Conference USB audio system AUDIOCODES RX40 with 2 satellite microphones

AUDIOCODES RX40 is a USB audio system designed for conference and meeting rooms, supplied with two satellite microphones. It connects via a single USB cable to a PC or conferencing device and captures clear voice from multiple positions to improve audibility during calls and recordings. The system is intended for small to medium group meetings and supports typical unified communication platforms without requiring complex installation.

Advantages

The RX40 provides multi-microphone coverage with two satellite microphones that extend voice pickup across a conference table. USB connectivity offers plug-and-play integration with Windows and macOS environments, minimizing setup time. The system focuses on voice clarity and consistent pickup from different seating positions, reducing the need for participants to lean toward a single microphone. Designed for meeting rooms, the RX40 combines compact hardware with straightforward operation.

Suitable for

• Small conference rooms and huddle spaces
• Remote and hybrid team meetings
• Webinars and audio-recorded interviews
• Unified communications platforms and softphone calls

Key specifications

• Connection: USB (single-cable connection to host device)
• Microphone configuration: central unit with two satellite microphones for distributed pickup
• Compatibility: standard USB audio class support for compatibility with common operating systems and conferencing applications
• Intended room size: small to medium meeting spaces

How to use

Connect the RX40 to a computer using the supplied USB cable; the device is recognized as a USB audio peripheral. Position the central unit and place the two satellite microphones on the table where they can capture participants’ voices without obstruction. Select the RX40 as the input and output device in the conferencing application or operating system audio settings. Adjust participant behavior—sitting naturally and speaking at normal volume—to ensure optimal pickup and intelligibility.

Recommendations

For best results, place the satellite microphones evenly around the speaking area and avoid covering microphone elements. Use the RX40 in rooms with moderate reverberation and reduce background noise where possible. When using different conferencing platforms, verify the selected USB audio device in the app settings and perform a brief audio check before important meetings.
