Bodypack Transmitters with Lavalier/Headset Mics
The bodypack transmitters provide flexibility for users requiring hands-free operation. They connect to either lavalier (clip-on) or headset microphones, ideal for presentations, teaching, or performances. Each bodypack also operates on AA batteries and includes volume adjustment.

Setup Instructions
- Power On: Connect the power supply to the AU800 receiver and plug it into an electrical outlet. Turn on the receiver using the power switch.
- Install Batteries: Open the battery compartments of the handheld microphones and bodypack transmitters. Insert two AA batteries into each unit, ensuring correct polarity.
- Automatic Linking: Once the receiver and microphones/bodypacks are powered on, they will automatically link. The RF indicators on the receiver will illuminate when a stable connection is established for each channel.
- Connect Antennas: Screw the provided antennas onto the corresponding ports on the rear of the receiver. Ensure they are securely tightened and positioned for optimal signal reception.
- Connect to Mixer (XLR Output): For individual channel control, connect XLR cables from the balanced XLR outputs on the receiver (Balanced A, B, C, etc.) to the XLR inputs on your audio mixer.
- Connect to Mixer (Mixed Output): Alternatively, for a combined output of all microphones, connect a 6.3mm (1/4 inch) audio cable from the 'Mixed Output' jack on the receiver to a line input on your audio mixer.
- Connect to Active Speakers (XLR Output): If connecting directly to active speakers, use an XLR cable from one of the balanced XLR outputs on the receiver to an XLR input on your active speaker.
- Connect to Active Speakers (Mixed Output): For a combined output to active speakers, use a 6.3mm (1/4 inch) audio cable from the 'Mixed Output' jack on the receiver to a line input on your active speaker.

Operating Instructions
- Microphone Power: Use the ON/MUTE/OFF switch on each handheld microphone or bodypack to power it on or off. The MUTE position temporarily silences the microphone without powering it down.
- Adjusting Volume: Each channel on the AU800 receiver has an independent volume control knob. Rotate the knob clockwise to increase volume and counter-clockwise to decrease it. Adjust these to achieve the desired audio level for each microphone.
- Signal Range: The system offers a wireless signal range of up to 80 meters (260 feet) in an open environment. Ensure clear line-of-sight between the microphones/bodypacks and the receiver for optimal performance.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Avoid using liquid cleaners or solvents.
- Battery Replacement: Replace batteries in microphones and bodypacks when the low battery indicator appears or when performance degrades. Always use fresh AA batteries.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures when not in use. Remove batteries if storing for extended periods.
- Antenna Care: Handle antennas carefully to prevent bending or damage. Ensure they are properly connected for optimal signal.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from microphone | Microphone/bodypack off; low batteries; receiver off; incorrect cable connection; mixer/speaker input issue. | Ensure microphone/bodypack is ON (not MUTE); replace batteries; check receiver power; verify all audio cables are correctly connected; check mixer/speaker input settings and volume. |
| Interference or static noise | Other wireless devices nearby; weak signal; environmental obstacles; incorrect frequency setting (less common with auto-link). | Move away from other wireless devices (Wi-Fi routers, other wireless mics); ensure clear line-of-sight between transmitter and receiver; reposition antennas; try a different location if possible. |
| Low volume or distorted sound | Microphone volume too low; receiver channel volume too low; input gain on mixer/speaker too low/high; microphone too far from source. | Increase microphone volume; adjust receiver channel volume; check input gain on connected audio equipment; ensure microphone is close enough to the sound source. |
| Microphone not linking | Microphone/receiver not powered on; out of range; battery issue. | Ensure both transmitter and receiver are powered on; bring transmitter closer to receiver; replace batteries. |
