Overview

12 x 8 Professional Audio DSP Mixer

CONVERGE Pro 2 is the industry’s most advanced professional audio DSP platform for conferencing and sound reinforcement applications. It outperforms in any size room, audio environment, and application.

The 128SR sound reinforcement model mixer has 12 inputs, 8 outputs, USB audio; GPIO, RS232, IP control interfaces; and P-Link and C-Link expansion buses. The 128SRD extends the connectivity of the base model with Dante digital audio interfaces.

CONVERGE Pro 2 SR is optimized to work with the DIALOG® 20 2-Channel Wireless Microphone System through its native connection.
