The V-Series Iris Rotary Panels are user control panels that operate in conjunction with Eclipse HX Digital Matrix Systems. Rotary 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.
