Griffin PowerWave USB Audio Interface & Desktop Amplifier User Manual

Introduction

The Griffin PowerWave is a versatile USB audio interface and desktop amplifier designed for use with both Mac and PC computers. It allows users to record audio from microphones or line-level sources, convert analog audio collections (LPs, cassettes) to digital formats, and amplify audio for home speakers or portable devices like iPods and MP3 players. The PowerWave provides superior audio quality by isolating audio processing from the computer's internal electronic noise, delivering a cleaner sound experience.

Operating Instructions

1. Basic Audio Playback

Once connected, the PowerWave will appear as an available audio output device in your computer's sound settings. Select it as your default output to route all computer audio through the PowerWave and connected speakers.

2. Recording Audio

To record, select the PowerWave as your audio input device in your preferred recording software (e.g., Audacity, GarageBand, Adobe Audition). You can record from:

• Line Input: For converting LPs or cassette tapes to digital formats (CD or MP3).
• Mic Input: For recording microphones or musical instruments.

Adjust input levels within your software or using the PowerWave's controls (if available) to prevent clipping and ensure optimal recording quality.

3. Standalone Amplifier Use

The PowerWave can function as a compact standalone amplifier. Connect your iPod or MP3 player directly to the PowerWave's input, and connect passive speakers to its output. This allows you to amplify audio from portable devices without needing a computer connection.

Maintenance

The Griffin PowerWave requires minimal maintenance. Follow these guidelines to ensure longevity:

• Cleaning: Use a soft, dry cloth to wipe the exterior of the device. Avoid using liquid cleaners or abrasive materials, as they may damage the finish or internal components.
• Storage: Store the PowerWave in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Ventilation: Ensure the device has adequate ventilation and is not covered, to prevent overheating.

Troubleshooting

If you encounter issues with your PowerWave, refer to the following common solutions:

• No Sound Output:
  • Ensure the PowerWave is properly connected to power and your computer via USB.
  • Verify that the PowerWave is selected as the default audio output device in your computer's sound settings.
  • Check all speaker connections and ensure speakers are powered on (if applicable) and volume is turned up.
• Poor Audio Quality / Buzzing:
  • The PowerWave is designed to reduce noise from internal computer components. If you experience buzzing, ensure all cables are securely connected and try using a different USB port.
  • Avoid placing the PowerWave directly on top of other electronic devices that may cause interference.
• Loud Thump When Switching Gain: This is a known characteristic of the device when adjusting the gain switch. It does not indicate a malfunction.
• Blue Light Flashing: A flashing blue light indicates normal operation when the device is connected to a computer.
• Recording Issues:
  • Ensure the PowerWave is selected as the input device in your recording software.
  • Check input levels in your software to prevent distortion.
  • Verify that your audio source (microphone, LP player) is properly connected and functioning.
