Custom EQ Inside the Amplifier with Pro Audio Technology Programmable Modular Amplifiers (PMA)


An intuitive user interface with new predefined and parametric filters simplifies complex system calibration.

Huntington Beach, CA - September 25, 2012 - Pro Audio Technology (PRO), leader in professional-grade loudspeaker and digital amplifier technology, today announced enhancements to its Programmable Modular Amplifier (PMA) multichannel amplifier/processors. A complete family of new DSP filters for system acoustic optimization is now available via the PMA Control Panel™ interface - an enhancement to PRO's PMA Manager™ amplifier control software.

Using PMA Manager Software, an installer can configure PMA amp/processors for all PRO loudspeaker systems via a single mouse-click by simply selecting the loudspeaker model from a list. The user is then able to optimize performance of the system in-situ via easy-to-use drop down menus of predefined filter selections identified using plain English - no knowledge of engineering terminology or advanced acoustical principles is required. These features greatly simplify the system setup process and reduce system calibration time.

Up to four predefined acoustic filters are available, per channel.

Examples of the predefined filters include:

• Perforated projection screen high-frequency compensation, selectable by screen brand and model
• Acoustic fabric high frequency compensation
• Acoustic boundary loading compensation
• Bass response contouring to fine-tune boundary compensation
• Treble response contouring to fine tune screen and fabric compensation
• High and low pass filters for deployment of distributed audio subwoofer/satellite systems

In lieu of the predefined filters, advanced installers can make use of up to eight customizable parametric filters - per channel - plus delay and gain adjustments to fine tune low-frequency in-room audio performance. Designed for subwoofer optimization, all the tools required to tame room-related standing wave modes are available right in the amplifier and are implemented via PMA Manager Software.

In addition to the full-set of customizable and predefined filters, PMA Manager features a built-in pink noise signal to aid in diagnosis of system wiring and design issues, and provides signal routing within the PMA amplifier making the deployment of complex, multi-way, multi-speaker installations simple and efficient.

"Installers don't want to deploy stand-alone, multi-channel audio processors that add noise and use hard-to-understand terminology to get the best performance from their client's systems," said Paul Hales, Pro Audio Technology founder. "They are expensive, and needlessly complicate system wiring schemes. Our PMA amplifier/processors allow full optimization of audio systems right inside the amplifiers themselves. And best of all, PMA Manager™ with PMA Control Panel™, makes the process point-and-click easy."

Pro Audio Technology's Programmable Modular Amplifier is a 2U, four-channel design employing installer-programmable DSP with system calibration capabilities. PMA amplifier/processors are available in multiple configurations of 200, 450, or 1000 watts per channel. With high resolution DSP filtering, and proprietary PMA Manager Software, PMA amplifier/processors provide an intelligent, easy way to carry out complicated calibrations with minimal added cost and effort.
