LMIX1 4-Channel Stereo/Mono Audio Mixer with Volume Control and 1 Outputs

LMIX1 is a compact 4-in/1-out stereo mixer for dynamic mics, guitars, keyboards, and music players. Each channel features a mono/stereo switch, independent volume control, and an INPUT button to enhance mic performance. Isolated signal paths help avoid crosstalk and noise. Outputs include both 1/4″ or 1/8″ stereo jacks for flexible use. For best results, set input and output volume to 70% or above. Use only the included 12V power adapter. Not compatible with USB or condenser microphones.

Compatible Microphone Types

Supports wired and wireless dynamic microphones. For best results, set input/output volume to 70% or above.

Note: Wireless mics require a separate transmitter/receiver (not included). USB and condenser mics are not supported. Check mic type before purchasing.

Important Notice: DC 12V Power Adapter Update

Due to customer input, we’ve updated the DC 12V power adapter. Current stock may include either the old or new version, and we cannot specify which one will be shipped. If the old adapter doesn’t meet your needs, please let us know, and we will solve it promptly

Multiple Device Compatibility

This mixer supports a wide range of audio sources, including dynamic microphones, electric guitars, electronic drums, keyboards, and digital pianos. Ideal for live streaming, rehearsal, or personal music creation—please note it does not support condenser mics directly.

Simple Operation

1.Mono/Stereo Input Selection: Switch between Mono (TS) or Stereo (TRS) to match your device.

2.INPUT Button: Unique button ensures clear, noise-free audio with dynamic microphones, no extra adjustments required.

3.Independent Volume Control: Adjust each input’s level with 4 dedicated volume knobs.

Why should I press the input button for dynamic microphones only when no sound is being input?

If audio is actively being transmitted (e.g. someone is speaking or the mic is live), pressing the button may cause a loud noise or signal disruption. To avoid this, ensure the input is silent before switching modes.

What happens if I set the input or output volume too high or too low?

Setting the volume too high may cause distortion or overload. Too low can lead to weak output and background noise. For best performance, keep both input and output levels at 70% or above.

Is this mixer 4-in/1-out or 1-in/4-out? What does it mean?

This is a 4-in/1-out mixer, meaning it combines up to 4 audio input sources into a single mixed output. It does not support 1 input to 4 separate outputs.

Can I plug both a 1/4″ and a 1/8″ connector into INPUT 1 at the same time to connect two devices?

It is not recommended to connect both a 1/4″ (6.35mm) and a 1/8″ (3.5mm) plug into the same input channel at the same time. Doing so may cause signal interference or reduced audio quality. For best results, please use only one input type per channel.

My mixer has no sound output. How can I troubleshoot the issue?

Make sure the mixer is powered with the original adapter. Check input source, cables, and volume (set to 70%+). Match mono/stereo mode. Press the INPUT button for dynamic mics. Confirm output device is connected properly.

Note: If you experience any issues with the included power adapter, we will work to resolve them quickly and ensure your satisfaction.
