Lo Lvl Expander; Exciter Program; Exciter - Yamaha SPX1000 Operation Manual

37. LO LVL EXPANDER

The EXPANDER program allows efficient suppression of
low-level noise, contributing to a cleaner-sounding overall
signal. This i a stereo expander in which the highest signal
level – left- or right-channel - is used for gain control.
NOTE:
The EXPANDER program has no internal parameters.
Expansion Threshold (THRESHOLD): -72 – -30 dB
Sets the expansion threshold. Expansion will be applied to all
signal levels below the set threshold.
Expansion Ratio (RATIO): 1 – 5
Determines the degree of expansion applied. A setting of 1
produces no expansion, while the maximum setting of 5
produces the greatest degree of expansion (i.e. greatest
attenuation of signals below the threshold).
Initial Delay Time (DELAY): 0.1 – 2300 milliseconds
Determines the time delay between the direct sound and the
beginning of expander operation.

EXCITER PROGRAM

38. EXCITER

This program artificially adds appropriate harmonics to the
input signal, adding luster and effectively bringing "buried"
sounds to the foreground.
HPF FRQ: 500Hz – 16kHz
Determines the range of high harmonics added to the input
sound. The smaller the value, the greater the range of high
harmonics applied.
ENHANCE: 0 – 100%
Sets the level of the harmonics added to the input sound. The
higher the value, the greater the exciter effect.
Exciter/Direct Sound Mix (MIX L VL): 0 – 100%
Sets the mixture or balance between the direct input sound and
the applied harmonics.
DELAY: 0.1 – 1000.0ms
