English iRig Pro DUO LEDs The four LEDs on iRig Pro DUO 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 will show the audio signal level and the status of the unit as follow: • Both LEDs Off: iRig Pro DUO is not connected to any power source. • Both LEDs Dark blue: iRig Pro DUO is connected and in standby mode. • Ch.
English MIDI LED • Off: iRig Pro DUO is not receiving any MIDI messages. • Blinking Blue: iRig Pro DUO is transmitting MIDI messages. • Blinking Red: iRig Pro DUO is receiving MIDI messages. Direct monitoring When recording an audio signal into your audio software, there is often a slight delay before it reaches the outputs of the software and iRig Pro DUO. This delay, called latency, is caused by the computer processing required to convert and record audio.
English Dynamic microphones Before connecting dynamic microphones make sure phantom power is turned OFF. Check that the Phantom Power switch is in the OFF position and that the Phantom LED is turned off. Condenser microphones Most condenser microphones require external phantom power. If phantom power is ON, switch it OFF, and then connect your microphone. Turn phantom power ON only after the microphone is connected.
English Ribbon microphones Before connecting a ribbon microphone, turn OFF phantom power and check the microphone’s operating instruction manual to see if it requires it. Most ribbon microphones don’t require phantom power, and some can even be damaged by it. If you’re in doubt just leave it OFF. If the microphone won’t work, check its user manual, it may need phantom power. Please note that when +48V phantom power is turned on, it works on both channels simultaneously.
English Connecting instruments Connect your guitars, basses or any other mono instruments to the instrument inputs on iRig Pro DUO using an 1⁄4” plug unbalanced (TS or “mono”) guitar cord. IMPORTANT: the instrument input on iRig Pro DUO will NOT work if a cable with balanced (TRS or “stereo”) 1⁄4” plug is used. NOTE: In your audio software, select the appropriate iRig Pro DUO input (1 or 2) as the source of the track you will be recording to.
English MIDI OUT • Connect the 2.5mm-to-MIDI cable to the iRig Pro DUO MIDI OUT port and to the MIDI IN port on, for example, your sound module. • Open a Core MIDI compatible application on your iOS device or on your computer. • When iRig Pro DUO is sending MIDI messages the MIDI LED will blink blue. Setting input gain on iRig Pro DUO When talking or singing into your microphone, or when playing your instrument, check the audio level/status LED of the corresponding channel on iRig Pro DUO.
