“The LR500 squelch feature is a game-changer, allowing me to create a crystal-clear listening environment for my audience.” – John Doe, Audio Engineer
Using the SQ™ Feature
The Liten Technologis LR500 receiver has a special SQ™ (Super Quiet) feature. It cuts down on RF noise for better reception. This tech makes the sound quality and listening experience better for everyone.
To turn on the SQ™ feature, make sure the SQ switch in the LR500 receiver’s battery box is set to ON. Remember, you also need to turn it on at the transmitter and receiver for it to work right.
With SQ™ on, the system’s signal-to-noise ratio gets much better. This means you get cleaner and more enjoyable sound. The LR500 receiver can reach an amazing 80dB signal-to-noise ratio with SQ™ on, for super clear sound.
Without SQ™, the signal quality drops to 60dB for the 72MHz version and 50dB for the 216MHz version. This shows why using SQ™ is key for the best sound from the Liten Technologis system.
“The SQ™ feature is a game-changer, providing users with an unparalleled listening experience by minimizing unwanted noise and interference.”
The Liten Technologis LR500 receiver, with its SQ™ feature, offers top-notch audio quality. It lets users dive deep into their content, whether it’s for fun, learning, or work.
