The EM 550 G2 has an integrated antenna splitter, enabling you to daisy-chain up to eight twin receivers. The EM 550 G2 can be combined with transmitters of the ew 500 G2 series to make high-quality state-of-the-art RF transmission systems for professional applications.
Attention! High Volume! This is a professional transmission system. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.
Areas of application The EM 550 G2 twin receiver can be combined with transmitters of the ew 500 G2 series (SK 500 G2 bodypack transmitter, SKM 500 G2 radiomicrophone or SKP 500 G2 plug-on transmitter). The transmitters are available in the same five UHF frequency ranges and are equipped with the same channel bank system with factory-preset frequencies.
Overview of operating controls The EM 550 G2 consists of two complete receivers (RX A and RX B) in a 19” rack housing. The two receivers can be operated independently from each other, therefore all operating controls are available separately for each receiver.
Indications and displays Each receiver of the EM 550 G2 provides information on its own operating states and those of the received ew 500 G2 transmitter (remote displays). Indications and displays of the receivers “PILOT” display The “PILOT” display appears on the display panel when the pilot tone evaluation is activated (see “Activating/deactivating the pilot tone...

“MUTE” display The “MUTE” display appears on the display panel and the backlighting of the standard display switches from green to red. In addition, the text “MUTE” flashes in alternation with the standard display when the RF signal of the received transmitter is too weak, the received transmitter has been muted (with the pilot tone transmission or evaluation activated).
For connecting the antennas, use 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 “Accessories” on page 69).
Essential notes on mounting remote antennas: Position antennas in the same room in which the transmission takes place! Maintain a minimum distance of 50 cm from metal objects (including reinforced-concrete walls)! Maintain a minimum distance of 1 m between receiving antennas! Daisy-chaining up to eight twin receivers The twin receivers feature an integrated antenna splitter so that up to eight twin receivers can be daisy-chained without any additional antenna splitters...
Connecting the amplifier/mixing console The two audio outputs of the twin receiver are available as transformer balanced XLR-3M sockets. You can connect an amplifier or a mixing console to each audio output. Connect the amplifier/mixing console to the XLR-3M sockets AF OUT B (receiver RX B) or AF OUT A (receiver RX A).

Guide the BNC cable with the BNC connector through the hole on the rack mount “ear”. Hook the two rack mount “ears” to the rear panel of the twin receiver. Secure the rack mount “ears” to the twin receiver using two of the supplied recessed head screws (M 3x6) respectively.
Activating/deactivating the lock mode Each receiver of the EM 550 G2 has a lock mode that can be activated or deactivated via the operating menu (see “Activating/deactivating the lock mode” on page 61). The lock mode prevents that the receiver is accidentally...
The operating menu The operating menu is the same for both receivers of the EM 550 G2 and can be used almost intuitively. To ensure that adjustments to the settings can be made quickly and “without looking”, the necessary operating steps for the twin receiver and the ew 500 G2 transmitters are similar.
By way of example of the “Tune” menu, this section describes how to use the operating menu. The operating steps for adjusting the settings via the menu are similar for both receivers of the EM 550 G2. After switching the receiver RX A or RX B on, the standard display is shown on the display panel.

Switching between channel banks Bank Each receiver of the EM 550 G2 has nine channel banks between which you can switch via the “Bank” menu. The channel banks “1” to “8” have up to 20 switchable channels that are factory-preset to a receiving frequency (see “The channel bank system”...
Scanning the channel banks for free channels Scan Before putting one or several transmission links into operation, you should scan the channel banks for free channels. Displaying a list of all free channels Via the “Channel list“ menu, you can display the number of free channels for Scan all channel banks.

Doing the soundcheck Soundcheck By doing a soundcheck, you can check the reception area for field strength gaps (“dropouts”) which cannot be compensated for by the receiver’s diversity circuitry. You can do the soundcheck without the help of another person. Switch the transmitter on.

Transmitters of the ew 500 series (first generation) do not transmit a pilot tone and the receivers of the ew 500 series (first generation) cannot evaluate the pilot tone. Nevertheless, you can combine the EM 550 G2 receiver with a transmitter of the first generation. However, when combining...

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 twin receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable.
Wireless transmission systems With the ew 500 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 –...
Squelch Pilot tone squelch The ew 500 G2 transmitters add 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 pilot tone, the receiver’s audio output will remain muted, even if a strong RF signal is present.
Diversity reception The two receivers of the EM 550 G2 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.
