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.
