Bộ xử lý tín hiệu âm thanh DBX DriveRack PA2
The dbx DriveRack PA2 Complete Loudspeaker Management System is a loudspeaker management system that can be controlled via your Mac, PC, or mobile iOS or Android device. Using an optional microphone connected to its RTA input, its AutoEQ function can be employed to listen to your room and automatically EQ it for optimized speaker performance. The AFS (advanced feedback suppression) feature is designed to eliminate feedback while preserving the sound of your system.
