Equalizer - Yamaha FX500 Operation Manual

ATK (Attack: 1.0 — 20 ms)
Determines how long it takes for compression to begin
after an input signal is detected. Higher values produce a
longer attack time, allowing more of the natural attack of
the input signal to come through. This parameter is
particularly useful if, for example, you want to retain a
sharp attack while increasing sustain.
LPF (Low Pass Filter Cutoff Frequency; 400 HZ —16
KHZ, THRU)
Controls the tone of the distortion sound. Set at 400 Hz,
only signals below 400 Hz will be passed, resulting in a
deep, bassy sound. As the LPF frequency is increased
more of the total frequency range is passed. When set to
THRU, the LPF is effectively OFF and has no effect.
LVL (Output Level: ^1 - +24 dB) LVL (Output Level:-41 -+6 dB)
Determines the output level of the effect. Determines the output level of the effect.
■
DISTORTION (DIST)
The FX500 distortion stage digitally produces smooth, rich
distortion that can be adjusted to achieve and extremely
wide variety of effects. In addition to providing full control of
the degree of distortion produced, a variable low-pass filter
gives you broad control over the tone of the distortion. A
built-in noise gate function with adjustable trigger level
effectively shuts out unwanted noise.
DST (Distortion Drive Level: 0 —100)
Sets the degree of distortion produced. Higher values
produce more distortion.
TRG (Noise Gate Trigger Level: -80-30 dB)
Sets the threshold level of the distortion effect stage noise
gate. Signals bebw the threshold level are suppressed,
thus reducing noise. Caution: excessively high TRG levels
can cause notes to be cut off unnaturally.
■
EQUALIZER (EQ)
The FX500 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.
FREQUENCY(Hz)
LoG (Low 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" values produce cut and "plus" values produce
boost.
