dbx ZonePro 1261 - 12-Input/6-Output Digital Zone Processor with 2 Mic/Line Inputs in Black Finish

The dbx ZonePro 1261 is a sophisticated 12-input/6-output digital zone processor designed to enhance commercial audio systems with superior signal processing and control capabilities. This versatile device offers a robust set of features that cater to a wide range of audio applications, delivering high-quality performance and flexibility.

The 1261 features a comprehensive input and output configuration, including two balanced mic/line inputs via Euroblock connectors, eight unbalanced mono-summed RCA input pairs, and one S/PDIF input for digital audio. Each mic/line input allows for hardware-controlled microphone gain adjustments, providing flexibility in managing various signal levels. The balanced Euroblock inputs have an impedance greater than 50k? and are RF-filtered to minimize interference. The RCA inputs are similarly RF-filtered and have an impedance greater than 25k?. The maximum input line level is +20dBu for mic/line inputs and +12dBu for RCA inputs, ensuring compatibility with a range of audio sources.

The ZonePro 1261 is engineered with a pre-configured architecture that simplifies setup and operation. It includes input processing, a central matrix, and output processing. The device features two configurable input insert positions and one output insert position, allowing for precise signal processing tailored to specific needs. AutoWarmth, a psychoacoustic function co-developed with JBL, is available on each output zone, maintaining natural low-frequency response even at reduced signal levels.

The 1261 also includes a link bus, which allows duplication of audio channels to another ZonePro device, making it possible to expand the system and accommodate additional output zones as required. The front panel is equipped with comprehensive signal metering and an informative LCD display that provides real-time feedback on signal levels and system status. Additionally, the device includes user-specified front panel controls for convenient operation.

Control and configuration of the 1261 are further enhanced with Ethernet connectivity, allowing for remote access and control via standard network equipment. The device can also be controlled through optional Zone Controllers, which offer intuitive interfaces for managing functions such as volume, source selection, and presets. The ZonePro Designer software facilitates system setup and monitoring with its user-friendly interface and wizard-driven configuration process. This software, along with the built-in real-time clock, enables programmable system changes throughout the day or week.

In terms of performance, the ZonePro 1261 utilizes dbx Type IV conversion technology, ensuring high-quality A/D and D/A conversion with dynamic ranges exceeding 113dB A-weighted for line-level signals and 119dB A-weighted with Type IV dynamic range. The device offers 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 and crosstalk from input to output are both greater than 80dB, ensuring minimal signal bleed and high audio clarity. The propagation delay is a brief 0.6 milliseconds, maintaining precise audio synchronization.

Housed in a 19-inch rackmountable chassis, the ZonePro 1261 has dimensions of 19 x 5.75 x 1.75 inches and weighs 6.8 lbs. It operates on a voltage range of 100-240 VAC and has a power consumption of 27 watts, with a shipping weight of 8.8 lbs.

Overall, the dbx ZonePro 1261 delivers advanced processing capabilities, versatile control options, and high-quality performance, making it an excellent choice for enhancing commercial audio systems.
