It offers four input channels, flexible connectivity, and built-in audio effects, making it a complete audio management solution in a portable form factor.

This mixer accommodates multiple audio sources simultaneously. It features two combined mono XLR/TRS inputs for microphones or line-level instruments, plus a stereo input for instruments, media players, or playback devices. The console supports phantom power (+48V) on the XLR inputs, enabling compatibility with condenser microphones.

One of the standout features of the A4 is its Bluetooth connectivity, which allows wireless audio streaming from smartphones, tablets, or laptops. This is ideal for background music, playback tracks, or on-the-fly setups without cables. Additionally, the mixer doubles as a USB audio interface, enabling direct recording or streaming from a computer. It also supports audio playback and recording from USB flash drives, making it a versatile solution for both digital and analog workflows.

Each channel comes with input gain control and a 3-band equalizer (High / Low), allowing precise sound shaping. The mixer includes built-in DSP effects like reverb and delay, enhancing vocals or instruments and providing professional-sounding audio for live or recorded sessions. Monitoring is straightforward with a dedicated headphone output, while main outputs connect to speakers, amplifiers, or PA systems. Auxiliary output and recording output further expand the mixer’s capabilities.

A4 is designed for both portability and durability. Its lightweight and compact body makes it easy to transport for live events, studio sessions, or mobile setups, while its robust construction ensures longevity. The console is perfect for streamers, podcasters, musicians, singers, DJs, and anyone requiring a compact, reliable audio mixer for small-to-medium-scale projects.
