MedBridge USB/Bluetooth Pro Speakerphone with Chain-Link Expansion
and engineering support
The BG-SpeakP300-C is a professional-grade meeting speakerphone designed for modern conference rooms, collaboration spaces, and hybrid work environments. Engineered for clarity and scalability, it delivers high-quality audio performance for both small huddle rooms and larger meeting spaces through an innovative daisy-chain design.
Supporting both USB and Bluetooth connectivity, the BG-SpeakP300-C offers flexible deployment with laptops, PCs, and mobile devices. Advanced audio processing technologies, including acoustic echo cancellation, noise reduction, and full duplex communication, ensure natural, interruption-free conversations across popular UC platforms such as Zoom and Microsoft Teams.
The BG-SpeakP300-C is available in standard audio and advanced noise cancelling versions, allowing users to select the optimal model based on room acoustics and ambient noise conditions.
Features In-Depth
At the core of the BG-SpeakP300-C is a four-microphone omnidirectional digital mic array with a pickup range of up to 5 meters. This allows voices to be captured clearly from all directions, making it ideal for roundtable meetings and collaborative discussions. The built-in 3W speaker delivers balanced audio output suitable for conference environments without distortion.
For larger rooms, the BG-SpeakP300-C supports daisy-chaining up to 9 identical speakerphones, dramatically expanding both microphone pickup and speaker coverage. This modular approach allows integrators and end users to scale audio coverage as room size or seating layouts change, without sacrificing sound quality or system simplicity.
Ease of use is a key design focus. The speakerphone features intuitive touch controls with LED indicators for mute status, volume level, and Bluetooth pairing. Plug-and-play USB audio (UAC) support ensures fast setup with no drivers required, while broad OS compatibility makes it a reliable choice for mixed-device environments.
Active NC vs NC Off
The BG-SpeakP300-C will be available in two versions to accommodate different meeting environments and user preferences: a Noise Cancelling model and a Standard Audio model (non-noise cancelling). Both versions share the same core hardware design, connectivity options, microphone array, and daisy-chain scalability, ensuring consistent performance and system compatibility regardless of the selected model.
The Noise Cancelling version incorporates advanced digital noise suppression technology designed to actively reduce background sounds such as HVAC noise, keyboard typing, paper movement, and ambient office chatter. This model is ideal for open offices, shared workspaces, classrooms, and acoustically untreated rooms, where environmental noise can interfere with speech clarity. By minimizing non-voice audio, it delivers cleaner, more focused communication for remote participants.
The Standard Audio version does not apply aggressive noise filtering, preserving the full natural sound profile of the room. This makes it well-suited for quiet conference rooms, boardrooms, executive offices, and studio-style environments, where accurate voice tone, spatial awareness, and natural room acoustics are preferred. It is also advantageous in situations where multiple speakers or subtle audio cues need to be captured without digital suppression artifacts.
