5. Setup
5.1. Power Connection
- Connect the USB to Type-C power cable to the mixer's power input.
- Connect the other end of the USB cable to the provided 5V 2A power adapter.
- Plug the power adapter into a standard electrical outlet. The power indicator on the mixer will light up.
5.2. Wireless Microphone Setup
- Unscrew the bottom cap of each wireless microphone.
- Insert 2 x 1.5V AA batteries into each microphone, observing correct polarity (+/-).
- Screw the bottom cap back on.
- Press and hold the power button on each microphone to turn it on. The display will show the operating frequency.
- The mixer has a built-in receiver for these microphones, which are routed through MIC/LINE 2. Ensure the "MIC ON A" or "MIC ON B" indicator lights up on the mixer for the corresponding microphone.
- If interference occurs, use the frequency select switch (A/B) on the mixer to change the wireless microphone frequency.

6. Operating Instructions
6.1. Basic Operation
- Power On: Ensure all connections are secure, then connect the power adapter. The mixer powers on automatically.
- Initial Volume Settings: Before playing any audio, set all GAIN, LEVEL, and MAIN LEVEL knobs to their minimum positions to prevent sudden loud sounds.
- Adjusting Input Gain: For each active channel (MIC/LINE 1, MIC/LINE 2, 3/4 Channel, AUX, USB, Bluetooth), slowly increase the GAIN knob until the signal indicator (if present) shows a healthy signal without clipping (red light).
- Adjusting Channel Volume: Use the LEVEL faders for Channels 1 & 2, and the dedicated volume knobs for 3/4 Channel/AUX, USB, and MP3/BT to balance the individual source volumes.
- Adjusting Main Output: Slowly increase the MAIN LEVEL knob to achieve the desired overall volume from your speakers.
- Headphone Monitoring: Adjust the Monitor Jack & Volume Knob for comfortable headphone listening.
6.2. Equalization (EQ)
Use the HIGH, MID, and LOW knobs on Channels 1 & 2 to shape the tone of your audio sources. Turning a knob clockwise boosts the frequency, while turning it counter-clockwise cuts it.
- HIGH: Affects treble frequencies (clarity, brightness).
- MID: Affects midrange frequencies (vocal presence, instrument body).
- LOW: Affects bass frequencies (warmth, thump).
6.3. Reverb Effect (FX)
The mixer includes a built-in reverb effect. Use the FX Reverb Effect Knobs on Channels 1 & 2 to add reverb to those channels. Turn the knob clockwise to increase the amount of reverb.
6.4. Phantom Power (+48V)
If you are using a condenser microphone with MIC/LINE 1, press the +48V Phantom Power Switch. This supplies the necessary power to the microphone. Caution: Do not activate phantom power for dynamic microphones or ribbon microphones unless specifically required by the microphone manufacturer, as it may cause damage.
6.5. Bluetooth Connectivity
- Press the MODE button in the Digital Audio Player section until "BT" appears on the display.
- On your smartphone or Bluetooth-enabled device, search for Bluetooth devices and select "BT-NSMIX".
- Once connected, you can play audio from your device through the mixer. Adjust the MP3/BT Volume Knob to control the volume.
- The maximum transmission distance for Bluetooth is approximately 35 feet (10 meters).
6.6. USB Audio Interface
Connect the mixer to your computer or smartphone using the USB to USB audio cable. The mixer will be recognized as an audio input/output device. You can use it for:
- Recording: All mixed audio from the mixer will be sent to your computer/smartphone for recording.
- Playback: Audio from your computer/smartphone can be played back through the mixer. Adjust the USB Level Knob for volume control.
Note: When using the USB audio interface for recording, all inputs are summed to a mono signal, and individual channels cannot be recorded separately.
7. Maintenance
7.1. Cleaning
Wipe the mixer and microphones with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish or internal components.
7.2. Microphone Battery Replacement
When the microphone display indicates low battery or the audio signal becomes weak/intermittent, replace the AA batteries. Always replace both batteries in a microphone at the same time with new ones.
7.3. Storage
Store the mixer and accessories in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove batteries from the wireless microphones.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to the mixer. | Power adapter not connected or faulty; outlet not working. | Check power cable connections. Try a different power outlet. Ensure the 5V 2A adapter is used. |
| No sound output from speakers. | MAIN OUT cables disconnected; MAIN LEVEL knob too low; speakers off or faulty. | Check MAIN OUT connections. Increase MAIN LEVEL. Ensure speakers are powered on and functioning. |
| No sound from a specific input channel. | Channel GAIN or LEVEL too low; input device not connected or faulty; incorrect input selected. | Increase GAIN and LEVEL for the channel. Check input cable connections. Ensure the input device is working. |
| Wireless microphones not working. | Microphones off; low batteries; interference; mixer's MIC ON A/B not selected. | Turn on microphones. Replace batteries. Try changing frequency (A/B) on the mixer. Ensure MIC ON A/B is active. |
| Bluetooth not connecting. | Mixer not in Bluetooth mode; incorrect device selected; device too far. | Press MODE button until "BT" is displayed. Ensure "BT-NSMIX" is selected on your device. Move device closer to the mixer. |
| Audio distortion or clipping. | GAIN or LEVEL set too high; input signal too strong. | Reduce GAIN and LEVEL knobs. If using MIC/LINE 1, activate the PAD switch. |
| Noticeable audio latency (delay). | Inherent to some digital audio processing; specific setup configurations. | While some latency is expected in certain setups, ensure all connections are direct and minimize unnecessary processing. For critical applications, consider dedicated low-latency interfaces. |
