This transmitter is available in the same UHF frequency ranges and is
equipped with the same frequency bank system with factory-preset
frequencies. An advantage of the factory-preset frequencies is that
• a transmission system is ready for immediate use after switch-on,
• several transmission systems can be operated simultaneously on the
preset frequencies without causing intermodulation interference.
The frequency bank system
The diversity receiver is available in 7 UHF frequency ranges with
1,680 receiving frequencies per frequency range:
Range GB:
606 – 648
Range A:
516 – 558
Range G:
566 – 608
Range B:
626 – 668
Range C:
734 – 776
Range D:
780 – 822
Range E:
823 – 865
3
Delivery includes
Each frequency range (A–E, G, GB) offers 26 frequency banks with up to
16 channels each:
Channel 1 – frequency preset
Channel 2 – frequency preset
Frequency bank 1... 20
Channel 16 – frequency preset
Channel 1 – freely selectable frequency
Channel 2 – freely selectable frequency
Frequency bank U1 ... U6
Channel 16 – freely selectable frequency
Each of the channels in the frequency banks “1” to “20” has been factorypreset to a fixed frequency (frequency preset). The factory-preset
frequencies within one frequency bank are intermodulation-free. These
frequencies cannot be changed.
For an overview of the frequency presets, please refer to the supplied
frequency information sheet. Updated versions of the frequency information sheet can be downloaded from the EK 300 IEM G3 product page on our
website at www.sennheiser.com.
The frequency banks “U1” to “U6” allow you to freely select and store
frequencies. It might be that these frequencies are not intermodulationfree (see page 21).

The squelch eliminates annoying noise when the transmitter is switched
off or when there is no longer sufficient transmitter power received by the
receiver.
CAUTION!
Danger of hearing damage!
If you switch the squelch off or adjust the squelch
threshold to a very low value, loud hissing noise can occur
in the receiver. The hissing noise can be loud enough to
cause hearing damage!
Always make sure that the squelch is switched on.
Before adjusting the squelch threshold, set the
volume of the headphone output PHONES to the
minimum (see page 9).
Never change the squelch threshold during a live
transmission.
Adjust the squelch threshold – with the transmitter switched off – to
the lowest possible setting that suppresses hissing noise.
A high squelch threshold reduces the transmission range.
The squelch should only be switched off for servicing purposes. With the
squelch threshold set to “5 dB”, you switch the squelch off by keeping the
DOWN button pressed for 3 seconds.

Synchronizing an SR 300 IEM G3 transmitter with the diversity receiver
Synchronizing an SR 300 IEM G3
transmitter with the diversity receiver
When synchronizing the SR 300 IEM G3 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.
The frequency information sheet can also be downloaded from
the EK 300 IEM G3 product page at www.sennheiser.com.
Synchronization allows you to quickly and easily transfer transmitter and
receiver settings from one device to the other, especially if you want to set
up a multi-channel system. There are two transfer directions:
1. Easy Setup Sync: Transfer from the receiver to one or several transmitters
Once you have performed a frequency preset scan with a receiver, you
use the Easy Setup Sync function to transfer unused frequency presets
from the receiver to the transmitters. In order to set up a multi-channel
system, you use the diversity receiver to transfer the unused channels
from the selected frequency bank one after the other to the transmitters, thus ensuring that all transmitters of a multi-channel system
operate on intermodulation-free frequencies.
2. Sync: Transfer from a transmitter to a receiver
Once you have selected and set the desired receiver settings on the
transmitter (either manually or using the Easy Setup Sync function),
you transfer these settings to a receiver. This configures the receiver
and establishes a transmission link between transmitter and receiver.
When carrying out the Sync function, the transmitter’s current
frequency bank and channel setting as well as the receiver parameters
adjusted via the “Sync Settings” submenu are transferred to the
EK 300 IEM G3 receiver via the infra-red interface.
Setting the transmitters to intermodulation-free
channels (Easy Setup Sync)
Upon delivery, the SR 300 IEM G3 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 intermodulation-free channels and
then transfer these channels to the transmitters. In doing so, no transmission links are established.
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.
With a diversity receiver, perform a frequency preset scan to scan the
frequency banks for unused channels (“Scan New List”, see page 14).
Select a frequency bank with a sufficient number of unused channels
and a channel on this receiver (“Current List”, see page 14).
21
Synchronizing an SR 300 IEM G3 transmitter with the diversity receiver

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.
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:
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:
Start the Sync function by placing the infra-red interface of the first
diversity receiver in front of the infra-red interface 쐏 of the first transmitter while simultaneously pressing the SYNC button 쐋 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.
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.
Using freely selectable receiving frequencies
You can also freely select the receiving frequencies and store these
frequencies in the frequency banks “U1” to “U6”.
It might be that the freely selected frequencies are not intermodulation-free
If you are using frequencies from the frequency banks “U1” to
“U6”, it might be that the receiving frequencies are not intermodulation-free.
Contact your Sennheiser partner who will be pleased to
calculate intermodulation-free frequencies for you (see
www.sennheiser.com).
Set each diversity receiver to the same frequency bank (“U1” to “U6”).
22
Cleaning the diversity receiver
On one of the receivers, select a channel within this frequency bank and
assign this channel a receiving frequency (see page 18).
Synchronize a transmitter with this receiver (see the instruction
manual of the transmitter).
OR:
Manually set the transmitter to the same frequency bank and channel
that you set on the receiver.
Repeat for the remaining transmitters and receivers as described
above.
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.
Keep all liquids away from the diversity receiver.
Do not use any solvents or cleansing agents.
Use a cloth to clean the diversity receiver from time to time.
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 (see page 17).
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
