tions can damage your hearing. At higher volumes, the duration must be  
shortened in order to prevent hearing damage. The following are sure  
signs that you have been subjected to excessive noise for too long a time:  
You can hear ringing or whistling sounds in your ears.  
You have the impression (even for a short time only) that you can no  
longer hear high notes.

Preparing the receiver for use  
Recommendations for optimum reception  
To ensure optimum reception even under difficult conditions, we  
recommend connecting remote antennas and, if necessary, using  
antenna splitters (see “Accessories and spare parts” on page 52).  
When rack-mounting the receiver, you can mount the supplied  
antennas to the front of the rack by using an antenna front mount  
kit. When mounting more than one receiver into a rack, you should  
use remote antennas.  
If you want to mount the receiver into a 19” rack:  
̈ Read the corresponding chapter on page 14.  
If you want to set up the receiver on a flat surface:  
̈ Read the next chapter.  
Setting up the receiver on a flat surface  
CAUTION!  
Risk of staining of furniture surfaces!  
Some furniture surfaces have been treated with varnish, polish or  
synthetics which might cause stains when they come into contact with  
other synthetics. Despite a thorough testing of the synthetics used by us,  
we cannot rule out the possibility of staining.  
̈ Do not place the receiver on delicate surfaces.  
Mounting the rack  
mount “ears”  
The rack mount “ears” are designed to help protect the operating  
elements from damage or deformation, e.g. if the receiver is  
dropped. Therefore, fasten the rack mount “ears”, even if you do  
not want to rack mount your receiver.  
To fasten the rack mount “ears” ƿ:  
̈ Unscrew and remove the two recessed head screws (M4x8) on each  
side of the receiver (see left-hand diagram).

Putting the receiver into operation  
Mounting the receiver into a 19” rack  
Do not fit the device feet when mounting the receiver into a  
19” rack.  
CAUTION!  
Risks when rack mounting the receiver!  
When installing the device in a closed or multi-rack assembly, please  
consider that, during operation, the ambient temperature, the mechanical  
loading and the electrical potentials will be different from those of devices  
which are not mounted into a rack.  
̈ Make sure that the ambient temperature within the rack does not  
exceed the permissible temperature limit specified in the specifications  
(see page 54).  
̈ Ensure sufficient ventilation; if necessary, provide additional ventila-  
tion.  
̈ Make sure that the mechanical loading of the rack is even.  
̈ When connecting to the power supply, observe the information indi-  
cated on the type plate. Avoid circuit overloading. If necessary, provide  
overcurrent protection.  
̈ When rack mounting, please note that intrinsically harmless leakage  
currents of the individual mains units may accumulate, thereby  
exceeding the allowable limit value. As a remedy, ground the rack via an  
additional ground connection.  
Rack mounting ̈ Secure the rack mount “ears” ƿ of the supplied GA 3 rack adapter to  
one receiver the receiver as described on page 12.  
̈ Secure the blanking plate

Adjustment tips and functions  
Adjustment tips and functions  
The operating menu allows you to make settings for your receiver and your  
transmitters. The “Soundcheck” standard display provides an additional  
function and can be called up by turning the jog dial, without having to get  
into the operating menu.  
Doing a soundcheck  
By doing a soundcheck, you can check the reception area for field strength  
gaps (“dropouts”) which cannot be compensated for by the receiver’s  
diversity circuitry.  
The “Soundcheck” standard display must not be activated until  
later because otherwise the recording will give wrong results.  
̈ If necessary, change from the “Soundcheck” standard display to one of  
the other standard displays of your receiver.

The squelch eliminates annoying noise when the transmitter is switched  
off. It also suppresses sudden noise when there is no longer sufficient  
transmitter power received by the receiver.  
̈ Adjust the squelch threshold – with the transmitter switched off – to  
the lowest possible setting that suppresses hissing noise.  
If you adjust the squelch threshold to a high value, the transmis-  
sion range will be reduced under adverse RF reception conditions.  
CAUTION!  
Danger of hearing damage and material 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 or overload the loudspeakers of  
your system!  
̈ Always make sure that the squelch is switched on (see below).  
̈ Before adjusting the squelch threshold, set the volume of the head-  
phone output (see page 21) and the audio output level (“AF Out”, see  
page 36) to the minimum.  
̈ Never change the squelch threshold during a live transmission.

