The ew 300 IEM G2 system

With the Sennheiser evolution wireless in-ear monitoring system ew 300 IEM G2 (suitable for both stage and broadcast use), musicians, video and sound amateurs, reporters/broadcasters, etc. can directly monitor the received sound signals without troublesome cables or monitor speakers being required. In addition, the system can also be used for any application where talkback signals are to be transmitted.

The evolution wireless in-ear monitoring system ew 300 IEM G2 is a high-quality state-of-the-art RF transmission systems with a high level of operational reliability and ease of use. Transmitter and receiver permit wireless transmission with studio-quality sound. The excellent transmission reliability of the ew 300 IEM G2 system is based on the use of

• further optimized PLL synthesizer and microprocessor technology,
  • the HDX noise reduction system,
• the pilot tone squelch control (during stereo operation),
  • and the scan function for scanning the channel banks for free channels.

The channel bank system

The ew 300 IEM G2 system is available in five UHF frequency ranges with 1440 transmission/receiving frequencies per frequency range. Please note: Frequency usage is different for each country. Your Sennheiser agent will have all the necessary details on the available legal frequencies for your area.

Range A: 518 to 554 MHz

Range B: 626 to 662 MHz

Range C: 740 to 776 MHz

Range D: 786 to 822 MHz

Range E: 830 to 866 MHz

Transmitter and receiver have nine channel banks with up to 12 switchable channels each.

graph TD
    A["channel bank 1...8"] --> B—including Channel 1 (preset frequency)]
    A --> C—including Channel 2 (preset frequency)]
    A --> D—including Channel 12 (preset frequency)]
    A --> E—including Channel 1 (freely selectable frequency)]
    A --> F—including Channel 2 (freely selectable frequency)]

    H["channel bank U"] --> I—including Channel 1 (preset frequency)]
    H --> J—including Channel 2 (preset frequency)]
    H --> K—including Channel 12 (preset frequency)]

The channel banks “1” to “8” have switchable channels that are factory-preset to a transmission/receiving frequency (see enclosed frequency table). These transmission/receiving frequencies cannot be changed but have been preset so that e.g. country-specific regulations on frequency usage are taken

into account. The channel bank "U" (user bank) has up to 12 switchable channels to store your selection out of 1440 transmission/receiving frequencies that are freely selectable within the preset frequency range.

An advantage of the factory-preset frequencies is that

• the system is ready for immediate use after switch-on,
• several in-ear monitoring systems can be operated simultaneously on the preset channels without causing intermodulation interference.

Safety instructions

Never open electronic units! If units are opened by customers in breach of this instruction, the warranty becomes null and void.

Keep the units away from central heating radiators and electric heaters. Never expose them to direct sunlight.

Use the units in dry rooms only.

Use a damp cloth for cleaning the units. Do not use any cleansing agents or solvents.

Attention! High Volume!

This is a professional transmission system. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.

This system is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the sound pressure corresponding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be shortened in order to prevent 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.

Inserting and replacing the batteries

For powering the EK 300 IEM G2 receiver, two 1.5 V AA size batteries are required.

Press the two unlocking buttons 10 and open the battery compartment cover 9.
Insert the two batteries as shown in the diagram on the left. Please observe correct polarity when inserting the batteries.
▶ Close the battery compartment. The battery compartment cover ⑨ locks into place with an audible click.

Inserting and charging the accupack

The receiver can also be powered via the rechargeable Sennheiser BA 2015 accupack. Insert the accupack into the battery compartment as described above. The transmitter has two charging contacts ⑤ and a sensing contact on its short sides. The accupack can be recharged while remaining in the transmitter. Insert the transmitter into the L 2015 charger (see operating manual of the L 2015 charger).

Note:

For accupack operation of the receiver, only use the BA 2015 accupack in order to ensure optimum operational reliability. For charging the accupack, only use the L 2015 charger. Both the accupack and the charger are available as accessories. The accupack is fitted with an integrated sensor which is – via a third contact – monitored by the electronics of the receiver and the charger. The sensor is necessary for the following control purposes:

• The taking into account of the different voltage characteristics of primary cells (batteries) and accupacks. The battery status indications on the displays, the transmission of transmitter battery status information to the rack-mount receivers and the switch-off thresholds at the end of the operating time are corrected correspondingly. Due to the missing sensor, individual rechargeable battery cells will not be identified as accupacks.
• The monitoring of the accupack temperature during charging in the L 2015 charger.
• The prevention of improper charging of inserted primary cells (batteries). Due to the missing sensor, individual rechargeable battery cells will also not be charged in the L 2015 charger.

