3. Setup Instructions

The PROZOR 4-Channel Stereo Audio Mixer is a plug-and-play device that does not require external power. Follow these steps to set up your mixer:

1. Identify Inputs and Outputs: Locate the four stereo RCA input pairs (IN1, IN2, IN3, IN4) and the single stereo RCA output pair (OUT) on the mixer.
2. Connect Audio Sources: Connect your audio source devices (e.g., TV, PC, CD player, instrument) to the desired input channels (IN1-IN4) using stereo RCA cables. Ensure left (white) and right (red) channels are correctly matched.
3. Connect Audio Output: Connect the mixer's OUT port to your audio receiving device (e.g., amplifier, soundbar, powered speakers) using a stereo RCA cable.
4. Initial Volume Settings: Before playing audio, set all independent volume control knobs on the mixer to their minimum position (fully counter-clockwise).

4. Operating Instructions

Once connected, operate the mixer using the independent volume controls:

1. Power On Devices: Turn on all connected audio source devices and your audio receiving device.
2. Adjust Master Volume: Set the volume on your audio receiving device (amplifier, soundbar, etc.) to a moderate listening level.
3. Control Input Volumes: Gradually turn the volume knob for each active input channel on the mixer clockwise to increase its level. Adjust each channel independently to achieve the desired mix and balance between your audio sources.
4. Passive Operation Note: As a passive device, this mixer does not amplify the audio signal. It can only attenuate (reduce) the signal. If your audio sources have very low output levels, you may experience a lower overall volume. In such cases, an external pre-amplifier might be necessary before the mixer or a powerful amplifier after it.

5. Maintenance

To ensure the longevity and optimal performance of your PROZOR 4-Channel Stereo Audio Mixer, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the mixer. Avoid using liquid cleaners, solvents, or abrasive materials, as these can damage the finish or internal components.
• Connector Care: Periodically inspect the RCA connectors for dust or debris. Use a small, soft brush or compressed air to clean them if necessary. Avoid bending or forcing connections.
• Storage: When not in use for extended periods, store the mixer in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: While the metal housing is durable, avoid dropping the unit or subjecting it to strong impacts, which could damage internal circuitry or connectors.

6. Troubleshooting

If you encounter issues with your mixer, refer to the following troubleshooting steps:

• No Sound Output:
  • Ensure all RCA cables are securely connected to both the mixer and the audio source/receiving devices.
  • Verify that all connected audio sources are powered on and playing audio.
  • Check that the volume knobs on the mixer for the active channels are turned up.
  • Confirm that the volume on your audio receiving device (amplifier, soundbar) is adequately set.
• Distorted or Unclear Sound:
  • Ensure that the audio source levels are not excessively high, which could cause clipping or distortion. Adjust the source device's volume if possible.
  • Check for damaged or faulty RCA cables. Try swapping cables to isolate the issue.
  • Verify that the mixer's volume knobs are not set too high, especially if the input signal is already strong.
• Unbalanced Audio Levels Between Channels:
  • Use the independent volume control knobs for each channel to balance the audio levels as desired.
  • Note that different audio sources may have varying output levels. Adjust accordingly.
• Low Overall Volume:
  • Remember that this is a passive mixer and does not provide amplification. If your audio sources have very low output levels, the combined signal may also be low.
  • Consider using a pre-amplifier for your low-level audio sources before connecting them to the mixer, or ensure your receiving amplifier has sufficient gain.
