Popular FAQ
Can multiple receivers listen to one Auracast™ transmitter at the same time? ›
Yes. Auracast™ allows one transmitter to broadcast audio to multiple receivers simultaneously. This is ideal for family TV watching, group tours, classrooms, churches and assistive listening environments.
Does Bluetooth® 5.3 automatically mean Auracast™ support? ›
No. Bluetooth® 5.3 alone does not guarantee Auracast™ support. The device must also support Bluetooth® LE Audio and be designed for Auracast™ functionality.
Can iPhone or Android phones receive Auracast™ audio? ›
Currently, phones generally cannot work as direct Auracast™ receivers. However, a compatible phone can work as an assistant device to help manage Auracast™ receivers and select broadcast sources.
Can regular Bluetooth earbuds receive Auracast™ audio through the app? ›
No. The MoerLab Audio App cannot turn non-Auracast™ earbuds into Auracast™ receivers. The receiving device must support Auracast™ or Bluetooth® LE Audio.
Hearing Aid Compatibility
Which hearing aids are compatible with MoerLab® transmitters? ›
Tested compatible hearing aids include Oticon Intent™, Starkey Edge AI™, ReSound™ Nexia™ and Jabra™ Enhance Pro 20.
Which sampling rate should I use for Auracast™ hearing aids? ›

TV hearMore™
Does TV hearMore™ support Dolby® Digital input? ›
No. TV hearMore™ does not support Dolby® decoding. Please set your TV audio output format to PCM.
Can I keep my TV speakers active while using TV hearMore™? ›
Some TVs support simultaneous audio output from optical Toslink and built-in speakers. For 3.5 mm and HDMI ARC outputs, the TV may disable its built-in speakers. Please check your TV’s audio output settings.
Does TV hearMore™ support audio output from a laptop HDMI port? ›
No. Laptop HDMI ports usually output video and audio to external displays, but they normally do not support HDMI ARC audio return. TV hearMore™ should be connected to a compatible TV HDMI ARC port, optical output or AUX output.
Why is there no audio when using the microphone input? ›
Please press the sound-source selection button until the LED indicator turns yellow, which indicates microphone input mode.
MoerDuo™ & MoerDuo Plus™
What is the difference between MoerDuo™ and MoerDuo Plus™? ›
MoerDuo™ supports both TX and RX modes. MoerDuo Plus™ is optimized as a stronger receiver solution with enhanced output power, especially suitable for T-coil hearing loop applications.
Can MoerDuo™ work as both transmitter and receiver? ›
Yes. MoerDuo™ supports both TX and RX modes. However, it cannot operate in TX and RX modes at the same time.
Can MoerDuo Plus™ work with a T-coil hearing loop? ›
Yes. MoerDuo Plus™ supports T-coil hearing loops, including compatible loops from other suppliers. It is recommended when stronger output is required.
Why does the MoerDuo Plus™ volume not seem to change? ›
Please press and hold the volume button steadily for about 1 second. If the button is pressed too quickly or too briefly, the volume change may not be registered.
How do I switch Auracast™ channels without using the app? ›
Quickly triple-click the main function button. You will hear “Broadcast Scanning”, and the receiver will search for the next available Auracast™ broadcast.
How do I reconnect after moving out of range? ›
Return within range and quickly triple-click the MFB button. The receiver will scan and reconnect to the available Auracast™ broadcast.

Does SoundLinker™ support USB audio transmission? ›
Yes. Please make sure the USB cable supports data transmission. Charging-only cables may not work for audio input.

Why isn’t MoerLink™ transmitting Auracast™ as expected? ›
After connecting MoerLink™, please start playing audio on your computer or mobile device. Auracast™ transmission may not start until an active audio signal is detected.