Adjustment tips for the operating menu

Switching between channel banks

BANK Bank

Via the "Bank" menu, you can switch between the nine channel banks of the ew 300 IEM G2 transmitter and receiver. The channel banks "1" to "8" have up to 12 switchable channels that are factory-preset to a transmission/receiving frequency (see "The channel bank system" on page 42). The channel bank "U" (user bank) also has up to 12 switchable channels to store your selection out of 1440 transmission/receiving frequencies that are freely selectable within the preset frequency range.

When switching from one channel bank to another, the channel with the lowest channel number is automatically displayed. If, during the last scan of this channel bank, an interfering frequency was detected on the channel with the lowest channel number, the receiver display panel automatically displays the next free channel (see below).

Switching between the channels in a channel bank

CHAN Channel

Via the "Channel" menu, you can switch between the channels in a channel bank.

Always set the transmitter and the receiver of a transmission link to the same channel. After scanning a channel bank (see “Scanning the channel banks for free channels (receiver only)” on page 62), only the free channels are displayed. Set the transmitter to one of the free channels

Selecting the frequencies to be stored in the channel bank "U"

TUNE Tune

Via the “Tune” menu, you can select the frequencies to be stored in the channel bank “U” (user bank).

When you have selected one of the channel banks "1" to "8" and then select the "Tune" menu, the transmitter or receiver automatically switches to channel 01 of the channel bank "U". In this case, "U.01" briefly appears on the display.

▶ Use the ▲/▼ buttons to select the desired transmission or receiving frequency. Transmission and receiving frequencies are tunable in 25-kHz steps within a switching bandwidth of 36 MHz max. For intermodulation-free frequencies, please refer to the enclosed frequency table.

Scanning the channel banks for free channels (receiver only)

SCAN

Before putting one or several transmission links into operation, you should scan the selected channel bank for free channels.

Starting the scan and storing the scan result

Before starting the scan, switch all transmitters of your system off, since channels used by switched-on transmitters will not be displayed as “free channels”.
▶ Select the "SCAN" menu.
Select "START" and confirm your selection by pressing the SET button. After the scan is completed, the number of free channels is displayed. Pressing the SET button once more will store the scan result and lock all channels that are used or subject to interference.

Releasing locked channels

▶ Select the "SCAN" menu.
▶ Select "CLEAR" and confirm your selection by pressing the SET button. All channels in this channel bank can now be selected again.

Multi-channel operation

For multi-channel operation, only use the free channels in a channel bank.

Before putting the transmission links into operation, we recommend performing an auto scan.

▶ Select a channel bank on a receiver.
▶ Scan this channel bank for free channels. If not enough free channels are available in the selected channel bank, repeat the scan with another channel bank.
Apply the scan result to all other transmitters and receivers.

Adjusting the squelch threshold (receiver only)

The receiver is equipped with a squelch that can be adjusted via the "SQELCH" menu. 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.

Note:

Before adjusting the squelch threshold to a different setting, use the volume control 13 to set the volume for the connected headphones to the minimum.

There are three possible squelch settings:

• LO = low
• MID = middle
• HI = high

Selecting the setting "LO" reduces the squelch threshold, selecting the setting "HI" increases the squelch threshold. Adjust the squelch threshold – with the transmitter switched off – to the lowest possible setting that suppresses hissing noise.

13 5.3025Ω B.CN MAX RF ON LOW BATT RF

IMPORTANT! Notes:

• If the squelch threshold is adjusted too high, the transmission range will be reduced. Therefore, always adjust the squelch threshold to the lowest possible setting.
• When in the setting mode of the "SQELCH" menu, pressing the ▼ button for more than three seconds will switch the squelch off. "SQ.OFF" appears on the display. If no RF signal is being received, his-sing noise will occur. This setting is for test purposes only.

