As a project manager for a large team, I used to struggle with poor audio quality in our conference room—voices from the back of the room were barely audible. The A15’s daisy chain feature, extending its coverage from 4 to 10 meters, ensures everyone is heard equally, no matter where they sit. Plus, the Hi-Fi speaker delivers crystal-clear sound, making every discussion productive and inclusive.

I’m a consultant working with clients in various locations. Carrying bulky equipment used to be a hassle, but the A35’s sleek, portable design is a lifesaver. It’s easy to set up anywhere, and the Hi-Fi speaker provides exceptional sound clarity during presentations, leaving a great impression on my clients every time.

As a traveling executive, I need reliable audio solutions for impromptu meetings. The A15’s portable, elegant design is perfect for carrying on the go, and its 4-microphone array ensures clear, noise-free communication, even in challenging environments. It’s an essential tool for my busy schedule.

As an HR professional hosting hybrid meetings, the audio gaps between in-room participants and remote attendees used to create a communication divide. With the A35’s four microphones and outstanding noise cancellation, every voice is captured with clarity, making discussions seamless. The improved balance has significantly enhanced meeting effectiveness for our global teams.

I manage a nonprofit organization, often hosting roundtable discussions with multiple participants. Traditional audio systems left those at the far end of the table unheard. The A35’s daisy chain capability solved this problem, ensuring equal voice pickup throughout the room. Its Hi-Fi sound quality also makes it easier for everyone to focus and engage in meaningful conversations.

As a startup founder, our meetings often felt unequal—those farther from the mic struggled to contribute, and our old speaker distorted voices. The A35’s daisy chain feature expanded coverage across the entire room, while the Hi-Fi speaker ensured everyone could hear and be heard clearly. It’s transformed our team collaboration for the better.

What Daisy Chain Brings About?

One Wire, Double Expansion

Cascading two A15 speakerphones, you can double the sound pickup range and audio coverage, which ensures that the voices of all attendees in the room are captured and collected evenly and clearly, no matter where they are.

Hear More Clearly

Daisy-chaining allows for the distribution of sound at lower volumes across multiple speakers rather than blasting a single speaker at high volume. This reduces distortion and ensures that sound remains crisp and intelligible throughout the room

Simplified Setup and Cable Management

Instead of running separate cables from the audio source to each speaker, cascading speakers can simplify wiring. This reduces cable clutter and potential tripping hazards, making the setup more aesthetically pleasing and safer.

Cascade Realised In This Way

1. Connect one A15 speakerphone to your computer via dongle, USB-A/C cable or Bluetooth.

2. Connect two A15s with a daisy-chained line.

3. Selects A15 as the sound output device on your computer, which can realise the two devices to receive sound meanwhile, and output sound at the same time as well.

Scalability and Flexibility

Easily add or remove additional speakers as the needs of the room change, making it easier to adapt the audio setup to different room configurations or audience sizes.

Powerful Audio Technology

Powerful Noise Cancellation

Traditional conference rooms often suffer from disruptive noises like air conditioning, footsteps, and keyboard clicks, making it hard to focus and communicate. Our ProperClean2.0 technology insulates 99.99% of these noises, ensuring clearer communication and a more professional meeting environment.

Automatic Gain Control

With the help of AGC technology, the sound volume can be automatically adjusted within a range of 3m/10ft, which means that all participants sitting at different distances and speaking at different volumes can be heard equally clearly and evenly.
