- Avoid placing the amplifier in areas with poor ventilation.
3. Product Overview
The EDISION LIA-301 is an indoor antenna amplifier designed to enhance UHF/VHF signals for digital terrestrial TV. It features one RF input and three RF outputs, allowing connection to multiple televisions.
Key Features:
- UHF/VHF 20dB amplification.
- 1 RF input (UHF/VHF/FM) and 3 RF outputs (TV) with IEC connectors.
- Maximum output level of 98dBmV.
- Bandwidth: 47-694 MHz with integrated 5G LTE filter.
- Adjustable gain for UHF/VHF from 5 to 20dB.
- Ideal for situations where the signal at the TV outlet is weak.

4. Setup and Installation
Follow these steps to properly install your EDISION LIA-301 amplifier:
- Choose a Location: Install the amplifier indoors, close to your TV outlet and away from direct heat or moisture.
- Connect Antenna Input: Connect the coaxial cable from your antenna (or wall outlet) to the RF IN port on the amplifier. Ensure the connection is secure.
- Connect TV Outputs: Connect coaxial cables from the amplifier's TV output ports to the antenna input of your television(s). The LIA-301 provides three TV outputs.
- Power Connection: Plug the amplifier's power cable into a standard AC 100-240V, 50/60Hz wall outlet. A green LED indicator on the amplifier will illuminate, indicating power is supplied.
- Adjust Gain: Once connected and powered, you can adjust the gain using the dial on the amplifier (refer to Section 5: Operating Instructions for details).

5. Operating Instructions
The primary operation of the EDISION LIA-301 involves adjusting its gain to optimize signal reception.
- Power Indicator: The green LED on the amplifier indicates that the unit is powered on.
- Gain Adjustment: Locate the adjustable dial on the amplifier. This dial allows you to set the amplification level for UHF/VHF signals from 5dB to 20dB.
- Optimizing Signal:
- Start with the gain set to its minimum (5dB).
- Tune your TV to a channel that previously had a weak or pixelated signal.
- Slowly increase the gain by turning the dial clockwise until the picture quality improves and becomes stable.
- Avoid setting the gain too high, as this can lead to signal over-amplification, causing distortion or "intermodulation" (signal interference), which can worsen picture quality. If you experience this, slightly reduce the gain.
- 5G LTE Filter: The integrated 5G LTE filter automatically works to reduce interference from 5G mobile signals, ensuring a cleaner TV signal.
6. Maintenance
The EDISION LIA-301 amplifier requires minimal maintenance.
- Cleaning: Disconnect the amplifier from the power outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.
- Ventilation: Ensure that the ventilation slots on the amplifier are not blocked to prevent overheating.
- Cable Connections: Periodically check all coaxial cable connections to ensure they are secure and free from corrosion.
7. Troubleshooting
If you encounter issues with your EDISION LIA-301 amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power indicator light. | Amplifier not plugged in; power outlet faulty; power cable damaged. | Ensure the power cable is securely plugged into a working outlet. Check the power cable for damage. |
| No signal or poor picture quality after installation. | Incorrect cable connections; gain set too low; signal over-amplification; faulty cables. |
|
| Interference from mobile signals (e.g., 5G). | Strong local 5G/LTE signals. | The amplifier has an integrated 5G LTE filter. While it attenuates strong interfering signals, in extremely strong interference environments, some residual interference might occur. Ensure the gain is not set excessively high. |
