cooidea A04 2-Channel Stereo Mini Audio Mixer 48 kHz USB 3.5 mm

Compact stereo mixer for two sources

The cooidea A04 is a palm-sized stereo mixer that merges two 3.5 mm inputs into one headphone or speaker output. USB power makes it plug-and-play with any DAW and it runs continuously at ultra-low consumption. The 97220 chip and capacitor-free design deliver 125 mW into 32 ohms for clean, bass-rich sound from an aluminium shell measuring 33 mm x 28 mm x 13 mm.

Suited for simple desktop blending, not for mic work

Streamers, podcasters or mobile producers who need to hear a phone and a computer together will appreciate the zero-latency hardware sum. Buyers who require microphone preamps, phantom power, gain controls or multi-track recording should look elsewhere because this unit only accepts line-level stereo sources and provides no mic support.

Handles two line sources with 125 mW headroom

Each channel accepts a standard 3.5 mm stereo signal at 48 kHz and the combined output drives headphones or powered speakers up to 125 mW at 32 ohms. The mixer adds no processing, so dynamic range is limited by the source devices; it cannot amplify weak signals beyond the fixed gain stage and offers no EQ or level metering.
