iRig USB
Thank you for purchasing iRig USB.
Your package contains:
• iRig USB
• USB cable
iRig USB is the new entry of the iRig guitar interface family. This new iRig interface is packed in an all-new
enclosure and sports some new important features.
We still find all the I/Os that are made of the iRig interfaces the first choice for on-the-go guitarists: one 1/4
inches instrument input with dedicated gain control, a 1/4 inches Amp output with dual mode operation, and a
1/8 inches headphone output.
The Amp out can work in two modes: you can set the AMP out jack to carry the signal (processed), coming out
from your device, back out to an instrument amplifier. Or, you can set the AMP out jack to carry the same signal
that is put into the Instrument input. This mode is typically used to send the instrument signal that is plugged
into the Instrument jack back out to an instrument amplifier or other unbalanced input.

2. Gain knob - This knob controls the level of the input signal.
3. Instrument input - 1/4” (6.35mm) jack type - Connect your instrument here (e.g., guitar).
4. Amplifier output - 1/4” (6.35mm) jack type - You can connect an external amplifier to iRig USB thanks to
the “Amplifier output jack”. This allows you to send the processed signal (i.e. from a rig inside your mobile
device) or a direct unprocessed signal, out to your amplifier or other unbalanced input.
5. FX/THRU switch - This switch allows you to select the type of output that is sent thru the “Amplifier output
jack.”
6. Headphone output - 1/8” (3.5mm) jack type - connect here your headphones.

2. Installation and setup
2.1 Setup
1. Connect the included USB-C cable to the iRig USB.
2. Connect the cable to the host device.
3. Connect your guitar, bass or other mono instrument to the 1/4” input jack on iRig USB.
4. Launch your preferred audio App and set iRig USB as your default audio device. To do so, please refer to
the documentations of the App or Software you’re using.
5. Connect your headphones, mixer or powered speakers to the iRig USB headphone jack. You can control
this level with the host’s volume control.
6. Connect an external amplifier to the 1/4” TS Amplifier output jack on iRig USB and select the type of signal
sent to the output with the FX/THRU switch.
3. iRig USB status LED
The LED on iRig USB gives you important information about the iRig USB’s operative status.
•LEDisoff: iRig USB is not connected to any power source.
•LEDisblue: iRig USB is connected and active.
•LEDisred: iRig USB is active and the input signal is too high.
4. Setting the input gain
When playing your instrument check the iRig USB status LED. If the LED is sometimes flashing RED you should
decrease the iRig USB input gain by rotating the GAIN knob CCW (counter-clock wise).
You can check the optimal input level within the audio software you’re using.
5. Amplifier output jack
You can connect an external amplifier to iRig USB thanks to the “Amplifier output jack”. This allows you to
send the processed signal (i.e. from a rig inside your mobile device) or a direct unprocessed signal, out to your
amplifier or other unbalanced input.

5.1 FX/THRU switch
THRUFX
The THRU-FX switch allows you to select the type of output that is sent thru the “Amplifier output jack.”
When this switch is set to THRU, the “Amplifier output jack” carries the same signal that is sent to the
instrument input. This mode is typically used to send the dry instrument signal back out to an instrument
amplifier or other unbalanced input. This lets you plug your favorite amplifier into the “Amplifier output jack” and,
at the same time, connect iRig USB to your mobile device that runs. For example, a tuner app or your favorite
recording app. The headphone out lets you listen to the processed output of your device.
When this switch is set to FX, the “Amplifier output jack” carries the processed signal from your mobile device
to an instrument amplifier. This lets you process your instrument inside your favorite app and then send it to, for
example, an amplifiers clean channel.
6. Headphone output jack
The 1/8” headphone output lets you conveniently monitor the signal coming from your device. This output works
seamlessly in both switch positions (Thru-Fx). It is also possible to adjust its volume with the connected host
volume control.

7. Troubleshooting
Sound is distorted.
Check that the input gain on iRig USB has been set properly. If the LED is red when you play your instrument,
decrease the input gain as described in this guide.
No sound is playback thru the connected headphones nor to the Amp out when in FX mode.
Use the volume control on the connected host to set the volume of the headphone output and FX out.
