Indications and displays on the receiver Transmitter battery status indication The 4-step transmitter battery status display on the receiver display panel provides information on the transmitter’s remaining battery/accupack BA 2015 capacity: 3 segments: 2 segments: 1 segment: Battery icon flashing: capacity approx. 100 % capacity approx. 70 % capacity approx. 30 % LOW BAT In addition, the text “LOW BAT” (backlit in red) flashes in alternation with the standard display.
Diversity display The EM 300 G2 receiver operates on the true diversity principle (see “Diversity reception“ on page 39). The diversity display indicates whether diversity section I (i.e. antenna 1) or diversity section II (i.e. antenna 2) is active. Button backlighting In standby operation, the ON button is backlit in red. When the receiver is switched on, the SET button and the / button are additionally backlit in green.
AF peak indication (SK 300 G2 only) The yellow LED (AF PEAK) at the front of the SK 300 G2 lights up when the audio input level is excessively high (AF peak) and overmodulates the transmitter. At the same time, the 7-step level display for audio signal “AF” shows full deflection for the duration of the overmodulation. “PILOT” display The “PILOT” display lights up when the pilot tone evaluation is activated.
Preparing the components for use EM 300 G2 rack-mount receiver Mounting the receiver feet To ensure that the receiver cannot slip on the surface on which it is placed, four self-adhesive soft rubber feet are supplied. Ensure that the base of the receiver is clean before mounting the rubber feet. Fix the rubber feet to the base of the receiver by peeling of the safety paper and fitting them as shown in the digram on the left.
Connecting the amplifier/mixing console The EM 300 G2’s audio outputs are available as an XLR-3M socket and a ¼” (6.3 mm) jack socket , allowing you to simultaneously connect two units (e.g. amplifier, mixing console). The adjusted audio output level is common for both sockets. Connect the amplifier/mixing console to the XLR-3M socket or the ¼” (6.3 mm) jack socket . For detailed information on balanced and unbalanced connection, please refer to the section “onnector assignment” on page 41.
To mount two EM 300 G2 into a rack: Place the two receivers side by side onto a flat surface, their bottom sides facing upwards. Align the connecting plate over the holes in the bottom sides of the receivers. Secure the connecting plate to the receivers using eight of the supplied recessed head screws (M 3x6). Hook the two rack mount “ears” to the front panels of the receivers.
SK 300 G2 bodypack transmitter Inserting and replacing the batteries For powering the SK 300 G2 bodypack transmitter, use two 1.5 V AA size batteries. Press the two unlocking buttons cover . and open the battery compartment 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 into place with an audible click.
Attaching the microphones Use the microphone clips to attach the ME 2 and ME 4 clip-on microphones to clothing (e.g. tie, lapel). Adjust the ME 3 headmic so that a comfortable and secure fit is ensured. Positioning the microphones The ME 3 and ME 4 microphones are directional microphones, i.e. their sound inlet should always be directed towards the sound source (e.g. mouth). The ME 2 with omni-directional pick-up pattern picks up sound equally from all directions.
SKM 300 G2 radiomicrophone Inserting and replacing the batteries For powering the SKM 300 G2 radiomicrophone, you can either use two 1.5 V AA size batteries or the rechargeable Sennheiser BA 2015 accupack. Unscrew the display section from the radiomicrophone’s body ( by turning it counterclockwise. Slide back the display section as far as it will go. Open the battery compartment cover . Insert the two batteries or the BA 2015 accupack as shown in the diagram on the left.
Using the components Switching the components on/off ew 300 G2 transmitters and receivers can only be switched off when the standard display is shown on the display panel. Within the operating menu, the ON button (receiver) or the ON/OFF button (transmitters) serves as the ESC (cancel) key, i.e you cancel your entry and return to the standard display. Note: Remove the batteries or the accupack when the units will not be used for extended periods of time.
Muting the transmitters Both transmitters have a MUTE switch that noiselessly mutes the transmitter’s audio signal without switching the transmitter off. Muting the SK 300 G2 bodypack transmitter Set the MUTE switch to the position ’MUTE’. The “MUTE” display appears on the transmitter display panel. Provided that the pilot tone function is activated on both the transmitter and the receiver, the “MUTE” display also appears on the receiver display panel.
The operating menu A special feature of the Sennheiser ew 300 G2 series is the similar, intuitive operation. As a result, the units are easy to operate and adjustments to the settings can be made quickly and “without looking” – even in stressful situations, for example on stage or during a live show or presentation.

Working with the operating menu By way of example of the “Tune” menu, this section describes how to use the operating menu. After switching the unit on, the standard display is shown on the display panel. EM 300 G2 Transmitters Getting into the operating menu Press the SET button to get from the standard display into the operating menu. The last menu selected flashes on the display. With the receiver, the current setting is additionally displayed.
Exiting the operating menu Select the “Exit” menu to exit the operating menu and to return to the standard display. When you have entered the operating menu, the ON/OFF button or the ON button (EM 300 G2 receiver only) serves as the ESC (cancel) key, i.e. by briefly pressing the ON/OFF or POWER button, you cancel your entry and return to the standard display.

Adjustment tips for the operating menu Switching between channel banks BANK Bank Via the “Bank” menu, you can switch between the nine channel banks. The channel banks “1” to “8” have eight switchable channels that are factorypreset to a transmission/receiving frequency (see “The channel bank system“ on page 4). The channel bank “U” (user bank) has eight switchable channels to store your selection out of 1440 transmission/receiving frequencies that are freely selectable within the preset frequency range.
Scanning the channel banks for free channels (EM 300 G2 only) Scan Before putting one or several transmission links into operation, you should scan the channel banks for free channels.

Recommendations and tips ... for the ME 2 and ME 4 clip-on microphones y 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. y To protect the microphone against excessive sweat/moisture, avoid direct skin contact. y Attach the microphone carefully and conduct the cable so that noise due to friction is avoided.
... for multi-channel operation y For multi-channel operation, you can only use the channels in a channel bank. Each of the channel banks “1” to “8” accommodates eight factorypreset 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”.
