- Uključivanje prijemnika: Connect the provided power adapter to the receiver's power input (220V-50Hz) and plug it into a suitable power outlet. Do not power on the receiver yet.
- Povežite se na audio sistem: Use the balanced XLR output or the mixed auxiliary (1/4" Jack) output on the receiver's rear panel to connect to your audio mixer, amplifier, or sound system.
- Install Batteries in Transmitters: Open the battery compartment on each bodypack transmitter and insert two AA batteries, observing the correct polarity (+/-). Close the compartment securely.
- Connect Microphones to Transmitters: Plug your chosen headset or lavalier microphone into the microphone input jack on each bodypack transmitter.
6. Uputstvo za upotrebu
- Uključeno: First, turn on your audio mixer/amplifier. Then, press the power switch on the receiver unit to turn it on. Finally, slide the ON/OFF/MUTE switch on each bodypack transmitter to the 'ON' position.
- Provjerite indikatore: Observe the RF (Radio Frequency) indicators on the receiver's front panel. They should illuminate, indicating that the receiver is receiving a signal from the transmitters.
- Podesite glasnoću: Speak into the microphones. The AF (Audio Frequency) indicators on the receiver should light up, indicating audio signal presence. Adjust the independent volume knobs for Channel A and Channel B on the receiver to achieve the desired output level.
- Using the Mute Function: To temporarily silence a microphone without turning off the transmitter, slide the ON/OFF/MUTE switch on the bodypack transmitter to the 'MUTE' position. Slide it back to 'ON' to resume audio transmission.
- Optimalni plasman: For headset microphones, position the boom mic approximately 2-3 cm from the corner of your mouth. For lavalier microphones, clip them to your clothing about 15-20 cm below your chin.
- Radni opseg: The system has an effective operating range of up to 80 meters in open, unobstructed environments. Walls, large metal objects, and other wireless devices may reduce this range.
- Iskljuciti: When finished, first slide the transmitter switches to 'OFF', then turn off the receiver, and finally turn off your audio mixer/amplifier.
7. Održavanje
- čišćenje: Use a soft, dry cloth to clean the receiver and transmitters. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.
- Zamjena baterije: Replace batteries in the bodypack transmitters when the audio quality degrades or the transmitter indicator light (if present) signals low battery. Always use fresh AA batteries.
- Skladištenje: When not in use for extended periods, remove batteries from the transmitters and store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
- Održavanje antene: Pažljivo rukujte antenama kako biste izbjegli savijanje ili lomljenje.
