Fender Mustang GTX50 GTX100 User Manual AUXILIARY AND HEADPHONE JACKS

The Mustang GTX control panel features two 1/8”-inch jacks—an auxiliary input for connecting external mobile/audio devices and an output for convenient headphone use.

Note that when using the auxiliary input, volume levels for external devices are set using volume controls on the external devices themselves, or by using the Mustang GTX “BT & AUX VOLUME” menu function described on page 36. Also note that when headphones are plugged in, speaker output is muted.
