PROGRAMMABLE CONTROL KNOBS
It’s important to note that all top control panel knobs except Master Volume (H) are, as described above,
“programmable.” That means that when a preset is rst selected, the physical position of a top control panel
knob may not indicate the actual setting contained in that preset (the actual setting appears in the display
window). Only the Master Volume control is not programmable—its physical position always indicates actual
overall volume. Once a programmable top control panel knob is turned, however, it and its digital counter-
part within a preset become synchronized to the same value, as illustrated here:
Also note that an adjusted control knob setting can be saved in a new preset, or the original preset can be
overridden with the adjusted control knob setting. If the adjusted setting is not saved, the preset will revert
to its pre-programmed control knob settings when returning to the preset after leaving it, or when turning
the amplier o and back on again (see further info under “Editing and Saving Presets” pages 5-6).
