ZonePro

Digital Zone Processor

™

®

The ZonePro TMproducts have been created to provide state-of-the-art signal processing for
Background Music (BGM) applications, while maintaining a simple, secure and intuitive
interface. From the powerful DSP modules to the multiple control interfaces, the ZonePro
products provide all the processing and control necessary for BGM installations.
Additionally, the GUI interface and Wizard function allows any contractor to quickly set up
and optimize the unit to its full potential by streamlining the setup process and providing a
menu based setup procedure that includes system setup and configuration.

The ZonePro products are based on the same unparalleled design philosophy that made the
DriveRack family famous. This philosophy, “To provide everything you need between the
sources and the amplifiers,” creates a full featured processor capable of almost any BGM
application. The ZonePro products offer two mic/line inputs on Euroblock connectors, and
four line inputs on mono-summing dual RCA jacks. Outputs are also on Euroblock con­nectors. Each input channel provides EQ, while the mic/line inputs also offer two DSP insert
blocks with a selection of Compression, Notch Filtering, Auto Gain Control, Advanced
Feedback Suppression (AFS™), Gating, and De-Essing. Each output zone provides a routing
matrix where each of the inputs can be selected as the main source or priority source. Paging
can be done from the Mic/line inputs; both paging and priority override offer full Ducking
capability. Each output also provides Autowarmth®, full Bandpass and Crossover filtering,
Parametric EQ, a selectable Dynamics module and output Delay. For more information

The Professional’s Choice In Signal Processing

™

Architects’ and Engineers’ Specifications:

The device shall provide two balanced inputs that are selectable as line or mic level with phantom power; additionally there shall be eight mono-summing RCA line inputs,
and one S/PDIF input. The line inputs and output gains shall be controllable via software; the mic inputs shall be adjustable from the rear panel. Audio inputs and outputs
shall be accessible via rear panel RCA and Euroblock connectors.

The signal processing Graphic User Interface (GUI) software shall be user programmable using Windows®, 2000, and XP operating systems. Software control shall be via RS­232 and Ethernet protocols and the DB-9 and RJ-45 connectors shall be located on the rear panel. The GUI shall provide display, configuration and control of all signal pro­cessing functions including, but not limited to: • Input Gain • Highpass Filtering • Parametric Equalization • Compression • Limiting • Gating • Automatic Gain Control •
Ducking • De-Essing • AutoWarmth® • Advanced Feedback Suppression (AFS™) • Notch Filters • Signal Routing • Bandpass Filtering • Delay • Polarity

Front panel controls shall include output zone volume, source select, and muting for each zone and dynamic page selection for both page inputs (1260 only). A PC DB-9 con­nector shall also be located on the front panel (1261 only). The front panel shall also include output level meters with a 6-segment LED meter and output dynamics threshold
LED (1260 only).

External control shall include scene selection, output level control and muting, and shall be via industry-standard CAT5 cable with RJ45 connectors. All program memory shall
be non-volatile providing program security should power or computer fail.

Audio conversion shall be 24-bit 48 kHz. The dynamic range of the processor shall not be lower than 110 dB A-weighted.

The device shall have an IEC power socket. The unit shall meet UL/CSA and CE safety requirements. The unit shall be constructed of cold-rolled steel with a brushed and
anodized aluminum front panel, and mount into a standard 19” 1U EIA rack. The device shall be a dbx ZonePro 1260 or 1261.
