3. Setup Instructions

3.1 Receiver Setup

Connect Antennas: Screw the four included antennas into the ANT.1, ANT.2, ANT.3, and ANT.4 ports on the rear of the receiver. Ensure they are securely tightened.
Power Connection: Connect the power cable to the DC 12-15V input on the receiver and plug it into a suitable power outlet.
Audio Output: Connect the receiver to your mixer, amplifier, or PA system using the 6.35mm audio cable for mixed output, or individual XLR cables for balanced output from each channel.
Power On: Press the power switch on the front panel of the receiver to turn it on. The display will illuminate.

3.2 Transmitter Setup (Handheld/Bodypack)

Battery Installation: Open the battery compartment of the handheld microphone or bodypack transmitter. Insert two AA batteries, ensuring correct polarity.
Power On: Press and hold the power button on the transmitter until the display illuminates.
Frequency Pairing: The system features automatic frequency technology. To pair a transmitter with a receiver channel, ensure both are powered on. Press the 'SET' button on the transmitter to initiate pairing. The receiver channel display should show a successful connection. If needed, use the 'VOL+' or 'VOL-' buttons on the transmitter to select a different frequency option (each mic has 5 options).
Microphone Connection (Bodypack): If using a bodypack transmitter, connect the headset or lavalier microphone to the input jack on the bodypack.

4. Operating Instructions

4.1 Power On/Off

To power on the receiver, press the 'POWER' button on the front panel.
To power on a transmitter, press and hold its power button until the display activates.
To power off, reverse the process.

4.2 Volume Control

Each channel on the receiver has an independent volume knob (VOL.1 to VOL.8) to adjust the output level for that specific microphone.
Transmitters also have 'VOL+' and 'VOL-' buttons for fine-tuning the input sensitivity.

4.3 Channel and Frequency Adjustment

The receiver's display shows the active channel and frequency for each microphone.
If interference occurs, you can change the frequency of a transmitter. Press the 'SET' button on the transmitter to enter frequency selection mode, then use 'VOL+' or 'VOL-' to cycle through the 5 available frequency options for that microphone. Press 'SET' again to confirm.

4.4 Optimal Operating Range

The system provides a reliable wireless signal range of up to 50 meters (160 feet) under ideal conditions. Ensure a clear line of sight between the transmitters and the receiver antennas for best performance.

6. Troubleshooting

Problem	Possible Cause	Solution
No sound from microphone	Microphone/receiver not powered on Low or dead batteries in transmitter Incorrect frequency pairing Audio cable disconnected Receiver volume too low	Ensure all components are powered on. Replace batteries in the transmitter. Re-pair the transmitter and receiver channel. Check all audio cable connections. Increase receiver channel volume and master volume on your mixer/amplifier.
Interference or static noise	Other wireless devices operating on similar frequencies Obstructions between transmitter and receiver Weak signal due to distance	Change the frequency of the affected microphone. Ensure clear line of sight between transmitter and receiver antennas. Reduce the distance between the transmitter and receiver. Avoid placing the receiver near sources of electromagnetic interference.
Short operating range	Antennas not properly connected or positioned Environmental obstructions Low transmitter power (due to batteries)	Ensure antennas are securely connected and oriented vertically. Minimize obstructions between transmitter and receiver. Replace transmitter batteries.
