Intuitive and easy to operate, KeyLinX features 10 (ten) laser-etched hard key buttons for basic source selection (4 sources) and transport control.  Attractive blue LEDs provide the backlighting on these buttons, which change to Amber when a source is selected.  Choose from high or low backlighting.  Green LEDs easily show the volume level of the source equipment so that at a glance, the user can determine the current volume level for the music playing in that room. Programming the operation of the hard key buttons is extremely easy thanks to the PC-based DigiLinX Dealer Setup program.
