40 The EM 550 G2 twin receiver The EM 550 G2 twin receiver consists of two complete true diversity receivers in a single 19” rack housing. The two receivers can be operated independently from each other. The EM 550 G2 has an integrated antenna splitter, enabling you to daisy-chain up to eight twin receivers.
41 The channel bank “U” (user bank) allows you to store your selection out of 1,440 receiving frequencies that are freely selectable within the preset frequency range. Safety instructions Never open an electronic unit! If units are opened by customers in breach of this instruction, the warranty becomes null and void.

43 Overview of operating controls The EM 550 G2 consists of two complete receivers (RX A and RX B) in a 19” ra ck housing. The two receivers can be operated independently from each other, therefore all operating controls are available separately for each receiver.
44 Indications and displays Each receiver of the EM 550 G2 prov ides information on its own operating states and those of the received ew 500 G2 transmitter (remote displays).

48 Connecting the amplifier/mixing console The two audio outputs of the twin receiver are available as transformer balanced XLR-3M sockets. You can conn ect 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).
49 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.
50 Using the twin receiver Switching the twin receiver on/off Each receiver of the EM 550 G2 is sw itched on and off separately with the ON button. The receivers can only be swit ched off when the standard display is shown on the display panel.

56 Adjustment tips for the operating menu The following adjustment tips refer to the operating menus of both receivers of the EM 550 G2. 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.
57 Scanning the channel banks for free channels Scan Before putting one or several transmis sion links into operation, you should scan the channel banks for free channels.

58 Multi-channel operation Combined with ew 500 G2 transmitters, the receivers can form transmission links that can be used in multi-channel systems. 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.
59 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.

66 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.
67 Diversity reception The two receivers of the EM 550 G2 operat e 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.