Synchronizing transmitters with receivers  
Synchronizing transmitters with  
receivers  
When synchronizing a transmitter with a receiver, please observe the  
following:  
̈ Only use a transmitter and a receiver from the same frequency  
range (see the type plate on the transmitter and the receiver).  
̈ Make sure that the desired frequencies are listed in the enclosed  
frequency information sheet.  
̈ Make sure that the desired frequencies are approved and legal  
in your country and, if necessary, apply for an operating license.  
Synchronizing a transmitter with the receiver –  
individual operation  
Upon delivery, transmitter and receiver are synchronized with each other.  
If, however, you cannot establish a transmission link between transmitter  
and receiver, you have to synchronize the channels of the devices:  
̈ With the receiver, perform a frequency preset scan to scan the  
frequency banks for unused channels (“Scan New List”, see page 34).  
Then “Sync” appears on the display panel of the receiver.

Synchronizing transmitters with receivers  
Synchronizing transmitters with receivers –  
multi-channel operation  
In order to ensure an intermodulation-free transmission, use the  
same frequency bank for all transmission links.  
Network operation Combined with ew 300 G3 transmitters, ew 300 G3 receivers can form  
transmission links that can be used in multi-channel systems.  
In multi-channel operation, the receivers are remote controlled via a PC  
running the “Wireless Systems Manager” (WSM) software.  
For further information on downloading the software, visit the ew G3  
Advantages of controlling the receivers via the “Wireless Systems  
Manager” (WSM) software:  
• Detailed overview of all receiving channels  
WSM  
• Remote control of all receivers in the network  
• Combination of receivers of different frequency ranges  
(see page 6).  
̈ Connect the receivers in a network (see page 18).  
̈ Launch the “Wireless Systems Manager” (WSM) software.  
̈ To scan for unused receiving frequencies and to configure the receivers,  
proceed as described in the instruction manual of the “Wireless  
Systems Manager” (WSM) software.  
̈ Set the corresponding transmitter to the selected frequency bank and  
to the selected channel either by synchronizing the transmitter with  
the receiver (see page 22) or by setting the frequency bank and the  
channel manually (see the instruction manual of the transmitter).  
Your multi-channel system is now set up.  
Operation If you want to set up a multi-channel system without using the WSM,  
without network proceed as follows:  
̈ Switch off all transmitters of your system that are to be automatically  
configured.  
Channels used by switched-on transmitters are displayed as “used”.

̈ Repeat for the remaining transmitter and receiver pairs as described  
above. Leave those transmitters switched on that are already linked to  
a receiver.  
Your multi-channel system is now set up.  
Alternatively, you can set the channel on the transmitter manually:  
̈ Make sure that you set the transmitter to the same frequency bank and  
the same channel as the receiver.  
For information on the setting options of the transmitter, refer to the  
instruction manual of the transmitter.  
You can also freely select the receiving frequencies and store these  
frequencies in the frequency banks “U1” to “U6”.  
If you are using frequencies from the frequency banks “U1” to

To ensure that the desired frequencies are intermodulation-free:  
̈ Contact your Sennheiser partner (see www.sennheiser.com).  
If you want to use the frequency banks “U1” to “U6”:  
̈ Make sure to use receivers from the same frequency range (see page 6

Recommendations and tips  
Recommendations and tips  
... 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.  
If, with the EM 300 G3 receiver, reception conditions are unfavourable,  
you should use two remote antennas which are connected via  
antenna cable.  
To avoid overloading the receiver, observe a minimum distance of 5 m  
between transmitting and receiving antennas.  
Observe a minimum distance of 50 cm between receiving antennas  
and metal objects (such as cross members or reinforced-concrete  
walls). Align the antennas upwards in a V-shape.  
... for multi-channel operation  
Each of the frequency banks “1” to “20” accommodates factory-  
preset receiving frequencies which are intermodulation-free. For  
possible frequency combinations, please refer to the supplied  
frequency information sheet.  
The channels in the frequency banks “U1” to “U6” can be assigned  
freely selectable frequencies (see page 38).  
When using several transmitters simultaneously, interference can be  
avoided by maintaining a minimum distance of 20 cm between two  
transmitters.  
Use accessories recommended by Sennheiser for multi-channel appli-  
cations (see page 52).
