Additional information
The channel bank system
The 2015 System is available in five UHF frequency ranges with 1440
transmission/receiving frequencies per frequency range. Please note:
Frequency usage is different for each country. Your Sennheiser agent will
have all the necessary details on the available legal frequencies for your area.
Range A: 518 to 554 MHz Range D: 786 to 822 MHz
Range B: 626 to 662 MHz Range E: 830 to 866 MHz
Range C: 740 to 776 MHz
Transmitter and receiver have nine channel banks with up to 20 switchable
channels each.
Each of the channels in the channel banks “1” to “8” has been factory-preset
to a transmission/receiving frequency (see enclosed frequency table). These
frequencies cannot be changed but have been preset so that e.g. country-
specific regulations on frequency usage are taken into account. The channel
bank “U” (user bank) allows yo u to store your selection out of 1440
transmission/receiving frequencies that are freely selectable within the preset
frequency range.
An advantage of the factory-preset frequencies is that
y the system is ready for immediate use after switch-on,
y several systems can be operated simultaneously on the preset channels of
a channel bank without causing intermodulation interference.
