FAQs

+What is the function of SQ?

To reduce noise of the systems, Listen offers a noise reduction technology called ListenSQ™. Both the transmitter and receiver must have SQ on to achieve the desired results. If you are planning to use this product with older Listen systems or equipment not manufactured by Listen, you should disable SQ.

+How many LR-100's can I use in a system?

As many as you need, the number is endless.

+Can I interface this to an amplifier or powered speaker?

Yes, both.

+Do I run the speakers in series or parallel?

It's your choice. However minimum impedance attached to LR-100 speaker amplifier must be greater than 4 ohms.
