Multi-channel operation
Combined with Sennheiser 3000 and 5000 series transmitters, the
receivers can form transmission links that are suitable for multi-channel
operation.
Before putting the transmission links into operation, we recommend that
you perform a scan in order to find a frequency bank with a sufficient
number of free channels:
̈
Switch all transmitters off.
̈
Use a receiver to scan all frequency banks for free channels (see
“Scanning the frequency banks for interference-free channels” on
page 33).
̈
Select a frequency bank with a sufficient number of free channels (see
“Selecting a frequency bank and a channel” on page 28).
̈
Set each transmitter/receiver pair in your multi-channel system to a
different free channel within this frequency bank.

CAUTION!
Risk of reception interference!
If – within the receiver’s frequency range – transmitters
transmit on channels from different frequency banks, reception
can be subject to interference and inter-modulation. Only the
factory-preset frequencies within the frequency banks “1” to
“6” are interference and inter-modulation free.
̈
Set all transmitters of a multi-channel system to different
channels within the same frequency bank.
