ROCKMIX 8: How To Connect A Laptop / Computer

Introduction

The Rockville Rock Mix 8 can be used as an audio interface to record audio directly onto your computer or playback sound through your mixer and connected speakers. This guide will walk you through connecting the Rock Mix 8 to your computer, configuring sound settings, recording in a DAW (Digital Audio Workstation), and troubleshooting common issues.

1. Connecting the Rock Mix 8 to a Computer

A. Using the USB Cable

1. Take the included USB-B to USB-A cable.
2. Plug the USB-B end into the Rock Mix 8.
3. Plug the USB-A end into your computer.
   • If using a newer laptop with only USB-C ports, use a USB-C to USB-A adapter.
4. Turn on the Rock Mix 8.

2. Configuring Computer Sound Settings

Before using the mixer, you need to configure your computer’s audio input and output settings.

A. Setting the Mixer as the Output Device (For Playback)

1. Open your computer’s Sound Settings.
2. Under Output Devices, select "USB Audio CODEC" as the default output.
3. This allows audio from your computer to be played through the mixer.

B. Setting the Mixer as the Input Device (For Recording)

1. In Sound Settings, go to Input Devices.
2. Select "USB Audio CODEC" as the default input.
3. This allows microphones and instruments connected to the mixer to be recorded into your computer.

C. Enabling USB Playback (To Hear Computer Audio Through the Mixer)

1. Press the USB Playback button on channels 5 and 6.
   • The button should be pushed in, and the USB Playback light will turn on.
2. Raise the level knob for channels 5 and 6.
3. Adjust the Main Mix knob to control overall volume.
4. Play audio from your computer to test the connection.

3. Recording with the Rock Mix 8 in a DAW

Once the mixer is connected, it can be used to record in any DAW (Digital Audio Workstation) such as GarageBand, FL Studio, Ableton Live, Pro Tools, Audacity, or Reaper.

A. Configuring the DAW for Recording

1. Open your DAW.
2. Navigate to the Audio Settings.
3. Under Input Device, select "USB Audio CODEC".
4. Under Output Device, select "USB Audio CODEC".

4. Recording Options: Stereo vs. Dual Mono

The Rock Mix 8 does not function as a multi-track interface, meaning all channels (1-6) are summed together into two recording inputs (1 and 2).

A. Stereo Recording (Captures All Mixer Audio as One Track)

1. Create a new stereo track in your DAW.
2. Select Input 1 & 2 as the recording source.
3. All audio coming from the mixer will be recorded into the DAW as a single stereo track.

B. Dual Mono Recording (Separate Left and Right Channels)

• To separate audio sources:
  • Pan Channel 1 fully left → Appears on Left input in DAW.
  • Pan Channel 2 fully right → Appears on Right input in DAW.
• This allows the vocals and an instrument (e.g., guitar) to be recorded separately but still within a single stereo track.

5. Recording Vocals and Instruments

A. Setting Up a Microphone for Recording

1. Plug a microphone into Channel 1 (XLR input).
2. If using a condenser microphone, press the phantom power button to activate +48V power.
3. Raise the Gain knob to adjust sensitivity.
4. Raise the Level knob to adjust volume.
5. Adjust EQ settings (High, Mid, Low) to fine-tune the sound.

B. Recording a Guitar Alongside a Microphone

1. Plug the guitar into Channel 2 (1/4” input).
2. Adjust the Gain and Level knobs for proper volume.
3. To separate vocals and guitar:
   • Pan Channel 1 (vocals) left.
   • Pan Channel 2 (guitar) right.
4. In your DAW, record using stereo mode (Input 1 & 2).
5. This will record vocals to the Left channel and guitar to the Right channel.

C. Using Headphones for Monitoring (Avoiding Speaker Feedback)

• When recording vocals:
  1. Lower speaker volume to avoid sound bleeding into the mic.
  2. Plug headphones into the Phones jack on the mixer.
  3. Use the Control Room knob to adjust headphone volume.

6. Playback and Mixing in Your DAW

A. Listening to Your Recording

1. Raise the speaker volume.
2. Ensure USB Playback is enabled on channels 5 & 6.
3. Play back the recorded track in your DAW.
4. Use the 3-band EQ and Balance knobs on the mixer to refine playback.

B. Adjusting Mix and Effects

• Apply effects like reverb, delay, and compression in your DAW.
• If using external effects processors, send the signal using the FX Send knob on each channel.

7. Troubleshooting & FAQs

Q: Why can’t I hear anything from my computer?

• Make sure USB Playback mode is engaged on channels 5 & 6.
• Confirm that your computer’s Output Device is set to USB Audio CODEC.
• Raise the level knobs for channels 5 & 6 and the Main Mix knob.

Q: My DAW is not detecting the mixer as an input device.

• Ensure USB Audio CODEC is selected as the Input Device in DAW settings.
• Restart your computer and DAW.
• Try using a different USB port or cable.

Q: Can I record multiple tracks separately in my DAW?

• No, the Rock Mix 8 functions as a stereo USB interface.
• You can record in Stereo (Input 1 & 2 combined) or Dual Mono (Left & Right panned separately).

Q: Why is my microphone picking up speaker noise?

• Reduce speaker volume when recording.
• Use headphones for monitoring.
