Transmitters and receivers permit wireless transmission with studioquality sound.
Safety instructions Never open an electronic unit! If units are opened by customers in breach of this instruction, the warranty becomes null and void. Keep the unit away from central heating radiators and electric heaters. Never expose it to direct sunlight. Use the unit in dry rooms only. Use a damp cloth for cleaning the unit. Do not use any cleansing agents or solvents. Attention! High Volume! This is a professional transmission system.
Areas of application The EM 500 G2 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.

Indications and displays When used together with an ew 500 G2 transmitter, the receiver provides information on its operating states and those of the received transmitter (remote displays). Indications and displays of the receiver “PILOT” display The “PILOT” display appears on the display panel when the pilot tone evaluation is activated (see “Activating/deactivating the pilot tone evaluation” on page 23).
“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 y the RF signal of the received transmitter is too weak, y the received transmitter has been muted (with the pilot tone transmission or evaluation activated). Modulation display The level display for audio signal “AF” shows the modulation of the received transmitter.
Preparing the receiver for use Mounting the receiver feet To ensure that the receiver cannot slip on the surface on which it is placed, four self-adhesive soft rubber feet are supplied. Ensure that the base of the receiver is clean and free from grease before mounting the rubber feet. Fix the rubber feet to the base of the receiver by peeling of the safety paper and fitting them as shown in the digram on the left.
Connecting the amplifier/mixing console The receiver’s audio outputs are available as an XLR-3M socket and a ¼” (6.3 mm) jack socket , allowing you to simultaneously connect two units (e.g. amplifier, mixing console). The adjusted audio output level is common for both sockets. Connect the amplifier/mixing console to the XLR-3M socket or the ¼” (6.3 mm) jack socket . For detailed information on balanced and unbalanced connection, please refer to the section “Connector assignment” on page 30.
To mount two receivers into a rack: Place the two receivers side by side onto a flat surface, their bottom sides facing upwards. Align the connecting plate over the holes in the bottom sides of the receivers. Secure the connecting plate to the receivers using eight of the supplied recessed head screws (M 3x6). Hook the two rack mount “ears” to the front panels of the receivers.
Using the receiver Switching the receiver on/off The receiver can only be switched off when the standard display is shown on the display panel. When in the operating menu, briefly pressing the ON button will cancel your entry (ESC function) and return you to the standard display with the last stored settings. Press the ON button to switch the receiver on. % To switch the receiver off, press the ON button until “OFF” appears on the display.
The operating menu A special feature of the Sennheiser ew 500 G2 series is the similar, intuitive operation of transmitters and receivers. As a result, adjustments to the settings can be made quickly and “without looking” – even in stressful situations, for example on stage or during a live show or presentation.

Working with the operating menu By way of example of the “Tune” menu, this section describes how to use the operating menu. After switching the receiver on, the standard display is shown on the display panel. Getting into the operating menu Press the SET button to get from the standard display into the operating menu. The last selected menu and its current setting are displayed with a background. Selecting a menu Press the / rocker button to select a menu.

Adjustment tips for the operating menu Switching between channel banks Bank Via the “Bank” menu, you can switch between the receiver’s nine channel banks. 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” on page 4). The channel bank “U” (user bank) has up to 20 switchable channels to store your selection out of 1440 receiving frequencies that are freely selectable within the preset frequency range.
Displaying a list of all free channels Via the “Channel list“ menu, you can display the number of free channels for all channel banks.

Set all transmitter/receiver pairs in you multi-channel system to the free channels in this channel bank. Adjusting the audio output level AF Out Via the “AF OUT” menu, you can adjust the audio output level of the receiver. The level can be adjusted in eight steps. Adapt the level of the audio output (AF OUT) to the input of the connected unit.
Select the “Soundcheck” menu. The soundcheck is started immediately. With the transmitter, walk up and down the transmission area. Press the button on the receiver to terminate the soundcheck and to display the result of the soundcheck. The level displays “RF” and “AF” will indicate the lowest RF and the highest AF level of the received transmitter. Optimize the RF level by repositioning the receiving antennas. The audio level should be as high as possible (max.
Entering a name Name Via the “Name” menu, you can enter a freely selectable name for the receiver. You can, for example, enter the name of the performer for whom the adjustments have been made. The name can be displayed on the standard display and can consist of up to ten characters such as: y letters (without pronounciation marks), y numbers from 0 to 9, y special characters e.g. () - . _ and spaces.
Activating/deactivating the lock mode Lock Via the “Lock” menu, you can activate or deactivate the lock mode. The lock mode prevents that the receiver is accidentally programmed or switched off during operation. The lock mode icon on the display indicates that the lock mode is activated. To deactivate the lock mode, first press the SET button and then press the / buttons to select “Off”. If you confirm your selection by pressing the SET button, the buttons can be operated as usual.

Recommendations and tips ... for optimum reception y 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. y If, with the EM 500 G2 receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable. y To avoid overmodulating the receiver, observe a minimum distance of 5 m between transmitting and receiving antennas.
Additional information HDX noise reduction RF link Inherent noise of the RF link Transmitter Receiver Progress you can hear: The evolution wireless G2 series is equipped with HDX, the Sennheiser noise reduction system that reduces RF interference. It increases the signal-tonoise ratio in wireless audio transmission to more than 110 dB.
Squelch Pilot tone squelch The ew 500 G2 transmitters adds 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. This prevents strong interfering signals from causing hissing noise in the receiver when the transmitters are switched off.
