Multi-band Dynamics Processor (PRESET bank)This effect splits the signal into three frequency bands, and individually controls the dynamic range of each band. It lets you
use three types of processor — a compressor, expander, and limiter — in combination. The signal is sent through the
expander, compressor, and limiter in that order.
Compressor: CMP.THRE, CMP.RAT, CMP.ATK, CMP.REL, CMP.KNEE, CMP.BYP
Expander: EXP.THRE, EXP.RAT, EXP.REL, EXP.BYP
Limiter: LIM.THRE, LIM.ATK, LIM.REL, LIM.BYP, LIM.KNEE
Applicable to Compressor, Expander, and Limiter: PRESENCE, LOOKUP
Filter/equalizer: LOW GAIN, MID GAIN, HI. GAIN, L-M XOVR, M-H XOVR, SLOPE
Output level: CEILING, MIX BAL., SOLO LOW, SOLO MID, SOLO HI
Parameter details
■Basic parameters
Parameter name Range Explanation
LOW GAIN –96.0—+12.0 dB Low range gain. Raising this value will boost the low-frequency range.
MID GAIN –96.0—+12.0 dB Mid range gain. Raising this value will boost the mid-frequency range.
HI. GAIN –96.0—+12.0 dB High range gain. Raising this value will boost the high-frequency range.
PRESENCE –10—+10
This setting varies the effect separately for each range. Positive (+) settings of this value will lower the
high-frequency threshold level and raise the low-frequency. Negative (–) settings will raise the high-fre-
quency and lower the low-frequency. With a setting of 0, all ranges will have the same threshold level.
CMP.THRE –24.0—0.0 dB Compressor threshold level. When the level of the input signal (original sound) exceeds this level,
the portion above this level will be compressed by the CMP.RAT.
CMP.RAT 1:1—20:1 Compression ratio. When the input signal level exceeds CMP.THRE, the portion of the signal
above that level will be compressed by this ratio.
CMP.ATK 0—120 ms
Compressor attack time. This is the time from when the input signal level exceeds CMP.THRE
until the maximum compression is reached.
You can use this when you want to retain the attacks of the original signal.
CMP.REL*a
*a. The range of this parameter depends on the sampling frequency at which the SPX2000 is operating.
44.1 kHz: 6 ms—46.0 s
48 kHz: 5 ms—42.3 s
88.2 kHz: 3 ms—23.0 s
96 kHz: 3 ms—21.1 s
Compressor release time. The original signal level is not resumed the instant the input signal falls
below CMP.THRE; the signal will gradually return to its original level over the duration of this
value.
CEILING –6.0—0.0 dB, OFF Upper limit of the output level. Signals that exceed this value will be restricted to this value. If you
select OFF, this restriction will be defeated.
EXP.THRE –54.0—–24.0 dB Expander threshold level. When the input signal falls below this level, it will be compressed by the
EXP.RATIO.
EXP.RAT 1:1—∞:1
Expander ratio. When the input signal level falls below EXP.THRE, it will be compressed by this ratio.
EXP.REL*a
44.1 kHz: 6 ms—46.0 s
48 kHz: 5 ms—42.3 s
88.2 kHz: 3 ms—23.0 s
96 kHz: 3 ms—21.1 s
Expander release time. This is the time from when the input signal falls below EXP.THRE until the
maximum expander effect is reached.
LIM.THRE –12.0—0.0 dB Limiter threshold level. When the input signal (original sound) exceeds this level, it will be
restricted to this value.
LIM.ATK 0—120 ms
Limiter attack time. This is the time from when the input signal exceeds LIM.THRE until maxi-
mum limiting is reached.
You can use this when you want to retain the attacks of the original signal.
LIM.REL*a
44.1 kHz: 6 ms—46.0 s
48 kHz: 5 ms—42.3 s
88.2 kHz: 3 ms—23.0 s
96 kHz: 3 ms—21.1 s
Limiter release time. This is the time from when the input signal falls below LIM.THRE until limit-
ing is removed.
