General

The PB-800-DN Industry amplifier is an ultra-reliable, high-power, 8 channel (100W per channel) audio power amplifier designed for use in critical systems. It is designed to drive 100 V line loudspeaker systems and is equipped with on-board DSP allowing gain, EQ, delay and other parameters to be controlled from a remote location using WinControl software, via DANTE™.

The amplifiers are fully monitored, with automatic fault detection and reporting. Inputs may be either balanced analogue audio or digital audio DANTE™.

When used in conjunction with Duran Audio’s OpSTImizer® service the PB amplifiers can provide significant improvements in speech intelligibility within a tunnel.

Amplifiers

The full complementary class AB amplifiers are equipped with rugged industrial power mosfet devices capable of handling large currents without risk of failure. The large phase margin within the feedback loop keeps the amplifiers stable under any load condition.

Power Supply

The IndustryAmps are equipped with a high-power switch mode power supply. The power supply is specially designed for audio applications, featuring soft knee over current protection and very high peak power capability. Active power factor correction keeps the mains harmonics at low levels while increasing the input voltage range from 90V to 270V without interruption or manual changeover. A low-power stand-by switch mode auxiliary supply enables shut down of the main supply under network control.

Signal Processing Unit

A digital signal processor unit controls the amplifier units. The digital processing is performed by a 32 bit floating point DSP. The DSP software provides various functions in order to attenuate, delay, equalize, filter, compress or limit the separate audio signals for all individual output channels, or perform special algorithms necessary for dedicated active array control. All software is stored in non-volatile memory, enabling the unit to start up and operate autonomous without host control unit.

Inputs and Outputs

All power-amplifier outputs are equipped with high-grade toroidal output transformers to provide 100V/70V outputs. All loudspeaker terminals are protected by means of gas discharge devices against voltage spikes. Both analogue audio inputs are transformer isolated.

Network

The RISC also manages the network functionality of the device. By using a host PC, the user can monitor all surveillance related parameters, send "one line" control commands or upload new DSP code or process settings to any combination of addresses. All surveillance related and DSP related software inside the IndustryAmp is stored in non-volatile RAM, restoring the last settings automatically after power up.

Surveillance

The surveillance routines are performed by a RISC (reduced instruction set computer) which is located on the processor board. It monitors a large amount of surveillance related parameters. These include: pilot tone detection on all inputs, load monitoring on each output, temperatures of heat sink and ambient, amplifier functionality, fan speed, ambient noise sensing microphone presence and DSP status. The RISC software enables the IndustryAmp to take “intelligent” autonomous decisions such as switching to a second input channel in case a pilot tone is lost, or acoustical output level adaptation the to the ambient noise level without any central intervention. All possible reported failures can be mapped onto a dedicated failure relay.

The key to harnessing the powerful potential of an AXYS speaker system is the dedicated WinControl software – a highly developed, yet intuitive environment through which the system designer can access and set all functions and parameters.

WinControl has been developed for use with AXYS Intellivox Loudspeakers, as well as Target, G2 products (Source and Scope ranges), the PB Series of networked amplifiers and the recently released AXYS Octadrive DSP – a high performance line driver that can be used to interface between 3rd-party systems and AXYS products. This enables WinControl to provide system-wide status monitoring, even across products from different manufacturers.

As the name implies, the WinControl software runs on most varieties of Windows® OS on a standard PC. Communication, via RS-485, with the settings stored in non-volatile memory in the Intellivox units themselves, meaning the PC can be removed at the end of the process.

AXYS WinControl directly controls DDC-driven products, and enables the upload of DDA-calculated DDS directivity files. It is also used to define other audio parameters that are critical to achieving the full capabilities of an installation within a specific acoustic space. In short, it is WinControl that enables coherent, intelligable sound to be delivered to the areas where it is required, while steering it away from reflective surfaces that would cause unwanted reverberation.

Despite the extent and precision of control offered by WinControl, the in-house software development team has ensured that the user interface can be readily understood. Typically, parameters can be adjusted numerically, or scrolled up and down, with confirmation of the changes displayed graphically in real-time.

The inputs can be configured to work in one of three ways:

  • Inputs can be summed
  • Level controlled priority switching
  • Pilot tone controlled priority switching

Once the units have been configured, the PC can be removed from the network as the settings are stored in non-volatile memory.

The latest version of AXYS WinControl is available for immediate use or evaluation. Existing users are advised to check from time-to-time that they are running the most recent WinControl release.
