Audio Indicators

A simple meter bridge above the display holds three LEDs per channel. The lowest LED indicates that a signal is present, 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 offending parameter settings. This should not occur with factory Programs, unless they have been edited.

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, stored Program or Register will be loaded and the display will show a red banner that says "LISTENING TO ORIGINAL PRESET". 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 normal 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 setting you want. Each press of these buttons changes the parameter by its smallest possible increment.
