Important safety instructions

System

Read this instruction manual. Keep this instruction manual. Always include this instruction manual when passing the devices and the mains unit on to third parties. Heed all warnings and follow all instructions in this instruction manual. Only clean the devices when they are not connected to the mains. Use a cloth for cleaning. Only use attachments/accessories specified by Sennheiser. Refer all servicing to qualified service personnel. Servicing is required if the devices or the mains unit have been damaged in any way, liquid has been spilled, objects have fallen inside, the devices have been exposed to rain or moisture, do not operate properly or have been dropped. WARNING: To reduce the risk of fire or electric shock, do not use the devices and the mains unit near water and do not expose them to rain or moisture.

Receiver

Only use the supplied mains unit. Unplug the mains unit from the wall socket to completely disconnect the device from the mains, during lightning storms or when unused for long periods of time. Only operate the mains unit from the type of power source specified in the chapter Specifications (see page 31). Ensure that the mains unit is in a safe operating condition and easily accessible, properly plugged into the wall socket, only operated within the permissible temperature range, not covered or exposed to direct sunlight for longer periods of time in order to prevent heat accumulation (see Specifications on page 31). Do not block any ventilation openings. Install the device in accordance with the instructions given in this instruction manual. Do not install the device and the mains unit near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that produce heat. Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Danger due to high volumes This device 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 hearing 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.

Putting the devices into operation

EM 100 receiver

You can set up the receiver on a flat surface or mount it into a 19 rack. For information on rack mounting, refer to the instruction manual of the EM 100 receiver available on the ew G3 product page at www.sennheiser.com.
Setting up the receiver on a flat surface
Place the receiver on a flat, horizontal surface. Please note that the device feet can leave stains on delicate surfaces. The stacking elements are designed to help protect the operating elements from damage or deformation, e.g. if the receiver is dropped. Therefore, fasten the stacking elements, even if you do not want to stack your receivers. Fastening the stacking elements To fasten the stacking elements : Unscrew and remove the two recessed head screws (M4x8) on each side of the receiver (see diagram). Secure the stacking elements to the sides of the receiver using the previously removed recessed head screws (see diagram).

Fitting the device feet

The device feet are fitted to the base of the receiver (see diagram). If you want to stack receivers (see following section), only fit the device feet to the base of the lowermost receiver. Clean the base of the receiver where you want to fix the device feet. Fix the device feet to the base of the receiver by peeling off the backing paper and fitting them as shown on the left.
Putting the devices into operation Stack several receivers on top of each other.

Stacking receivers

CAUTION!
Danger of injury due to toppling receiver stacks! High receiver stacks can easily topple over. Place the stack on an absolutely flat surface. Secure the stack against toppling over. Fasten the stacking elements as described in the previous section. Stack the receivers so that the recesses of the stacking elements completely engage with each other.
Connecting the rod antennas
The supplied rod antennas are suitable for use in good reception conditions. Connect the antennas. You have the following options: You can connect the rod antennas to the rear of the receiver. You can use the optional AM 2 antenna front mount kit and mount the rod antennas to the front of the receiver (see the instruction manual of the EM 100 receiver available on the ew G3 product page at www.sennheiser.com). Align the antennas in a V-shape. When using more than one receiver, we recommend connecting remote antennas and, if necessary, using Sennheiser antenna accessories. Fore more information, visit the ew G3 product page at www.sennheiser.com.

