4. Setup Guide

1. Unpack Components: Carefully remove all items from the packaging and verify against the "Package Contents" list.
2. Connect Antennas: Screw the four antennas onto the corresponding ports on the rear of the wireless receiver unit. Ensure they are securely tightened.
3. Power Connection: Connect the power adapter to the DC IN port on the receiver and plug the adapter into a suitable power outlet.
4. Audio Output Connection:
   • For unbalanced output, connect one end of the 6.35mm audio cable to the "MIX OUT" jack on the receiver and the other end to the input of your mixer, amplifier, or speaker.
   • For balanced output, use XLR cables (not included) to connect the "XLR OUT A" and "XLR OUT B" ports on the receiver to the balanced inputs of your audio equipment.
5. Insert Batteries into Microphones: Open the battery compartment of each handheld microphone and insert 4 AA batteries (not included), observing the correct polarity (+/-). Close the compartment securely.
6. Positioning: Place the receiver unit in a stable location, away from strong electromagnetic interference sources. Ensure the antennas are extended and unobstructed for optimal signal reception.

5. Operating Instructions

1. Power On:
   • Press the "POWER" button on the receiver unit to turn it on. The LCD screen will illuminate.
   • Press and hold the power button on each handheld microphone to turn them on. The microphone's LCD screen will display battery level and frequency.
2. Automatic Frequency Binding (Pairing):

   The DR80 system features an easy one-button pairing function to automatically avoid nearby interfering frequencies.

   • With both the receiver and microphone powered on, press the "IR" button on the receiver for the desired channel (Channel A or Channel B).
   • Point the infrared (IR) sensor of the microphone towards the IR window on the receiver. The system will automatically scan and pair to an available frequency.
   • The "AF" (Audio Frequency) and "RF" (Radio Frequency) indicators on the receiver's display should light up steadily when a successful connection is established.

3. Manual Frequency Adjustment:

   If manual adjustment is needed or to select a specific frequency from the 200 available options:

   • On the receiver, use the "SET" button and the arrow buttons (+ / -) to navigate and select the desired frequency for Channel A or Channel B.
   • Once the frequency is selected on the receiver, perform the "Automatic Frequency Binding" step (point microphone IR to receiver IR) to synchronize the microphone with the new frequency.
4. Adjusting Volume:

   Each channel on the receiver has an independent volume control knob. Rotate the "VOLUME" knob for Channel A or Channel B to adjust the output level of the corresponding microphone.
5. Monitoring Display:

   The LCD screens on both the receiver and microphones provide real-time information:

   • Receiver: Displays channel, frequency, signal strength (RF), audio level (AF), and mute status.
   • Microphone: Displays battery level and current operating frequency.
6. Mute Function:

   Briefly press the power button on the handheld microphone to toggle the mute function. The microphone's display will indicate "MUTE" when active, and the receiver's display will also show the mute status for that channel.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Do not use liquid cleaners or abrasive materials.
• Battery Replacement: Replace batteries in the microphones when the battery indicator on the LCD screen shows low power to ensure uninterrupted performance. Remove batteries if the microphones will not be used for an extended period.
• Storage: Store the system in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity.
• Handling: Handle microphones and receiver with care. Avoid dropping or subjecting them to strong impacts.
