3. Setup

3.1 Receiver Connections

1. Power Input: Connect the provided DC 12V power adapter to the 'DC 12V' input on the rear panel of the receiver and plug it into a power outlet.
2. Antenna Installation: Screw the receiver antennas into the 'ANT 1+2' and 'ANT 3+4' (or similar, depending on model) interfaces on the rear panel. Ensure they are securely tightened and positioned for optimal signal reception.
3. Audio Output: Connect the receiver to your audio mixer or amplifier using either the individual XLR outputs for each channel (BALANCED 1-8) or the combined 6.35mm Mix Out (UNBALANCED) port.

3.2 Bodypack Transmitter Setup

1. Battery Installation: Open the battery compartment of each bodypack transmitter. Insert two AA batteries, ensuring correct polarity. The system does not have a built-in battery, so user-supplied batteries are required.
2. Headset Microphone Connection: Plug the headset microphone into the input jack on the bodypack transmitter.
3. Power On: Press and hold the power button on the bodypack transmitter to turn it on.

3.3 Channel Synchronization (IR Sync)

The K26R Pro system uses IR (Infrared) synchronization to pair transmitters with receiver channels. Follow these general steps:

1. Ensure both the receiver and the desired bodypack transmitter 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 display and controls for specific instructions, usually involving a 'SET' button or similar).
4. Align the IR window of the bodypack transmitter with the IR sensor on the receiver.
5. The receiver will transmit the frequency information to the bodypack, and the bodypack's display will show the synchronized channel and frequency.
6. Repeat for all 8 bodypack transmitters.

4. Operating Instructions

4.1 Power On/Off

• Receiver: Use the central 'POWER' button on the front panel to turn the receiver ON or OFF.
• Bodypack Transmitters: Press and hold the power button on each bodypack to turn it ON or OFF.

4.2 Volume Adjustment

• Bodypack Transmitters: Use the 'VOL+' and 'VOL-' buttons on the bodypack to adjust the input sensitivity or output volume of the transmitter.
• Receiver: Each channel on the receiver has a dedicated volume knob to control the output level of that specific microphone.

4.3 Channel Selection and Frequency Adjustment

The receiver's display shows the information content for each channel, including frequency. If manual frequency adjustment or channel scanning is needed, use the 'SET' button and channel function buttons on the receiver's front panel. Refer to the receiver's display for current channel and frequency information.

5. Maintenance

• Battery Replacement: Regularly check the battery level indicators on the bodypack transmitters. Replace AA batteries when low to ensure uninterrupted performance.
• Cleaning: Use a soft, dry cloth to clean the receiver and bodypack transmitters. Avoid using harsh chemicals or abrasive materials.
• Storage: When not in use, store the system in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

6.1 No Sound Output

• Check if the receiver and all active bodypack transmitters are powered ON.
• Verify that the headset microphones are securely connected to the bodypacks.
• Ensure the receiver's audio outputs are correctly connected to your mixer/amplifier.
• Check the volume levels on both the bodypack transmitters and the receiver.
• Confirm that the bodypack transmitters are correctly synchronized to the receiver channels.

6.2 Signal Interference or Dropouts

• Ensure the receiver antennas are fully extended and positioned optimally.
• Check for other wireless devices operating on similar frequencies in the vicinity.
• Move the receiver closer to the transmitters, staying within the 50m (164ft) operating range.
• If possible, try changing the operating frequency of the affected channel.

6.3 Short Battery Life

• Ensure you are using fresh, high-quality AA batteries.
• Battery life can vary based on battery brand and capacity.

7. Specifications

8. User Tips

• Always use high-quality alkaline or rechargeable AA batteries for the bodypack transmitters to ensure consistent performance and maximum battery life.
• Before a critical performance, test all channels and microphones to confirm proper synchronization and signal strength.
• Keep the receiver's antennas clear of obstructions and position them for line-of-sight with the transmitters whenever possible to maximize range and minimize interference.
