Yamaha FX900 - Manual (Page 21)

The CDE distortion stage digitally produces smooth, rich
distortion that can be adjusted to achieve and extremeiy wide
variety of effects. In addition to providing fuil control of the
degree of distortion produced, a built-in noise gate function
with adjustable trigger level effectively shuts out unwanted
noise.
DST (Distortion Drive Level: 0 — 200)
Sets the degree of distortion produced. Higher vaiues
produce more distortion.
TGR (Noise Gate Trigger Level: -80----------30 dB)
Sets the threshold level of the distortion effect stage noise
gate. Signals below the threshold level are suppressed, thus
reducing noise. Caution: excessiveiy high TRG leveis can
cause notes to be cut off unnaturaiiy.
Distortion
LPF flow Pass Filter Cutoff Frequency: 500HZ — 16kHZ.
THRU)
Controls the tone of the distortion sound. Set at 500 Hz, oniy
signals below 500 Hz will be passed, resulting in a deep,
bassy sound. As the LPF frequency is increased more of the
totai frequency range is passed. When set to THRU, the LPF
is effectiveiy OFF and has no effect.
The CDE effect features a three-band equalizer stage for
wide ranging tonal control. Up to 15 dB of boost or cut can be
applied to the low, mid and high bands, and the center
frequency of the mid band can be adjusted over a broad 400
Hz — 6.3 kHz range.
Equalizer
L og fLow Gain: -15 — +15 dB)
Sets the amount of boost or cut applied to frequencies below
280 Hz. A setting of + 0 produces no boost or cut. Minus
vaiues produce cut and plus values produce boost.
MIGfMId Gain:-15-+15 dB)
Sets the amount of boost or cut applied to mid-band
frequencies. A setting of + 0 produces no boost or cut. Minus
values produce cut and plus values produce boost.
MIF (Mid Frequency: 400 - 6.3 kHz)
Sets the center frequency of the Mid equalizer band.
HIG miah Gain:-15-.fi5 dB)
Sets the amount of boost or cut applied to frequencies above
6.3 kHz. A setting of + 0 produces no boost or cut. Minus
values produce cut and plus values produce boost.
Passband
400 Hz 16 kHz
LVL (Output Level: -°°. -30 — -i-e dB)
Determines the output level of the CDE effect. The effect
output can be turn^ off by setting this parameter to -<x>. This,
however, means that any foiiowing effect stages also receive
no signai, and wiil produce no effect. Use the appropriate
front-panel EFFECT ON key to bypass the effect if
necessary.
