dbx ZonePro 1261m - 12-Input/6-Output Digital Zone Processor with 6 Mic/Line Inputs in Black Finish

The dbx ZonePro 1261m is a sophisticated 12-input/6-output digital zone processor engineered to handle complex audio routing and management tasks with efficiency and precision. This device is ideal for applications requiring extensive audio control and flexibility, making it suitable for both commercial and professional use.

The 1261m features a versatile set of inputs and outputs, including six balanced mic/line inputs via Euroblock connectors, four mono-summed pairs of unbalanced RCA inputs, and a digital S/PDIF input supporting up to two channels. Each balanced mic/line input offers adjustable microphone gain, accommodating a wide range of signal levels with ease. The balanced inputs have high impedance (>50k?) and are RF-filtered to ensure minimal interference, while the RCA inputs are also RF-filtered for clean signal processing. The maximum input line level is +20dBu for mic/line inputs and +12dBu for RCA inputs, providing flexibility in handling various audio sources.

The ZonePro 1261m employs a pre-configured architecture that includes input processing, a central matrix, and output processing. This design allows for straightforward setup and operation. The device features two configurable input insert positions and one output insert position, enabling precise channel-specific signal processing. AutoWarmth technology is available on each output zone, ensuring that the full frequency bandwidth is maintained even when the signal level drops, which enhances audio clarity and consistency.

A key feature of the 1261m is its link bus, which facilitates the duplication of the first six audio channels to another ZonePro device. This is particularly useful for expanding the system to include additional output zones as needed. The front panel of the device is equipped with LED indicators for power status and network traffic, as well as an RS-232 control port for integration with external control systems.

Additional system control is available through optional Zone Controllers, which provide intuitive hardware interfaces for managing volume, source selection, and presets. The 1261m can be controlled via RS-232 or Ethernet, and it is compatible with third-party control systems. ZonePro Designer software allows for configuration, control, and monitoring of the 1261m through Ethernet or RS-232, with a Configuration Wizard that guides users through the setup process.

In terms of performance, the ZonePro 1261m utilizes dbx Type IV conversion technology, ensuring high-quality A/D and D/A conversion. The device offers a dynamic range of over 113dB A-weighted for line-level signals and exceeds 119dB A-weighted with Type IV dynamic range. It provides a frequency response of 20Hz to 20kHz with a total harmonic distortion plus noise (THD+N) of 0.003% typical at +4dBu. The interchannel crosstalk is greater than 80dB, ensuring minimal signal bleed between channels. The propagation delay is a brief 0.8 milliseconds, maintaining precise audio synchronization.

Housed in a 19-inch rackmountable chassis, the ZonePro 1261m has dimensions of 19 x 7.75 x 1.75 inches and weighs 6.2 lbs. It operates on a voltage range of 100-240 VAC and has a power consumption of 27 watts, with a BTU rating of less than 92.13.

Overall, the dbx ZonePro 1261m provides a powerful and versatile solution for digital audio processing and zone management, combining advanced features with flexible control options to meet the needs of demanding audio systems.
