TSL (Treble Slope)
TSL defines the ratio of the high-frequency compres-
sor. A LARC value of 128 equals a 2:1 compression
ratio.
TBR (Treble rotate - threshold)
TBR control determines the point at which compres-
sion starts to occur.
TBM (Treble Maximum Gain)
TBM controls the amount of gain introduced below the
Rotate value. ie: If Rotate is set to -14, and gain is set
at 10, when signals go below -14dB (average) then the
signal will be boosted by 10dB.
EXP (Expansion Slope)
EXP determines the amount of expansion after the
distortion DSP.
SUS (Sustain)
SUS works in conjunction with the expander to provide
additional sustain throughout dynamic transitions.
DHP (High Pass on Distortion)
DHP controls a 6dB/octave filter which is conceptually
placed after the distortion module but before the Ex-
pander.

DLY (Front Delay)
DLY determines the amount audio delay before the
compressor modules. This effectively allows the 480L
to perform a "look ahead" function to the compressors.
LSL (Low frequency Compression Ratio)
LSL defines the ratio of the low-frequency compressor.
A LARC value of 128 equals a 2:1 compression ratio.
LFR (Low Frequency Rotation Point)
LFR d determines the point at which low-frequency
compression starts to occur.
LMG (Low Frequency Maximum Gain)
LMG controls the amount of low-frequency gain intro-
duced below the Rotate value. ie: If Rotate is set to -
24, and gain is set at 6, when signals go below -24dB
(average) then the signal will be boosted by as much as
6dB.
ATC (Attack Time Constant)
ATC sets the attack time.
RTC (Release Time Constant)
Sets the release time.

GATE (Noise Gate)
GATE sets a value at which the noise gate starts to
occur. Units are described in dB below 0. These values
should, typically, be set very high.
