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

graph TD
    A["Frequency bank 1 ... 20"] --> B["Channel 1 – frequency preset"]
    A --> C["Channel 2 – frequency preset"]
    A --> D["Channel 24 – frequency preset"]
    E["Frequency bank U1 ... U6"] --> F["Channel 1 – freely selectable frequency"]
    E --> G["Channel 2 – freely selectable frequency"]
    E --> H["Channel 24 – freely selectable frequency"]

Each of the channels in the frequency banks "1" to "20" has been factory-preset 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 SK 300 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 intermodulation-free.

Areas of application

The bodypack transmitter can be combined with the EM 300 G3 rack-mount receiver.

The bodypack transmitter adds an inaudible signal, known as the pilot tone, to the transmitted signal. The receiver detects and evaluates the pilot tone.

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

Devices of the ew 300 G1 series (generation 1) do not support the pilot tone function. Therefore, please observe the following when combining a bodypack transmitter or receiver of the ew 300 G3 series (generation 3) with devices from an earlier evolution wireless generation:

Transmitter Receiver Make sure to ...

ew G3 / w G2 w C3 / w G2e... activate the pilot tone function on both bodypack transmitter and receiver.

ew G3 w G1 ... deactivate the pilot tone function on the ew 300 G3 bodypack transmitter.

ew G1 w G3 ... deactivate the pilot tone function on the ew 300 G3 receiver.

Adjusting the contrast of the display panel – "LCD Contrast"

You can adjust the contrast of the display panel in 16 steps.

Resetting the settings made in the operating menu – "Reset"

When resetting the settings made in the operating menu, only the selected settings for the pilot tone and for the frequency banks "U1" to "U6" remain unchanged. For an overview of the factory-preset default settings, refer to the supplied frequency information sheet.

Displaying the software revision – "Software Revision"

You can display the current software revision of the body-pack transmitter.

For information on software updates, visit the SK 300 G3 product page at www.sennheiser.com.

Synchronizing the bodypack transmitter with a receiver

When synchronizing the bodypack 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 the bodypack transmitter with the receiver – individual operation

Upon delivery, the bodypack transmitter and the receiver are synchronized with each other.

If, however, you cannot establish a transmission link between bodypack transmitter and receiver, you have to synchronize the channels of the devices.

For information on automatic synchronization of the body-pack transmitter with the receiver (individual operation), refer to the instruction manual of the receiver. This information is marked with the silicon.

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

Make sure that you set the bodypack transmitter to the same frequency bank and the same channel as the receiver (see page 21).

If you still cannot establish a transmission link, refer to the chapter "If a problem occurs ..." on page 30.

Synchronizing bodypack transmitters with receivers – multi-channel operation

Combined with ew 300 G3 receivers, ew 300 G3 bodypack transmitters can form transmission links that can be used in multi-channel systems.

For information on automatic synchronization of bodypack transmitters with receivers (multi-channel operation), refer to the instruction manual of your receiver.

For more information on multi-channel operation, visit the SK 300 G3 product page at www.sennheiser.com.

Cleaning the bodypack transmitter

CAUTION! Liquids can damage the electronics of the bodypack transmitter!

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

▶ Keep all liquids away from the bodypack transmitter.

▶ Use a cloth to clean the bodypack transmitter from time to time.
Do not use any solvents or cleansing agents.

Recommendations and tips

... for the ME 2 and ME 4 clip-on microphones

• To reduce level variations to a minimum when the user turns his or her head away from the microphone, attach the microphone as centrally as possible.
• To protect the microphone against excessive sweat/moisture, avoid direct skin contact.
• Attach the microphone carefully and conduct the cable so that noise due to friction is avoided.
• Always use the ME 4 directional microphone with a windshield and direct the microphone towards the sound source (e.g. mouth).

... for the ME 3 headmic

• Always use the microphone with a pop shield and position the microphone at the corner of the mouth.
• You can vary the bass reproduction by increasing/decreasing the talking distance.
• Make sure that the sound inlet is directed towards the mouth. The sound inlet is marked with a little dot.

... for the bodypack transmitter

• Make sure that the antenna and the microphone cable do not cross.
• The antenna should hang freely and be at least 1 cm away from the body. The antenna must not be in direct contact with the skin.
• 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

• For multi-channel operation, 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.
• When using several transmitters simultaneously, interference can be avoided by maintaining a minimum distance of 20 cm between two transmitters.
