The UP radio receives DAB, DAB+, and FM radio stations. It features a rear Aux input for connecting another audio source, such as the Bluetooth receiver BTR 55 MK2. Up to 9 DAB and 9 FM stations can be stored. The DAB/FM radio UP fits into all common switch programs with a 55x55 mm central plate. The power of the integrated stereo amplifier has more than doubled compared to the proven predecessor model, the RDS radio. Two speakers or the further improved UP speaker KEL 55 can be connected to it. Operation is incredibly easy with just two buttons and a rotary control. The menu allows for many additional functions to be set, such as alarm, sleep, display brightness, and maximum volume. For hotel use, scanning for radio stations can be disabled to prevent accidental adjustments. The DAB/FM radio can even be controlled via the optional remote control and comes with a throw antenna that can be pushed into the conduit. The antenna of the DAB+ UP radio is shielded more or less depending on the wall material, which can affect reception. Therefore, check before installation whether FM/DAB+ radio stations can be received at the planned installation location.
