2kHz:
Our ears are most sensitive to the octave centered
at 2 KHz. Reducing it can prevent ear fatigue while boosting
it will add immediacy, presence and “attack”.
8kHz:
The 8Khz control is the sparkle in the musical
spectrum. What is sometimes perceived as ear piercing treble
is actually much lower than this in the high midrange areas.
The tips of women’s vocals, snare drums, some synthesizer,
higher brass and woodwinds are in this area.
Para-BASS:
One equalization control to cover all your
various bass needs...we don’t think so. The unique Para-BASS
control in the FOUR.1 is flexible enough to satisfy the bass
requirements of audiophiles or true “bassheads”.
Sweep:
Pick a frequency between 40 and 80 Hz. The
lowest of lows and the frequencies you feel more than hear
live in the 40Hz range. If you want tighter, kick in the pants
bass, you will probably head more into the 80Hz range. As
you change frequencies the Para-BASS control automatically
adjusts the bandwidth or “Q” to the optimum level.
