The lock mode icon PEAK PEAK flashes prior to the lock mode being activated again. 0 -10 -20 -30 -40 AF I 0 -10 -20 -30 -40 AF II B. Ch: 5. 14 **2000** 552. 300 MHz EQ Standard -18dB Activating/deactivating the RF signal To deactivate the RF signal: When the standard display is shown on the display panel, press the STANDBY button. "RF Mute On?" appears on the display panel. 14 Using the transmitter Press the jog dial. In addition, the display backlighting changes from orange to red and "RF Mute" flashes in alternation with the standard display. To activate the RF signal: Press the STANDBY button. "RF Mute Off?" appears on the display pane. The RF signal is activated and the transmission icon backlighting changes from red to orange. To deactivate the RF signal on switch-on: See "offline operation" on page 13. The display Monitoring the audio signal via headphones CAUTION!Listening at high volume levels for long periods can lead to permanent hearing defects. Set the headphone volume control » to the minimum position before putting the headphones on. Do not continuously expose yourself to high volumes. PEAK PEAK Set the headphone volume control » to the minimum position. Connect headphones with a ¼" (6. 3 mm) stereo jack plug to the headphone output ·. Gradually increase the volume and monitor the audio signal with the lowest possible volume. Stereo Transmitter SR 2000 IEM 0 -10 -20 -30 -40 AF I 0 -10 -20 -30 -40 AF II Synchronizing transmitters and EK 2000 IEM receivers via the infra-red interface Synchronization allows you to quickly and easily transfer transmitter and receiver settings from one device to the other, especially if you want to configure a multi-channel system. Easy Setup Sync: Transfer from the receiver to one or several transmitters Once you have performed a frequency preset scan with a receiver, you can use the Easy Setup Sync function to transfer unused frequency presets from the receiver to the transmitters via the infra-red interface. In order to set up a multi-channel system, you use the diversity receiver to transfer the first unused channel from the selected frequency bank to the first transmitter and the next unused channel to the second transmitter and so on, thus ensuring that all transmitters of a multi-channel system operate on suitable frequencies. Sync: Transfer from a transmitter to a receiver Once you have selected and set the desired receiver settings on the transmitter (either manually or using the Easy Setup Sync function), you transfer these settings to a receiver. This configures the receiver and establishes a transmission link between transmitter and receiver. 15 Using the transmitter When carrying out the Sync function, the transmitter's current frequency bank and channel setting as well as the receiver parameters adjusted via the "Sync Settings" submenu (see page 27) are transferred to the EK 2000 IEM receiver via the infra-red interface. Carrying out an Easy Setup Sync or a Sync function The following assumes that you are using the Easy Setup Sync function for setting up a multichannel system. You can also use the Easy Setup Sync function for establishing a transmission link between one transmitter and one EK 2000 IEM receiver. Easy Setup Sync Switch all transmitters and one receiver on. On all transmitters, call up the "Easy Setup" menu item. [. . . ] Increase the transmission power (see page 19). Reduce the squelch threshold (see the instruction manual of the receiver). RF signal available, no audio signal at the receiver No input signal at the transmitter Very low input signal Check the audio level on the transmitter display (see page 7) Check the audio level on the transmitter display (see page 7), increase the level of the input signal or adjust the input sensitivity (see page 19). Audio signal has a high level of Transmitter sensitivity is adjusted Adjust the transmitter sensitivity correctly background noise too low (see page 19). Audio signal is distorted If "AF PEAK" additionally appears on the transmitter display: transmitter sensitivity is adjusted too high Receiver's audio output level is adjusted too high Adjust the transmitter sensitivity correctly (see page 19). Reduce the audio output level of the receiver.
