4-Channel USB Audio Mixer with Bluetooth, 48V Phantom Power & FX
A four-channel mixer that fits on a desk and still covers the whole signal chain: two mic/line combo inputs with 48 V phantom power, a stereo line channel, a built-in USB audio interface, Bluetooth and USB playback, and MP3 recording to a USB stick. Each channel gets its own gain, two-band EQ and fader, and a MAIN fader sets the overall level, so podcasting, streaming, home recording and small live events all run from one compact box.
Key Features
- 2 Mic / Line Inputs with +48 V — Combo XLR/TRS jacks on CH1 and CH2 accept a condenser or dynamic mic, a DI box or a line source, with switchable phantom power and PAD.
- Stereo CH3/4 Line In — RCA and 1/4 inch inputs take a keyboard, media player or phone, so four sources can be mixed at once.
- USB Audio Interface — Plug the mixer into a computer for recording and streaming without a separate interface.
- Bluetooth / MP3 Playback and USB Recording — Stream from a phone over Bluetooth, play from a USB drive, and record the mix straight to a USB device as MP3.
- Built-In FX — A per-channel FX switch feeds the onboard effect section, with DELAY and REPEAT knobs to dial in reverb-style depth.
- Gain, 2-Band EQ and Faders — Up to +60 dB of mic gain, +/-15 dB HIGH and LOW shaping and a smooth fader per channel give you a full mix surface in a desk-sized box.

Care & Usage
- Leave +48 V switched off for dynamic microphones and line sources, and enable it only for condenser microphones that need phantom power.
- If a PK indicator lights on CH1 or CH2, engage the PAD switch or lower the gain knob before bringing the fader up.
- Keep the channel and MAIN faders out of the top of the CLIP range; use the MAIN fader for overall level and the channel faders for balance.
- Keep the unit dry and do not open the chassis - there are no user-serviceable parts inside.
