iRig Pro Duo I/O LEDs
The four LEDs on iRig Pro Duo I/O give you important information about the unit’s operative status. Each status
is indicated by a different color.
Status / Audio level LEDs
For each channel iRig Pro Duo I/O will show the audio signal level and the status of the unit as follow:
• Both LEDs Off: iRig Pro Duo I/O is not connected to any power source.
• Both LEDs Dark blue: iRig Pro Duo I/O is connected and in standby mode.
• Ch. LED Bright blue: iRig Pro Duo I/O is connected and a signal is present at the input of the corresponding
channel.
• Ch. LED Green: The input signal of the corresponding channel is low.
• Ch. LED Orange: The input signal of the corresponding channel is OK.
• Ch. LED Red: The input signal of the corresponding channel is too high.
Phantom and MIDI LEDs
The two upper LEDs show the phantom power and MIDI status.
Phantom LED
• Off: phantom power is OFF
• Flashing Blue: phantom power is powering ON. To avoid audio bumps iRig Pro Duo I/O is muted while
phantom power is turning ON, so it is normal to not hear any signal until this LED turns steady BLUE when
turning on +48V phantom power.
• Steady Blue: phantom power is ON
• Flashing Red: internal AA batteries are LOW! Before iRig Pro Duo I/O shuts down this LED will start blinking.
This means that the battery level is low and it should be replaced as soon as possible.