Connecting an amplifier/mixing console
The receivers XLR-3M socket and the (6.3 mm) jack socket are connected in parallel. Use a suitable cable to connect the amplifier/mixing console to the XLR-3M socket or the (6.3 mm) jack socket. Via the operating menu, adjust the audio output level (AF Out) of the receiver to the input of the amplifier or mixing console (see page 26). The audio output level is adjusted via the operating menu and is common for both sockets.
Connecting the mains unit
Only use the supplied mains unit. It is designed for the receiver and ensures safe operation. To connect the mains unit: Insert the connector of the mains unit into the socket of the receiver. Pass the cable of the mains unit through the cable grip. Slide the supplied country adapter onto the mains unit. Plug the mains unit into a wall socket.
SK 100 bodypack transmitter
Inserting the batteries/accupack
For powering the bodypack transmitter, you can either use two 1.5 V AA size batteries or the rechargeable Sennheiser BA 2015 accupack. Push the two catches in the direction of the arrows and open the battery compartment cover.
Insert the two batteries or the accupack as shown above. Observe correct polarity when inserting the batteries/accupack. Close the battery compartment. The battery compartment cover locks into place with an audible click.

Charging the accupack

To charge the BA 2015 accupack: Insert the bodypack transmitter into the L 2015 charger (optional accessory). The L 2015 charger can only charge the combination BA 2015 accupack/bodypack transmitter. Standard batteries (primary cells) or individual rechargeable battery cells cannot be charged.
Connecting the microphone cable/instrument cable
The audio input is designed for the connection of both condenser microphones and instruments (e.g. guitars). DC powering of the condenser microphones is via the audio input. Use one of the recommended Sennheiser microphones or the optional CI 1 instrument cable. Connect the 3.5 mm jack plug from the Sennheiser microphone or instrument cable to the 3.5 mm jack socket MIC/LINE.
Lock the 3.5 mm jack plug by screwing down the coupling ring of the cable. Via the operating menu, adjust the sensitivity of the microphone/line input.
Attaching and positioning the corresponding microphones

ME 2/ME 4 Use the microphone clip to attach the microphone to clothing (e.g. tie, lapel). The ME 2 clip-on microphone (shown on the right in the diagram) has an omni-directional pick-up pattern. It is therefore not necessary to position it precisely. Attach the ME 2 microphone as close as possible to the sound source. The ME 4 clip-on microphone (shown on the left in the diagram) has a cardioid pick-up pattern. Position the ME 4 microphone so that its sound inlet is directed towards the sound source (e.g. mouth). ME 3 Adjust the ME 3 headmic so that a comfortable and secure fit is ensured. The ME 3 headmic has a cardioid pick-up pattern. Position the microphone so that its sound inlet is directed towards the sound source (e.g. mouth).
Attaching the bodypack transmitter to clothing
You can use the belt clip to attach the bodypack transmitter to clothing (e.g. belt, waistband). The belt clip is detachable so that you can also attach the transmitter with the antenna pointing downwards. To do so, withdraw the belt clip from its fixing points and attach it the other way round. The belt clip is secured so that it cannot slide out of its fixing points accidentally.
To detach the belt clip: Lift one side of the belt clip as shown in the diagram on the right-hand side. Press down the belt clip at one fixing point and pull it out of the transmitter housing. Repeat for the other side.

SKM 100 radio microphone

The evolution wireless series ew 100 G2
With the evolution wireless series ew 100 G2, Sennheiser offers musicians, video and sound amateurs 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. The excellent transmission reliability of the ew 100 G2 series is based on the use of further optimized PLL synthesizer and microprocessor technology, the HDX noise reduction system, the pilot tone squelch control, the true diversity technology (rack-mount receiver only) and the scan function for scanning the channel banks for free channels.

The channel bank system

The ew 100 G2 systems are 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: Range B: Range C: Range D: Range E: 518 to 554 MHz 626 to 662 MHz 740 to 776 MHz 786 to 822 MHz 830 to 866 MHz
Transmitters and receivers have nine channel banks with four switchable channels each.
channel 1 channel 2 channel bank 1.8 channel 3 channel 4 preset frequency preset frequency preset frequency preset frequency
channel 1 channel 2 channel bank U channel 3 channel 4
freely selectable frequency freely selectable frequency freely selectable frequency freely selectable frequency
The channel banks 1 to 8 have four switchable channels that are factorypreset 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 four 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 systems are ready for immediate use after switch-on, several systems can be operated simultaneously on the preset channels without causing intermodulation interference.

