Operation: Frequency Considerations

The successful operation of an RF wireless system greatly depends on two things:

1)The frequencies used must avoid interference from competing signals, such as television broadcast.

2)The frequencies used must not interfere with each other. Selected frequencies need to be carefully calculated for sufficient spacing, and to avoid creating disruptive interference known as intermodulation.

Geographic location plays a major role in the performance of your wireless system. The primary source of competition is television broadcast transmission towers. It is likely that one or more television stations will be broadcasting within range of your wireless system, creating sources of interference. In planning your systems’ frequency requirements, it is advisable to determine what frequencies are in use by local television stations. Sennheiser’s website, www.sennheiserUSA.com, has an interactive Frequency Finder which can assist in identifying the local TV stations broadcasting in your area.

Local television stations are not the only source of interference, so having a complete knowledge of your RF environment is an important step in planning your wireless microphone system.

To provide users with additional flexibility to avoid interference, evolution wireless G3 systems are available in three distinct frequency ranges (A, G, B). Each range contains 1,680 user-selectable frequencies and 20 “Banks” of coordinated frequency presets, known as “Channels.” For proper multi-channel setup, all units in a frequency range should be set to the same Bank, each to a different available Channel.

All G3 systems include an easy-to-use EASY SETUP process, which ensures your units are set to fully compatible frequencies that avoid local interference.

Easy Setup / Scan New List:

1.On the receiver, press SET to enter menu. Press up/down buttons to select “Easy Setup”. Press SET and choose “Scan New List.” Press SET to start scan.

2.After the scan is complete, the receiver will recommend the “Bank” with the most “Channels” free. Press SET. Select a Channel using the up/down arrows and press SET to confirm. The receiver will say “STORED.”

3.Tap the POWER button to exit the menu. The new selected frequency will be displayed. You should see little to no RF activity on the meter (meaning, you are on a free channel).

4.Power up the transmitter you wish to pair with the receiver. Locate the transmitter’s infrared (IR) port. On a G3 handheld transmitter, the port is located on the LCD display. On a bodypack transmitter, it is located inside the battery compartment, to the right of the ON/OFF button.

5.For a rack-mount (EM) receiver, press the “SYNC” button on the front of the receiver. On a portable (EK) receiver, press SET and use the up/down button to find “Sync.” Press SET. Hold the transmitter‘s IR port in front of the receiver’s IR port, which is located on the left side of the display. Be sure to align the IR ports so they face each other, approximately 1” to 2” apart.

6.If the SYNC is successful, you will see a "" on the receiver screen. If you see an “X”, SYNC failed and you should repeat step 5.

7.After a successful SYNC, you should see the same frequency displayed on both the receiver and transmitter.

8.If setting up another system in the same frequency range (A/B/G), you can repeat the process from Step 1. Make sure to choose the same BANK number as you did in step 2 to ensure compatible operation, and a different channel number.

This broad range ensures that both low and high frequencies are accurately reproduced, allowing performers to hear their mix in incredible detail. The system is equipped with a powerful UHF transmitter that offers exceptional transmission stability, even in complex RF environments. This ensures that users experience minimal dropouts or interference, critical for effective in-ear monitoring during performances.

Another significant aspect of the ew 300IEM G3 is its versatility. The system supports up to 16 compatible frequencies, enabling multiple systems to operate simultaneously without conflict. This is especially useful in larger settings, such as concerts or festivals, where multiple performers may require monitoring at the same time. The wireless range of up to 100 meters allows performers the freedom to move around the stage without being tethered to a wired system.

The ew 300IEM G3 also incorporates an intuitive setup process, thanks to its user-friendly interface and easy-to-navigate menu. The clear LCD display provides real-time information on battery life, frequency settings, and signal strength, allowing users to monitor their system effectively. The built-in diversity reception minimizes the risk of dropouts, as the receiver alternates between two antennas for the best signal quality.

Comfort is paramount for in-ear monitoring, and Sennheiser addresses this with customizable in-ear buds that fit snugly, ensuring effective passive noise isolation. The system supports a variety of ear tips and accessories, allowing users to find the perfect fit for their ears.
