The dbx ZonePRO 640m 6x4 Digital Zone Processor is designed for professional audio applications.

The dbx ZonePRO 640m 6x4 Digital Zone Processor is designed for professional audio applications. It features 6 inputs and 4 outputs, allowing for flexible signal routing. The unit includes 4 independent six-segment lightpipe output meters that range from -30 to +20 dBu. An LCD display provides information about source selection, page steering, zone volume, and mute. Inputs include 6 total (4 switchable mic or line, 2 unbalanced, mono-summed RCA input pairs).

The processor offers a common mode rejection ratio of >40 dB, typically >55 dB at 1 kHz. Mic gain range is 30 to 60 dB. The equivalent input noise (EIN) is < -118 dBu, with a 150-ohm source impedance. Phantom power for mic inputs is +15 VDC. Outputs include 4 total, with an output impedance of 120 ohms balanced and 60 ohms unbalanced. The maximum output is +20 dBu. It uses dbx Type IV conversion system, has a sample rate of 48 kHz, and a typical THD+N of 0.003% at +4 dBu, 1 kHz, 0 dB gain.
