The four SELECT keys, the LEVEL up/down keys as well as the ON (-muteed-) key can be separately programmed to perform the desired function. The assignment of functions is done from the Altair 3cMAP control program. The keys can function as momentary or latching action depending on the assigned action. Each key incorporates an LED indicator to show its activity or show options, ends of travel, etc.

Each SELECT key includes space for a small reminder label.

A pair of up/down keys is available for level or parameter adjustment.

A key for on/off (-muteed-) of the input, output or routing allows the temporary reduction of the room level without losing the usual setting.

Each key function is defined as Button 1, Button 2, Button 3, Button 4, Level and On in the REMOTE CONTROLS window of the 3cMAP program.

NOTE: The level change operations act with 3 speeds to allow a more rational adjustment, the first touches being more precise becoming less precise to speed up changes.
