PARADIGM PERFECT BASS KIT™: user-selected measurement points (we suggest a minimum of five, but A TRUE AUDIOPHILE SOLUTION TO THE PROBLEMS OF THE ROOM up to ten can be measured), beginning with a measurement at the Step-by-step instructions for using the Paradigm Perfect Bass Kit are included in the following section but before you begin, a little about how PBK works on your room and what makes it better than any other digital primary listening position and then moving across the listening area. This process is critical to properly dealing with standing waves and ensuring optimal bass performance throughout the listening area. room correction system in the world: • Unlike many "Room EQ" systems, PBK applies Correction to Peaks • PBK is a state-of-the-art "bass perfecting" system that analyzes the subwoofer's response in your room, then sets the correct equalization parameters to attain optimal sound. The frequency response of each PBK microphone is measured precisely and the data is used to create (modes) and Dips (anti-modes). Tackling both allows us to achieve a far more accurate and natural room response. To limit the demands on the amplifier and maximize signal-to-noise ratio PBK applies appropriate limits to this correction. the microphone's calibration file included on the PBK software • PBK is Ultra-Accurate! The connected PC's 64-bit floating-point disk. The microphone can only be used with the matching individual processor does the hard work of calculating the correction curves, which calibration file. greatly minimizes rounding errors of a less sophisticated "calculator". • PBK applies Super-Efficient Infinite Impulse Response (IIR) Filters in addition to Paradigm's Custom Filter Topology to minimize delay and reduce processing gain noise. The combination of limiting the widths of our IIR filters and applying our topology means that any artifacts that might have resulted from the filtering process are so small as to • It's Easy to Use (we've done the hard work!). Three years of intensive research and development on our part have made it a snap to attain Perfect Bass performance in any room! All that's required is a PC running Windows XP, Vista or Windows 7*, 2 USB ports and the Paradigm Perfect Bass Kit. be completely inaudible.
