Description
The dbx ZonePRO 641m is a digital zone processor with six inputs and four output zones for commercial installations. Its pre-configured architecture keeps the inputs and outputs fixed, and the front panel carries a power LED, a network traffic LED and an RS-232 control port.
Inputs include four balanced mic/line inputs on terminal blocks with mic gain on each channel and two mono-summed pairs of unbalanced RCA inputs. Two input insert positions and one output insert position take channel-specific processing, and AutoWarmth on each output zone keeps the full frequency range when the level is turned down. A link bus copies the audio channels to another ZonePRO device. ZonePRO Designer software runs the Configuration Wizard and controls the unit over Ethernet or RS-232, third-party control systems connect the same way, and optional ZC wall controllers handle volume, source and preset changes.
