With this series, Sennheiser offers high-quality state-of-the-art RF transmission systems with a high level of operational reliability and ease of use. Transmitters and receivers permit wireless transmission with studio-quality 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. 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. Commercial use is subject to the rules and regulations of the trade association responsible.
Areas of application The 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.

Preparing the receiver for use Inserting and replacing the batteries For powering the receiver, two 1.5 V AA size batteries are required. Press the two unlocking buttons battery compartment cover . and open the Insert the two batteries as shown above. Please observe correct polarity when inserting the batteries. Close the battery compartment. The battery compartment cover locks into place with an audible click.

Attaching the receiver to clothing The receiver is attached to clothing (e.g. belt, waistband) with the supplied belt clip. The clip is detachable so that you can also attach the receiver with the antenna pointing downwards. To do so, withdraw the clip from its fixing points and attach it the other way round.
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/OFF button will cancel your entry (ESC function) and return you to the standard display with the last stored settings. Note: Remove the batteries or the accupack when the receiver will not be used for extended periods of time. Press the two unlocking buttons battery compartment cover .
Attention! High volume! Even short exposure to high volume levels will damage your hearing! Set the volume for the connected headphones to the minimum before putting the headphones on. First, use the / rocker button to set the volume for the connected headphones to the minimum. Then gradually increase the volume. Volume up? – NO! When people use headphones, they tend to choose a higher volume than with loudspeakers. Listening at high volume levels for long periods can lead to permanent hearing defects.
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.

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. Each of the channel banks “1” to “8” has 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.
Use the / rocker button to select the desired receiving frequency. Your selection becomes effective immediately. Receiving frequencies are tunable in 25-kHz steps within a switching bandwidth of 36 MHz max. For intermodulation-free frequencies, please refer to the enclosed frequency table. Scanning the channel banks for free channels – SCAN Before putting one or several ew 500 G2 transmission links into operation, you should scan the channel banks for free channels.
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. The following figures are a guide to the best settings: y Line level input: 0 to +18 dB y Microphone level input: −24 to −6 dB Adjusting the squelch threshold – SQELCH The receiver is equipped with a squelch that can be adjusted via the “SQELCH” menu.
Selecting the standard display – DISLPY Via the “DISPLY” menu, you can select the standard display: Selectable standard display Contents of standard display “FREQ” “NAME” “CHAN” 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.
Activating/deactivating the pilot tone evaluation – PILOT Via the “PILOT” menu, you can activate or deactivate the pilot tone evaluation. The pilot tone supports the receiver’s squelch function (Squelch) and protects against interference due to RF signals from other units. The transmitter adds an inaudible signal, known as the pilot tone, to the transmitted signal. The receiver detects and evaluates the pilot tone, and is thus able to identify the signal of the matching transmitter and mute all others.

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 To avoid overmodulating the receiver, observe a minimum distance of 5 m between transmitting and receiving antennas. ... for multi-channel operation y For multi-channel operation, you can only use the channels in a channel bank.
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-to-noise ratio in wireless audio transmission to more than 110 dB.
when using multi-channel systems. Finally, UHF frequency ranges are being approved all over the world for radiomicrophone usage – in some countries licence-free. 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.
