AKG 3177H00010 CBL410 PCC VoIP Teleconferencing Microphone

The AKG CBL410 PCC is a boundary (pressure zone) microphone engineered specifically for the acoustic demands of VoIP conferencing. Placed flat on a table, the PCC design leverages the reflective surface to combine direct and reflected sound in phase, producing a clean, natural voice signal with consistent level from participants seated around the table. The signal processing targets intelligibility over extended frequency response — what you hear on the far end of a call is a clear, natural voice reproduction optimized for speech, not music or broadband audio.

The 3.5mm stereo jack connection means this microphone integrates with any PC or laptop in seconds — no interface box, no driver install, no audio routing setup beyond Windows sound settings. For organizations running a distributed conferencing setup, the cascading capability is the standout feature: multiple CBL410 PCC units can be linked together to cover longer tables or irregularly shaped rooms without adding complex hardware. The trade-off for this simplicity is limited control — there's no gain adjustment, no pad, no mute button, and no USB alternative. It works best in environments where the goal is reliable, repeatable voice capture without technical overhead.
