4: THE PROGRAMS & PARAMETERS
PARAMETERS PROVIDED
FOR ALL PROGRAMS
LEVEL PARAMETERS (Accessed via LEVEL key)
Effect/Direct Signal Balance (BALANCE): 0 – 100%
This parameter adjusts the balance between the direct sound
and effect signals. At 100% only the effect sound is delivered
from the SPX1000 outputs, while at 0% only the direct sound
is output. At a setting of 50%, the direct and effect sounds are
output in approximately equal proportions.
Effect Output Level (OUT LVL): 0 – 200%
This parameter sets the overall output level of the effect
program. This is particularly handy for matching levels
between different effects.
2-CHANNEL PROGRAM (PROGRAMS 31 – 35) LEVEL
PARAMETERS
The level parameters available for the 2-channel programs
(programs 3 1 – 35) are the same as those for the other
programs, except that separate parameters are provided for the
left and right channels.
BALANCE 1 = 1 (Left)-channel Balance
BALANCE 2 = 2 (Right)-channel Balance
OUT LVL 1 = 1 (Left)-channel Output Level
OUT LVL 2 = 2 (Right)-channel Output Level
EQ PARAMETERS (Accessed via EQ key)
When the EQ key is pressed, you are presented with three
choices: “OFF” (the default setting), “EQ” (2-band parametric
equalizer mode), or “D.FLT” (Dynamic Filter mode). Use the
parameter and keys to select the desired mode of
operation. The EQ mode provides 2-band parametric
equalization, while the Dynamic Filter mode provides a filter
which can be automatically swept across a specified frequency
range by the SPX1000’s internal low frequency oscillator or
the level of the input signal.
PARAMETERS AVAILABLE IN THE “EQ"
MODE
Low EQ Peaking or Shelving Response (LOW EQ.):
PEAK, SHLV
High EQ Peaking or Shelving Response (HIGH EQ):
PEAK, SHLV
These parameters determine whether the corresponding band
has a peaking or shelving filter response.
Low EQ Frequency (LOW FRQ): 32 Hz – 2.2 kHz
High EQ Frequency (HIGH FRQ): 500 Hz – 16 kHz
These parameters determine the center frequency for
equalization in the corresponding band. In the shelving mode,
these parameters represent the turn over frequency rather than
the center frequencies.
Low EQ Gain (LOW GAIN): -15 – + 15 dB
High EQ Gain (HIGH GAIN): -15 – + 15 dB
These parameters determine the amount of boost or cut
applied to the corresponding EQ band.
Low EQ Bandwidth (LOW Q): 0.1 – 5.0 (PEAK mode
only)
High EQ Bandwidth (HI Q): 0.1 – 5.0 (PEAK mode
only)
These parameters determine the bandwidth of the
corresponding EQ band. A setting of 5.0 produces the
narrowest bandwidth (sharpest response), and the minimum
setting of 0.1 produces the widest bandwidth (broadest
response). Note that the “Q” parameters for the low and high
bands only function when the corresponding band is set to the
PEAK mode.
PARAMETERS AVAILABLE IN THE “D.FLT”
MODE
Control Type (CTL TYPE): LFO, LEVEL
Determines whether the sweep of the dynamic filter is
controlled by the SPX1000’s LFO (Low Frequency Oscillator)
or the level of the input signal to analog trigger.