Preparing the components for use
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. Attention! 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. Connecting the antennas
The supplied telescopic antennas can be mounted quickly and easily to the rear of the receiver and are suitable for all applications where good reception conditions provided a wireless transmission system is to be used without a large amount of installation work. Connect the telescopic antennas to the BNC sockets and at the rear of the receiver. Pull the telescopic antennas out and align the upwards in a V-shape.
Use remote antennas when the receiver position is not the best antenna position for optimum reception.
Connecting the mains unit The EM 100 G2 is powered via a mains unit. Pass the cable through the cable grip. Insert the DC connector on the mains cable into the DC socket.
Connecting the amplifier/mixing console The EM 100 G2s audio outputs are available as an XLR-3M socket and a (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 (6.3 mm) jack socket. For detailed information on balanced and unbalanced connection, please refer to the section Connector assignment auf Seite 91.

Inserting and replacing the batteries For powering the SKP 100 G2 plug-on transmitter, you can either use two 1.5 V AA size batteries or the rechargeable Sennheiser BA 2015 accupack.
Slide the battery compartment cover in the direction of the embossed arrow and opern the cover. Insert the two batteries or the BA 2015 accupack as shown in the diagram on the left. Please observe correct polarity when inserting the batteries/ accupack.
Close the battery compartment. The battery compartment cover locks into place with an audible click. Note: For accupack operation of the transmitter, 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 transmitter 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.
Plugging the plug-on transmitter onto a microphone Plug the transmitters XLR-3F socket onto the microphones XLR-3M socket. Tighten the locking ring as shown in the diagram on the left. Note: The transmitter uses the microphone body as an antenna therefore only microphones with a metal casing should be used for best signal transmission.
Inserting and replacing the batteries For powering the SKM 100 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 radiomicrophones 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. Please observe correct polarity when inserting the batteries/ accupack. Close the battery compartment cover. Push the battery compartment into the radiomicrophones body. Screw the display section tight. Note: For important informations on charging the accupack see: Inserting and replacing the batteries on page 67.
Changing the microphone head First remove the batteries/accupack as described above and leave the radiomicrophone open. Unscrew the sound inlet basket. Loosen the screw and put it to one side. 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. Put on the sound inlet basket and identification ring supplied with the new microphone head (NB: do NOT use the old basket, as the different heads use slightly differing internal foam) and screw it tight. Insert the batteries/accupack. Close the radiomicrophone and put it into operation. Note: Microphone capsule, sound inlet basket and foam insert form an acoustic unit and must therefore always be exchanged all together. Each microphone head comes with a color-coded identification ring to distinguish different microphone heads from each other (green = MD 835, blue = MD 845, red = ME 865).

Switching between the channels in a channel bank CHAN
Via the CHAN menu, you can switch between the four 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 (receivers only) on page 79), 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
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 intermodulationfree frequencies, please refer to the enclosed frequency table.
Scanning the channel banks for free channels (receivers only) SCAN
Before putting one or several transmission links into operation, you should scan the selected channel bank for free channels In order to ensure intermodulation-free operation of your system.
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 sensitivity (transmitters only) SENSIT
Via the SENSIT menu, you can adjust the modulation level of the transmitters. This changes the transmitters input sensitivity. 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 SK 100 G2s yellow LED (AF PEAK) will light up and the receivers level display for audio signal (AF) will show full deflection (see: Modulation display of the receiving transmitter on page 60). 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.

