2. Plug the power adapter into a suitable electrical outlet.

4.3 Audio Output Connection

Connect the receiver to your mixer, amplifier, or sound system using one of the following methods:

• Individual XLR Outputs: For separate control over each microphone channel, connect XLR cables (not included) from the A, B, C, and D XLR outputs on the receiver to the corresponding input channels on your mixer.
• Mixed 1/4" Output: For a combined output of all microphone channels, use the provided 1/4" audio cable to connect the 6.35mm MIX output on the receiver to a 1/4" input on your mixer or amplifier.

4.4 Microphone Battery Installation

Each handheld microphone and bodypack transmitter requires batteries for operation. The specific battery type is typically AA. Please refer to the microphone's compartment for exact battery requirements.

1. Unscrew the bottom cap of the handheld microphone or open the battery compartment of the bodypack transmitter.
2. Insert the required batteries, ensuring correct polarity (+/-).
3. Securely close the battery compartment or screw the cap back on.

5. Operating Instructions

5.1 Powering On/Off

1. Receiver: Press the power button on the front panel of the receiver. The display should illuminate.
2. Microphones: Turn on each handheld microphone or bodypack transmitter using its respective power switch.

5.2 IR Synchronization

The system uses IR synchronization to pair the microphones with the receiver channels.

1. Ensure both the receiver and the desired microphone are powered on.
2. On the receiver, select the channel you wish to pair.
3. Activate the IR sync function on the receiver (refer to the receiver's front panel controls for the specific button).
4. Align the IR window on the microphone (usually near the display or battery compartment) with the IR sensor on the receiver (typically on the front panel).
5. The receiver and microphone will synchronize automatically within seconds. The microphone's display should show the same frequency as the receiver channel.

5.3 Frequency Selection (Auto Scan)

The auto-scan feature helps find the clearest available frequency to avoid interference.

1. On the receiver, select the channel for which you want to change the frequency.
2. Press the 'Auto Scan' button (or similar) on the receiver. The receiver will search for an interference-free frequency.
3. Once a new frequency is found, perform IR synchronization (as described in Section 5.2) to pair the microphone with the new frequency.

5.4 Volume Adjustment

Each channel on the receiver typically has an individual volume control knob on the front panel. Adjust these knobs to set the desired output level for each microphone. Further volume adjustments can be made on your connected mixer or amplifier.
