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 bank s 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 you 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.
