See offline operation on page 13. Adjusting the audio channels Via the Mode menu item, you can adjust the audio channels.
Select Stereo if you want to transmit two separate audio signals on channel I and channel II (e.g. channel I = audio signal of the presenter/musician, channel II = sum of all audio signals). This allows the presenter/musician to adjust the balance between the left and right stereo signal on his receiver.
Select Mono if you only want to transmit an audio signal on one channel. In this case, the signal from the left audio input BAL AF IN L (I) is transmitted. Using the transmitter During mono operation, you have to deactivate the pilot tone evaluation on the EK 2000 IEM receiver in order to ensure that your receiver outputs the same signal on channel I and II. Monitoring the audio signal via headphones CAUTION!
You can monitor the audio signal via the headphone output . Danger of hearing damage!
Listening at high volume levels for long periods can lead to permanent hearing defects.

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. There are two transfer directions:
1. Easy Setup Sync: Transfer from the receiver to one or several transmitters Once you have performed a frequency preset scan with your 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 configure 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. 2. 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. Via the Sync Settings submenu, you can adjust the receiver parameters listed below and activate or deactivate their transfer to an EK 2000 IEM receiver. Setting Transferred receiver parameter Balance Current balance setting (15/+15) Squelch Current squelch setting (Off, 5 dB ... 25 dB) Mode Current audio mode setting (Stereo/Focus) High Boost Current treble boost setting (flat/High boost) Auto Lock Current lock mode setting (active/inactive) Limiter Current limiter setting (18 dB, 12 dB, 6 dB, Off) 15 Using the transmitter 16 When carrying out the Sync function, the transmitters current frequency bank and channel setting as well as the receiver parameters adjusted via the Sync Settings submenu are transferred to the EK 2000 IEM receiver via the infra-red interface.

Only use a transmitter and a receiver from the same frequency range (see the type plate on the transmitter and the receiver).
Make sure that the desired frequencies are listed in the enclosed frequency infor-
mation sheet.
Make sure that the desired frequencies are approved and legal in your country and, if necessary, apply for an operating license. Synchronizing the transmitter with an EK 2000 IEM receiver individual operation Upon delivery, transmitter and receiver are synchronized with each other. If, however, you cannot establish a transmission link between transmitter and receiver, you have to synchro-
nize the channels of the devices:
Carry out the Easy Setup Sync function and then the Sync function (see page 16). Alternatively, you can set the channel on the transmitter manually:

If you want to use the frequency banks U1 to U6:
Make sure to use transmitters and receivers from the same frequency range (see page 4 and the type plates of the devices). To ensure that the desired frequencies are intermodulation-free:
Contact your Sennheiser partner (see www.sennheiser.com).
Set each transmitter to the same frequency bank.
On one of the transmitters, select a channel within this frequency bank (see page 19).
Assign this channel one of the calculated transmission frequencies (see page 19).
Synchronize a receiver with your transmitter (
, see page 16)
Manually set the receiver to the same frequency bank, channel and frequency that you set OR on the transmitter.
Repeat for the remaining transmitters and receivers as described above. Cleaning the transmitter CAUTION!
Liquids can damage the electronics of the transmitter!
Liquids entering the housing of the device can cause a short-circuit and damage the electronics.
Keep all liquids away from the transmitter.
