SPON Communications, a leading provider of intelligent audio IoT solutions, has focused on audio research for over 20 years. Based on market demands, SPON has developed the 【Unbounded】series Digital Conference System, specifically tailored for small- to medium-sized conference room deployments. With no need for dedicated connection cables, the installation process is simpler and more efficient.

 2. System Overview

The 【Unbounded】Digital Conference System is an entirely self-developed product by SPON, combining the stability of wired systems with the flexibility of wireless technology. This digital conference system supports video tracking, conference sign-in, voting, and decision-making functions, meeting the needs for local sound reinforcement, conference recording, and remote telephone conferencing.

The system's core is the conference host, which simultaneously manages both wired and wireless speaker units. The host integrates features for conference discussions, video tracking, and device control. It supports external Bluetooth audio input, making it easy to connect mobile phones or computers for playing audio or initiating remote meetings. The host also features a built-in Wi-Fi hotspot, allowing users to log into the system from a phone, tablet, or PC to adjust various system parameters. Additionally, the host supports 100M Ethernet transmission and can be expanded to connect with other SPON ecosystem products.

The speaker units offer diverse options, including square short-stem and gooseneck microphones, available in both wired and wireless configurations. For units without display screens, the panel patterns can be customized, while those with touch screens can upload personalized logos. High-fidelity audio capture and fully digital transmission ensure secure, stable, and seamless communication. All speaker units support EQ and volume adjustment, with an automatic mixing algorithm enabling up to 10 microphones to operate simultaneously, allowing for smooth and natural conversations.

3.Core Features

3.1 Speech Management

The speaker units are equipped with a 4.3-inch full-color touchscreen. Advanced speech control functions such as first-in-first-out, queue requests, and time-limited speaking are available. This makes it easy to manage who speaks, ensuring efficient meeting operations.

3.2 Conference Administration

The system includes a dedicated cross-platform conference administration software designed for large-scale conferences such as those held by governmental and legislative bodies. The software supports agenda management, conference check-in, voting, and decision-making procedures. The check-in and voting results are displayed in real time, ensuring transparent decision-making and smooth meeting operations.

3.3 Meeting Minutes

During the meeting, users can insert a USB drive to record audio from up to 16 separate speaker channels. The system supports real-time audio transcription through speech recognition software, converting speech into text to help quickly organize meeting minutes. This feature is invaluable for ensuring an accurate and timely record of discussions.

3.4 Parameter Adjustment

The system offers wireless parameter adjustment through PC, phone, or tablet devices. By accessing the system via a web page or UI interface, users can adjust various parameters in real time. Each speaker unit's input volume, AGC (Automatic Gain Control), EQ, and other audio settings can be individually adjusted or modified collectively, providing full control over the audio environment.

3.5 Flexible Deployment

The system can be deployed flexibly according to the size and functional needs of the conference room. It supports wired, wireless, and hybrid networks of both wired and wireless configurations. This adaptability ensures that the system can meet the demands of various conference settings, whether it’s for small-scale internal meetings or larger, more complex setups.
