The SKM 500 G2 radiomicrophone family The SKM 500 G2 radiomicrophone family is part of the evolution wireless series ew 500 G2. With this series, Sennheiser offers high-quality state-of-the-art RF transmission systems with a high level of operational reliability and ease of use. Transmitters and receivers permit wireless transmission with studio-quality sound.
Safety instructions Never open an electronic unit! If units are opened by customers in breach of this instruction, the warranty becomes null and void. Use the unit in dry rooms only. Use a damp cloth for cleaning the unit. Do not use any cleansing agents or solvents.
Areas of application The SKM 500 G2 radiomicrophone family can be combined with receivers of the ew 500 G2 series (EM 500 G2 rackmount receiver or EK 500 G2 bodypack receiver). The receivers are available in the same five UHF frequency ranges and are equipped with the same channel bank system with factory-preset frequencies.

Indications and displays LC display panel Alphanumeric display “B.
“MUTE” display The “MUTE” display appears on the display panel when the radiomicrophone is muted (see “Muting the radiomicrophone” on page 46). Modulation display The level display for audio signal “AF” shows the modulation of the radiomicrophone. When the audio input level is excessively high, the level display for audio signal “AF” shows full deflection for the duration of the overmodulation.
Preparing the radiomicrophone for use Inserting/replacing the batteries For powering the 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.
Push the battery compartment radiomicrophone’s body. into the Screw the display section tight. Note: For accupack operation of the radiomicrophone, 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 radiomicrophone and the charger.
Gently ease the capsule out of the contacts and then pull it out of the housing as shown. Do not touch the contacts and the diaphragm! Insert the new capsule. Secure the capsule by tightening the screw. Note: The screw mechanically secures the microphone capsule. If the screw is missing, malfunctions may occur during tough use.
Using the radiomicrophone Switching the radiomicrophone on/off The radiomicrophone can only be switched off when the standard display is shown on the display panel. When in the operating menu, briefly pressing the ON/OFF button will cancel your entry (ESC function) and return you to the standard display with the last stored settings. Note: Remove the batteries or the accupack when the radiomicrophone will not be used for extended periods of time.
Muting the radiomicrophone The radiomicrophone has a MUTE switch that noiselessly mutes the audio signal without switching the radiomicrophone off. Turn the protective cap at the bottom of the radiomicrophone so that the MUTE switch becomes accessible. . Set the MUTE switch to the position ’MUTE’. The “MUTE” display appears on the radiomicrophone’s display panel.
The operating menu A special feature of the Sennheiser ew 500 G2 series is the similar, intuitive operation of transmitters and receivers. As a result, 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 radiomicrophone on, the standard display is shown on the display panel. Getting into the operating menu Press the SET button to get from the standard display into the operating menu. The last selected menu flashes on the display. Selecting a menu Press the / buttons to select a menu. Press the SET button to get into the setting mode of the selected menu.
Storing a setting Press the SET button to store the setting. “STORED” appears on the display, indicating that the setting has been stored. The display then returns to the top menu level. With most menus, new settings become effective immediately without having to be stored. An exception are the “BANK”, “CHAN”, “TUNE” and “RESET” menus. With these menus, new settings only become effective after they have been stored (“STORED” appears on the display, indicating that the setting has been stored).

Adjustment tips for the operating menu Switching between channel banks – BANK Via the “BANK” menu, you can switch between the radiomicrophone’s nine channel banks. Each of the channel banks “1” to “8” has up to 20 switchable channels that are factory-preset to a transmission frequency (see “The channel bank system” on page 36).
In this case, “U.01” briefly appears on the display. Use the / buttons to select the desired transmission frequency. Transmission 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. Adjusting the sensitivity – SENSIT Via the “SENSIT” menu, you radiomicrophone’s input sensitivity.
Selecting the standard display – DISLPY Via the “DISPLY” menu, you can select the standard display: Selectable standard display Contents of standard display “FREQ” “NAME” “CHAN” Entering a name – NAME Via the “NAME” menu, you can enter a freely selectable name for the radiomicrophone. You can, for example, enter the name of the performer for whom the adjustments have been made.
Activating/deactivating the pilot tone transmission – PILOT Via the “PILOT” menu, you can activate or deactivate the pilot tone transmisssion. The pilot tone supports the receiver’s squelch function (Squelch) and protects against interference due to RF signals from other units. The transmitter adds an inaudible signal, known as the pilot tone, to the transmitted signal. The receiver detects and evaluates the pilot tone, and is thus able to identify the signal of the matching transmitter and mute all others.

Recommendations and tips ... for the SKM 500 G2 radiomicrophone y Hold the SKM 500 G2 in the middle of the microphone body. Holding it close to the sound inlet basket will influence the microphone’s pick-up pattern, holding it at the lower part of the body will reduce the transmitter’s range. y You can vary the bass reproduction by increasing/ decreasing the talking distance. y For best results, make sure that the transmitter sensitivity is correctly adjusted. ...
Care and maintenance Use a slightly damp cloth to clean the radiomicrophone from time to time. Note: Do not use any cleansing agents or solvents. To clean the radiomicrophone’s sound inlet basket, proceed as follows: Unscrew the sound inlet basket (turn counterclockwise) and remove it. Remove the foam insert. Use a slightly damp cloth to clean the sound inlet basket from the inside and ouside. Reinsert the foam insert.
