With 6 inputs and 4 outputs the dbx ZonePro? 640 and 641 provide flexible signal routing,
powerful DSP processing and multiple control interfaces for Commercial Audio applications.
Designed to offer superior system sonic performance and flexibility, the 640/641 deliver the
highest quality tools available. Even the input and outputs connectors were chosen for their
standard usage and reliability. The ZonePro products offer Euroblock connectors for balanced
signals and RCA connectors for interfacing with consumer equipment often used in commercial
applications; there is also a simple analog input buss that allows inputs to be sent from one
unit to the next for unit and job scalability. The 640 and 641 provide every necessary processing
tool, from the input processing like gain control and EQ available on all inputs to highly sophisticated
and specific functions such as selectable paging microphone processing including Gating,
De-Essing, Auto Gain Control, Compression and Feedback Suppression. The heart of the
ZonePro products is the Routing module that provides of course Primary Source Selection
but also Source Ducking for Paging and Priority Override. The outputs also offer a wealth of
processing designed for commercial applications like our patent-pending AutoWarmth? function
that was co-developed with JBL to provide natural low frequency extension at any signal level.
Each output also offers EQ, Bandpass and Crossover filters, Limiting and Delay for system
optimization. With the ZonePro? every tool is at your disposal to maximize the response of
your system.
Beyond processing, the ZonePro? products offer multiple forms of control to further extend the
versatility of your system. From easy-to-use wall panel Zone Controllers for standard end-user
functions like source select and volume control to advanced system control including a built-in
Real Time Clock that can provide programmable system changes throughout the day or week.
For system setup and monitoring the ZonePro Designer software provides an intuitive interface
and a speedy setup Wizard for configuring and editing all system parameters.

The ZonePro? 640 and 641 will take your Commercial Audio system to the next level with advanced
processing, versatility and control.

The ARX EC-2 is a flexible yet affordable 24 dB per octave Phase Correct active crossovers.
It has 2 modes of operation; as either Stereo 2 way or a Mono 3 way units, with a switch on
the back panel selecting either mode.

Features
Ultra low noise circuitry
Totally phase aligned at crossover point
Switchable Dual Channel 2 way or Single Channel 3 way
Unique 'semi-fixed' crossover point
24dB per octave (Fourth Order) Linkwitz-Riley filters
Separate Summed Mono Output
Balanced Inputs and Outputs
Built in High Pass filters
Intuitive, 'user friendly' layout
Flawless performance in any audio environment

Tamper-Proof Crossover Points
The crossover points are determined internally by the value of 4 resistors per channel; changing
the resistor value changes the crossover point. This 'semi fixed' method avoids the pitfalls of
externally adjusted crossover points, making the crossover points tamper-proof once they are set.
Idle fingers can't fiddle with the crossover points and create havoc with the system!
As a handy guide, a list of common crossover points and their corresponding resistor values are
printed inside the unit's lid, and also set out in the Owner's Manual.
On the front panel are level controls for Low and High in dual channel 2 way mode, and Low, Mid
and High in single channel 3 way mode, with corresponding Outputs on the rear panel.

Balanced Inputs and Outputs
EC-2 has Balanced Inputs and Outputs, on XLR connectors.
The EC-2 also has an additional summed Mono Low output, for applications that need a Mono Low
feed (e.g. Left and Right full-range plus a single Sub Bass speaker).
High Pass Filter
There is also a preset 30 Hz HighPass filter to remove unwanted subsonics which can damage speakers
and waste amplifier power.
In addition, each output has up to +6 dB of gain available, to compensate for amplifiers and speakers of
differing sensitivities.
Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240VAC, and is connected to the unit via a standard
IEC connector, with built-in fuse and voltage change switch.
Uncompromising Audio Quality
Innovative circuit design is pointless unless it delivers stunning sound quality, and here the EC-2 excels.
It has been designed for uncompromising audio quality, and to achieve this, Linkwitz Riley 24dB (Fourth
Order) state variable filters are used throughout, ensuring a smooth Phase Correct transition through the
crossover region.
From Stage Monitors to Studio Monitors, from Front of House to the Front room of your House, the ARX
EC-2 is a crossover that is suited to any application that requires flawless, transparent sound.
You'll never compromise on Quality when you choose ARX

The Soundweb London BLU-160 offers configurable I/O, configurable signal processing and a high bandwidth, fault tolerant digital audio bus.

The BLU-160 has open architecture which is fully configurable through HiQnet™ London Architect. A rich palette of processing and logic objects and a "drag and drop” method of configuration provide a simple and familiar design environment.

This processor features a low latency, fault tolerant digital audio bus of 256 channels which uses standard Category 5e cabling giving a distance of 100m between compatible devices. Fiber media converters can be used to increase the distance between devices to over 40km.

Four card slots which accommodate analog inputs, analog outputs, digital inputs and digital outputs in banks of four facilitate many different device I/O configurations.

Analog Input Cards provide software configurable gain in 6dB steps up to +48dB per channel and software selectable Phantom Power per channel. Digital Input Cards and Digital Output Cards process AES/EBU and/or S/PDIF audio and offer a variety of clocking and syncing options. (Further information about the I/O cards can be found on dedicated datasheets)

Phantom Power, Sync, Signal Present and Clip information per channel is easily accessible, without the requirement for a PC, from clear front panel LED indication. Device-specific information such as Device Name, Device Type, Firmware Version Number, Time, IP Address and Subnet Mask is available from the front panel display. A bi-directional locate function allows devices to be identified both from and within HiQnet London Architect.

12 Control Inputs and 6 Logic Outputs allow the BLU-160 to be integrated with GPIO compatible devices. The Soundweb London Interface Kit, comprehensive documentation which details how Soundweb London systems can be integrated with third party control systems, is included within the installation of HiQnet London Architect.

The BLU-160 and the other members of the Soundweb London family provide the building blocks of the perfectly tailored system solution.
