Q & A

Q1: Who is this product designed for, and what problem does it solve?
A: This system is designed for users who need real-time, low-latency audio. It reduces Bluetooth delay to about 30ms, making it suitable for live speech, synchronized sound, and group listening.

Q2: Which should I choose, Audiplex or AuraPlex?
A: Choose Audiplex (2.4G) if low latency is your priority for real-time audio and synchronized sound. Choose AuraPlex for Auracast broadcast listening, including use with compatible hearing aids or Auracast headphones.

Q3: What happens if multiple groups are using the system in the same venue?
A: The system supports multiple channels, allowing different groups to operate on separate channels at the same time. Each receiver can be set to a specific channel to avoid interference.

Q4: Is it easy for non-technical staff or volunteers to manage?
A: Yes. The system is designed for simple, plug-and-play operation. Users can power on the devices, select a channel, and start listening without complex setup.

Q5: Can I use this system for speaking, such as connecting a microphone so the audience hears me better?
A: Yes. You can connect a microphone, mixer, or other audio source using Optical, AUX, or Bluetooth input, and the audio is delivered wirelessly to receivers with minimal delay.
