range are boosted.

Parametric EQ

Conventional Graphic Equalizer only allow you to adjust the level of
certain fixed frequency bands, Additionally. adjusting one fre-
quency band" may also affect the level of adjacent frequency
"bands".

The Parametric Equalizer, on the other hand, gives you four selec-
fable frequency bands with a choice of 27 different frequencies
from 40 Hz to 16 kHz Also, the band width can be set wide" or
"narrow" for each selected center frequency.

This will determine how adjacent frequencies are affected by level
adjustments in each band.
