Synchronizing a transmitter with the diversity receiver
Synchronizing a transmitter with the
diversity receiver
Upon delivery, transmitter and diversity receiver are synchronized with
each other. If, however, you cannot establish a transmission link between
transmitter and diversity receiver, you have to synchronize the channels of
the devices:
̈ Deactivate the RF signal on all transmitters (see the instruction manual
of the transmitter).
This prevents that, during the frequency scan, the channels used by
switched-on transmitters are displayed as “used”.
̈ With a diversity receiver, perform a frequency preset scan to scan the
frequency banks for unused channels (“Scan New List”, see page 15).
̈ Select a frequency bank and a channel on this diversity receiver
(“Current List”, see page 15).
If you want to set up a multi-channel system, select a frequency bank
with a sufficient number of unused channels for all planned transmis-
sion links.
̈ Synchronize a transmitter with the diversity receiver
(see page 14).
The receiver’s frequency, name and pilot tone setting are transferred to
the transmitter.
OR:
̈ Manually set the transmitter to the same frequency bank and channel
that you set on the receiver.
̈ Activate the RF signal on this transmitter.
The transmission link is established.
If you want to set up a multi-channel system:
̈ Repeat the following 4 steps for each additional transmission link:
Perform a frequency preset scan with the next diversity receiver.
Select a channel from the same frequency bank as with the first
diversity receiver.
Synchronize a transmitter with the diversity receiver.
Activate the RF signal on the transmitter.
Using freely selectable receiving frequencies
You can also freely select the receiving frequencies and store these
frequencies in the frequency bank “U”.
̈ Set each diversity receiver to the frequency bank “U”.
When synchronizing a transmitter with a diversity receiver, please
observe the following:
̈ Only use a transmitter and a diversity receiver from the same
frequency range (see the type plates on the transmitter and
the diversity receiver).
̈ Make sure that the desired frequencies are listed in the
enclosed frequency information sheet.
You can also contact your Sennheiser partner who will be
pleased to calculate intermodulation-free frequencies for you.
̈ Make sure that the desired frequencies are approved and legal
in your country and, if necessary, apply for an operating
license.
It might be that the freely selected frequencies are not inter-
modulation-free
If you use frequencies from the frequency bank “U”, it might be
that the frequencies are not intermodulation-free.
̈ Contact your Sennheiser partner who will be pleased to
calculate intermodulation-free frequencies for you (see
www.sennheiser.com).
