+ Unique automatic mixing process delivers optimum intelligibility
+ 20 Hz-22 kHz bandwidth for full-range audio response
+ ALC & AGC keep participants’ audio balanced and consistent
+ Advanced Digital Processing on each amplifier channel

Configuration Flexibility
+ Four built-in 35 Watt amplifiers, 8Ω or 70V/100V
+ Up to 96 microphones
+ Link multiple Converge/Converge Pro units (Converge Pro 880, 880T, 880TA, 840T, 8i, TH20,
Converge SR 1212 and SR 1212A) for extensive microphone coverage and up to 16 phone
lines
+ Enhanced expansion bus, featuring 18 mix-minus audio buses for routing between units
+ Ten mic gating groups (four internal & six 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
+ No space required between rack mounted units
