the two third-octave or twelfth-octave spectra (measured in decibel units) to be sub-
tracted in real time. The difference shows the difference in the output spectra of the
two units under test, measured in dB.
Unless otherwise indicated, the measurements were made using the GREGG MX pre-
set in the 8600 and the GREGG preset in the 8500. These presets have essentially
identical loudness and are designed to have similar spectral balance in the midrange
frequencies and below. A higher reading in a given frequency band indicates that
that band has more power in the 8600 output than in the 8500 output.
HF Power Handling : Figure 3-5 on page 3-99 shows a typical HF improvement:
about 2.6 dB more average HF energy using the new technology. (Coincidentally,
there happens to be about 1 dB more energy in the 160 Hz band but this can easily
be matched more closely if the user wants.)
