QuattroI/Ousingan1⁄4”plugunbalanced(TSor“mono”)guitarcord.
NOTE: In your audio software, select the appropriate iRig Pro Quattro I/O input (1 or 2) as the source of the track
you will be recording to. Adjust the channel gain knob until you have sufficient audio signal without clipping.
9 Connecting line level signals
It is possible to connect balanced (1/4” TRS) or unbalanced (RCA or 1/8” TRS) line level signals to the inputs 3
and 4 of the iRig Pro Quattro I/O.
Gain knobs 3 and 4 control only the inputs connected to the 1/4” TRS jacks.
We recommend to not connect all inputs (1/4”, RCA and 1/8”) simultaneously in order to minimise the noise floor
of the channels. Indeed, we recommend to use only one of the inputs at a time.
10 Connecting loudspeakers, headphones and other external devices
• Connect a pair of active studio monitors or an audio amplifier to the male 3-pin XLR connectors labeled Line
Out 1/L and 2/R. It is also possible to use the 1/8” TRS jack labeled Stereo that allows you to send the audio
signal to a video camera or other device while monitoring with headphones.
• Connect headphones to the 1/8” output jack and adjust its level via the headphone knob.
• Output levels can also be controlled with the host volume’s control.
