The V-Series Rotary Panels are user control key-panels that operate in conjunction with the Eclipse and Eclipse HX Digital Matrix Systems. Rotary key-panels feature one display window per “key” and have two individual controls for the same display; a rotary encoder for level control with a pushbutton switch feature for Listen (push on/off) and separate pushbutton for Talk (push on/off). Each control offers discrete LED tally indication; red for Talk and green for Listen.
