CONTROLS (continued)
FX Adjust
FX Adjust controls the level of the processed (wet) signal before it
is mixed with the dry signal (if any) and sent to the audio outputs.
The range of this parameter is +12dB to -73dB, and Off (wet
output muted.) FX Adjust is inactive when the PCM 81 is in Bypass
mode, so it is a good idea to compare the levels with Bypass on and
off while editing this parameter. Adjust it until the audio level
sounds the same with bypass on and off.
InLvl L&R, InPan L&R
InLvl L and InLvl R control the level and phase of the unprocessed
dry signal into the effects. The range of these parameters is from
Full (0dB) Phase Normal, to -85dB Phase Normal, Off, -85dB Phase
Inverted to Full (0dB) Phase Inverted.
InPan L and InPan R control the location of the left and right input
audio as a stereo image to the effect's audio input. Unmodified
stereo imaging to the effects can be achieved by setting InPan L
hard left (50L) and InPan R hard right (50R). Changing InPanL to
any other value (49L to 50R), takes the left audio input and
presents it as a panned source to the effect's left and right input.
Changing InPan R to any value other than 50R, does the same for
the right audio input.
High Cut
High Cut sets the high frequency cutoff of a low-pass filter. This
parameter affects both channels.
Voice Dif
This parameter is available in all of the 4-Voice Algorithms, and in
Glide>Hall. It controls the density of echoes in the delay voices,
independently of Reverb diffusion. High levels of diffusion thicken,
or smear, the echoes. This is most noticeable on material with sharp
transients.
FX Mix
FX Mix controls the balance of reverb and non-reverb effects.
(Non-reverb effects are those processed as "voices" controlled by
level, delay and feedback parameters generally found in rows 3-7.)
The range of this control is 0 to 100%.
FX Width
FX Width can be thought of as an extension of typical mono to
stereo imaging controls. The range of this parameter is -360 to
+360, in single digit increments. Values of -360, 0, or +360 cause
the effect's audio output to be mono. Values of -315 and +45 cause
the output to be normal left/right stereo. Values of -45 and +315
cause "swapped", or right/left stereo.
The large and duplicated range of this parameter allows smooth
glides from any Left/Right Mix, Phase, Mono/Stereo image point to
any other. These are on the output of the FX Mix. Of particular
interest are: 0 MONO, 45 STEREO, and 90 L–R, R–L (surround
channel). This parameter can be changed in real-time for
fascinating spatial effects.
