4. Configuración
4.1 Montaxe
The Wisi VX 81 0S amplifier is designed for wall mounting. Use appropriate screws and anchors suitable for your wall material to securely fasten the device. Ensure sufficient space around the amplifier for ventilation and cable connections.
4.2 Conexións por cable
- Connect the incoming signal cable from your antenna or cable provider to the 'Input DS' porto no ampmáis vivo.
- Connect the outgoing signal cable(s) to your distribution network or individual devices from the 'Output DS' porto.
- Ensure all F-connectors are securely tightened to prevent signal loss.
4.3 Conexión de alimentación

5. Instrucións de funcionamento
The Wisi VX 81 0S features a variable damping regulator, which is a rotary selector, allowing you to adjust the signal amplification level. This adjustment helps optimize signal quality and prevent over-amplification or under-amplificación.
5.1 Adjusting Signal Level
- Locate the rotary selector on the ampmáis vivo.
- Slowly turn the selector clockwise to increase amplification or counter-clockwise to decrease it.
- Monitor the signal quality on your connected television or other receiving devices while making adjustments. Aim for a clear, stable picture and sound without distortion.
- Optimal adjustment ensures that the signal is strong enough to overcome cable losses but not so strong that it overloads the receiving equipment.
6. Mantemento
- Limpeza: Use un pano suave e seco para limpar o exterior ampNon empregue produtos de limpeza líquidos nin materiais abrasivos.
- Ventilación: Periodically check that the ventilation slots are free from dust and debris to ensure proper heat dissipation.
- Conexións por cable: Occasionally inspect all cable connections for tightness and signs of corrosion. Re-tighten if necessary.
- Condicións ambientais: Asegurar o amplifier remains in a dry, indoor environment within its specified operating temperature range.
7 Solución de problemas
7.1 No Signal or Weak Signal
- Comprobar a potencia: Asegurar o amplifier is properly plugged in and receiving power.
- Conexións por cable: Verify that all input and output cables are securely connected to the amplifier and receiving devices.
- Fonte do sinal: Confirm that the incoming signal from your antenna or cable provider is active and strong enough.
- Axustar Amplificación: Use the rotary selector to adjust the amplification level. Too low or too high amplification can cause signal issues.
- Bypass Test: Temporarily bypass the amplifier by connecting the input cable directly to a receiving device to determine if the issue lies with the amplifier ou a fonte de sinal.
7.2 Distorted Picture or Sound
- sobre-amplificación: Reducir o amplification level using the rotary selector. An excessively strong signal can cause distortion.
- Calidade do cable: Ensure you are using high-quality coaxial cables. Damaged or low-quality cables can introduce noise.
- Interferencia: Comprobe se hai dispositivos electrónicos próximos que poidan estar a causar interferencias.
