Control Panel Description:

• MIC/LINE Inputs (Channels 1-2, 3/4, 5/6): Combo XLR/TRS jacks for connecting microphones or line-level instruments. Channels 1 and 2 are mono, while 3/4 and 5/6 can be used as stereo pairs or mono inputs.
• LO CUT 75Hz Switch: Activates a low-cut filter at 75 Hz for the respective input channel, useful for removing unwanted low-frequency rumble from microphones.
• LOW Knob: Adjusts the low-frequency equalization for the channel.
• FX Knob: Controls the amount of signal sent from the channel to the internal effects processor.
• MIX Knob (Channels): Adjusts the individual channel's volume level in the main mix.
• 24-BIT DIGITAL EFFECT Section: Contains controls for the built-in digital effects processor.
• PRESET Knob: Selects one of the 16 available digital effect presets. The LED display shows the selected preset number.
• FX LEVEL Knob: Adjusts the overall output level of the effects processor.
• FX Button: Engages or disengages the effects processor.
• PEAK LED: Illuminates when the effects processor input signal is too high, indicating potential clipping.
• PHANTOM POWER Switch: Activates +48V phantom power for condenser microphones connected to the XLR inputs.
• ON LED: Indicates that the mixer is powered on.
• CLIP LED: Illuminates when the main output signal is too high, indicating clipping.
• Level Meter LEDs (-20, -10, 0, +6): Provide visual indication of the main output signal level.
• MAIN MIX Outputs (L/R): XLR outputs for connecting the main stereo mix to an amplifier or recording device.
• PHONES Output: TRS jack for connecting headphones for monitoring.
• MIX Knob (Master): Controls the overall volume level of the main stereo mix.

3. Setup

3.1 Power Connection

1. Ensure the mixer's power switch is in the OFF position.
2. Connect the provided power adapter to the mixer's power input.
3. Plug the power adapter into a suitable AC power outlet.

3.2 Audio Input Connections

• Microphones: Connect microphones to the MIC/LINE XLR inputs (Channels 1-2, 3/4, 5/6). If using condenser microphones, ensure the PHANTOM POWER switch is engaged.
• Line-Level Instruments: Connect instruments such as keyboards, guitars with preamps, or media players to the MIC/LINE TRS inputs. For stereo sources, use channels 3/4 or 5/6.

3.3 Audio Output Connections

• Main Output: Connect the MAIN MIX XLR outputs (L/R) to your amplifier, powered speakers, or recording interface.
• Headphones: Connect your headphones to the PHONES TRS output for monitoring.

4. Operating Instructions

4.1 Powering On/Off

1. Before powering on, ensure all channel MIX knobs and the master MIX knob are set to their minimum position (-∞).
2. Flip the power switch to the ON position. The ON LED will illuminate.
3. To power off, first lower all volume levels, then flip the power switch to OFF.

4.2 Adjusting Input Levels

1. For each active input channel, gradually increase its MIX knob.
2. Monitor the main output level meters. Adjust individual channel MIX knobs to achieve a healthy signal level without the CLIP LED illuminating.
3. If using microphones, consider engaging the LO CUT 75Hz switch to reduce low-frequency noise.

4.3 Using the Equalizer (EQ)

Each channel features a LOW knob to adjust the low-frequency content of the input signal. Rotate clockwise to boost low frequencies or counter-clockwise to cut them.

4.4 Applying Digital Effects

1. Press the FX button to engage the effects processor.
2. Use the PRESET knob to select one of the 16 available effects. The LED display will show the preset number. Refer to the mixer's panel for a list of effects (e.g., Hall, Room, Vocal, Plate, Delay, Chorus).
3. Adjust the FX knob on individual channels to send the desired amount of signal to the effects processor.
4. Use the master FX LEVEL knob to control the overall volume of the applied effect in the main mix.
5. If the PEAK LED illuminates, reduce the FX knob on individual channels or the master FX LEVEL.

4.5 Phantom Power

The PHANTOM POWER switch provides +48V DC to the XLR inputs, necessary for operating condenser microphones. Only engage this switch when condenser microphones are connected. Ensure all channel volumes are down before engaging or disengaging phantom power to prevent loud pops.

4.6 Monitoring

Connect headphones to the PHONES output to monitor the main mix. The headphone volume is typically controlled by the master MIX knob.

5. Maintenance

5.1 Cleaning

Clean the mixer's exterior with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents. Avoid spraying liquids directly onto the unit.

5.2 Storage

When not in use for extended periods, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. Disconnect the power adapter.

6. Troubleshooting

• No Sound Output:
  • Check all power connections and ensure the mixer is ON.
  • Verify that all channel MIX knobs and the master MIX knob are turned up.
  • Ensure input sources are connected correctly and producing a signal.
  • Check connections to your amplifier/powered speakers.
• Distorted Sound:
  • Reduce individual channel MIX knobs or the master MIX knob if the CLIP LED is illuminated.
  • Check input levels from your sources to ensure they are not overdriving the mixer's inputs.
• Effects Not Working:
  • Ensure the FX button is engaged.
  • Check that the FX knob on the desired channel is turned up.
  • Verify the master FX LEVEL knob is turned up.
• No Phantom Power:
  • Ensure the PHANTOM POWER switch is engaged.
  • Confirm that the microphone requires phantom power.
