Professional Audio Mixer 4-Channel Unpowered Mixer - Flexible Playback

In this review of the Professional Audio Mixer, the bottom line is straightforward: this compact, unpowered 4-channel console is aimed at small studios, streamers, and karaoke hosts who need flexible playback and reliable mic support without a large footprint. The reviewer found the strongest reason to buy is the combination of multiple playback options - built-in MP3 player, USB drive slot and stable Bluetooth - paired with switchable XLR/LINE inputs and +48V phantom power, which together make it a practical all-in-one desk mixer for recording sessions and live streaming setups.

Key Features

• Versatile Playback: Built-in MP3 support, a USB drive slot and Bluetooth let users queue background tracks or intros without extra players.
• Four Individual Channels: Four inputs with dedicated level controls make it simple to mix multiple microphones or line sources for performances or podcasts.
• REC Output: A REC OUT jack gives a direct output for easy recording of sessions or sending a clean feed to another device.
• +48V Phantom Power: Switchable phantom power supports condenser microphones and boosts vocal clarity for studio and live use.
• 2-Band EQ Per Channel: High and low EQ knobs on each channel allow real-time tone shaping to suit voices and instruments.
• Built-In Digital Delay: Onboard delay effects add depth for karaoke, streaming and small stage use without external processors.

Who It's For

The mixer is best for solo streamers, podcasters, small rehearsal rooms and KTV hosts who want a compact desk solution with flexible playback and mic compatibility. Its USB and Bluetooth playback options are handy when you need to play backing tracks from a phone or drive without a laptop.

It is less suitable for large live bands or installations that require many channels, powered outputs, or integrated multitrack USB recording. Users who need extensive onboard processing or a high channel count should look at larger consoles or powered mixers instead.

Pros & Cons

Pros

• Multiple playback choices (MP3, USB drive, Bluetooth) reduce setup complexity for shows and streams.
• Switchable XLR/LINE combo jacks with +48V phantom power support both dynamic and condenser microphones.
• Per-channel 2-band EQ and built-in digital delay provide useful tone control and effects without extra gear.
• REC OUT makes it easy to capture a direct mix for recording or archiving sessions.

Cons

• As an unpowered mixing console, it lacks built-in amplifiers or high channel counts for larger live rigs.
• Two-band EQ and single effects type may be limiting for users wanting more advanced DSP options.
