5. Setup

5.1 Physical Placement

For optimal bass performance, consider placing the subwoofer in a corner of the room or along a wall. Experiment with different positions to find the best sound balance for your listening environment. Ensure there is adequate space for ventilation.

5.2 Connections

The Edifier T5s offers versatile connectivity options to integrate with various audio systems.

Method 1: If Your Speaker System Has a Sub-Out Port

This method is ideal for speaker systems equipped with a dedicated subwoofer output.

1. Connect the RCA cable from your speaker system's 'Sub-Out' or 'LFE Out' port to the 'Signal In' (RCA) ports on the Edifier T5s subwoofer.
2. Ensure the power cable is securely connected to the subwoofer and a power outlet.

Method 2: If Your Speaker System Does Not Have a Sub-Out Port

This method allows you to integrate the T5s with speaker systems that lack a dedicated subwoofer output, such as many desktop or bookshelf speakers.

1. Connect the audio source (e.g., TV, PC, CD player) to the 'Signal In' (RCA) ports on the Edifier T5s subwoofer using the provided RCA cables.
2. Connect your main speaker system's input to the 'Signal Out' (RCA) ports on the Edifier T5s subwoofer. This allows the subwoofer to pass the full-range audio signal to your main speakers after processing the low frequencies.
3. Ensure the power cable is securely connected to the subwoofer and a power outlet.

6. Operating

6.1 Controls

The Edifier T5s features controls on the rear panel for fine-tuning its performance to your listening preferences and room acoustics:

• Volume Control: Adjusts the overall output level of the subwoofer. Start with a low setting and gradually increase until the bass blends seamlessly with your main speakers.
• Low-Pass Filter (Crossover Frequency): This knob allows you to set the upper frequency limit for the subwoofer, typically ranging from 30Hz to 160Hz. Frequencies above this setting will be rolled off. Adjust this to match the low-frequency capabilities of your main speakers. A common starting point is around 80Hz-100Hz.
• Phase Selector (0°/180°): This switch helps to ensure that the subwoofer's sound waves are in sync with your main speakers. If the bass sounds weak or hollow, try flipping this switch to the opposite setting. Listen for the setting that provides the most impactful and cohesive bass.

6.2 Auto-Standby Function

The T5s is equipped with an energy-efficient auto-standby feature. If no audio signal is detected for approximately 15 minutes, the subwoofer will automatically enter a low-power sleep mode (0.5W). It will instantly wake up and resume operation as soon as an audio signal is detected.

7. Maintenance

Proper maintenance will help ensure the longevity and performance of your Edifier T5s Subwoofer.

• Cleaning: Use a soft, dry cloth to clean the surface of the subwoofer. Do not use liquid cleaners, aerosols, or abrasive chemicals, as they may damage the finish.
• Dust: Regularly dust the unit, especially around the port and connections, to prevent dust buildup.
• Environment: Avoid placing the subwoofer in direct sunlight, near heat sources, or in areas with high humidity or extreme temperatures.
• Handling: Handle the subwoofer with care. Avoid dropping or subjecting it to strong impacts.

8. Troubleshooting

If you encounter any issues with your Edifier T5s Subwoofer, please refer to the following common problems and solutions:

• No Sound:
  • Ensure the power cable is securely connected and the power outlet is active.
  • Check all audio cables are correctly connected to both the subwoofer and your audio source/main speakers.
  • Verify the volume control on the subwoofer is not set to minimum.
  • Check the volume level of your audio source.
• Weak or Distorted Bass:
  • Adjust the volume control on the subwoofer.
  • Experiment with the Phase Selector (0°/180°) to find the optimal setting for your room and main speakers.
  • Adjust the Low-Pass Filter (Crossover Frequency) to ensure it blends well with your main speakers.
  • Check for proper placement; sometimes moving the subwoofer a small distance can significantly improve bass response.
  • Ensure the audio source is providing a clean signal.
• Subwoofer Not Entering/Exiting Standby:
  • The auto-standby feature requires a certain level of audio signal to detect activity. Ensure your audio source is playing at a sufficient volume.
  • If the subwoofer does not wake up, try turning it off and on again using the power switch.
• Humming or Buzzing Noise:
  • Ensure all cables are securely connected.
  • Try plugging the subwoofer into a different electrical outlet.
  • Check if the noise persists when the audio cables are disconnected from the subwoofer. If it stops, the noise might be coming from the audio source or cables.
