The dbx ZonePRO 640m is a powerful commercial audio processor designed for flexible zone management in restaurants, retail spaces, conference centers, houses of worship, and multi-room installations. With six inputs and four outputs, the 640m provides a highly adaptable DSP platform featuring pre-configured architecture, configurable insert processing, and advanced digital audio routing.
Four balanced mic/line switchable inputs and two mono-summed RCA inputs allow you to connect microphones, playback sources, paging systems, and background music feeds with ease. The 640m offers per-channel microphone gain, two input insert points, and an output insert point for precise signal shaping. Each output zone includes AutoWarmth®, a dynamic psychoacoustic enhancer that maintains full, rich sound even at lower volume levels.
A link bus enables duplication of up to six audio channels to another ZonePRO processor, making it effortless to expand your system into additional zones. The front panel provides clear metering, an LCD, and customizable user controls for quick access to essential functions.
Complete system management is available through Ethernet or RS-232, optional ZC wall controllers, and the intuitive ZonePRO Designer software, which guides users through setup and configuration with its step-by-step wizard. Designed for professionally installed audio applications, the ZonePRO 640m delivers reliable signal processing, flexible control options, and high-quality performance for any multi-zone environment.
