DBX ZONEPRO 640M 6×4 Digital Zone Processor

The ZonePRO 640m offers fixed I/O, pre-configured architecture, configurable insert processing and optional duplication of audio channels to another ZonePRO device via a link bus.

The 640m features a total of six inputs and four outputs. Inputs include four balanced mic/line switchable terminal block inputs and two mono-summed pairs of unbalanced RCA inputs. Hardware-controlled microphone gain allows adjustment of microphone gain per channel.

The 640m device has a pre-configured architecture with input processing, a central matrix and output processing. Two input insert positions and one output insert position allow channel-specific insert processing to be configured. AutoWarmth®, a psychoacoustic function that maintains full frequency bandwidth even when the signal level has dropped, is permanently available on each output zone.

A link bus allows duplication of the first six audio channels to another ZonePRO device in applications where additional output zones are required.

The front panel of the 640m features comprehensive signal metering, an informative LCD display and user-specified front panel control.

Additional system control is offered in the form of optional Zone Controllers. This collection of hardware wall-controllers represents a series of simple, elegant user interfaces for functions such as volume, source and preset control.

All ZonePRO devices can be controlled by third party control systems via RS-232 or Ethernet as applicable (see table for further information).

ZonePRO Designer—the configuration, control and monitoring software for the ZonePRO family of devices—offers control of the ZonePRO 640m via Ethernet or RS-232. The Configuration Wizard within ZonePRO Designer guides users through the step-by-step configuration process of the 640m.

Digital audio transfer of up to 32 IN/32 OUT channels

CobraNet (TM) is fully compliant with Ethernet, and is a highly practical solution for distributing audio and control data over a common Ethernet infrastructure. The NHB32-C features four separate 8-channel AES/EBU input/output terminals and uses CobraNet (TM) technology to transfer high-quality 20-/24-bit 48kHz digital audio over four-bundle* paths - in real time.

* One bundle contains 8 channels of 20-bit audio, or 7 channels of 24-bit audio.

MIDI, head amp remote(AD824) and amplifier control

The NHB32-C is designed to handle not only digital audio, but also control data as well. With this function, the unit can be used for one of three types of control*: MIDI, head amp remote (for the AD824 A/D converter) or for monitoring/control of PC-N power amplifiers connected to the ACU16-C.

* Only one control type can be used at a time.

Up to sixty-four channels of audio - with one Ethernet cable

CobraNet handles up to eight bundles of digital audio in multicast (one-to-all) mode on a single CAT-5/100Base-TX cable.Up to eight NHB32-C units can be networked, with each unit transferring four bundles and receiving four bundles, and 64 channels of digital audio can be picked up from any ACU16-C or NHB32-C connected on the network via CobraNet. A networked system with ACU16-C and NHB32-C is able to handle up to 64 channels of digital audio with CobraNet technology. Moreover, multicast and unicast (one-to-one) mode can be used in combination to optimize bandwidth, more than 64 channels of digital audio data can be transferred on a network system.

Line duplication for good reliable system

Primary and Secondary CobraNet (TM) ports are built into the system, providing an easy-to-use duplicate network for reliable operation. If one system fails, the other takes over seamlessly, ensuring absolutely stable performance.

The NAI48-ES is a digital audio network interface that uses the EtherSound network protocol. Digital mixing consoles such as the Yamaha PM5D, M7CL, or LS9 can be connected to AD8HR 8-channel microphone preamp/AD converter or DA824 DA converter units via the NIA48-ES for remote analog input or output interfacing on stage or wherever needed. This type of system eliminates noise problems that are unavoidable with conventional analog console plus multi-cable type setups, and dramatically reduces microphone cable length for superior sound quality. Cabling between the console and "stage box" units is also simplified for fast, easy setup.
