Connecting a remote antenna to the BNC socket and positioning the antenna
Use a remote antenna when the transmitter position is not the best antenna position for
optimum transmission. You can choose between two antennas:
• A 2003 UHF passive directional antenna
• A 1031 passive omni-directional antenna
̈ Use a low-attenuation 50-Ω cable to connect the antenna to the transmitter.
̈ If possible, use a short antenna cable and as little connections as possible, since long
cables and many connectors lead to an attenuation of the antenna signal.
̈ Position the antenna in the same room in which the transmission takes place.
̈ Observe a minimum distance of 1 m between the antenna and metal objects (including
reinforced concrete walls).
Connecting the AC 3 antenna combiner to the BNC socket
To make multi-channel systems, you should use the AC 3 antenna combiner (optional
accessory). The AC 3 allows you to operate up to four transmitters with a single antenna
without virtually any intermodulation. In addition, the AC 3 incorporates DC distribution to
enable simultaneous powering of up to four transmitters via its BNC sockets.

Daisy chaining audio signals
You can transmit the same audio signal (e.g. the sum of all audio signals) to several diversity
receivers of a multi-channel system. To do so, you have to daisy chain this audio signal from
one transmitter to the next via the output sockets LOOP OUT BAL L(I) ¹ or
LOOP OUT BAL R(II) Ƹ. The audio signal is then transmitted by all transmitters on one of the
two audio channels L(I) or R(II). The second audio channel allows you to transmit an
individual audio signal (e.g. the instrument of a musician). Using the balance setting on the
receiver, you can then adjust the relative levels of the sum of all audio signals and the
individual audio signal. For this, the transmitter has to be set to stereo mode and the receiver
to Focus mode.

Using the devices
Synchronizing transmitters and EK 300 IEM G3 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 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 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 300 IEM G3 receiver.
Setting
Transferred receiver parameter
“Balance”
“Squelch”
“Mode”

“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”)
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 are transferred to the EK 300 IEM G3 receiver via the infra-red interface.
