About the AF(Advanced Forcus) Method
This newly developed AD conversion process virtually eliminates
all quantization noise, and dramatically improves overall dy-
namic range. It accomplishes this by using two types of AD
converters (with different input levels) to convert audio signals into
data in combination with a unique DSP method for creating a
composite of the separately obtained data streams.
Since the GP-100 uses two 18-bit AD units for processing sound,
the length ofthe AD conversion data is extended to 22 bits after the
AF process. Actual test results have yielded a dynamic range in
excess of 118 dB in the GP-100's AD section, testifying to the
extremely clear sound quality that can be achieved with this
processing method.
