All of Sennheiser’s professional expertise and more than fifty years of experience have gone into the creation of this state-of-the-art product. Please take a few moments to read these instructions carefully. We want you to enjoy your new receiver quickly and to the full.
With the EM 3031-U and EM 3032-U receivers, Sennheiser offers the professional user high quality RF receivers with a high level of operational reliability and ease of use. The EM 3031-U and EM 3032-U receivers together with the suitable hand-held and pocket transmitters permit wireless transmission with studio quality sound.

AF level on the transmitter side in a ratio of 2:1 (related to dB), and expands it in an exactly the same way on the receiver side. The optimisation of the dynamic range and the supporting effect of the control amplifier in the transmitter effectively reduce modulation problems.
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”.
For use as a stand-alone receiver, it is recommended that the supplied telescopic antennæ are used. They 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.
Mounting the receiver into a rack With the two rack mount “ears“ supplied, the receiver can be mounted into a 19" rack (1 U). The rack mount “ears“ are screwed to the receiver on the left and right Note If you wish to connect the antennæ to the front side, you must now pull the cables of the GA 3030-AM antenna mount through the holes on the rack mount “ears“...
The best reception quality is obtained with the Sennheiser A12 AD-UHF active antenna. Antenna and receiver can be connected with a RG 58 co-axial cable. Ready made up antenna cables from Sennheiser are available as accessories with lengths of 1 m, 5 m and 10 m (see chapter 20) Attention! To supply the antenna booster integrated in the A12 AD-UHF active antenna, a direct voltage (which can not be switched off) is output via the antenna sockets.
Note A straw relief clamp is particularly important when the receiver is permanently rack mounted. Inside the rack there are often a large number of cables - a straw relief clamp bracket prevents the cables from pressing each other out.
The receiver is switched on with the ON / OFF switch . Display panel is now lit up to show that the receiver is switched on, and the last frequency set is shown (see chapter 10). The display “ “ (see chapter 13) is lit up .
With buttons you can now select a different frequency. The display always jumps to the next fixed frequency setting in the program. 8 channels are allocated to each range. The 4 possible ranges are always shown by the display in display panel Have you set the frequency correctly? Then press button (“...
Selection and combination of possible receiving frequencies Each EM 3031 receiver (or each of the two EM 3032 receivers) can be programmed with a maximum of 32 receiving frequencies within the switching bandwidth. These receiving frequencies are divided into 4 groups.
Number of receiving frequencies For ease of use, or if required by country-specific restrictions on the frequency usage, it is also possible to program less than 32 receiving frequencies. Your local Sennheiser distributor will be happy to help you in the selection of your receiving frequencies.
( V) and the level control of the AF signal – i.e. the modulation of the RF signal (in %) are shown. Both displays have an overmodulation display. If the signal is too high, the text “PEAK“ lights up briefly. Short overmodulation is not critical.
This receiver also features AMF (Advanced Muting Function). This special electronic feature comes into effect when an RF signal drops by about 50 dB in a short time. The reception is then muted for 3 seconds. AMF thus suppresses the annoying switch-off click when a transmitter is switched off.
The Sennheiser HD 25 headphone is especially usefull for this purpose. In order to judge the quality of the received sound signal even under unfavourable conditions (low AF level in the transmitter) and with high ambient noise (e.g. on the stage), the sound signal at socket can be monitored at an amplification of up to 30 dB compared with the LINE output.
A faulty fuse should always be regarded as a warning. In most cases, the cause is harmless – a short voltage surge or some similar cause has triggered the protective mechanism. When the fuse has been replaced, the receiver works again.
This information can be evaluated with the EM 3031 / EM 3032 receivers. When the battery capacity is so low that only a transmission time of about 20 to 30 minutes BATT“ flashes on the display panel remains, the text “LOW...
Suitable Sennheiser transmitters For the optimum use of the excellent reception qualities of the EM 3031 / EM 3032 receivers, Sennheiser offers hand-held and pocket transmitters in a variety of configurations: Pocket transmitters: SK 1063-U (without display of battery condition)
