Section 7 — Effect Parameters TS-12 Musician’s Manual
4
BANDWIDTH Range: 00 to 99
The high-frequency bandwidth acts as a low pass filter on the signal going into the reverb,
controlling the amount of high frequencies that will pass into the effect. The higher the setting,
the more high frequencies are allowed to pass. This functions like a tone control on a guitar.
LF DECAY TIME Range: -99 to +99
Functions as a tone control and boosts (when set to a positive value) or cuts (when set to a
negative value) the rate at which low frequencies will decay.
DEFINITION Range: 00 to 99
Controls the rate at which echo density is increased with time. Setting this parameter too high
can cause the echo density to build at a rate which exceeds the decay rate. A general rule of
thumb is this: DEFINITION should not exceed the LF DECAY TIME added to the DECAY TIME.
DIFFUSION-1 Range: 00 to 99
Smears the input signal transients, to diffuse and smooth the sound. Lower values will cause
impulse sounds to appear as a series of discrete echoes, while higher values tend to increase the
smear (smoother sounding with fewer discrete echoes). We recommend settings of 50 for
starters.
DIFFUSION-2 Range: 00 to 99
This parameter, similar to and in series with DIFFUSION-1, performs the same way but controls
lower-frequency ranges. Experiment with different levels between the diffuser parameters to
find the settings that are right for your source.
REFL-1 TIME Range: 0000 to 0120 msec
Controls the delay time for the first pre-echo. Pre-echoes are the first sounds that have been
reflected back from the walls or reflective “live” surfaces. Higher values delay the diffused signal
more.
REFL-1 LEVEL Range: 00 to 99
Controls the level of the first pre-echo. This pre-level controls the echo send to the Definition.
REFL-1 SEND Range: 00 to 99
Controls the level of the first pre-echo, with the echo routed directly to the output.
REFL-2 TIME Range: 0000 to 0120 msec
Controls the delay time for the second pre-echo.
REFL-2 LEVEL Range: 00 to 99
Controls the level of the second pre-echo. As a signal continues to bounce off the different
reflective surfaces (walls), it decreases in volume. Set this parameter to a lower value than REFL-
1 LEVEL to create a natural sounding echo.
REF-2 SEND Range: 00 to 99
Controls the level of the second pre-echo, with the echo routed directly to the output.
DETUNE - RATE Range: 00 to 99
Controls the LFO rate of detuning introduced into the reverberation decay. Detuning creates a
slight oscillating pitch shift into the decay, giving it a more natural sound by breaking up
resonant nodes.
