AVer COMEXSP20 Voice Conferencing Device

The AVer COMEXSP20 is a dedicated voice conferencing device built for meeting rooms and huddle spaces. It provides clear audio pickup and playback for group calls without requiring a separate phone system. The unit connects directly to a host computer or UC platform for immediate use. It suits teams that need a simple, plug-and-play speakerphone for daily collaboration.

20M Expansion Microphone Support

The defining specification is the 20 metre expansion microphone capability, which determines whether the unit covers your room size. This range allows additional microphones to be placed far from the base unit for larger tables. If your meeting space exceeds this pickup distance, the device will not capture every participant clearly. Buyers needing coverage beyond 20 metres should consider a different conferencing solution.

Sustained Meeting Performance

During long conferences the speakerphone maintains consistent audio quality without signal drop-off at the rated expansion distance. The hardware handles continuous voice transmission and echo cancellation for extended sessions. Thermal design supports uninterrupted operation through back-to-back meetings. There is no degradation in pickup sensitivity or output volume over time.

Questions about this item

How does the 20M expansion speaker affect audio coverage in a meeting room?

The 20M expansion speaker extends the pickup and playback range so participants farther from the base unit are heard clearly without moving closer to the device.

What connection standard does the COMEXSP20 use to link the expansion speaker?

The expansion speaker connects through the proprietary interface designed for the COMEXSP20, ensuring a direct wired link without relying on Bluetooth or Wi-Fi.

What physical space is needed to place the expansion speaker on a table?

The compact speaker unit sits flat on any conference table and requires only a small footprint near a power outlet for the wired connection.
