Superior Audio Performance

+ Next-generation Distributed Echo Cancellation

®

on every mic input

+ First-mic priority delivers clear audio to the far end
+ 20 Hz-22 kHz bandwidth for full-range audio response
+ ALC & AGC keep participants’ audio balanced and consistent

Configuration Flexibility

+ Scalable – link multiple Converge/Converge Pro units (880, 880T, 840T, 8i, TH20, SR 1212)

for extensive microphone coverage and up to 16 phone lines

+ Enhanced expansion bus, featuring 12 mix-minus audio buses for routing between units
+ Eight mic gating groups (four internal & four global) allow separation of mics into

individual mixer gating groups for greater configuration flexibility

+ 32 presets can be executed on-the-fly without disturbing other ongoing preset operations
+ 255 Macros for customized audio control/configuration with single command execution

Professional Conferencing Input Expansion System

An input-only expansion box for the Converge / Converge Pro platform. The 8i
delivers new economical configuration flexibility. It can be added to 880, 880T,
and 840T systems for additional mic and line inputs, allowing customers to
match the number of inputs and outputs required for audio conferencing and
sound reinforcement applications.
