Product overview Status display 776.000 NAME The status display shows the receiving frequency, the transmitter battery status and – depending on the selection made in the “Display” menu – either the frequency bank and the channel number or the name of the receiver. With the EM 3732-II COM receiver, the command display can also be displayed within the status display. The contents of the status display can be changed in the “Display” menu (see page 38).
Product overview Command display (status display of the audio outputs AF and Command) AF COM The command display is only available with the EM 3732-II COM twin receiver. Besides the two audio outputs K and M the EM 3732-II COM twin receiver also features the two command outputs J and L.
Putting the receiver into operation Putting the receiver into operation Fitting the device feet To ensure that the receiver cannot slip on the surface on which it is placed, four self-adhesive soft rubber feet are supplied. Do not fit the device feet when rack mounting the receiver. CAUTION! Risk of staining of furniture surfaces! Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics.
Putting the receiver into operation The rack mount “ears” are already fitted to the receiver on delivery. To mount the receiver into a 19" rack: 왘 Slide the receiver into the 19" rack. 왘 Secure the rack mount “ears” 1 to the rack using four screws (not included in the delivery).
Putting the receiver into operation Mounting the antennas to the front of the rack To mount the antenna connections to the front of the rack when rack mounting the receiver, you require the GA 3030 AM antenna front mount kit (optional accessory). The GA 3030 AM consists of: W Y X • 2 BNC extension cables (screw-in BNC socket W to BNC connector [), • 2 antenna holders Z, • 4 screws, • 2 washers Y, • 2 nuts X. 왘 Unsecure the rack mount “ears” 1 from the rack.
Putting the receiver into operation Connecting and positioning remote antennas Use remote antennas when the position of the double receiver is not the best antenna position for optimum reception. Remote antennas are available as accessories. 왘 Connect the remote antennas to the BNC sockets O and R using a lowattenuation 50-Ω coaxial cable. N O P Q R S Ready-made coaxial antenna cables from Sennheiser are available as accessories with length of 1 m, 5 m and 10 m (see “Accessories” on page 45).
Putting the receiver into operation Connecting the receiver to the mains/ disconnecting the receiver from the mains CAUTION! Damage to the device due to electric current! If you connect the receiver to an unsuitable power supply, this can cause damage to the device. 왘 Use the supplied mains cable to connect the receiver to the mains (100 to 240 V AC, 50 or 60 Hz). 왘 Ensure a reliable mains ground connection of the receiver – especially when you are using multi-outlet power strips or extension cables.
Putting the receiver into operation Connecting devices with AES3 digital input The digital balanced XLR-3M audio output G outputs the signals of both receivers in AES3 format. 왘 Use a special double-shielded 110 Ω AES3 cable to connect the device with AES3 digital input to the digital balanced XLR-3M audio output G. This prevents that the digital data transmission interferes with RF reception.
Putting the receiver into operation Connecting the receivers to a PC via Ethernet The receivers can be centrally configured and monitored via a PC and the supplied “Wireless Systems Manager” software. Additionally, you can update the firmware in the receivers. If you want to connect several receivers to the same Ethernet socket of your network, you require a standard 100Base-T Ethernet switch.

Additional information Additional information HiDyn plus™ (HDP) noise reduction RF link Inherent noise of the RF link Transmitter Receiver This product family is equipped with HDP, the Sennheiser noise reduction system that reduces RF interference. It increases the signal-to-noise ratio in wireless audio transmission to more than 110 dB.
Additional information Diversity reception The receivers operate 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.
If a problem occurs If a problem occurs Problem Possible cause Possible solution No operation indication No mains connection Check the connections of the mains cable No RF signal Transmitter and receiver are not on the same channel Set transmitter and receiver to the same channel (see “Selecting a frequency bank and a channel” on page 30 and “Synchronizing a transmitter with the receiver frequency” on page 21).
