Airsync Wireless XLR Transmitter & Receiver Manual

Quick Start Guide


1. Set the transmitter to either mic or line mode before powering on. Use mic mode for microphones and line mode for devices like mixers.

2. For dynamic or ribbon microphones, set the voltage to 5V. Use 48V for condenser microphones. Avoid using 48V with ribbon microphones to prevent damage.

3. Connect the transmitter to a microphone or line device, and the receiver to the desired receiving device. To avoid clipping, connect devices before powering on.

4. Power on/off by pressing and holding the power button for 2 seconds.

5. Ensure the frequency on both the transmitter and receiver match. Change the frequency by double-clicking the power button on either device. The new frequency saves after 3 seconds. Devices are factory paired.

6. Charge the devices using the included USB cable.

Instructions For Using Multiple Airsync Units (Locking the Frequency)

AirSync units are shipped in an unlocked state which allows you to quickly change frequencies on the transmitter and have the receiver follow. If you want to use multiple sets simultaneously then you simply need to lock the frequency of each set. Locking the frequency will prevent the receiver from changing to any open frequencies of other transmitters and will only allow it to pair with the transmitter it was originally synced and locked to.

Here are step by step instructions for Locking the Frequency on Airsync Units

1 - Power on one set of AirSync units (transmitter and receiver). Make sure there are not any other AirSync units are powered on at the same time.
2 - Set the desired frequency: Turn on one set (transmitter and receiver) and adjust to the desired frequency by double clicking the power button on the transmitter. The receiver should change frequencies to match the transmitter automatically.
3 - Power off both your transmitter and receiver, still making sure that no other AirSync units are powered on.
4 - Long Press for Sync Locking: With your transmitter and receiver powered off, press and hold the power button. Do not release the power button until the next step is confirmed.
5 - Screen confirmation: Continue holding until the transmitter screen displays "ID: SYNC" and the receiver screen displays "ID: Unlock." Release the power buttons once the screens display these confirmations.
6 - Complete: Wait a few seconds after screen confirmation and then your Airsync units are frequency-locked. This means the receiver is now synced directly to the transmitter that you Synced and it will not connect to any other transmitter. You can now repeat this process if you own multiple sets of AirSyncs. Just make sure to turn off the pair that you just finished syncing.

AirSync Frequently Asked Questions

I'm hearing pop sounds through my PA system. Is this normal?
This can occur when a frequency is particularly crowded in your area. Try different frequencies for extended periods to see what performs best. This depends entirely on your location and other UHF devices in the area.
What's the frequency range of AirSync?
AirSync operates on 657.000–663.000 MHz.
How do I use multiple AirSync units simultaneously?
You need to lock the frequency of each set to prevent interference. Follow the locking instructions in the manual above and watch our video tutorial.
I'm getting hiss, hum, or noise from my AirSync. How do I fix this?
Check these settings:
• Mic/Line Mode: Use Mic Mode for microphones, Line Mode for mixers
• Voltage Setting: 5V for dynamic/ribbon mics, 48V for condenser mics
• Frequency: Try adjusting frequency if in a high-interference environment
My audio sounds distorted or has poor quality.
Make sure you're using the correct voltage setting (5V for dynamic mics, 48V for condenser mics) and the proper mode (Mic vs Line).
My AirSync battery isn't holding charge properly.
Sometimes batteries need a few charge cycles to reach optimal performance. If you've tried multiple charges and the issue persists, contact us for a warranty replacement.
How long does the battery last?
Up to 8 hours of battery life with quick USB-C charging.
Will multiple AirSync units fit side by side on my mixer?
Most soundboards won't fit multiple units side by side due to their thickness. Use an XLR 90-degree adapter or the included XLR to TS adapter to turn them sideways.
What's the wireless range?
AirSync offers up to 150 feet wireless range with less than 3ms latency.
How many units can I use simultaneously?
Up to 16 units can be used simultaneously on the UHF frequency band.
What types of microphones work with AirSync?
Both dynamic (5V) and condenser (48V) microphones.
Can I use AirSync with powered speakers?
Yes! AirSync can wirelessly connect your soundboard to powered speakers, perfect for portable events.
Is there any delay/latency?
Less than 3ms latency ensures real-time audio delivery.
My AirSync units won't pair or stay connected.
Make sure both units are on the same frequency. Double-click the power button on the transmitter to change frequency - the receiver should follow automatically.
How do I reset my AirSync?
Power off both units, wait a few seconds, then power them back on. This will reset the connection.
