PEQ 3000 User Manual
• • DEEP: The deep bass response provides a slightly steeper gradient
than the classic, and it is uniquely shaped to provide minimum
harmonic disruption to the equalised source. As for the classic EQ, this
provides better differentiation and minimal phase shift, but there is no
undershoot error. Powerful boost/cut can be used that still sounds very
natural and does not alter the mid-range. This is best used on single
source material.

• • FREQ: The circular frequency control dial adjusts the EQ band frequency
from 2 Hz to 22 kHz
• • LO CUT or High Pass Filter (HPF): The Lo Cut attenuates all frequencies
below a certain level (cut-off frequency) while allowing all those above
it to pass through. The harshness or smoothness with which the sound
is removed beyond this point is determined by the dB/octave slope
selection, with 6 dB being the most common, and 12 and 24 dB are also
available. The Lo Cut is generally used to take rumble or hum out of any
sound source, but may also be equally-well used to produce a sound
effect by manipulation of the controls
• • HI CUT or Low Pass filter (LPF): The Hi Cut attenuates all frequencies
above a certain level (cut-off frequency) while allowing all those below
it to pass through. The harshness or smoothness with which the sound
is removed beyond this point is determined by the dB/octave slope
selection, with 6 dB being the most common, and 12 and 24 dB are also
available. The Hi Cut is generally used to reduce noise in quiet passages
with excessively high frequencies, but may also be used to produce a
sound effect, like a filtered drum roll, by manipulation of the controls
