LED Indicators
The LED display panel provides information about the operating status and also helps
you adjust microphone and instrument levels.
Level Adjustment with four LED sets
Four ‘traffic-light’ LED sets indicate the level of the recording channels 1-4. Every set of
LEDs is numbered: set 1 and 2 correspond to mic and line inputs 1 and 2, while set 3
and 4 correspond to instrument and line inputs 3 and 4.
• The OVL LEDs light red to indicate that the Crimson’s AD-converter is being overloaded.
As a safety measure, the OVL LEDs have a peak hold for one second.
• The -6 (dB FS) LEDs light yellow. An optimally adjusted level makes it go on and off
from time to time.
• The SIG LEDs light green and indicate the presence of a signal.
Status-LEDs
• The PWR LED indicates the power supply of the unit.
• The Host LED indicates that a host computer or iPhone/iPad has been detected at
the USB port and the connection has been correctly established.
• The Midi In LED indicates data flow on the Midi input.
