734 – 776

780 – 822

823 – 865

Each frequency range (A–E, G) offers 26 frequency banks with up to
24 channels each:

Channel 1 – frequency preset

Channel 2 – frequency preset

Frequency bank 1 ... 20

Channel 24 – frequency preset

Channel 1 – freely selectable frequency

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:

왘 Read the corresponding chapter on page 14.

If you want to set up the receiver on a flat surface:

왘 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.

왘 Do not place the receiver on delicate surfaces.

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.

왘 Make sure that the ambient temperature within the rack does not

exceed the permissible temperature limit specified in the specifications
(see page 54).

왘 Ensure sufficient ventilation; if necessary, provide additional ventila-

tion.

왘 Make sure that the mechanical loading of the rack is even.

왘 When connecting to the power supply, observe the information indi-

cated on the type plate. Avoid circuit overloading. If necessary, provide

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.

왘 If necessary, change from the “Soundcheck” standard display to one of

the other standard displays of your receiver.

Adjustment range: 5 to 25 dBμV, adjustable in 2-dB steps, can be

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.

왘 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 transmis­sion 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!

왘 Always make sure that the squelch is switched on (see below).

왘 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.

왘 Never change the squelch threshold during a live transmission.

Activating/deactivating the pilot tone evaluation

The pilot tone supports the receiver’s squelch function and protects
against interference due to RF signals from other devices.

Synchronizing transmitters with receivers

Synchronizing transmitters with
receivers

When synchronizing a transmitter with a receiver, please observe the
following:

왘 Only use a transmitter and a receiver from the same frequency

range (see the type plate on the transmitter and the receiver).

왘 Make sure that the desired frequencies are listed in the enclosed

frequency information sheet.

왘 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:

44

왘 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.

Synchronize a transmitter with the receiver via the infra-red interface

ew300 G3

(see page 22).
This establishes a transmission link between the transmitter and the
receiver.

Alternatively, you can set the channel on the transmitter manually:

왘 Make sure that you set the transmitter to the same frequency bank and

the same channel as the receiver (see the instruction manual of the
transmitter).

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
product page on our website at www.sennheiser.com.

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).

Operation

without network

왘 Connect the receivers in a network (see page 18).

왘 Launch the “Wireless Systems Manager” (WSM) software.

왘 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.

왘 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.

If you want to set up a multi-channel system without using the WSM,
proceed as follows:

왘 Switch off all transmitters of your system that are to be automatically

configured.
Channels used by switched-on transmitters are displayed as “used”.

45

Synchronizing transmitters with receivers

왘 With one of the receivers, perform a frequency preset scan to scan the

왘 Switch one of the transmitters on.

왘 Synchronize this transmitter with the receiver via the infra-red inter-

face

(see page 22).
This establishes a transmission link between the transmitter and the
receiver.

왘 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:

왘 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.

46

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
“U6”, it might be that the receiving frequencies are not inter­modulation-free.

To ensure that the desired frequencies are intermodulation-free:

왘 Contact your Sennheiser partner (see www.sennheiser.com).

If you want to use the frequency banks “U1” to “U6”:

왘 Make sure to use receivers from the same frequency range (see page 6

and the type plates of the devices).

왘 Only use frequencies that are approved and legal in your country.

왘 Set each receiver to the same frequency bank (see page 38).

Synchronizing transmitters with receivers

왘 On one of the receivers, select a channel within this frequency bank

(see page 38).

왘 Assign this channel one of the receiving frequencies (see page 38).

왘 Synchronize a transmitter with the receiver (see page 22).

OR

왘 Manually set the transmitter to the same frequency bank, channel and

frequency that you set on the receiver.

왘 Repeat for the remaining transmitters and receivers as described

above.

47

Cleaning the receiver

Cleaning the receiver

CAUTION! Liquids can damage the electronics of the receiver!

Liquids entering the housing of the receiver can cause a short-circuit and
damage the electronics.

왘 Keep all liquids away from the receiver.

왘 Before cleaning, disconnect the receiver from the mains.

왘 Use a cloth to clean the receiver from time to time. Do not use any

solvents or cleansing agents.

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 factory­preset 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 appli­cations (see page 52).
