Note for programs 16-20 and 22-26
Send the signal you want to equalize through Narrow Boosts 1-5 to find the frequency that
may be most objectionable. Take note of that frequency for further editing or just set the
DEQ230 to the Narrow Cut 1-5 program that matches the Boost program that emphasized
the frequency range in question.
16 Narrow Boost 1 (80Hz)
17 Narrow Boost 2 (250Hz)
Split a full-range mono signal into both channels; send the output
of Channel A to an amplifier feeding the woofers and send
Channel B to an amplifier feeding the tweeters.
Some signals have 60Hz hum no matter what you do. This
program de-emphasizes 60Hz and its harmonics without taking a
noticeable bite out of the sound.
Use this as an effect to simulate what signals sound like passing
through the phone.
This program reduces sibilance--the sound when vocals' "S"
sounds are out of proportion to other phonetics.
