Expansion Microphones POLY Trio 8300/8800 85X00AA HP

The POLY Trio 8300/8800 Expansion Microphones by HP extend the microphone coverage of Trio conference systems to support larger meeting spaces. Designed to connect directly with compatible Trio bases, these expansion microphones increase pickup range and help capture voices more consistently across the room. They are intended to complement the Trio 8300 and 8800 platforms and improve overall audio clarity for multi-participant conversations.

Advantages

These expansion microphones offer broader voice pickup and improved signal consistency when used with compatible Trio systems. Their seamless integration preserves echo cancellation and automatic gain features of the Trio platform while reducing dead zones in medium to large conference rooms. The microphones are engineered for easy setup and a compact footprint that maintains the room’s professional appearance.

Suitable for

• Medium and large meeting rooms where the Trio 8300/8800 base microphone range is insufficient
• Boardrooms and training rooms with multiple participants
• Hybrid meetings that require reliable audio pickup for remote participants
• Conference spaces where discreet, cable-connected expansion is preferred

Key specifications

• Designed for use with Poly Trio 8300 and 8800 conference systems
• Extended voice pickup range to cover larger room areas
• Wired connection to Trio base for synchronized audio processing
• Compact, low-profile design appropriate for tabletop placement

How to use

Connect the expansion microphones to the Trio base unit using the designated ports and cables supplied with the system. Position the microphones evenly around the table or room perimeter to minimize overlapping coverage and to ensure clear pickup of all speakers. After physical connection, verify in the Trio system settings that the expansion microphones are recognized and that audio processing features such as acoustic echo cancellation and automatic level control are active. Perform a brief sound check with participants in typical seating positions and adjust placement if necessary.

Usage recommendations

Place expansion microphones at recommended distances from the main Trio unit and avoid obstructing them with large objects. For optimal results in very large rooms, combine multiple expansion microphones with careful placement to achieve uniform coverage. Regularly check cable connections and software firmware on the Trio system to maintain consistent audio performance.
