Roland GO:MIXER PRO-X USB Audio Interface

Roland GO:MIXER PRO-X — Compact Audio Mixer and Interface for Smartphone Creators

Roland GO:MIXER PRO-X is a palm-sized 11-channel audio mixer and audio interface built for musicians, podcasters, and livestreamers who capture content on a phone or tablet. It accepts instruments, microphones, and stereo line sources at the same time and pre-mixes them into a single stereo feed that is instantly ready for any streaming or recording app. This model is the right choice for creators who want professional audio quality without hauling a full studio rig on location.

Standout Features That Set It Apart

What makes this mixer unusual in its category is the combination of a switchable +48 V phantom-powered XLR combo mic input, a dedicated high-impedance Guitar/Bass input with PAD attenuator, and a Loop Back switch that captures device playback alongside live sources in one stereo file. The headphone/headset jack doubles as a second mic input, allowing a co-host to plug in a headset mic or smartphone earbuds for interviews and talk-show formats.

Inputs and Connectivity — Plug-and-Play With Any Mobile Setup

Connectivity is the heart of any mobile mixer, and the unit is built to handle a full band, a podcast panel, or a solo creator without adapters. Eleven physical inputs cover every common source, while the included cable bundle removes the usual phone-to-mixer compatibility headaches.

• The number of channels is 11 input / 3 output, providing enough headroom for a small ensemble, a duo, or a multi-source podcast.
• Inputs: 6.3 mm jack (instrument L/R + Guitar/Bass), XLR/TRS combo mic, 3.5 mm stereo Line In 1, 3.5 mm stereo Line In 2, 3.5 mm TRRS smartphone in/out — covers electric and acoustic instruments, dynamic and condenser mics, plus media players
• Headphone Output Port: 3.5 mm TRRS stereo, supports headset mic passthrough — lets a second voice join via earbuds or a headset

Power, Portability, and Battery Life

For creators who shoot outdoors, stream from venues, or travel with their setup, power options and physical size matter as much as the spec sheet. The unit weighs only 215 g and runs from USB bus power or AAA batteries, so it slips into a daypack and works anywhere a phone works.

• Power Supply: USB bus power or 4 × AAA alkaline / Ni-MH batteries — choose cable-free operation or draw power from the host device
• Battery runtime is approximately 4 hours on alkaline AAA, which comfortably covers a typical livestream or rehearsal session.
• Dimensions: 104 × 155 × 41 mm — palm-sized footprint that fits next to a phone on a small desk or tripod rig
• Weight: 215 g (excluding batteries and cables) — light enough to carry in a jacket pocket

Audio Quality, Phantom Power, and App Compatibility

Audio performance is where this instrument earns its place above basic phone-mic setups. Switchable phantom power lets users run a condenser microphone for broadcast-quality vocals, while the dedicated Guitar/Bass PAD switch keeps hot pickups from clipping the input stage.

• Phantom Power: +48 V switchable on the XLR combo mic input (DC 48 V, 6 mA max) — supports condenser microphones for studio-style vocal capture
• Loop Back Function: on/off switch routes device playback into the mix — record play-along videos with backing tracks from the phone's library
• Package Content: manual, Lightning to USB Micro-B cable, USB-C to USB Micro-B cable, 3.5 mm TRRS audio cable — works with most current iOS and Android devices straight out of the box
• App Compatibility: native support for Roland 4XCAMERA and Virtual Stage Camera apps, plus music apps like Zenbeats and GarageBand — ready for music videos, livestreams, and mobile production
