5. Setup
5.1 Power Connection
- Ensure the mixer's power switch is in the OFF position.
- Connect the provided power adapter to the mixer's power input port on the rear panel.
- Plug the power adapter into a standard AC 110V 50Hz electrical outlet.
- Turn the mixer's power switch ON. The POWER indicator will illuminate.
5.2 Input Connections
The mixer features 8 mono input channels, each with an XLR microphone input and a 1/4" TRS line input.
- Microphones: Connect microphones to the XLR inputs (labeled 'MIC'). For condenser microphones requiring phantom power, activate the +48V switch located in the master section. Ensure all microphone gains are set to minimum before engaging phantom power.
- Line-Level Devices: Connect instruments or other line-level audio sources (e.g., keyboards, drum machines) to the 1/4" TRS 'LINE' inputs.
5.3 Output Connections
- Main Output: Connect the 'L MAIN R' XLR outputs to your amplifier or powered speakers. Remember, an amplifier is required.
- Headphones: Plug headphones into the 'PHONES' 1/4" TRS jack. Adjust headphone volume using the dedicated 'HEADPHONES' knob.
- AUX Send/Return: Use the 'AUX SEND' and 'RETURN' jacks for connecting external effects processors or monitor systems.
- 2-Track Send/Return: The RCA 'TAPE IN' and 'TAPE OUT' jacks allow connection to recording devices or playback sources.

6. Operating Instructions
6.1 Channel Controls (Channels 1-8)
Figure 5: Close-up of individual channel controls, including GAIN, 3-band EQ (HF, MF, LF), AUX, FX, PAN, and channel faders.
- GAIN: Adjusts the input sensitivity for each channel. Start with the knob fully counter-clockwise and gradually increase until the signal is strong without clipping (indicated by the PFL/CLIP LED).
- EQ (HF, MF, LF): Three-band equalizer for shaping the tone of each channel. HF (High Frequency), MF (Mid Frequency), and LF (Low Frequency) knobs allow boosting or cutting specific frequency ranges.
- AUX: Controls the amount of signal sent to the auxiliary output, typically used for monitor mixes.
- FX: Controls the amount of signal sent to the internal effects processor.
- PAN: Adjusts the stereo position of the channel's signal (left to right).
- PFL (Pre-Fader Listen): Activates pre-fader listening for the channel, allowing monitoring through headphones without affecting the main mix.
- Channel Fader: Controls the volume level of the individual channel in the main mix.
6.2 Master Section Controls

- USB/MP3 Player:
- USB Port: Insert a USB flash drive with MP3 files.
- Display: Shows track information and mode.
- Controls: Use the buttons (MENU, PLAY/PAUSE, SKIP TRACKS) to navigate and control playback.
- Mode Switch: Toggle between USB, Bluetooth, and other input modes.
- Bluetooth Connectivity:
- Switch the USB/MP3 player to Bluetooth mode.
- On your mobile device, search for available Bluetooth devices and select the mixer (usually named 'BT-AUDIO' or similar).
- Once paired, audio from your device will play through the mixer.

- Effects (FX):
- FX Knob: Controls the overall level of the internal effects.
- DLY (Delay): Adjusts the delay time of the effect.
- REP (Repeat): Adjusts the number of repetitions for the delay effect.
- AUX MST: Master level control for the auxiliary send.
- TAPE INPUT: Volume control for the RCA 'TAPE IN' input.
- HEADPHONES: Volume control for the headphone output.

- Main Faders (L MAIN R): Controls the overall output volume of the stereo main mix.
- Level Meters: LED indicators display the output level of the main mix, ranging from -24dB to CLIP. Adjust main faders to keep levels below CLIP to avoid distortion.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the mixer's surface. Avoid liquid cleaners or abrasive materials.
- Storage: Store the mixer in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Management: Ensure cables are not kinked or strained to prevent damage to connectors and internal wiring.
- Ventilation: Do not block the ventilation slots on the mixer to ensure proper heat dissipation.
8. Troubleshooting
- No Sound Output:
- Check if the mixer is powered on and connected to an amplifier.
- Ensure main faders and channel faders are raised.
- Verify all cables are securely connected.
- Check if the correct input source is selected (e.g., USB, Bluetooth).
- Distorted Sound:
- Reduce input GAIN levels on individual channels.
- Lower the main faders if the CLIP indicator is frequently lighting up.
- Check the amplifier's input level.
- Bluetooth Connection Issues:
- Ensure the mixer is in Bluetooth mode.
- Move the Bluetooth device closer to the mixer.
- Try unpairing and re-pairing the device.
- Excessive Noise:
- Ensure all unused inputs are muted or have their gain turned down.
- Check for ground loops or faulty cables.
- Verify that the mixer is connected to a properly grounded power outlet.