Stereo/FOCUS selection (receiver only)

ST-FOC

Via the "ST-FOC" menu, you can switch between stereo and FOCUS operation.

In both operating modes, the SR 300 IEM G2 stereo transmitter has to be set to stereo operation.

When the receiver is set to stereo operation, the left-right signals are available as usual.

When the receiver is set to FOCUS operation, the left-right signals are mixed and are available as a mono signal in both headphone channels. Use the ▼/▲ rocker button to adjust the relative levels of the two separate channels in the mixed mono signal (see “Adjusting the balance” on page 53).

Limiting the volume at the headphone output (receiver only)

LTD

Via the "LTD" menu, you can switch the limiter on and off. With the limiter switched on, the volume at the headphone output will be reduced.

Activating/deactivating the frequency boost (receiver only)

HI-BST

Via the "HI-BST" menu, you can boost the AF frequency response at 10 kHz. As a result, headphones with magnetic transducers sound better.

Adjusting the sensitivity (transmitter only)

Sensitiv

1.01 530.050MHz B.CH AFI -30 -20 -10 0 PEAK AFII -30 -20 -10 0 PEAK

To match the transmitter to the output level of the connected unit (e.g. mixing console), you can adjust the input sensitivity in four steps of 8 dB via the "Sensitiv" menu.

The input sensitivity is adjusted too high when close talking distances, speakers with loud voices or loud music passages cause overmodulation in the transmission link. In this case, the transmitter's "PEAK" warning will light up and the receiver's level display for audio signal "AF" will show full deflection.

If, on the other hand, the sensitivity is adjusted too low, the transmission link will be undermodulated, which would result in a signal with high background noise.

The sensitivity is correctly adjusted when the level display for audio signal "AF" shows full deflection only during the loudest passages.

Entering a name

NAME Name

Via the "Name" menu, you can enter a freely selectable name for the transmitter and the receiver. You can, for example, enter the name of the performer for whom the adjustments have been made.

The name can be displayed on the standard display and can consist of up to ten characters (transmitter) and up to six characters (receiver) such as:

• letters (without pronunciation marks),
• numbers from 0 to 9,
• special characters e.g. () - . _ and spaces.

To enter a name, proceed as follows:

Press the SET button to get into the setting mode of the "Name" menu. The first segment starts flashing on the display.
With the ▲/▼ buttons you can now select a character. By briefly pressing

a button, the display jumps either forwards or backwards to the next character. If you hold down a button, the display starts cycling continuously.

▶ Press the SET button to change to the next segment and select the next character.
Have you entered the name completely? Press the SET button to store your setting and to return to the previous menu level.

Loading the factory-preset default settings

RESET Reset

Via the "Reset" menu, you can load the factory-preset default settings. With the receiver, however, the selected setting for the pilot tone remains unchanged. After the reset, the unit is restarted and the standard display is shown on the display panel.

Activating/deactivating the pilot tone evaluation (receiver only)

PILOT Pilot

Via the "Pilot" menu, you can activate or deactivate the pilot tone evaluation of the receiver. The pilot tone is used

• to code the transmitter's stereo signal,
• to support the squelch function (Squelch).

During stereo operation, the transmitter adds the pilot tone to the transmitted stereo signal and the receiver detects and evaluates the pilot tone. When the transmitter is set to mono operation, deactivate the pilot tone evaluation on the receiver.

You can combine units of first and second generation ew 300 IEM systems without any problems.

Adjusting the contrast of the graphic display (transmitter only)

LCD-Contr

Via the "LCD Contr" menu, you can adjust the contrast of the graphic display in 16 steps.

Stereo/Mono selection (transmitter only)

Mode

Via the "Mode" menu, you can switch the transmitter between mono and stereo operation.

Note:

DC IN 10,5 - 16V / 300mA AF IN BAL / UNBAL L (I) + M R (R) DATA 9

Connect any unit that only delivers a mono signal to the transmitter's left XLR-3F socket ⑨ and set the transmitter to mono operation. The receiver automatically "identifies" the transmitted audio signal and does not need to be set to mono operation. However, you have to deactivate the pilot tone evaluation on the receiver.

Activating/deactivating the lock mode

LOCK Lock

Via the "Lock" menu, you can activate or deactivate the lock mode.

