The Roland GOMIXERPX, also known as the GO:MIXER PRO-X, is a compact and highly portable audio mixer specifically engineered to enhance the audio recording and live streaming capabilities of smartphones and tablets. It functions as an external, hardware-based audio interface that allows users to connect multiple professional audio sources directly to their mobile device, bypassing the limited built-in microphone to achieve studio-quality sound for content creation. The mixer is designed around a simple, intuitive layout with dedicated volume knobs for each input channel, enabling real-time level adjustment and balancing. This is particularly valuable for musicians, podcasters, vloggers, and live streamers who require high-fidelity, multi-source audio in dynamic, on-the-go situations.

The unit features a versatile set of inputs, including combo XLR/TRS jacks that accept both microphone and line-level signals, and a dedicated 1/4-inch instrument input for connecting guitars or keyboards directly. These inputs provide switchable phantom power for condenser microphones, ensuring compatibility with a wide range of professional audio gear. A key design aspect is its ability to mix all connected sources into a single, clean stereo output that is sent to the mobile device via a standard TRRS cable (included) compatible with most iOS and Android phones and tablets. This integrated mix includes a dedicated channel for monitoring the device's own playback audio, allowing users to hear backing tracks or game audio in their headphones while recording a voiceover or performance.

Built for durability and portability, the GO:MIXER PRO-X is powered directly by the connected mobile device, eliminating the need for external batteries or power supplies. Its rugged metal chassis and straightforward, knob-per-function design make it exceptionally user-friendly and reliable in field recording scenarios, from recording song ideas and podcast interviews to broadcasting live gameplay commentary. By providing professional audio connectivity, mixing, and control in a pocket-sized format, it effectively transforms a smartphone into a powerful mobile production studio.
