The L 2021-40 19" charger rack has been specially designed for stationary applications. It holds up to 40 receivers that will automatically quick-charge. Truly impressive feature of the charging case is the Copy button. All you need do is to set one receiver to the correct channel, press this button just once, and all of the other receivers in the case will immediately be set to the same channel. At the same time, the L 2021-40 serves as an ethernet LAN port to allow pre-selecting the active channel for each receiver on a central PC. Up to 125 charger racks with up to 5000 receivers can be programmed via CC 2021 control software. CC 2021 offers simple presets to select and confirm channels for all receivers with just one click. Users and service staff can easily monitor which receivers at which station have been prepared for any given language or program. Configuration problems are a thing of the past!
