Replacement parts When replacement parts are required, be sure the service technician uses replacement parts specified by Sennheiser or those having the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
Important safety instructions Intended use Intended use of the ew 300 G3 series products includes: • having read these instructions especially the chapter “Important safety instructions”, • using the products within the operating conditions and limitations described in this instruction manual. “Improper use” means using the products other than as described in this instruction manual, or under operating conditions which differ from those described herein.
The EM 300 G3 rack-mount receiver The EM 300 G3 rack-mount receiver This receiver is part of the evolution wireless series generation 3 (ew G3). 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 studioquality sound.
The EM 300 G3 rack-mount receiver The devices are available in the same UHF frequency ranges and are equipped with the same frequency bank system with factory-preset frequencies. An advantage of the factory-preset frequencies is that • a transmission system is ready for immediate use after switch-on, • several transmission systems can be operated simultaneously on the preset frequencies without causing intermodulation interference.
The EM 300 G3 rack-mount receiver Each of the channels in the frequency banks “1” to “20” has been factorypreset 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 EM 300 G3 product page on our website at www.sennheiser.

Putting the receiver into operation Putting the receiver into operation Preparing the receiver for use Recommendations for optimum reception To ensure optimum reception even under difficult conditions, we recommend connecting remote antennas and, if necessary, using antenna splitters (see “Accessories and spare parts” on page 52). When rack-mounting the receiver, you can mount the supplied antennas to the front of the rack by using an antenna front mount kit.
Putting the receiver into operation 왘 Secure the rack mount “ears” to the sides of the receiver using the previously removed recessed head screws (see right-hand diagram). Fitting the device feet Do not fit the device feet when mounting the receiver into a 19” rack. 왘 Clean the base of the receiver where you want to fix the device feet. 왘 Fit the device feet to the four corners of the receiver as shown. 왘 Place the receiver on a flat, horizontal surface.
Putting the receiver into operation Mounting the receiver into a 19” rack Do not fit the device feet when mounting the receiver into a 19” rack. CAUTION! Risks when rack mounting the receiver! When installing the device in a closed or multi-rack assembly, please consider that, during operation, the ambient temperature, the mechanical loading and the electrical potentials will be different from those of devices which are not mounted into a rack.
Putting the receiver into operation 왘 Connect the antennas. You have the following options: – You can connect the supplied rod antennas to the rear of the receiver (see page 13). In this case, insert the two blanking plugs into the holes of the blanking plate (see diagram above). – You can use the AM 2 antenna front mount kit (see “Accessories and spare parts” on page 52) and mount the rod antennas to the blanking plate (see diagram below).
Putting the receiver into operation To mount the receiver into a 19” rack: 왘 Slide the receiver with the mounted blanking plate into the 19” rack. 왘 Secure the rack mount “ears” to the 19” rack. If you are using the supplied rod antennas: 왘 Align the antennas in a V-shape to obtain the best possible reception.
Putting the receiver into operation To mount the antennas: 왘 Use remote antennas, if necessary in conjunction with the ASA 1 antenna splitter (see “Accessories and spare parts” on page 52).

Synchronizing transmitters with receivers Synchronizing transmitters with receivers When synchronizing a transmitter with a receiver, please observe the following: 왘 Only use a transmitter and a receiver from the same frequency range (see the type plate on the transmitter and the receiver). 왘 Make sure that the desired frequencies are listed in the enclosed frequency information sheet.
Synchronizing transmitters with receivers Synchronizing transmitters with receivers – multi-channel operation In order to ensure an intermodulation-free transmission, use the same frequency bank for all transmission links. Network operation Combined with ew 300 G3 transmitters, ew 300 G3 receivers can form transmission links that can be used in multi-channel systems. In multi-channel operation, the receivers are remote controlled via a PC running the “Wireless Systems Manager” (WSM) software.
Synchronizing transmitters with receivers 왘 With one of the receivers, perform a frequency preset scan to scan the frequency banks for unused channels (“Scan New List”, see page 34). Then “Sync” appears on the display panel of the receiver. PEAK 40 30 20 10 RF 0 -10 -20 -30 -40 AF Easy Setup ew300 G3 B.Ch: 20.24 Sync 531.375 MHz 왘 Switch one of the transmitters on. 왘 Synchronize this transmitter with the receiver via the infra-red interface (see page 22).
Synchronizing transmitters with receivers 왘 On one of the receivers, select a channel within this frequency bank (see page 38). 왘 Assign this channel one of the receiving frequencies (see page 38). 왘 Synchronize a transmitter with the receiver (see page 22). OR 왘 Manually set the transmitter to the same frequency bank, channel and frequency that you set on the receiver. 왘 Repeat for the remaining transmitters and receivers as described above.
Cleaning the receiver Cleaning the receiver CAUTION! Liquids can damage the electronics of the receiver! Liquids entering the housing of the receiver can cause a short-circuit and damage the electronics. 왘 Keep all liquids away from the receiver. 왘 Before cleaning, disconnect the receiver from the mains. 왘 Use a cloth to clean the receiver from time to time. Do not use any solvents or cleansing agents.
Recommendations and tips Recommendations and tips ... 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 EM 300 G3 receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable.
If a problem occurs ... If a problem occurs ... Problem Possible cause Possible solution Receiver cannot be operated, “Locked” appears on the display panel Lock mode is activated Deactivate the lock mode (see page 23). No operation indication No mains connection Check the connections of the mains unit. No RF signal Transmitter and receiver are not Set the transmitter and receiver on the same channel to the same channel. To do so, use the synchronization function (see page 22).
If a problem occurs ... Problem Possible cause Possible solution Audio signal is distorted Transmitter sensitivity is adjusted too high Adjust the transmitter sensitivity correctly (see the instruction manual of the transmitter). Receiver’s audio output level is adjusted too high Reduce the audio output level (see page 36).
