Frequently Asked Questions - WR 90E American Audio
How do I connect the WR 90E receiver to my mixer?
Connect the XLR or 1/4" output from the receiver's rear panel to a corresponding input on your mixer. Ensure both devices are powered off before connecting.
What is the maximum operating range of the WR 90E?
Under optimal conditions, the range is approximately 300 feet (90 meters) line-of-sight. Obstacles like walls can reduce range.

Can I use multiple WR 90E receivers together?
Yes, multiple receivers can be used in the same location. Ensure each receiver and its paired transmitter use different frequencies to avoid interference.
How do I clean and maintain the receiver?
Use a dry, soft cloth to wipe the exterior. Avoid liquids and abrasive cleaners. Keep the ventilation slots clear of dust.
Why is there no sound from the receiver?
Check that the receiver and transmitter are powered on, set to the same frequency, and the transmitter's audio is not muted. Also verify the output cable is connected correctly.
What is the squelch control for?
The squelch control adjusts the threshold for the receiver's mute function. Set it to the minimum level that eliminates background noise without cutting off the desired signal.
