rate
• Samples Processed – This is a useless (but fun) statistic
4.1.4
System Options
The System Options menu provides the following functions:
• Master Bypass – Relay bypass of Digital Inputs to Digital Outputs
• LCD Shutoff – Select the time-out for the LCD backlight. The backlight turns
on once any control is pressed. The unit ships with a 15 minute setting to prolong
the life of the backlight tube. Although the unit is rated for long life, it will not
last forever and the entire costly LCD display must be replaced when it fails. We
like the light show and the meters and have not had a display fail in three years
of almost constant use, but we are being respectful of our customer's budgets!
• Reinitialize – Fast reset of the system software and audio drivers.
• Save Settings Immediately - In an effort to minimize any slgiht audio clicks, the
unit will save changes over a period of time, usually several minutes. Pressing
Save Setting Immediately will bypass this feature and write the changes immedi-
ately and usually without any audible side effects. It may still take up to a minute
for the buffers to completely flush.
• Power Cycle – Slow reset of the entire system. Select this to perform a full sys-
tem re-boot and re-initialize; you are returned to the main menu. This is a very
useful way to guarantee all current settings are saved immediately and the unit is
re-booted, re-sychronized, and started fresh. Note that this operation may take
up to 3 minutes.
