Synchronizing a transmitter with the diversity receiver
Synchronizing a transmitter with the
diversity receiver
When synchronizing the SR 2000 IEM or SR 2050 IEM transmitter
with a diversity receiver, please observe the following:
왘 Only use a transmitter and a diversity receiver from the same
frequency range (see the type plate on the transmitter and the
diversity receiver).
왘 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.
왘 Make sure that the desired frequencies are approved and legal
in your country and, if necessary, apply for an operating
license.
Setting the transmitters to intermodulation-free
channels (Easy Setup Sync)
Upon delivery, the SR 2000 IEM or SR 2050 IEM transmitter and the diversity receiver are synchronized with each other. If, however, you cannot
establish a transmission link between transmitter and diversity receiver,
you first have to use the diversity receiver to determine intermodulationfree channels and then transfer these channels to the transmitters. In
doing so, no transmission links are established.
왘 On all transmitters, call up the “Easy Setup” menu item.
“Easy Setup Sync” appears on the display panels of the transmitters.
The RF signals of the transmitters are deactivated. The transmitters
await the transfer of a channel and a frequency bank via their infra-red
interfaces.
왘 With a diversity receiver, perform a frequency preset scan to scan the
frequency banks for unused channels (“Scan New List”).
왘 Select a frequency bank with a sufficient number of unused channels
and a channel on this receiver (“Current List”).
왘 Start the Easy Setup Sync function by placing the infra-red interface of
this diversity receiver in front of the infra-red interfaces of all transmitters, one after the other.
The diversity receiver transfers an unused channel from the selected
frequency bank to the first transmitter and the next unused channel to
the second transmitter and so on. As soon as a transfer is completed,
the display panel of the transmitter displays the numbers of the transferred frequency bank and channel.
20
Cleaning the diversity receiver
Synchronizing transmitters with diversity receivers
(Sync)
In a second step, you transfer the frequency bank and channel settings
from the transmitters to other diversity receivers (synchronization) and
thus establish the transmission links.
If you want to carry out synchronization at a later time:
왘 Press the jog dial on the transmitter.
The frequency bank and the channel are stored. The transmitter’s
RF signal is activated again. You can synchronize this transmitter with
a diversity receiver at any time (see the instruction manual of the
transmitter).
To carry out synchronization immediately:
왘 Start the synchronization function by placing the infra-red interface of
the first diversity receiver in front of the infra-red interface of the first
transmitter while simultaneously pressing the SYNC button on the
transmitter.
The diversity receiver is set to the same frequency bank and channel as
the transmitter. The transmitter’s RF signal is activated again. A transmission link is established between the first transmitter and the first
diversity receiver.
왘 Synchronize each of the remaining transmitters with one of the
remaining diversity receivers.
Your multi-channel monitoring system is now ready for operation.
Instead of synchronizing, you can manually set the transmitters to the
same frequency bank and channel that you set on the corresponding
diversity receivers.
Cleaning the diversity receiver
CAUTION!
Liquids can damage the electronics of the diversity
receiver!
Liquids entering the housing of the device can cause a
short-circuit and damage the electronics.
왘 Keep all liquids away from the diversity receiver.
왘 Do not use any solvents or cleansing agents.
왘 Use a cloth to clean the diversity receiver from time to time.

Recommendations and tips
Recommendations and tips
... for the diversity receiver
• Make sure that the antenna and the earphones cable do not cross.
• For best results, make sure that the transmitter sensitivity is correctly
adjusted.
... for optimum reception
• Transmission range depends to a large extent on location and can vary
from about 10 m to about 150 m. There should be a “free line of sight”
between transmitting and receiving antennas.
• To avoid overloading the receiver, observe a minimum distance of 5 m
between transmitting and receiving antennas.
... for multi-channel operation
• When operating a multi-channel system, you should only use the channels within one frequency bank. Each of the frequency banks “1” to
“20” accommodates factory-preset frequencies which are intermodulation-free.
• The frequency banks “U1” to “U6” allow you to freely select and store
receiving frequencies.
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
