Additional information
The channel bank system
The 2015 System is available in three UHF frequency ranges with 1,440 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 B: 626 to 662 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 are preset and cannot be changed as country-
specific regulations on frequency usage are taken into account. The channel bank “U” (user bank) allows
you to store your selection out of 1,440 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.
