Key Features
- 3-CHANNEL ROUTING & SMART PANNING: Engineered as a dedicated line-level audio mixer, it features 3 independent input channels. Toggle between Stereo and Mono modes with a long press of the channel button. In Mono mode, the smart panning function automatically assigns channels to Left, Center, and Right positions to create a structured stereo image. CRITICAL NOTE: It does not provide phantom power and DOES NOT support microphones
- DUAL OUTPUTS & DIRECT-COUPLED DESIGN: Driven by dual 97220 chips, this unit performs reliably as a gaming audio mixer or studio routing hub, providing two independent outputs for simultaneous headphone monitoring and recording. The capacitor-free, direct-coupled output design prevents phase shifts and completely eliminates low-frequency signal loss. Separate dials allow precise volume control
- PURE ANALOG CIRCUITRY & ZERO LATENCY: Designed to route sub-mix signals seamlessly into your primary mixer audio interface, the pure analog architecture delivers real-time processing with absolute zero latency. It maintains a linear frequency response of 20Hz40kHz (0.5dB). Built-in ground loop isolation circuitry effectively minimizes background noise floor for pristine signal transmission
- CLIPPING PROTECTION & MEMORY FUNCTION: Visual LED clipping indicators warn of signal overload in real-time to prevent sound distortion. The electronic power switch eliminates mechanical pop noises during startup. Additionally, a built-in memory chip automatically saves your last routing settings (Stereo/Mono) for instant plug-and-play operation upon restart
- COMPACT FOOTPRINT & PACKAGE CONTENTS: Measuring just 3.2 inches x 1.7 inches x 0.6 inches, this mini audio mixer is a space-saving portable audio mixer for mobile rigs. Powered via standard 5V USB, it integrates easily as an audio mixer for pc setups. INCLUDES: 1x Audio Mixer, 1x USB Power Cable, 1x 3.5mm Cable, 1x 1/4 inch Adapter. (WARNING: USB port is strictly for power supply, NOT a sound card. Power adapter NOT included)
- VERSATILE AUDIO ROUTING SOLUTION: Functions as a sub-mixer for synthesizers, keyboards, gaming consoles, and streaming setups, allowing seamless integration of multiple audio sources into your main audio interface or recording system
