AUDIO INDICATORS
A simple meter bridge above the display holds three LEDs
per channel. The lowest LED indicates that a signal is pre-
sent, defined as a level of –60 dBFS or more. When levels
exceed –6 dBFS, the middle LED lights as a warning of
reduced headroom. Above –0.5 dBFS, the top LED lights
to indicate imminent overload.
If all eight overload LEDs are illuminated, an overflow has
occurred in the DSP accumulator. This can happen even
with modest signal levels if the delay/reverb feedback
coefficients (which are set by the algorithm parameters)
combine to create some path with a gain greater than
unity. Generally, you should mute the outputs (MUTE
MACH or MUTE ALL), and then find and correct the offend-
ing parameter settings. This should not occur with factory
Programs, unless they have been edited.
Note:
M o re comprehensive metering can be done
using the meter screen described in Section 3 of
this manual.
THE LEXICON BUTTON
The Lexicon button is used for quick A/B comparisons
between the current version of a Program or Register,
including your edits, and the effect as originally loaded.
When the button is held down, the original, store d
Program or Register will be loaded and the display will
show a red banner that says "LISTENING TO ORIGINAL PRE-
SET". When the button is released, your last Edit state will
be reloaded and the red banner will disappear.
FINE ADJUST
It is difficult to set parameters with large value ranges to
precise values with the faders. For example, the fader
range for some delays must allow for the fact that delays
of 1,000 milliseconds are not uncommon, yet the value
often needs to be set within a few milliseconds or even
samples.
To make such fine adjustments, set the faders to the
approximate values you want, then press the FINE ADJ
button. When this button is pressed, the faders all move to
the center of their travel, but their settings do not change.
The faders then operate in a vernier mode, with a limited
adjustment range and far fewer steps per inch of travel.
This makes it easy to set the parameter to the exact value
you want.
Pressing FINE ADJ a second time returns the system to nor-
mal operation and the faders return to their appropriate
full-range positions. The display warns when the system is in
Fine Adjust mode, but the centering of all faders is a more
obvious tip-off.
For fine adjustments of a single parameter while in Edit
Algorithm mode, simply touch the appropriate fader, then
use the Increment/Decrement (+/-) buttons to get the set-
ting you want. Each press of these buttons changes the
parameter by its smallest possible increment.
