dbx ZonePro 641m - 6-Input/4-Output Digital Zone Processor with 4 Mic/Line Inputs and 2 RCA Input Pairs in Black Finish

The dbx ZonePro 641m is a versatile and robust 6-input/4-output digital zone processor designed to offer flexible audio management for a variety of applications. This unit is engineered with a comprehensive range of features that cater to both professional and consumer audio needs, making it an ideal choice for environments requiring precise control over multiple audio zones.

At the heart of the ZonePro 641m is its well-rounded connectivity. It includes four balanced mic/line inputs via Euroblock connectors and two mono-summed pairs of unbalanced RCA inputs. This configuration allows for a range of audio sources to be integrated seamlessly. The mic/line inputs are equipped with hardware-controlled gain adjustments, enabling precise microphone level control for each channel. With a maximum input line level of +20dBu for mic/line inputs and +12dBu for RCA inputs, the 641m can handle a variety of signal levels effectively. The balanced inputs offer high impedance (>50k?), and the RCA inputs are RF filtered to reduce interference, ensuring clean and reliable signal processing.

The ZonePro 641m features a pre-configured architecture, simplifying setup and operation. It includes two configurable input insert positions and one configurable output insert position for channel-specific processing, allowing for customization of the audio signal chain. The AutoWarmth feature, available on each output zone, maintains full frequency bandwidth even at reduced signal levels, enhancing audio clarity and depth.

A key aspect of the ZonePro 641m is its link bus functionality, which allows the duplication of audio channels to another ZonePro device. This feature is particularly useful for expanding the system to additional zones when more outputs are needed. The front panel of the device includes LED indicators for power status and network traffic, providing at-a-glance monitoring of the system's operation.

The device supports integration with optional Zone Controllers, which offer intuitive hardware interfaces for controlling volume, source selection, and preset configurations. For advanced system control, the ZonePro 641m can be managed via RS-232 or Ethernet connections, and it is compatible with third-party control systems. The ZonePro Designer software facilitates configuration, control, and monitoring of the 641m through Ethernet or RS-232, with a Configuration Wizard guiding users through the setup process.

In terms of performance, the ZonePro 641m is equipped with dbx Type IV conversion technology, ensuring high-quality A/D and D/A conversion. The dynamic range for line-level signals is greater than 113dB A-weighted, and the Type IV dynamic range exceeds 119dB A-weighted. The unit offers a frequency response of 20Hz to 20kHz, with minimal total harmonic distortion (0.003% typical) and excellent interchannel crosstalk (>80dB). The propagation delay is a minimal 0.6 milliseconds, ensuring accurate timing and synchronization of audio signals.

The dbx ZonePro 641m is housed in a 19-inch rackmountable chassis, with dimensions of 19 x 7.75 x 1.75 inches and a weight of 6.8 lbs. It operates on a range of voltages (100-230 VAC) and has a power consumption of 29 watts, with a BTU rating of less than 92.13.

Overall, the dbx ZonePro 641m offers a robust and flexible solution for digital audio processing, combining high performance with versatile control options to meet the demands of complex audio environments.
