Connections - Balanced and Unbalanced

There are two basic types of audio system interconnections for very low to medium level audio signals: Balanced and unbalanced. Your EON10 G2 can accept either type of input.

Balanced Lines

In audio, a balanced line is a three-conductor system in which the two signal wires carry an equal, but opposite voltage with respect to the ground wire. The ground wire acts only as a shield and does not carry any audio signal current. Outside interference (such as RFI _ Radio Frequency Interference) is either shielded from the internal signal conductor, or if it gets into the cable, is

cancelled out by the opposite signals at the receiving end. Balanced connections are preferred for any longer cable runs.

Unbalanced Lines

Unbalanced cable is a two-wire system where the shield (ground wire) acts as one of the current carrying signal conduc- tors. The center conductor enclosed by the shield is commonly known as the “hot” conductor. Unbalanced audio cables do not reject noise as well as balanced lines. Unbalanced lines are typical in home hi-fi type systems and on the outputs of electronic musical instruments. These work well if the distance between the components is short, the signal level is relatively high and all of the electronics used in the system are plugged into the same AC service.

Unbalanced Sources to EON Powered Loudspeakers

If you need to connect your EON speakers to an unbalanced source you have two options:

•Use the INPUT 2 and INPUT 3 connectors. These inputs are balanced but will accept unbalanced inputs without the need for any special adapters.

•Use an adapter or special cable (see the section “Cables and Connectors”).

Loudspeaker Placement and Mounting

The following guidelines will help you achieve optimum sound wherever you use your EON loudspeakers:

Raise the speakers as high as possible. For best results try to get the high frequency horn at least 2 to 4 feet above the heads of the audience. If the speakers are too low, the people in the back of the audience will not receive the best quality of sound.

Place the speakers between the microphones and the audience. Feedback occurs when the microphones pick up sound from the speakers and “feed” the sound back through the sound system. If space is limited, point the speakers away from the microphones to reduce feedback.

Locate the speakers away from turntables. Low-frequency feedback occurs when the output of the speaker is picked up by the tone arm of the turntable and is re-amplified. A heavy, solid turntable base and shock mounting can also reduce this type of feedback in DJ applications.

Use more speakers in large or highly reverberant spaces. Spreading speakers throughout these spaces will produce much better sound than trying to compensate with loudness level or equalization. For very long distances, the use of another set of speakers on a delay is recommended.

Stand speakers upright for PA - Tilt the speakers back for stage monitoring. Upright stance provides even coverage over a wide area. EON speakers are also designed with two slanted positions for stage monitoring applications.

G2 specifications

JBL Professional G2 series speakers represent a new standard in sound reproduction, boasting a range of features and technologies that cater to both professional audio engineers and casual users. With an emphasis on clarity, power, and durability, the G2 series is ideal for live sound applications, installations, and studio monitoring.

One of the standout characteristics of the G2 series is its advanced driver technology. The speakers are equipped with JBL’s patented Differential Drive woofers, designed to provide high output while reducing distortion. This technology allows the speakers to deliver impressive low frequencies without compromising clarity across the mid and high ranges, ensuring a balanced sound experience. The high-frequency compression drivers are engineered to handle high sound pressure levels, making these speakers suitable for a variety of venues, from small clubs to large concert halls.

The G2 series also features a smart crossover design that optimizes the frequency range for both the woofer and tweeter, enabling seamless integration between the drivers. This results in a coherent and immersive soundstage, allowing listeners to experience music as it was intended. Additionally, the incorporation of high-quality materials in the speaker construction enhances durability, making the G2 series robust enough to withstand the rigors of touring and heavy usage.

Portability is another key aspect of the G2 series, as JBL has designed these speakers to be lightweight and easy to transport. Integrated handles and mounting points enhance usability during setup and breakdown, catering to the needs of mobile sound engineers. Furthermore, the speakers are available in various configurations, including passive and powered versions, allowing users to choose the best fit for their specific requirements.

Connectivity options are also flexible, with XLR and TRS inputs that enable easy integration into existing audio setups. The G2 series can accommodate a wide range of audio gear, ensuring compatibility across different systems.

In summary, JBL Professional G2 series speakers are engineered for high performance and reliability. Their combination of advanced driver technology, smart crossover design, and portable features make them a perfect choice for professionals seeking exceptional sound quality in any setting. Whether used for live performances, installations, or studio monitoring, the G2 series stands out as an industry leader, delivering powerful and pristine audio that resonates with both artists and audiences alike.