Note: For monitoring the adjusted sensitivity, the transmitters level display for audio signal (AF) always indicates the audio level even if the transmitter is muted.
The following figures are a guide to the best settings: Loud music/vocals: Presentations: Interviews: Musical instruments: electric guitars with single coil pickups: electric guitars with humbucker pickups: guitars with active electronics (active pickups, active EQs, piezo pickups): Special feature of the SKP 100 G2 plug-on transmitter: In order to be able to use highly sensitive directional condenser microphones with separate powering, the SKP 100 G2 plug-on transmitter offers a sensitivity range extended by 20 dB. With the transmitter plugged onto a directional condenser microphone, the following figures are a guide to the best settings: Loud music/vocals: Presentations: Interviews: 50 to 40 dB 40 to 30 dB 30 to 20 dB 10 to 0 dB 20 to 10 dB 30 to 20 dB 30 to 20 dB 20 to 10 dB 10 to 0 dB
Adjusting the audio output level (receivers only) AF OUT
Via the AF OUT menu, you can adjust the audio output level of the receivers. The level can be adjusted in eight steps. Adapt the level of the audio output (AF OUT) to the input of the connected unit. The following figures are a guide to the best settings: EM 100 G2 Line level input: Microphone level input: 0 bis +18 dB 24 bis 6 dB EK 100 Gbis +12 dB 30 bis 6 dB
Adjusting the squelch threshold (receivers only) SQELCH
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, set the volume on a connected amplifier to the minimum. There are three possible squelch settings: LO MID HI = low = middle = 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.

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. The squelch threshold is factory-preset to LO. When in the setting mode of the SQELCH menu, pressing the button (DOWN) for more than three seconds will switch the squelch off. SQ.OFF appears on the display. If no RF signal is being received, hissing noise will occur. This setting is for test purposes only.

. 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 four 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. When using several transmitters simultaneously, interference can be avoided by maintaining a minimum distance of 20 cm between two transmitters. Use special accessories for multi-channel applications (see: Accessories on page 93).

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. To clean the SKM 100 G2s 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. Replace the sound inlet basket on the SKM 100 G2 and screw it tight (taking care not to loose the colored identification ring).

Progress you can hear: The evolution wireless G2 series is equipped with HDX, the Sennheiser noise reduction system that reduces RF interference. It increases the signal-tonoise ratio in wireless audio transmission to more than 110 dB. HDX is a wideband compander 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. A 110 dB dynamic range signal is thus transmitted with an effective dynamic range of only 55 dB, which is above the 60 dB 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 100 G2 series, 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. There are three transmitter versions: The hand-held transmitter is a complete radiomicrophone in a single unit, the plug-on transmitter converts your favourite wired microphone into a radiomicrophone, the bodypack transmitter can accept a wide range of inputs including: omni-directional or cardioid clip-on microphones, head-worn microphone, guitar/instrument direct input and auxiliary units via the optional CL 2 line input cable. 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. Sennheiser miniature clip-on microphones can be attached in various ways: they can, for example, be attached to the hairline or to clothing (e.g. tie or lapel). However it is fixed, please make sure that the microphone is protected against sweat/moisture and make-up.

Squelch

Pilot tone squelch The transmitter adds a 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 signal, the receivers 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. In order to benefit from this feature, the pilot tone function must be activated on both the transmitter and the receiver. The pilot tone function is factorypreset to ON (= activated). Field strength-dependent squelch Depending on the strength of the received RF signal, the receivers 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).

Diversity reception

The EM 100 G2 receiver operates on the true diversity principle: A receiving antenna receives not only the electromagnetic waves which reach it by a direct path, but also the reflections of these waves which are created in the room by walls, windows, ceilings and fittings. When these waves are superimposed, destructive interference occurs, which can also be called field strength gaps. Repositioning the receiving antenna can bring a solution. With mobile transmitters, however (which all radiomicrophones are), the field strength gap will then occur with a different transmitter position. These field strength gaps can only be eliminated with true diversity receivers. In true diversity, instead of one antenna and one receiver there are now two antennas and two receiver sections. The antennas are spatially separated. By means of a comparison circuit, the receiver section with the strongest RF signal is always switched to the common AF output. The risk of the occurrence of field strength gaps in both antennas at the same time is virtually nonexistant. The receiver display panel shows the active diversity section (I or II).
