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.

Both the KL101 and KL201 products feature a built-in IR window for the pass-through of IR to a local source connected to the Audio Port (optional).

The IRLinX connectors on KL101 and KL201 accommodate the use of the IRLinX IR receiver (sold separately) for enhanced IR control of the system.  IRLinX enables IR Control of the DigiLinX system, including volume up and down and source selection, as well as allowing for the pass-through of IR codes from a source remote, via an Audio Port AP500, to a local source when connected.  Additionally, IRLinX can pass through IR from a universal remote to the currently selected legacy source, allowing for easy one-remote control of the entire system.

The KeyLinX KL201 has several features not found in a KL101: 
• a built-in microphone for IP Intercom applications like room-to-room intercom and
  whole house paging
• a Do-Not-Disturb (DND) LED and feature, for those times that a user does not wish to be     
  disturbed by intercom (*requires IP Intercom to be enabled)
• a message indicator LED for a future room messaging application
• a monitor LED for room monitoring (*requires IP Intercom to be enabled).