1.01 530.050MHz B.CH AFI -30 -20 -10 0 PEAK AFII -30 -20 -10 0 PEAK

The lock mode icon on the display indicates that the lock mode is activated.

To deactivate the lock mode, first press the SET button. Then press the ▲/▼ buttons to select "Lock Off". If you confirm your selection by pressing the SET button, the buttons can be operated as usual.

Recommendations and tips

... for the EK 300 IEM G2 receiver

- The antenna of the EK 300 IEM G2 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 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 SR 300 IEM G2 transmitter, transmission conditions are unfavourable, you should use a remote antenna which is connected via antenna cable.
• To avoid overmodulating the receiver, observe a minimum distance of 5 m between transmitting and receiving antennas.
• Observe a minimum distance of 50 cm between transmitting antennas and metal objects (such as cross members or reinforced-concrete walls).

... for multi-channel operation

• For multi-channel operation, you can only use the channels in a channel bank. Each of the channel banks "1" to "8" accommodates up to 12 factory-preset frequencies which are intermodulation-free. For alternative frequency combinations, please refer to the enclosed frequency table. The freely selectable frequencies can be selected via the "Tune" menu and can be stored in the channel bank "U".
• When using several transmitters simultaneously, interference can be avoided by maintaining a minimum distance of 20 cm between two transmitters. For multi-channel applications, use the AC 2 transmitter combiner (see “Accessories” on page 73).

Care and maintenance

Use a slightly damp cloth to clean the units from time to time.

Note:

Do not use any cleansing agents or solvents.

HDX noise reduction

RF link 0 dB -10 dB -20 dB -30 dB -40 dB -50 dB -60 dB -70 dB -80 dB -90 dB -100 dB -110 dB Transmitter HDX Inherent noise of the RF link HDX 0 dB -10 dB -20 dB -30 dB -40 dB -50 dB -60 dB -70 dB -80 dB -90 dB -100 dB -110 dB Receiver

The evolution wireless G2 series is equipped with HDX, the Sennheiser noise reduction system that reduces RF interference. It increases the signal-to-noise ratio in wireless audio transmission to more than 110 dB.

HDX is a wideband commander system which compresses the audio signal in the transmitter in a 2:1 ratio (related to dB) to lift it above the inherent noise floor of the RF link. In the receiver the signal is expanded in an identical and opposite way in a 1:2 ratio to restore the original signal, at the same time reducing the RF noise to below the noise floor of the receiver.

HDX has been specially developed for high quality radiomicrophone systems.

Note:

Only transmitters and receivers that are equipped with HDX can work correctly with each other. If non HDX equipment was mixed with HDX, the dynamic range would be drastically reduced and the transmission would sound blunt and flat. HDX is permanently active and cannot be switched off.

Wireless transmission systems

With the ew 300 IEM G2 system, Sennheiser puts an end to cable tangles and enables complete freedom of movement. The systems operate exclusively in the UHF band. UHF transmission is extremely reliable and is far less prone to interference than the overcrowded VHF band – harmonics from mains units, fluorescent tubes, refrigerators, computers, etc. are virtually eliminated. Also indoor propagation of UHF radio waves is better than VHF so that the RF power can be kept low – this is also an advantage when using multi-channel systems. Finally, UHF frequency ranges are being approved all over the world for radiomicrophone usage – in some countries licence-free.

Correct adjustment of transmitter sensitivity is vital. Too high and you get overmodulation and distortion, too low and you get undermodulation and a noisy signal. Please set the sensitivity correctly for the microphone/usage and check it before every performance to ensure best operation.

Squelch

Pilot tone squelch

When the transmitter is set to stereo operation, it adds a 19-kHz pilot tone to the audio signal. The receiver checks incoming audio signals to see if the pilot tone is present. In the absence of the 19-kHz signal, the receiver's audio output will remain muted, even if a strong RF signal is present.

This prevents strong interfering signals from causing hissing noise in the receiver when the transmitter is switched off.

Field strength-dependent squelch

Depending on the strength of the received RF signal, the receiver's audio output is opened or muted. Via the "SQELCH" menu of the receiver, the squelch threshold can be adjusted in three steps (LO, MID, HI).
