Roland GO:MIXER PRO-X Smartphone Audio Mixer

The Roland GO:MIXER PRO-X is a compact audio mixer designed to improve the sound captured by compatible smartphones and tablets. It lets creators combine microphones, instruments, line-level sources, and mobile-device audio into a single recording or stream. This makes it a practical alternative to relying only on a phone or tablet’s built-in microphone.

It is suited to musicians recording performances, podcasters, interviewers, educators, and live-streaming creators. Dedicated level controls help balance connected sources directly at the mixer while working alone or with other performers. The compact format supports mobile recording setups without requiring a conventional desktop mixer.

The GO:MIXER PRO-X provides 11 input channels and three output channels, with connections for a microphone, guitar or bass, stereo instruments, two stereo line sources, and a headset microphone. A combo XLR/TRS microphone input supports dynamic microphones and phantom-powered condenser microphones. The dedicated guitar/bass input supports high-impedance instruments and includes a selectable pad for active pickups.

For mobile-device connection, the mixer supports digital USB connection through its Micro-B USB port and analog connection through its CTIA TRRS smartphone jack. Included Lightning-to-Micro-B, USB-C-to-Micro-B, and 3.5 mm TRRS cables provide connection options for many iOS and Android devices. The Loop Back function can include playback from the connected mobile device in the recorded mix when needed.

Use the GO:MIXER PRO-X as a portable front end for video creation, live streaming, mobile music apps, practice, or simple location recording. Headphone monitoring and headset support make it useful for checking the mix while recording. It can operate from USB bus power or four AAA batteries, giving users a flexible path from a phone-based setup to a more complete mobile production rig.

Design & Installation

The GO:MIXER PRO-X uses a palm-sized, control-focused layout with dedicated knobs for instrument, guitar/bass, microphone, headset microphone, and headphone/smartphone output levels. A POWER indicator and PEAK indicator provide visual operating status. Roland does not specify the enclosure material in its published product specifications.

Connect instruments, microphones, and line sources before connecting the included USB cable to a compatible smartphone or tablet. Use the included Lightning-to-Micro-B or USB-C-to-Micro-B cable for digital connection where supported, or use the included 3.5 mm TRRS cable for analog CTIA connection. For condenser microphones requiring phantom power with an iPhone or iPad, install four AAA batteries in the mixer.
