The Sonifex LD-40F2MCL-PHN is a flush mounting, twin illuminated sign with 2 x 20cm signs displaying the words ‘MIC LIVE’ and ‘PHONE’. There are 4 display modes, and because the signs are illuminated using RGB LEDs, they can be one of 9 colours. The display mode and colour are both controllable via the optional LD-RPC remote control.
