5. Istruzioni per l'installazione
5.1 Configurazione del ricevitore
- Posizionamento: Place the receiver on a stable, flat surface, away from potential sources of interference (e.g., computers, Wi-Fi routers). Ensure adequate ventilation around the unit.
- Connessione dell'antenna: Screw the four included antennas onto the ANT A, ANT B, ANT C, and ANT D connectors on the rear panel of the receiver. Position them vertically for optimal signal reception.
- Collegamento elettrico: Connect the supplied power adapter to the DC 16V, 400mA input on the rear of the receiver, then plug it into a suitable power outlet.
- Uscita audio: Collega il ricevitore al tuo mixer, amplifier, or sound system using either the 6.3cm (1/4 inch) mixed output or the individual 6.3cm (1/4 inch) outputs for each channel (OUT A, OUT B, OUT C, OUT D).


5.2 Impostazione del trasmettitore
- Installazione della batteria: Open the battery compartment of each bodypack transmitter. Insert two 1.5V AA batteries, ensuring correct polarity. Close the compartment securely.
- Connessione microfono: Plug the lavalier or headset microphone into the input jack on the bodypack transmitter.
- Accensione: Turn on the power switch on the bodypack transmitter. The LCD display will illuminate, showing the channel and battery status.
6. Istruzioni per l'uso
- Accensione del sistema: First, power on the receiver. Then, power on each bodypack transmitter.
- Regolazione del volume: Use the individual volume control knobs on the receiver for each channel (CH 01, CH 02, CH 03, CH 04) to adjust the microphone levels. Start with the volume low and gradually increase it to avoid feedback.
- Indicatori di segnale: The receiver's LCD display will show the active channel frequencies. The RF (Radio Frequency) and AF (Audio Frequency) indicators will light up when a signal is being received and audio is present, respectively.
- Utilizzo: Position the lavalier microphone approximately 6-8 inches from your mouth, or wear the headset microphone comfortably. Speak clearly into the microphone.
- Spegnimento: When finished, first turn off the bodypack transmitters, then power off the receiver. This helps prevent pops or thumps through your sound system.
7. Manutenzione
- Pulizia: Use a soft, dry cloth to clean the receiver and transmitters. Do not use liquid cleaners or solvents.
- Sostituzione della batteria: Replace batteries in the bodypack transmitters when the low battery indicator appears on the LCD display. Always use fresh, high-quality 1.5V AA batteries.
- Magazzinaggio: Store the system in a cool, dry place when not in use. Remove batteries from transmitters if storing for extended periods to prevent leakage.
- Cura dell'antenna: Handle antennas carefully. Avoid bending them excessively.
