What's Included

• Rock Mix 8 mixer
• USB cable (for computer connection or power)
• USB power block (for powering through an outlet)
• Optional DC to USB power cable

Step-by-Step Setup

1. Powering the Mixer

• Plug the USB cable into the mixer.
• Connect the other end to the USB power block.
• Plug the power block into an outlet.

Alternative Power Option: Use the DC to USB cable for portable power.

2. Connecting the Mixer to Speakers

• Use two 1/4” mono cables to connect speakers to the Main Outputs or Control Room Outputs.
• Main Outputs: For main PA speakers or studio monitors.
• Control Room Outputs: For an alternate mix, like monitor speakers.
• Turn on the mixer first, then the speakers (to avoid popping sounds).
• Adjust the volume knobs on your speakers.

Using the Mixer

3. Understanding Gain vs. Level Knobs

• Gain Knob: Controls the sensitivity of the microphone or instrument input.
• Level Knob: Adjusts the volume of the channel in the mix.
• Monitor the Peak LED lights to prevent clipping or distortion.

4. Connecting Microphones & Instruments

Connecting a Dynamic or Condenser Microphone

• Use an XLR cable to connect the microphone to Channel 1 or 2.
• For condenser microphones, enable phantom power (48V button).
• Raise the Gain knob and then adjust the Level knob.
• Monitor Peak LED lights to prevent distortion.

Connecting a Guitar, Bass, or Keyboard

• Use a 1/4” instrument cable.
• Plug into Channel 1 or 2 (for mono) or Channels 3/4, 5/6 for stereo).
• Raise the Gain and Level knobs to adjust the signal.

Adjusting Sound & Effects

5. Compressor (Channels 1 & 2 Only)

• The one-knob compressor reduces loud peaks and enhances vocal and instrument clarity.
• Turning the compressor knob up will make quiet sounds louder and loud sounds softer for a balanced signal.

6. 3-Band EQ (Channels 1-6)

• High (Treble): Adds clarity and brightness.
• Mid: Adjusts vocal presence and instrument body.
• Low (Bass): Controls deep bass frequencies.

7. FX Send & External Effects Processing

• The FX knob sends audio to an external effects processor (e.g., reverb, delay).
• Connect a 1/4” cable from the FX Send to an effects processor.
• Route the processed signal back into the Aux In or another channel.

8. Using the Mixer for Monitor Speakers

• Use the FX Send output for a monitor speaker feed.
• Adjust the FX knob on each channel to send sound to the monitor.

Bluetooth & USB Playback

9. Connecting via Bluetooth

• Press the Bluetooth button on the mixer.
• On your smartphone or tablet, enable Bluetooth and search for "Rock Mix 8".
• Tap to connect (a sound confirms pairing).
• Play music through Channels 3/4 and adjust EQ settings.

10. USB Playback from a Computer

• Press the USB Playback button to monitor USB audio.
• Adjust Channels 5/6 to control USB playback volume.
• Works with YouTube, Spotify, and DAWs (Digital Audio Workstations).

Recording with a Computer

11. Setting Up the Mixer as an Audio Interface

• Connect the USB cable from the mixer to your computer.
• Go to your computer’s sound settings and select "USB Audio Codec" as both input and output.
• Open your DAW (e.g., GarageBand, Audacity, Pro Tools, etc.).
• Set the audio input and output to USB Audio Codec.
• Enable monitoring in your DAW to hear the mix.

12. Recording Tracks in a DAW

• The Rock Mix 8 records a stereo mix, not individual channels.
• For dual-track recording:
  • Pan Channel 1 (Vocals) Left → Assigned to Track 1 in DAW.
  • Pan Channel 2 (Guitar) Right → Assigned to Track 2 in DAW.

13. Using Headphones & Control Room Monitors

• Plug headphones into the headphone jack.
• Adjust the Headphone/Control Room volume knob.
• If using control room speakers, plug them into the Control Room Outputs.

Troubleshooting

No Sound from Speakers?

• Check that Main Mix and Level knobs are raised.
• Ensure the speakers are powered and connected.
• Confirm that the correct outputs (Main or Control Room) are used.

Microphone Not Working?

• Make sure phantom power is on for condenser mics.
• Adjust the Gain knob and Level knob.
• Test with a different XLR cable or microphone.

Distorted Audio or Clipping?

• Lower the Gain or Level knob on the channel.
• Check if Peak LED lights are flashing—this indicates the signal is too loud.

USB Not Recognized by Computer?

• Unplug the USB cable, wait 30 seconds, and reconnect.
• Restart the computer and try again.
• Ensure USB Audio Codec is selected as the input/output.
